Cassava starch is modified to increase porosity and lacerations that are limited when only enzymatic treatments used. This study proposes improve activity of α-amylase amyloglucosidase on the polymer chains cassava by implementing physical thermal pretreatments below gelatinization temperature before hydrolytic process. The increased biocatalytic action enzymes, causing significant changes in m...

BACKGROUND Starch is the major component of potato tubers, amounting approximately to 150-200 g kg (-1) of the tuber weight. Starch is considered to be a major factor for the functionality of the potato in food applications. This study evaluated the physical characteristics of potato starches isolated from tubers of different potato cultivars grown in soil with three levels of phosphorus (P) av...

a study has been made of the compaction properties of two experimental starches, namely yam starch obtained from dioscorea rotundata and rice starch obtained from oryza sativa and the mechanical properties of their tablets, in comparison with those of official corn starch. the influences of the physical and geometric properties of the starch particles on the compression properties of the starch...

ACAC), and fatty acid synthetase (FAS) were studied in male Wistar rats after a period of starvation and refeeding of diets containing 400 g glucose, or raw or cooked starches as the source of carbohydrate/kg. Starches fed included maize, potato, wheat, rice, and tapioca. 2. When compared to the responses of rats given the glucose-containing diet, rats given raw maize-or rice-starch-containing ...

Starches were isolated from cassava, cocoyam and breadfruit by wet milling process. The physicochemical, functional and pasting characteristics of the isolated starches were then examined and compared. Moisture and fat contents varied between 4.91 – 12.94% and 0.90 – 2.20% respectively. Bulk density and pH ranged between 0.64 – 0.68 and 5.53 – 6.15, respectively. Cassava and breadfruit starches...
