According to the World Health Organisation, PEM accounts for 49% of the 10.4 million deaths of children under five that take place in developing countries. The aim of this study was to evaluate the influence of gum Arabic (GA) and texturized soy protein (TSP) and their interactive effect on proximate, functional, and textural properties of the protein-rich snack stick produced from ground green maize, GA powder, and ground TSP. GA varied at 0%, 4%, 8%, and 12%, while TSP varied at 0%, 12%, 24% and 36%. The 5 cm long protein-rich snack sticks were made using a sausage stuffer and baked in an oven at 110˚C for 1 hr 30 minutes. The snack sticks were subjected to proximate, functional and textural analysis using the standard methods. Increasing GA resulted in a significant (p p < 0.05) increased the protein content (32.46%), Ash content (3.6%), fat (11.96%), and moisture content (16.25%) of protein-rich snack sticks. The interactive effect between GA and TSP led to a decrease in fibre and carbohydrates. Results from this study show GA and TSP significantly enhanced the physico-chemical properties of protein-rich snack sticks. A sample with 4% GA and 36% TSP is recommended for the best physico-chemical attributes of the protein-rich snack stick.展开更多

The drying methods were air drying （AD）, freeze drying （FD）, freeze drying followed by microwave vacuum drying （FD＋MVD） and air drying followed by explosion puffing drying （AD＋EPD）. Overall, FD＋MVD can be used as a suitable drying method for the development of probiotic enriched apple snacks in consideration of colour, texture, sensory quality, bacterial viability and storage stability. Probiotic bacteria in FD＋MVD-dried samples remained above 1×106 CFU g 1 for 120 days at 25℃C. Interestingly, bacterial viability in FD＋MVD-dried samples turned out to be significantly higher than FD-dried samples during storage for 120 days.展开更多

The benefits include increased protein and starch digestibility in protein-enriched cereal snack products. Extrusion cooking needs to be controlled if product quality is to be maintained. Extrusion cooking was carried out at barrel temperature of 110°C - 150°C, screw speed of 350 - 450 rpm, and feed moisture of 12% - 14% to investigate the effect of extrusion conditions on physical properties (expansion ratio and bulk density) of a rice, sorghum and soy flour blend. From response surface analysis, expansion ratio and bulk density were found to be significantly (P < 0.05) dependent on feed moisture and barrel temperature while the screw speed had a significant (P > 0.05) effect. Expansion ratio and bulk density ranged from 2.0 to 2.6 and 0.79 to 0.95 g/ml respectively. One hundred grams of the extruded product would supply 45% of the recommended daily allowance for protein in children aged up to 12 years. The mineral content in 100 g extrudates was found to be 52 mg calcium, 3.01 mg iron and 1.23 mg zinc. The retention of amino acids in the extruded products was 88% - 95% with lysine—a limiting amino acid in cereals having a loss of 9.1% after extrusion. Extrusion conditions can be optimized to produce ready-to-eat snack products with high expansion ratio, low bulk density and a good nutritional profile to meet the growing consumer needs for nutritious ready-to-eat snack products.展开更多

Among important biochemical components for sorghum processing are levels of starch and starch depolymerizing enzymes. Due to presence of high amount of starch （56%-73%）, sorghum could be the good candidate for manufacturing of expanded snacks. The effect of various extrusion process parameters on structural and functional properties of extruded snacks prepared using three selected varieties of sorghum including SPV 1411 （Parbhani moti） and SPV 1595 （Parbhani jyoti） （newly developed varieties） and M-35-1 （Maldandi） were investigated in this study. Sorghum flour of different particle size viz. 2, 0.84 and 0.49 mm, was subjected to different extrusion processing conditions： feed moisture content （16%-24%）, die temperature （110-150 ~C）, screw speed （150-270 rpm） and feed rate （50-120 g min^-1）. The feed moisture and die temperature （process variables） showed significant effect on the physical properties. This process parameter also increased dietary fibre with decrease in the content of tannins. Box-behnken design was successfully used to show a relationship between extrusion processing conditions and physical properties of extrudates. The extrudates obtained using SPV 141 l, a variety of sorghum, showed significant results in all attributes compared to SPV 1595 and M-35-1, at feed moisture 22%, die temperature 130℃ and screw speed 210 rpm with 90% overall acceptability.展开更多

