Damaged starch determined by a-amylase hydrolysis to characterize and quantify the molecular composition of cereal foods starches treated with different conditions during processing that had been physically damaged to different extents, by preparation and processing provide the physicochemical data to understand more fully the effects of mechanical damage on amylase, amylopectin content and differential scanning calorimetric （DSC） for selected cereal foods products. There were significant difference between treatments in term of damaged starch content of cereal foods flours which were 0.64% to 36.40%, while the DSC results for the starches were the gelatinisation onset （To）, peak temperature （Tp） and conclusion temperature （To）, and temperatures of selected food starches ranged from 34.86 ℃ to 75.20 ℃, 54.04 ℃ to 85.94 ℃, and 63.5 ℃ to 95.16 ℃. There were significant differences between all cereal foods starches in term of amylose and its contents ranged from 70.3% to 87% and also there were significant differences between the amylopectin content of cereal foods flours ranged from 13.3% to 29.6%.展开更多

However, its nutritional aspect is also a matter of concern. The objective of the present study was hence to assess the nutrient components of fast food sold in streets of Patna town. A total of 30 fast food samples from streets were collected from different locations of Patna town in aseptic containers and immediately transferred to the laboratory for proximate analysis. Descriptive statistics was used to analyze the collected data. In terms of nutrient contribution, the highest energy content was found in Hot potato chips （536 ~ 85.2 kcal /I00 g） followed by Chicken chawmin （527 ~ 253.08 kcal/plat）, Chilli chicken （464 ~ 91.8 kcal/plat） and Pav bhaji （425 -4- 164 kcal/plat）. Highest level of protein was detected in Chilli chicken at 27.3 ~ 5.01 g per serving. Protein of Chilli chicken supplied approximately 29% of the total energy content per serving. Maximum amount of fat was also found in Chilli ckicken （35.5 ~ 31.89 g/plat）. Total fat contribution of Chilli ckicken to the total energy per serving found to be approximately 67%. Highest level of carbohydrate was detected in Idli at 15.0 ~ 9.18 g per serving of sample which contributed approximately 91% of the total energy content per serving. From this study it was concluded that street fast foods provide an appreciable amount of recommended nutrient composition. It could be observed in this study that street fast foods supply appreciable amount of nutrients and calories to the people of Patna.展开更多
