The aim of this study was to characterize the microbial diversity contaminating plant leaves used as food packaging. In total, two hundred and forty (240) samples composed of Thaumatococcus daniellii and Musa paradisiaca leaves were collected and analyzed. Microbial diversity was assessed using specific medium and biochemical tests. The resistance profile was determined by the Müeller-Hinton agar diffusion method. The resistance (blaSHV, blaIMP, blaTEM) and biofilm formation (pslA, pelA) genes were searched by PCR method. Plant leaves were contaminated by bacterial (68.7%) and fungal (100%) strains. Extreme bacterial (7.1 log10 cfu/cm2) and fungal (3.5 log10 cfu/cm2) loads were obtained on Thaumatococcus daniellii leaves. Bacterial prevalence was 45.1% (S. aureus), 38.8% (E. coli) and 16.1 (P. aeruginosa). In order of decreasing importance, the prevalence of fungal species was 41.1% (A. flavus), 33.1% (A. fumigattus), 13.7% (A. niger) and 12.1% Candida sp. Resistance of E. coli to penicillins ranges from 31.6% to 87.3% and to cephalosporins from 13.3% to 28%. The P. aeruginosa strains were mainly resistant to aztreonam (87.6%). Those of S. aureus showed resistance to tetracycline (67.6), vancomycin (53), erythromycin (44.6) and levofloxacin (32.7). The blaSHV (14.28% to 18.60%) and blaIMP (9.52% to 16.28%) genes were detected in the bacterial strains. P. aeruginosa strains (19.05%) harbored the pslA and pelA genes. The health safety of these biodegradable plant-based packaging contributes to their valorization.展开更多

Green tea phenolic compounds are predominately composed of catechin derivatives, although other compounds such as flavonols and phenolic acids are also present in lower proportion. The bioactivity exerted by these compounds has been associated with reduced risk of severe illnesses such as cancer, cardiovascular and neurodegenerative diseases. Particularly, epigallocatechin gallate has been implicated in alteration mechanisms with protective effect in these diseases as indicated by several studies about the effect of green tea consumption and mechanistic explanation through in vitro and in vivo experiments. The biological activity of green tea phenolic compounds also promotes a protective effect by antioxidant mechanisms in biological and food systems, preventing the oxidative damage by acting over either precursors or reactive species. Extraction of phenolic compounds influences the antioxidant activity and promotes adequate separation from green tea leaves to enhance the yield and/or antioxidant activity. Application of green tea phenolic compounds is of great interest because the antioxidant status of the products is enhanced and provides the product with additional antioxidant activity or reduces the undesirable changes of oxidative reactions while processing or storing food.In this scenario, meat and meat products are greatly influenced by oxidative deterioration and microbial spoilage, leading to reduced shelf life. Green tea extracts rich in phenolic compounds have been applied to increase shelf life with comparable effect to synthetic compounds, commonly used by food industry. Green tea has great importance in general health in technological application, however more studies are necessary to elucidate the impact in pathways related to other diseases and food applications.展开更多

They have vasoactive, psychoactive and toxicological characteristics and constitute a potential health risk. The concentration of amines formed in foods depends on the type of microorganisms present, the action of decarboxylase enzymes produced by microorganisms on specific amino acids and favorable conditions for enzymatic activity. The presence of these chemical metabolites has been suggested as a quality indicator in routine analyzes for food production and marketing monitoring. The detection of bioactive amines can be performed by chromatographic methods, fluorometric and enzymatic kits. Bioactive amine formation can be prevented mainly through the adoption of good manufacturing practices, but the industry can also use other methods such as temperature control in the production chain, modified atmosphere packaging and food irradiation. This review aims to address the formation of bioactive amines in foods, emphasizing the formation and classification of these metabolites, aspects related to health, acceptable limits, detection methods and control methods used in the industry to ensure food safety and quality. The success of this approach is linked to the importance of bioactive amines as quality indicators, as well as the discussion on the development of methodologies for determining these substances and discussion of acceptable parameters in food.展开更多