Blueberry as the raw material, the microwave power, initial moisture content, puffing time and mass were employed as experimental factors. The pressure, temperature, amount of water vapor and puffing properties in terms of the volume, hardness and brittleness were employed as target parameters. The higher microwave intensity and initial moisture content resulted in the more amount of water vapor in the snacks and more holes in the appropriate puffing time. The shape and structure of the snacks tended to be stable with the removal of moisture.展开更多

In this paper, we analyzed the association of frequency of nighttime snacking with obesity, hyperlipidemia and hyperglycemia using a Chinese teacher cohort. The Chinese teacher study contains 22,176 of the general adult population operated on in 2015.Information of nighttime snacking frequency was acquired by questionnaire. Overweight and obesity outcome were assessed by body mass index（BMI）, and hypertension; hyperlipidemia and hyperglycemia were self-reported.Associations between nighttime snacking consumption and outcomes were performed with multivariat regression and further stratification analyses. We found a significant association（OR 2.11, 95% CI 1.24, 3.62; P for trend 〈0.001）between most frequent nighttime snacking and hyperglycemia. A remarkable association was also observed between most frequent consumption of nighttime snack and obesity（OR 3.10, 95% CI 1.63, 5.89; P for trend〈0.001）. The present results provide epidemiological evidence that consumption of nighttime snack was associated with obesity and hyperglycemia in Chinese adult teachers. However, the underlying mechanisms still need further investigation.展开更多

To improve snacks’ nutritional quality, CSM and corn flour were extruded using a simple screw extruder. An expansion index (EI) ranging of 1.2 - 4.7 was obtained. Penetration force (PF) was 7 - 9 times harder than other extruded products. High extrusion temperature and high CSM concentrations decreased (p p p< 0.05) extrudates’ water solubility index. Extrusion conditions used showed a 68.5% starch gelatinization, and a starch availability of more than 97%, which explains the high expansion index obtained.展开更多

An anonymous self-report questionnaire was administered to 1936 students (13 - 15 years old) in eight junior high schools in Tokyo, Japan. The students responded to the Snack Choice Questionnaire (SCQ) as well as questions concerning snacking behaviors, lifestyles, and demographics. Cluster analysis was applied to sort the sample according to SCQ scores. Each cluster’s characteristics were examined by gender using the χ2 test or the Kruskal-Wallis test with a Bonferroni adjustment. Participants were divided into four groups: high in all factors, low in all factors, low value in health, and value in health. The “value in health” group was composed of more girls than boys and the “low in all factors” group had fewer girls than boys. Those in the “high in all factors” and “low value in health” groups indicated that they consumed more snacks. Moreover, gender differences were revealed. By assessing the SCQ prior to providing nutrition education, we can obtain valuable information to make nutrition education planning.展开更多

The survey was carried out during 2008 to 2009 in 3 selected governorates (Al-Hassa, Al- Katif and AD-Dammam) localized in the eastern area of Saudi Arabia. The age of study participants (298) was ranged between less than 4 – over 30 years. The snacks and drinks consumption data were gathered and calculated using the frequency methods. Forty nine samples of snacks and beverages were analyzed by High Performance Liquid Chromatography (HPLC) for glutamate and caffeine contents. The results indicated that total intake of snacks, chocolates and drinks were significantly correlated (spearman r = 0.856, 0.591, 0.943, p = 0.0) with total intake of glutamate and caffeine. The mean of caffeine intake was 40.4± 44.5 mg, while the mean of glutamate intake was 0.134± 0.146 mg. The highest concentration of glutamate was in Pringles with Ketchup (0.420), Bugles Smoking BBQ (0.660) and Indomie with Vegetables (0.860). The high caffeine concentrations of Kit Kat, Ulker and Galaxy samples were 166, 165.5, and 134.5 mg/kg respectively, while the beverages, the high caffeine concentrations were presented in energy drinks like Red bull (345.5), Power Horse (339.0) and Bugzy(333.0) mg/L. The children aged between 4– 8 were the most consumers of snacks which containing glutamate, while the adolescents consumed more chocolates and beverages which containing caffeine. These finding suggests that consumption of salty snacks, and sugar-sweetened beverages is mounting between important categories in the community, so interventions focusing on increasing physical activity and fruit and vegetable consumption will have an impact on obesity control and promoting health.展开更多

