Pea starch: peas are shelled, dried and polished; Corn starch: corn is made by crushing, sieving, precipitation, drying, grinding and other processes; Potato starch: potatoes, including potato skins, are cooked, dried and finely ground, with fine texture and white color.

Second, the usage is different:

Pea starch is a good starch, and it is better to use it when frying crispy meat. First, it is moderate in hardness and crisp in taste. When pea starch is used to make crisp broth or stew, the starch skin will not fall off. Bean jelly and cold rice noodles are mostly made of pea starch.

Corn starch is a common one, which has strong hygroscopicity and is suitable for meat sizing. The effect of ingredients after sizing is: soft and smooth. Corn starch can not only remove the odor of food, but also enhance the flavor, which can not only maintain the original flavor of food, but also make the taste more tender, fresh and crisp. Suitable for chicken, duck, fish and shrimp and other dishes with tender texture or tender parts.

Potato starch (potato starch) is sticky and stable, but it has poor water absorption and is suitable for cooking. Due to the low gelatinization temperature, the loss of nutrition and flavor caused by high temperature can be reduced. When potato starch is used for thickening, it can ensure the original flavor of ingredients to the greatest extent. It can also be used to make highly transparent sauces, and the sauces made are transparent in color and very beautiful.

Extended data:

Pea starch is rich in protein, carotene and other nutrients, which can effectively enhance human disease resistance and rehabilitation.

Corn starch is often used as a coagulant for puddings and other foods. Common ready-made pudding premixes in the market all contain corn starch.

Because potato starch has strong water absorption and gelatinization characteristics, adding potato starch to the printing and dyeing pulp of large dyeing and weaving factories and paper mills can make the impregnated cloth and paper have good color and better quality.