Maize, soybean and peanut were blended in a ratio of 60:30:10 to produce a complementary food, which was then fortified. While the unfortified food product (sample A) served as control, the other three formulations were fortified with 5%, 10% and 15% Moringa leaf powder to give three samples (B, C and D respectively) of fortified food. Nutritional composition determination and feeding trials were then carried out, using two weeks old male albino rats to determine the performance of the food formulations. While the crude protein, crude fibre, and ash contents of the diets increased significantly (p with fortification, with values ranging from 16.04% to 17.59%, 2.25% to 4.42% and 1.40% to 2.50% respectively, crude fat and carbohydrate decreased significantly (p < 0.05), with concomitant decrease in energy, with values ranging from 23.48% to 20.80%, 49.32% to 47.63% and 472.76% to 448.08 kcal/100g respectively in samples A to D. PER values significantly (p < 0.05) improved up to 10% substitution, from 1.77 in unfortified (sample A) to 1.90 in 10% fortified (sample C), but declined at 15% substitution (sample D) to 1.69. Similarly, NPR values increased from 0.71 to 0.76 and 0.68. However, all the PER values including that of Nestle Cerelac (2.04) were lower than, though within the same range, with the value of 2.10 recommended by the Protein Advisory Group (PAG) for complementary foods. Sample C (10% Moringa flour blend) gave the best performance after rat feeding trials.展开更多

The reaction of chlorine species with organic matter is a concern for two reasons. Available chlorine can be “used up” by organic compounds resulting in a lower amount of chlorine available for disinfection. Another concern is that some forms of chlorine can react with some organic compounds to form toxic halogenated disinfection byproducts（DBPs）. Many studies have been conducted to evaluate the role of hypochlorous acid（HOCl） and hypochlorite ion（OCl–） in the production of DBPs with a particular interest in the production of trihalomethanes（THMs） and haloacetic acids（HAAs）. Since most of the chlorine reactions are pH dependent, pH is found to have a significant effect on the formation of chlorine DBPs. In many cases, the concentration of THMs decreases and HAAs increases as pH decreases. pH also plays an important role in the determination of the type and amount of DBPs formed, with lower, more acidic, pHs resulting in the formation of less chloroform. This review summarizes the information from the literature on the role of chlorine-based sanitizers as affected by pH in the formation of different types of DBPs. Alternative novel strategies to minimize the formation of DBPs are also discussed.展开更多

All of these isolates were muti-drug resistant with high MAR index. The results showed that C. compressa extract exhibited better and stronger antibacterial activities against the seventeen tested isolates with inhibition zones diameter ranged from 14 - 22 mm compared to P. pavonica extract which showed positive effect against 9 isolates with low inhibition zone ranged from 11 - 16.5 mm. Flavonoids extracted from C. compressa also displayed the best spectrum of bactericidal effect with a ratio MBC/MIC ≤ 4 obtained on all susceptible tested bacterial strains. Flavonoids and proanthocyanidins significantly contributed to the antibacterial properties. The mode of action of these active extracts is under investigation.展开更多

Tomato ketchup potato chips (TKPC) color sweet and color chocolate at low (15%) and high (30%)) concentration on serum biochemical, WBC (white blood cell)and histopathology of liver and kidney of rats for 13 week. The results indicated that no significant change in body weight gain, serum glucose, HDL and LDL cholesterol. TKPC (30%) showed that significant increase in total cholesterol (TC), triacylglycerol (TG). Low and high concentration of color chocolate and color sweet was exhibited significant increase of TG. The level of ALT and AST was significant increase of rat’s administration color fruit juice (for 12 hr.) and TKPC at 30%. High concentration of color foods and long time administration of color fruit juice showed significant increase in serum creatinine and albumin compared to control group. Both low and high consumed of color foods exhibited significant decrease in liver GSH. High concentration of color foods lead to increase number of WBC as the result to the response of the immune system to the inflammation. Color foods were reveled change in histological structure of liver and kidney. In conclusion, the use synthetic color in various foods has adverse effect on some of biochemical analysis;and the liver and kidney histopathological structure.展开更多