During morning break 14 girls and 11 boys were provided with 160 ml of semi-skimmed milk or153 gof apple in a randomised crossover manner. Visual analogue scales were used to record hunger, prospective food consumption and fullness, immediately before and after breakfast, immediately before and after the mid-morning snack, and every 60 min until 21:00 on each day. School dinner/packed lunch energy intakes were assessed 90 min following the mid-morning snacks, in addition to evening energy intake. Children felt less hungry and could eat less when apple was consumed, however lunch and evening energy intakes were not different. Fluctuations in appetite did not translate into differences in energy intake therefore both milk and fruit should be promoted as mid-morning snacks in primary schools.展开更多

It was hypothesized that snacks produced by extrusion would be more healthful than their raw formulations. Bile acid binding has been reported to indicate cholesterol lowering and cancer risk reduction potential of food and fractions. Bile acid binding potential of five lentil snack raw formulations and their extruded snacks were evaluated. The raw formulations were 100% lentils (F01), 69% lentils (F02), 57% lentils + 12% supplement (F03), F03 with 125 μg/100g Chromium (F04), F03 with 536 μg/100g Chromium (F05), and their respective extruded (E) snacks E01, E02, E03, E04 and E05. The in vitro bile acid binding on an equal dry matter basis relative to cholestyramine, was F01 (0.5%), E01 (3.7%), F02 (0.6%), E02 (3.0%), F03 (1.6%), E03 (5.1%), F04 (2.0%), E04 (4.2%), F05 (0.8%) and E05 (3.6%). Replacing 12% lentils with high protein supplements (F02 vs. F03) resulted in significantly higher bile acid binding, suggesting that the supplement appears to have higher bile acid binding capacity than that of lentils. All the extruded lentil snacks had significantly higher bile acid binding compared with their raw formulations. Extruding with added chromium containing yeast resulted in significantly lower bile acid binding in a dose dependent manner. Most healthful lentil snacks were produced with the addition of high protein supplement without added chromium-containing yeast (E03). Data proved the hypothesis that lentil snacks produced by extrusion are significantly more healthful than their raw formulations.展开更多

TFA levels when not available in food composition tables make it difficult to estimate dietary intake. With the aim to analyze and identify the actual amount of trans fatty acid present in selected Indian fast food items, triplicate samples of six commonly consumed snacks as well as the oil used for preparing the same were collected from three different places. The separation of fatty acid was done using gas chromatography. Trans fatty acid isomers of oleic acid, linoleic acid and linolenic acid were identified in all food items. The predominant trans fatty acid present in all the food items was elaidic acid (18:1t9). The total trans fatty acids in different food items ranged from almost negligible to as high as 14.58 g/100g food. Different amount of TFA was found in same food category sourced from different outlets which is a challenge in making regulations aimed at TFA reduction so as to decrease health risk.展开更多

Eight samples (four spicy and four salty) of most commonly consumed deep-fried snacks in India, viz., murukku (an extruded strands-like product made from the mixture of rice flour and black gram dhal flour) were analyzed for moisture, oil content, CIE instrumental color (L*a*b*), instrumental texture measurement (breaking strength of murukku strands), aroma finger printing by electronic nose and sensory quality. Quantitative descriptive analysis (QDA) and results showed that sample ‘A’ had highest acceptance and sample D lowest acceptance scores. The results indicated that significant variations were observed in moisture content (2.21 - 3.35%), oil content (30.10 - 34.61%) and textural parameters. Electronic nose technique was found useful in fingerprinting the aroma pattern of market samples in a short time. Descriptive sensory profiling coupled with principal component analysis showed the interrelationship among and between sensory, instrumental, chemical parameters.展开更多

