Starch includes sweet potato flour, which is a type of starch.

There are many types of starches, the common ones include mung bean starch, potato starch, wheat starch, sweet potato starch, water chestnut starch, lotus root starch, water chestnut starch, corn starch, starch, sweet potato starch, arrowroot starch, cassava starch, and sago starch. Coconut starch, crystal powder, cornstarch, etc.

Starch is the main component of human food and an important industrial raw material. At present, starch is mainly produced by crops through photosynthesis, which converts sunlight energy, carbon dioxide and water.

Chemical properties of starch

Many chemical properties of starch are similar to glucose, but because it is a polymer of glucose and has its own unique properties, the chemical properties of starch are used to change starch in production. Molecules can obtain two major categories of important starch deep-processing products.

Starch hydrolyzate products use the hydrolysis properties of starch to degrade starch molecules and produce products with different DPs. Under the action of catalysts such as acids or enzymes, starch's α-1,4 glycosidic bonds and α-1,6 glycosidic bonds are hydrolyzed, and various products such as dextrin, oligosaccharides, maltose, and glucose can be generated.