文摘Despite their biodegradability and economic advantage, plant leaves used as packaging can constitute a public health problem. The aim of this study was to characterize the microbial diversity contaminating plant leaves used as food packaging. In total, two hundred and forty (240) samples composed of Thaumatococcus daniellii and Musa paradisiaca leaves were collected and analyzed. Microbial diversity was assessed using specific medium and biochemical tests. The resistance profile was determined by the Müeller-Hinton agar diffusion method. The resistance (blaSHV, blaIMP, blaTEM) and biofilm formation (pslA, pelA) genes were searched by PCR method. Plant leaves were contaminated by bacterial (68.7%) and fungal (100%) strains. Extreme bacterial (7.1 log10 cfu/cm2) and fungal (3.5 log10 cfu/cm2) loads were obtained on Thaumatococcus daniellii leaves. Bacterial prevalence was 45.1% (S. aureus), 38.8% (E. coli) and 16.1 (P. aeruginosa). In order of decreasing importance, the prevalence of fungal species was 41.1% (A. flavus), 33.1% (A. fumigattus), 13.7% (A. niger) and 12.1% Candida sp. Resistance of E. coli to penicillins ranges from 31.6% to 87.3% and to cephalosporins from 13.3% to 28%. The P. aeruginosa strains were mainly resistant to aztreonam (87.6%). Those of S. aureus showed resistance to tetracycline (67.6), vancomycin (53), erythromycin (44.6) and levofloxacin (32.7). The blaSHV (14.28% to 18.60%) and blaIMP (9.52% to 16.28%) genes were detected in the bacterial strains. P. aeruginosa strains (19.05%) harbored the pslA and pelA genes. The health safety of these biodegradable plant-based packaging contributes to their valorization.
文摘Cancer continues to pose a substantial public health problem in Nigeria,characterized by rising rates of occurrence and mortality.While there is increasing interest in using natural products for cancer treatment,comprehensive data on the specific bioactive compounds in these plants and how they modulate different types of cancer are still lacking.Additionally,although traditional knowledge about these food plants is rich and valuable,it has not been fully integrated with modern scientific research to create standardized treatment protocols.Scientific databases like PubMed,ScienceDirect,Google Scholar,and ResearchGate were explored to retrieve empirical data.The key plants discussed are Spondias mombin,Xanthosoma sagittifolium,Elaeis guineensis,Irvingia gabonensis,Allium cepa,Blighia sapida,Dioscorea dumetorum,Psidium guajava,and Talinum triangulare.These plants demonstrate a wide range of anticancer properties,including the ability to induce apoptosis(cell death),halt the cell cycle,inhibit angiogenesis,and regulate inflammatory responses.They contain a variety of phytochemicals,such as flavonoids,tannins,terpenoids,alkaloids,and organosulfur compounds,which contribute to their anticancer effects.For example,Spondias mombin contains flavonoids that inhibit the formation of tumors,whereas Xanthosoma sagittifolium exhibits cytotoxic effects against leukemia cells.Additionally,Elaeis guineensis exhibits antioxidant properties that counteract oxidative stress,a crucial factor in cancer progression.This review highlights the significance of these plants in developing complementary cancer therapies that can be used alongside conventional treatments.By combining traditional knowledge with contemporary scientific methods,these medicinal plants have the potential to provide innovative approaches to cancer prevention and treatment,addressing the pressing demand for safer and more efficient therapeutic alternatives.
文摘Red chilli powder(RCP)is a versatile spice accepted globally in diverse culinary products due to its distinct pungent characteristics and red colour.The higher market demand makes the spice vulnerable to unethical mixing,so its quality assessment is crucial.The non-destructive application of computer vision for measuring food adulteration has always attracted researchers and industry due to its robustness and feasibility.Following the current era of Food Quality 4.0 and artificial intelligence,this study follows an approach based on 1D-convolutional neural networks(CNN)and 2D-CNN models for detecting RCP adulteration.The performance evaluation metrics are used to analyse the efficiency of these models.The histogram features from the Lab colour space trained on the 1D-CNN model(BS-40 and Epoch 100)show an accuracy of 84.56%.On the other hand,the 2D-CNN model DenseNet-121(AdamW and BS-30)also shows a test accuracy of 84.62%.From the observations of this study,it is concluded that CNN models can be a promising tool for solving the adulteration detection problem in food quality evaluation.Further,internet of things-based systems can be developed to aid the industry and government agencies in monitoring the quality of RCP to harness the unethical practices of food adulteration.