Extrusion cooking was carried out at barrel temperature of 110°C - 150°C, screw speed of 350 - 450 rpm, and feed moisture of 12% - 14% to investigate the effect of extrusion conditions on physical properties (expansion ratio and bulk density) of a rice, sorghum and soy flour blend. From response surface analysis, expansion ratio and bulk density were found to be significantly (P < 0.05) dependent on feed moisture and barrel temperature while the screw speed had a significant (P > 0.05) effect. Expansion ratio and bulk density ranged from 2.0 to 2.6 and 0.79 to 0.95 g/ml respectively. One hundred grams of the extruded product would supply 45% of the recommended daily allowance for protein in children aged up to 12 years. The mineral content in 100 g extrudates was found to be 52 mg calcium, 3.01 mg iron and 1.23 mg zinc. The retention of amino acids in the extruded products was 88% - 95% with lysine—a limiting amino acid in cereals having a loss of 9.1% after extrusion. Extrusion conditions can be optimized to produce ready-to-eat snack products with high expansion ratio, low bulk density and a good nutritional profile to meet the growing consumer needs for nutritious ready-to-eat snack products.
文摘Sorghum is a staple food grain in many semi-arid and tropic areas of the world, because of its good adaptation to hard environments and its good yield of production. Among important biochemical components for sorghum processing are levels of starch and starch depolymerizing enzymes. Due to presence of high amount of starch （56%-73%）, sorghum could be the good candidate for manufacturing of expanded snacks. The effect of various extrusion process parameters on structural and functional properties of extruded snacks prepared using three selected varieties of sorghum including SPV 1411 （Parbhani moti） and SPV 1595 （Parbhani jyoti） （newly developed varieties） and M-35-1 （Maldandi） were investigated in this study. Sorghum flour of different particle size viz. 2, 0.84 and 0.49 mm, was subjected to different extrusion processing conditions： feed moisture content （16%-24%）, die temperature （110-150 ~C）, screw speed （150-270 rpm） and feed rate （50-120 g min^-1）. The feed moisture and die temperature （process variables） showed significant effect on the physical properties. This process parameter also increased dietary fibre with decrease in the content of tannins. Box-behnken design was successfully used to show a relationship between extrusion processing conditions and physical properties of extrudates. The extrudates obtained using SPV 141 l, a variety of sorghum, showed significant results in all attributes compared to SPV 1595 and M-35-1, at feed moisture 22%, die temperature 130℃ and screw speed 210 rpm with 90% overall acceptability.

文摘In order to reveal the mechanism of microwave puffing berry snack, a center combination experiment method was employed to explore the puffing process of blueberry snacks. Blueberry as the raw material, the microwave power, initial moisture content, puffing time and mass were employed as experimental factors. The pressure, temperature, amount of water vapor and puffing properties in terms of the volume, hardness and brittleness were employed as target parameters. The higher microwave intensity and initial moisture content resulted in the more amount of water vapor in the snacks and more holes in the appropriate puffing time. The shape and structure of the snacks tended to be stable with the removal of moisture.

