Yes, noodles are actually what we usually call starch, but they have different names.
According to the definition, starch refers to the general name of a class of crop extracts. Due to the different raw materials used, starch is divided into: corn starch, cassava starch, potato starch, sweet potato starch, etc., which is a kind of purity comparison High material.
The main component of noodles is starch, but due to different uses, a small amount of other substances can be added, such as modified starch.
In the northern part of my country, noodles generally refer to sweet potato starch.
Extended information:
Starch is a polymerized form of glucose molecules. It is the most common storage form of carbohydrates in cells. ?
Starch is also called corn starch in the catering industry. The general formula is (C6H10O5)n. When hydrolyzed to the disaccharide stage, it becomes maltose. The chemical formula is C12H22O11. After complete hydrolysis, it obtains monosaccharide (glucose). The chemical formula is C6H12O6 ?.
There are two types of starch: amylose and amylopectin.
The former is an unbranched helical structure; the latter is composed of 24 to 30 glucose residues connected end to end by α-1,4-glycosidic bonds, with α-1,6- Glycosidic bond. Amylose turns blue when exposed to iodine, and amylopectin turns purple when exposed to iodine.
This is not a chemical reaction or interaction between starch and iodine, but the hole in the center of the starch spiral can accommodate iodine molecules. Through van der Waals force, the two form a A blue-black complex.
Experiments have shown that iodine molecules alone cannot turn starch blue. In fact, it is the iodine molecular ion (I3) that turns starch blue. Starch is a nutrient stored in plants. It is stored in seeds and tubers. The starch content in all types of plants is high.
Starch can be regarded as a high polymer of glucose. In addition to being edible, starch is also used industrially to make dextrin, maltose, glucose, alcohol, etc. It is also used to prepare printing paste, sizing textiles, gluing paper, and pressing pharmaceutical tablets. It can be extracted from starchy substances such as corn, sweet potato, wild acorns and kudzu root.