文摘In recent years,the addition of probiotics into non-dairy beverages has gained popularity.Probiotics offer a wider range of options for individuals who are sensitive to dairy products.Incorporating probiotics into widely consumed beverages like carbonated soft drinks poses a notable challenge due to the detrimental impact of acidic pH.Herein,results demonstrate that chitosan-coated alginate/gellan gum microcapsules can enhance the viability of probiotics within carbonated soft drinks.The probiotics,Lactobacillus casei,are encapsulated in microcapsules and exposed to Pepsi,Fanta Strawberry,Sprite,and A&W Root Beer under 4 and 25℃for 60 days and simulated gastrointestinal tract.Microcapsules greatly improve the viability of adding probiotics in different beverages under simulated gastrointestinal tract.The probiotics had a gradual release from microcapsules,reaching maximum release within initial 2 h of simulated intestinal phase.During 4℃storage compared to storage at 25℃,it was found that the number of surviving cells is more than the recommended minimum(10^(6)CFU/g)at the end of the storage.The pH and soluble solids content of beverages containing microcapsules also signify little change.This work shows that the chitosan-coated alginate/gellan microcapsules have the potential to be used as protective microcapsules for probiotics in carbonated soft drinks.

文摘The development of sustainable materials has encouraged the use of biopolymers as alternatives to synthetic polymers.Polymeric films have stood out for their high potential in environmentally sustainable applications.Conventional cellulose acetate(CA)-based films are attractive due to their biodegradability and film-forming ability.However,their functional performance often requires enhancement through the incorporation of additives.In this context,two bio-based additives were investigated:condensed tannin(0%,5%and 10%wt.),a natural polyphenol known for its antioxidant and antimicrobial properties,and nanocrystalline cellulose(CNC)(0%,0.5%and 1%wt.),which act as reinforcing agents to improve mechanical strength and barrier properties.The results showed that tannin generally enhanced mechanical strength and surface uniformity while imparting contact-based antimicrobial activity.CNC reduced water uptake and improved thermal stability,but when used alone,it tended to lower mechanical performance and increase surface roughness.The combination of CNC and tannin produced performance shifts that depended strongly on their relative concentrations,with no consistent synergistic effect across all properties.In certain balanced ratios,CNC benefited fromtannin’smatrix-stabilizing effect,leading to improved strength or reduced moisture absorption.Antimicrobial activity in acetic acid–based films was linked to residual acidity,whereas in acetonebased films,tannin alone was responsible for the antimicrobial effect by contact.These findings highlight that the physicochemical,mechanical,and functional performance of CA films(CAFs)is governed not only by additive type but also by the precise interplay between CNC and tannin,underscoring the need for formulation strategies tailored to the requirements of specific applications.
文摘AIM:To determine the glycemic index(GI),glycemic load(GL)and insulinemic index(Ⅱ)of five starchy foods that are commonly used in Chinese diets.METHODS:Ten healthy subjects aged between 20-30 years were recruited.Each subject was asked to consume 50 g of available carbohydrate portions of test foods and reference food.Finger capillary blood samples were collected at the start of eating and 15,30,45,60,90 and 120 min after consumption.The GI and Ⅱ of foods were calculated from the ratio of incremental area under the glucose/insulin response curves of test and reference foods.The GL for each test food was determined from its GI value and carbohydrate content.RESULTS:The results showed that brown rice elicited the highest postprandial glucose and insulin responses,followed by taro,adlay,yam and mung bean noodles,which produced the lowest.Among the five starchy foods,brown rice evoked the highest GI and GL at 82±0.2 and 18±0.2,followed by taro(69±0.4,12±0.2),adlay(55±0.4,10±0.2),yam(52±0.3,9±0.0)and mung bean noodles(28±0.5,7±0.2),respectively.The Ⅱ values of the test foods corresponded with GI values.Similarly,brown rice gave the highest Ⅱ at 81±0.1,followed by taro(73±0.3),adlay(67±0.3),yam(64±0.5) and mung bean noodles(38±0.3).All five starchy foods had lower GI,GL and Ⅱ than reference bread(P<0.05).CONCLUSION:The GI,GL and Ⅱ values of starchy foods provide important information for the public to manage their diet and could be useful for the prevention of lifestyle-related diseases such as diabetes mellitus.

