文摘A dietary transition from refined to whole grains would optimize grain processing,reduce food loss and emissions,and increase food nutritional contents.The results of systematical analysis and calculations in our study show that the average processing loss rate of grains including rice,wheat,and maize is approximately 4.1%in China due to the refinement,equivalent to an annual loss of around 13.3 Mt of grains.Furthermore,the refining process significantly reduces the nutritional contents of rice(51.6%),wheat flour(55.4%),and corn products(80.4%)mainly resulting from the removal of dietary fiber,minerals,and vitamins in refined grains.Replacing refined grains with whole grains in diets would lower agricultural carbon emissions by 2.7%,reducing agricultural water use by 4.3%,and saving arable land by 1,972,607 ha.Total environmental footprint could be reduced by 35%to 79%under three proposed scenarios.These findings indicate that shifting toward whole grain-based diets by Chinese consumers could reduce food losses,enhance human health,and improve environmental sustainability.This approach offers a promising strategy for transitioning towards more resilient and sustainable agri-food systems,benefiting human and planetary health.

文摘This study investigates the potential of starch extracted from underutilized agro-industrial resources as non-food-competing raw materials for the development of flexible bioplastics for food packaging applications.Starch was extracted from three biomass sources:rubber cassava(Manihot glaziovii),banana stem,and banana peel from Ambonese banana(Musa acuminata L.).Rubber cassava starch(SRC)exhibited the highest starch yield(50.68±0.28%),significantly surpassing banana stem(SBS,14.20±0.25%)and banana peel(SBP,3.07±0.15%).The amylose contents of SRC,SBS,and SBP were 28.18%,52.80%,and 56.57%,respectively,while their amylopectin contents were 71.83%,47.20%,and 43.43%.FTIR spectra confirmed the absence of cyanogenic groups in SRC,indicating its safety for packaging applications.XRD analysis revealed that PSRC films were predominantly amorphous,while PSBS and PSBP showed higher crystallinity.The enhancement of mechanical properties,specifically PSBS,showed the highest tensile strength at 16.04±0.56 MPa,whereas PSRC demonstrated the highest elongation at break at 23.57±0.40%,which could be attributed to the inherent characteristics of the starch sources.Additionally,PSRC film exhibited the highest transparency at 60.2%,the greatest water solubility at 34.92%,and the lowest water contact angle at 41.58○,confirming its more hydrophilic nature compared to other films.This work highlights the potential of low-cost,sustainable,and non-food agro-industrial starch sources as promising candidates for the development of flexible,eco-friendly bioplastics.

文摘In order to ensure food safety,controlling foodborne pathogen contamination is of utmost importance.Growing apprehensions regarding the safety of synthetic antimicrobials,due to their adverse health effects,have prompted a search for alternative options.Plant natural products(PNPs)with antimicrobial activity are being explored as a viable alternative.Among the various antimicrobial natural products studied,plant essential oils,plant flavonoids,plant polyphenols,plant polysaccharides,and plant antimicrobial peptides have been identified as potential candidates.PNPs demonstrate a diverse array of antimicrobial mechanisms,encompassing cell wall and membrane damage,interference with genetic replication,disruption of energy metabolism,and induction of oxidative stress at the single-cell level,as well as inhibition of biofilm formation and quorum sensing at the population level.Certain PNPs have been harnessed as natural antimicrobial agents for the food preservation.The utilization of encapsulation technology proves to be an effective strategy in protecting PNPs,thereby ensuring good antimicrobial efficacy,enhanced dispersibility,and controlled release within food products.The utilization of nanoemulsions,nanoliposomes,edible packaging,electrospun nanofibers,and microcapsules formed by encapsulation has enriched the ways in which PNPs can be applied in food preservation.Although PNPs have great potential in food preservation,their widespread application in the food industry is currently constrained by factors such as production costs,safety concerns,and legal considerations.Chemical synthesis and biosynthesis pathways offer viable strategies for reducing the cost of producing PNPs,and ongoing efforts to assess safety and improve regulatory frameworks are likely to facilitate the broader adoption of PNPs in food preservation practices.This article provides an overview of the main types of PNPs with antimicrobial activity and their properties,focusing on their mechanisms of action.Additionally,it summarizes the use of PNPs in food preservation and discusses the characteristics and applications of different encapsulation technologies.Lastly,the paper briefly analyzes current limitations and proposes potential future trends for this field.
文摘Food safety,specifically in restaurants,is becoming a key public health priority because of the increased number of meals eaten outside the home.Foodborne illness prevention thus is a significant concern and a public health priority in the United Arab Emirates,particularly Dubai,because of the extensive tourism industry.The purpose of the study was to evaluate the effectiveness of using demonstrations in training sessions to improve food safety knowledge and practices amongst food handlers.A descriptive and quantitative approach has been applied to collect the quantifiable information related to the research study.This has been further analyzed using the correlation tests to gather the required data.On comparison of the pre-test scores between the intervention and the control group,the t-test analysis showed significant difference in the level of food safety knowledge between the two groups.Pre-test score for the control group was 78.33 and post-test score was 104.66.In the case of the intervention group,pre-test score was 91.37 and post-test score was 130.75.The scores of food handlers’food safety practice for control group:pre-treatment score was 470 and post-treatment score was 646.For intervention group:pre-test score was 723 and post-test score was 1,056.The study concluded that training with demonstration techniques is an effective way of improving compliance with food safety guidelines.It has been understood that training helps in improving the performance of the employees while reducing the foodborne diseases and maintaining hygiene in the food.The study recommends every restaurant needs to provide regular trainings to the employees so that the restaurants can maintain hygiene and food safety practices.