文摘Relationship between nighttime snack and human health conditions remains unclear. In this paper, we analyzed the association of frequency of nighttime snacking with obesity, hyperlipidemia and hyperglycemia using a Chinese teacher cohort. The Chinese teacher study contains 22,176 of the general adult population operated on in 2015.Information of nighttime snacking frequency was acquired by questionnaire. Overweight and obesity outcome were assessed by body mass index（BMI）, and hypertension; hyperlipidemia and hyperglycemia were self-reported.Associations between nighttime snacking consumption and outcomes were performed with multivariat regression and further stratification analyses. We found a significant association（OR 2.11, 95% CI 1.24, 3.62; P for trend 〈0.001）between most frequent nighttime snacking and hyperglycemia. A remarkable association was also observed between most frequent consumption of nighttime snack and obesity（OR 3.10, 95% CI 1.63, 5.89; P for trend〈0.001）. The present results provide epidemiological evidence that consumption of nighttime snack was associated with obesity and hyperglycemia in Chinese adult teachers. However, the underlying mechanisms still need further investigation.
文摘The results of the present study indicate that glandless cottonseed meal (CSM) can be incorporated in extruded corn flour snacks at a 10% content level, which increases snack protein content to 12.8% and reduce fat content to 6.2%. To improve snacks’ nutritional quality, CSM and corn flour were extruded using a simple screw extruder. An expansion index (EI) ranging of 1.2 - 4.7 was obtained. Penetration force (PF) was 7 - 9 times harder than other extruded products. High extrusion temperature and high CSM concentrations decreased (p p p< 0.05) extrudates’ water solubility index. Extrusion conditions used showed a 68.5% starch gelatinization, and a starch availability of more than 97%, which explains the high expansion index obtained.
文摘The aims of the present study were to group junior high school students according to factors influencing their snack choice and identify differences between the characteristics and snack choice behaviors of the groups. An anonymous self-report questionnaire was administered to 1936 students (13 - 15 years old) in eight junior high schools in Tokyo, Japan. The students responded to the Snack Choice Questionnaire (SCQ) as well as questions concerning snacking behaviors, lifestyles, and demographics. Cluster analysis was applied to sort the sample according to SCQ scores. Each cluster’s characteristics were examined by gender using the χ2 test or the Kruskal-Wallis test with a Bonferroni adjustment. Participants were divided into four groups: high in all factors, low in all factors, low value in health, and value in health. The “value in health” group was composed of more girls than boys and the “low in all factors” group had fewer girls than boys. Those in the “high in all factors” and “low value in health” groups indicated that they consumed more snacks. Moreover, gender differences were revealed. By assessing the SCQ prior to providing nutrition education, we can obtain valuable information to make nutrition education planning.
文摘The aim of this study was to estimate the intake level of glutamate and caffeine from some snacks and drinks. The survey was carried out during 2008 to 2009 in 3 selected governorates (Al-Hassa, Al- Katif and AD-Dammam) localized in the eastern area of Saudi Arabia. The age of study participants (298) was ranged between less than 4 – over 30 years. The snacks and drinks consumption data were gathered and calculated using the frequency methods. Forty nine samples of snacks and beverages were analyzed by High Performance Liquid Chromatography (HPLC) for glutamate and caffeine contents. The results indicated that total intake of snacks, chocolates and drinks were significantly correlated (spearman r = 0.856, 0.591, 0.943, p = 0.0) with total intake of glutamate and caffeine. The mean of caffeine intake was 40.4± 44.5 mg, while the mean of glutamate intake was 0.134± 0.146 mg. The highest concentration of glutamate was in Pringles with Ketchup (0.420), Bugles Smoking BBQ (0.660) and Indomie with Vegetables (0.860). The high caffeine concentrations of Kit Kat, Ulker and Galaxy samples were 166, 165.5, and 134.5 mg/kg respectively, while the beverages, the high caffeine concentrations were presented in energy drinks like Red bull (345.5), Power Horse (339.0) and Bugzy(333.0) mg/L. The children aged between 4– 8 were the most consumers of snacks which containing glutamate, while the adolescents consumed more chocolates and beverages which containing caffeine. These finding suggests that consumption of salty snacks, and sugar-sweetened beverages is mounting between important categories in the community, so interventions focusing on increasing physical activity and fruit and vegetable consumption will have an impact on obesity control and promoting health.