文摘Green tea has been an important beverage for humans since ancient times, widely consumed and considered to have health benefits by traditional medicine in Asian countries. Green tea phenolic compounds are predominately composed of catechin derivatives, although other compounds such as flavonols and phenolic acids are also present in lower proportion. The bioactivity exerted by these compounds has been associated with reduced risk of severe illnesses such as cancer, cardiovascular and neurodegenerative diseases. Particularly, epigallocatechin gallate has been implicated in alteration mechanisms with protective effect in these diseases as indicated by several studies about the effect of green tea consumption and mechanistic explanation through in vitro and in vivo experiments. The biological activity of green tea phenolic compounds also promotes a protective effect by antioxidant mechanisms in biological and food systems, preventing the oxidative damage by acting over either precursors or reactive species. Extraction of phenolic compounds influences the antioxidant activity and promotes adequate separation from green tea leaves to enhance the yield and/or antioxidant activity. Application of green tea phenolic compounds is of great interest because the antioxidant status of the products is enhanced and provides the product with additional antioxidant activity or reduces the undesirable changes of oxidative reactions while processing or storing food.In this scenario, meat and meat products are greatly influenced by oxidative deterioration and microbial spoilage, leading to reduced shelf life. Green tea extracts rich in phenolic compounds have been applied to increase shelf life with comparable effect to synthetic compounds, commonly used by food industry. Green tea has great importance in general health in technological application, however more studies are necessary to elucidate the impact in pathways related to other diseases and food applications.

文摘Cronobacter sakazakii(C.sakazakii)is a foodborne opportunistic pathogen that can cause life-threatening invasive diseases,such as necrotizing enterocolitis,meningitis,and sepsis in infants.The potential risk of C.sakazakii contamination of powdered infant formula(PIF)is an issue that has attracted considerable attention from manufacturers,regulators,and consumers.C.sakazakii biofilms on the surfaces of equipment and in diverse food-production environments constitute a mode of cell growth that protects the pathogen from hostile environments,and are an important source of persistent contamination of food products.Bacterial biofilms are difficult to remove due to their resistant properties.Conventional cleaning and sterilizing procedures may be insufficient for biofilm control,and may lead to further biofilm development and dispersal.Consequently,novel control strategies are being developed,such as nanotechnology-based delivery systems,interspecies interactions,antimicrobial molecules of microbial origin,natural extracts,and phages.This review focuses on describing the mechanisms underlying the biofilm formation and behavior of C.sakazakii and discussing potential control strategies.

