Food grade resistant starches (RS) were prepared from 11 starches by reacting starch with a mixture of sodium trimetaphosphate and sodium tripolyphosphate in aqueous alkaline slurry. The products belong to RS4 and contain up to 100% RS when assayed with the total dietary fiber method 991.43 of the Association of Official Analytical Chemists. The RS4 starches showed low swelling power (3g/g) after gelatinization in excess water. Reversibly swellable distarch phosphates with medium swelling power (4-12g/g) were also prepared by pre-swelling of starch in aqueous alkaline solution with salt, cross-linking, purifying and gelatinizing in hot water (95°C). After 6 cycles of swelling in hot water and oven drying, a medium swelling starch made from wheat lost negligible mass and maintained granule integrity. Hamsters fed 10% of low swelling RS4 wheat starch compared to same level of cellulose in their diet showed 1) lower feed consumption, 2) lower weight gain, 3) higher...
Здравствуйте, нам выставили оценки за курсовые за обе курсовые нам поставили 4 при защите, ей видимо в курсовой просто не понравилось негативное отношение к оценщикам, поэтому она и поставила такие оценки, а в переделанной работе это все было убрано и она поставила более высокие оценки, а по банковскому делу поставили 5. Так что все хорошо. Спасибо большое!
