There are many kinds of starch, such as mung bean starch, potato starch, wheat starch, sweet potato starch, water chestnut starch, corn starch and so on. We usually refer to sweet potato starch used for thickening, which has the characteristics of white color, poor luster and easy precipitation after thickening. Specifically, starch and flour are two different concepts.

1. Flour is directly ground into powder after wheat or other grains are peeled. Starch is a polysaccharide obtained by separating protein from flour, which is mainly used in food, adhesive, sizing fabric, western medicine tablets, glucose production, maltose and so on.

2. If cooking, flour is mainly used for making steamed bread and frying (fried dough sticks, tenderloin, fried wings in KFC, etc. ). Starch is generally used to make soup! The soup made of starch is clear, sticky and smooth, with good taste and vision.

3. From the appearance, flour is white, but compared with starch, it is slightly yellow, and starch is very white, because starch is a polysaccharide substance obtained by separating protein and other substances from flour. So the color is purer.

4. In terms of hand feeling, if you rub a little flour with your fingers, it will be very slippery, and the starch will feel astringent. The feeling of rubbing starch with your hands is very similar to rubbing lotus root starch with your fingers. I feel a little somersault when I rub it.
