Arrangement of starch content from most to least is: rice>sweet potato>potato

1, rice starch content: 70%-80%.

2, sweet potato starch content, the general tuber starch content of the fresh weight of 15-26%, high can reach 30%.

3, fresh potatoes contain 9-20% starch.

The starch content of all types of plants are high, rice contains 62% to 86% starch, wheat contains 57% to 75% starch, corn contains 65% to 72% starch, potato contains less than 20% starch. Partial hydrolysis of branched-chain starch can produce a mixture called dextrin. Dextrin is mainly used as food additives, glue, paste, and used in the manufacture of paper and textiles (finishing) and so on.

Extended information

1, starch is a nutrient stored in the plant body, stored in the seeds and tubers, is an important part of the food, chewing rice, etc. feel some sweetness, this is because of saliva in the saliva of the salivary amylase enzyme will be hydrolyzed starch into a disaccharide - maltose.

2, food into the small intestine, but also by the pancreas secretion of salivary amylase and intestinal fluid hydrolysis, the formation of glucose (monosaccharide) is absorbed by the small intestinal villi, the body's tissues and organs of nutrients.