文摘The purpose of this research was to inform primary school nutritional policy by identifying which mid-morning snack would be more beneficial to consume from an appetite control perspective. During morning break 14 girls and 11 boys were provided with 160 ml of semi-skimmed milk or153 gof apple in a randomised crossover manner. Visual analogue scales were used to record hunger, prospective food consumption and fullness, immediately before and after breakfast, immediately before and after the mid-morning snack, and every 60 min until 21:00 on each day. School dinner/packed lunch energy intakes were assessed 90 min following the mid-morning snacks, in addition to evening energy intake. Children felt less hungry and could eat less when apple was consumed, however lunch and evening energy intakes were not different. Fluctuations in appetite did not translate into differences in energy intake therefore both milk and fruit should be promoted as mid-morning snacks in primary schools.
文摘Fortification of apple slices with t-resveratrol glucoside was obtained by vacuum impregnation (VI) of apple slices with a solution containing grape juice using response surface methodology (RSM). Three independent variables of the VI process: vacuum pressure, application time and relaxation time, were coded at five levels in a central composite design. The VI-treated and dried apple slices were analyzed for t-resveratrol glucoside concentration and textural attributes (gradient and linear distance). Multiple response optimization revealed the following optimum VI condi-tions for the bioactive enrichment and improved textural quality of dried apple slices: vacuum pressure of 6 in. of Hg, application time of 10 min, and relaxation time of 22.5 min.
文摘Previously we have reported that extrusion significantly improved healthful potential of cereals. It was hypothesized that snacks produced by extrusion would be more healthful than their raw formulations. Bile acid binding has been reported to indicate cholesterol lowering and cancer risk reduction potential of food and fractions. Bile acid binding potential of five lentil snack raw formulations and their extruded snacks were evaluated. The raw formulations were 100% lentils (F01), 69% lentils (F02), 57% lentils + 12% supplement (F03), F03 with 125 μg/100g Chromium (F04), F03 with 536 μg/100g Chromium (F05), and their respective extruded (E) snacks E01, E02, E03, E04 and E05. The in vitro bile acid binding on an equal dry matter basis relative to cholestyramine, was F01 (0.5%), E01 (3.7%), F02 (0.6%), E02 (3.0%), F03 (1.6%), E03 (5.1%), F04 (2.0%), E04 (4.2%), F05 (0.8%) and E05 (3.6%). Replacing 12% lentils with high protein supplements (F02 vs. F03) resulted in significantly higher bile acid binding, suggesting that the supplement appears to have higher bile acid binding capacity than that of lentils. All the extruded lentil snacks had significantly higher bile acid binding compared with their raw formulations. Extruding with added chromium containing yeast resulted in significantly lower bile acid binding in a dose dependent manner. Most healthful lentil snacks were produced with the addition of high protein supplement without added chromium-containing yeast (E03). Data proved the hypothesis that lentil snacks produced by extrusion are significantly more healthful than their raw formulations.
文摘Trans fatty acids have adverse effects on health, so knowledge of their contents in foods would enable people to make informed food choices. TFA levels when not available in food composition tables make it difficult to estimate dietary intake. With the aim to analyze and identify the actual amount of trans fatty acid present in selected Indian fast food items, triplicate samples of six commonly consumed snacks as well as the oil used for preparing the same were collected from three different places. The separation of fatty acid was done using gas chromatography. Trans fatty acid isomers of oleic acid, linoleic acid and linolenic acid were identified in all food items. The predominant trans fatty acid present in all the food items was elaidic acid (18:1t9). The total trans fatty acids in different food items ranged from almost negligible to as high as 14.58 g/100g food. Different amount of TFA was found in same food category sourced from different outlets which is a challenge in making regulations aimed at TFA reduction so as to decrease health risk.
文摘A study was carried out to examine the quality parameters of commercially available popular deep-fried snack-Mu- rukku. Eight samples (four spicy and four salty) of most commonly consumed deep-fried snacks in India, viz., murukku (an extruded strands-like product made from the mixture of rice flour and black gram dhal flour) were analyzed for moisture, oil content, CIE instrumental color (L*a*b*), instrumental texture measurement (breaking strength of murukku strands), aroma finger printing by electronic nose and sensory quality. Quantitative descriptive analysis (QDA) and results showed that sample ‘A’ had highest acceptance and sample D lowest acceptance scores. The results indicated that significant variations were observed in moisture content (2.21 - 3.35%), oil content (30.10 - 34.61%) and textural parameters. Electronic nose technique was found useful in fingerprinting the aroma pattern of market samples in a short time. Descriptive sensory profiling coupled with principal component analysis showed the interrelationship among and between sensory, instrumental, chemical parameters.