文摘Recently,nanoencapsulation was introduced as an efficient and promising approach for the protection,delivery,and site-specific liberation of the nutraceuticals and bioactive ingredients.Food proteins are attractive materials for developing nanocarriers to protect and deliver bioactives due to their unique functional and biological properties.Food proteins extracted from animals and plants have the ability to form different nanostructures including nanoparticles,hollow particles,nanogels,nanofibrillar aggregates,electrospun nanofibers,nanotubular structures,and nanocomplexes.These nanostructured food proteins have been widely used as nanocarriers for the biologically active compounds and drugs.The release of bioactive compounds from nanocarriers depends mainly on pH as well as swelling and the degradation behavior of nanostructure in the simulated physiological conditions.This review presents the applications of the nanostructured food proteins for the encapsulation of bioactive compounds.The major techniques for the fabrication of nanocarriers are described.The encapsulation,protection,and release of bioactive compounds in different nanostructured food proteins were also discussed.
文摘Presented in several types of food, bioactive amines are described as organic bases of low molecular weight. They have vasoactive, psychoactive and toxicological characteristics and constitute a potential health risk. The concentration of amines formed in foods depends on the type of microorganisms present, the action of decarboxylase enzymes produced by microorganisms on specific amino acids and favorable conditions for enzymatic activity. The presence of these chemical metabolites has been suggested as a quality indicator in routine analyzes for food production and marketing monitoring. The detection of bioactive amines can be performed by chromatographic methods, fluorometric and enzymatic kits. Bioactive amine formation can be prevented mainly through the adoption of good manufacturing practices, but the industry can also use other methods such as temperature control in the production chain, modified atmosphere packaging and food irradiation. This review aims to address the formation of bioactive amines in foods, emphasizing the formation and classification of these metabolites, aspects related to health, acceptable limits, detection methods and control methods used in the industry to ensure food safety and quality. The success of this approach is linked to the importance of bioactive amines as quality indicators, as well as the discussion on the development of methodologies for determining these substances and discussion of acceptable parameters in food.
文摘Nutritional evaluation of complementary food formulations from maize, soybean and peanut fortified with Moringa oleifera leaf powder was carried out. Maize, soybean and peanut were blended in a ratio of 60:30:10 to produce a complementary food, which was then fortified. While the unfortified food product (sample A) served as control, the other three formulations were fortified with 5%, 10% and 15% Moringa leaf powder to give three samples (B, C and D respectively) of fortified food. Nutritional composition determination and feeding trials were then carried out, using two weeks old male albino rats to determine the performance of the food formulations. While the crude protein, crude fibre, and ash contents of the diets increased significantly (p with fortification, with values ranging from 16.04% to 17.59%, 2.25% to 4.42% and 1.40% to 2.50% respectively, crude fat and carbohydrate decreased significantly (p < 0.05), with concomitant decrease in energy, with values ranging from 23.48% to 20.80%, 49.32% to 47.63% and 472.76% to 448.08 kcal/100g respectively in samples A to D. PER values significantly (p < 0.05) improved up to 10% substitution, from 1.77 in unfortified (sample A) to 1.90 in 10% fortified (sample C), but declined at 15% substitution (sample D) to 1.69. Similarly, NPR values increased from 0.71 to 0.76 and 0.68. However, all the PER values including that of Nestle Cerelac (2.04) were lower than, though within the same range, with the value of 2.10 recommended by the Protein Advisory Group (PAG) for complementary foods. Sample C (10% Moringa flour blend) gave the best performance after rat feeding trials.
文摘Chlorine-based sanitizers have seen wide spread use in food sanitation. The reaction of chlorine species with organic matter is a concern for two reasons. Available chlorine can be “used up” by organic compounds resulting in a lower amount of chlorine available for disinfection. Another concern is that some forms of chlorine can react with some organic compounds to form toxic halogenated disinfection byproducts（DBPs）. Many studies have been conducted to evaluate the role of hypochlorous acid（HOCl） and hypochlorite ion（OCl–） in the production of DBPs with a particular interest in the production of trihalomethanes（THMs） and haloacetic acids（HAAs）. Since most of the chlorine reactions are pH dependent, pH is found to have a significant effect on the formation of chlorine DBPs. In many cases, the concentration of THMs decreases and HAAs increases as pH decreases. pH also plays an important role in the determination of the type and amount of DBPs formed, with lower, more acidic, pHs resulting in the formation of less chloroform. This review summarizes the information from the literature on the role of chlorine-based sanitizers as affected by pH in the formation of different types of DBPs. Alternative novel strategies to minimize the formation of DBPs are also discussed.
文摘This study aimed to evaluate the antibacterial activity of flavonoids extracted from two Libyan brown algae namely Cystoseira compressa and Padina pavonica using microwave-assisted extraction method against pathogenic bacteria isolated from meat, meat products, milk and dairy products (Staphylococcus aureus subsp. aureus (5 isolates), Bacillus cereus (3 isolates), Bacillus pumilus (1 isolate), Salmonella enterica subsp. enteric (4 isolates) and Enterohaemor-rhagic Escherichia coli O157 (EHEC O157) (4 isolates)). All of these isolates were muti-drug resistant with high MAR index. The results showed that C. compressa extract exhibited better and stronger antibacterial activities against the seventeen tested isolates with inhibition zones diameter ranged from 14 - 22 mm compared to P. pavonica extract which showed positive effect against 9 isolates with low inhibition zone ranged from 11 - 16.5 mm. Flavonoids extracted from C. compressa also displayed the best spectrum of bactericidal effect with a ratio MBC/MIC ≤ 4 obtained on all susceptible tested bacterial strains. Flavonoids and proanthocyanidins significantly contributed to the antibacterial properties. The mode of action of these active extracts is under investigation.
文摘With the development of technology, several new processing techniques are being introduced for the food industry. By applying those novel techniques to food systems, it has been found that the structural and functional properties of food could be altered. Microfluidization which is also known as high pressure homogenization is one of the novel technologies that could be applied in food industry to obtain many beneficial outcomes. High pressure processing is another novel technique that is mainly playing the microbicidal effect. This work is concerned on the possibility of using microfluidization and high pressure processing in food industry based on the experimental findings. These techniques could be used as useful tools in the field of food science and technology.