文摘Cadmium accumulation in seafood has become a major concern for human health.Recently,there has been an increasing focus on the potential risks associated with food-borne fluorescent carbon dots(CDs)that are formed during the thermal processing of seafood.The co-occurrence of cadmium and CDs from cooked seafood become a common phenomenon and co-exposure of them to human has been an inevitable route during long-term seafood consuming.In addition,it has been widely recognized that CDs can be used as nanocarriers for metal ion chelation for their transport into organisms,thereby,they could influence the bioavailability of metal ion.While there have been numerous studies on the toxic effects of cadmium or CDs,none have explored the combined toxicity of food-borne CDs from clams(CCDs)and Cd^(2+).In this study,we investigated the single or co-exposure(combined exposure)of Cd^(2+)and CCDs on PC12 cells to investigate the combined toxicity of them.Our analysis of cell viability revealed that CCDs significantly augmented the cytotoxicity induced by Cd^(2+).More in-depth metabolomics and lipidomics investigation indicated that the combined exposure of Cd^(2+)and CCDs led to significant metabolic disorders,causing an antagonistic effect on energy metabolism,and a synergistic effect on amino acids and lipids metabolism.The disturbance in metabolomics and lipidomics was further supported by the disruption of mitochondrial membrane potential and the accumulation of reactive oxygen species following co-exposure.These findings provide new evidence that support the enhanced cytotoxicity of Cd^(2+)by the CCDs derived from the thermal processing of clams.This study also declares the necessary that prioritize the investigation of the potential impact of other thermal processing hazards originating from heat-processed foods on the toxicity of heavy metal ions.

文摘Food allergy has become a global concern.Spleen tyrosine kinase(SYK)inhibitors are promising therapeutics against allergic disorders.In this study,a total of 300 natural phenolic compounds were firstly subjected to virtual screening.Sesamin and its metabolites,sesamin monocatechol(SC-1)and sesamin dicatechol(SC-2),were identified as potential SYK inhibitors,showing high binding affinity and inhibition efficiency towards SYK.Compared with R406(a traditional SYK inhibitor),sesamin,SC-1,and SC-2 had lower binding energy and inhibition constant(Ki)during molecular docking,exhibited higher bioavailability,safety,metabolism/clearance rate,and distribution uniformity ADMET predictions,and showed high stability in occupying the ATP-binding pocket of SYK during molecular dynamics simulations.In anti-dinitrophenyl-immunoglobulin E(Anti-DNP-Ig E)/dinitrophenyl-human serum albumin(DNP-HSA)-stimulated rat basophilic leukemia(RBL-2H3)cells,sesamin in the concentration range of 5-80μmol/L influenced significantly the degranulation and cytokine release,with 54.00%inhibition againstβ-hexosaminidase release and 58.45%decrease in histamine.In BALB/c mice,sesamin could ameliorate Anti-DNP-Ig E/DNP-HSA-induced passive cutaneous anaphylaxis(PCA)and ovalbumin(OVA)-induced active systemic anaphylaxis(ASA)reactions,reduce the levels of allergic mediators(immunoglobulins and pro-inflammatory cytokines),partially correct the imbalance of T helper(Th)cells differentiation in the spleen,and inhibit the phosphorylation of SYK and its downstream signaling proteins,including p38 mitogen-activated protein kinases(p38 MAPK),extracellular signalregulated kinases(ERK),and p65 nuclear factor-κB(p65 NF-κB)in the spleen.Thus,sesamin may be a safe and versatile SYK inhibitor that can alleviate Ig E-mediated food allergies.
