Flour is directly ground into powder by peeling wheat or other grains, but starch is a polysaccharide obtained by separating protein and other substances from flour.
The difference between starch and flour is quite big, because they are two completely different things, mainly in composition, appearance, feel and use.
I. Components:
Flour contains more nutrients, rich in protein, fat, carbohydrates and dietary fiber, but the main components of starch are more than 80% carbohydrates and more than 10% water.
Second, the appearance:
The appearance is very recognizable. Compared with starch, the color of flour is a little yellow. The color of starch is white and purer.
Third, feel:
Rubbing flour with your fingers will feel slippery, and rubbing starch will feel astringent.
Fourth, the application:
Flour is mainly used to make steamed bread, fried dough sticks, noodles and other staple foods, and starch is mainly used to make soup, such as laver and egg soup.