文摘In order to improve appetite,attract consumers and even conform to the food culture,food coloring has become one of the necessary links in modern food processing.For example,dried-tofu will be colored by adding artificial food colors(AFCs)such as sunset yellow,cochineal red A or other seasonings like soy sauce.However,the dispute persists about whether AFCs are harmful to health.Some studies indicate AFCs affect children’s intelligence and attention,cause hyperactivity,and allergy when children consumed≥50 mg.In addition,researches showed that chemical soy sauce produces a trace of methylglyoxal(MGO)in the manufacturing process,which is related to diseases such as oxidative stress,diabetes,and cognitive deterioration.Therefore,natural pigments are relatively new and promising strategy for replacing high-risk AFCs.Thus,the objective of this study was to use dried-tofu as a natural colorants coloring screening platform,through the concept of three primary colors to discuss the coloring effects of natural colorants in Taiwan in double–phase(liquid phase to solid phase)food coloring system and assess the effects of MGO on PC12 neuron cellular morphology and cell cycle at the dietary exposure in soy sauce.Our results showed that formula G:R=0.2:0.8 and C:R=0.08:0.92 were coloring by combined natural colorants had the same eye sensory quality acceptance of consumer and had the intention to purchase.Furthermore,the results from the PC12 cell suggested that dietary exposure of methylglyoxal(<50M)in soy sauce did not affect neuron cellular morphology and cell cycle significantly.Overall,Gardenia Yellow,Curcumin,and Radish Red could overcome the application restrictions in multiplephase food coloring system and simultaneously soy sauce as a coloring agent was safety.It showed the possibility of them as food colorants on dried-tofu.
文摘Synthetic color is added to foods to replace natural color lost during processing. It is causes health problems mainly in children that considered Avery venerable group. This study was carried out investigate the effect of using color foods (Color fruit juice for 6 - 12 hr. Tomato ketchup potato chips (TKPC) color sweet and color chocolate at low (15%) and high (30%)) concentration on serum biochemical, WBC (white blood cell)and histopathology of liver and kidney of rats for 13 week. The results indicated that no significant change in body weight gain, serum glucose, HDL and LDL cholesterol. TKPC (30%) showed that significant increase in total cholesterol (TC), triacylglycerol (TG). Low and high concentration of color chocolate and color sweet was exhibited significant increase of TG. The level of ALT and AST was significant increase of rat’s administration color fruit juice (for 12 hr.) and TKPC at 30%. High concentration of color foods and long time administration of color fruit juice showed significant increase in serum creatinine and albumin compared to control group. Both low and high consumed of color foods exhibited significant decrease in liver GSH. High concentration of color foods lead to increase number of WBC as the result to the response of the immune system to the inflammation. Color foods were reveled change in histological structure of liver and kidney. In conclusion, the use synthetic color in various foods has adverse effect on some of biochemical analysis;and the liver and kidney histopathological structure.
