Medium gluten flour: common flour, the most common flour, with protein content of 9.5- 1 1.5%, which is used to make most Chinese snacks such as steamed bread, steamed stuffed bun, jiaozi, pancakes, noodles and dough twists. Low-gluten flour: Also known as cake flour, protein content is 6.5-9.5%. It can be made by mixing four parts of medium gluten flour and one part of corn starch (other starches are acceptable). Suitable for making loose, crisp and inflexible snacks such as cakes, biscuits and egg tarts. Self-raising flour: The self-raising flour sold in the supermarket is flour mixed with a certain proportion of chemical additives such as yeast and baking powder. When it is used, only water is needed, which can save fermentation time. Self-raising flour should be used according to the instructions on the package, because different product formulas may have different methods of use. Whole wheat flour: Wheat seeds consist of bran, endosperm and germ. Bran is hard and difficult to digest, and germ is rich in oil and rancidity, so flour is made of endosperm. But bran provides rich dietary fiber, which is very beneficial to human digestion. Therefore, whole wheat flour is a common flour, which is made of endosperm and ground bran. For bread, cakes, noodles and other different uses, the proportion of bran added, the size and shape of bran are also different, so in fact, whole wheat flour is not a crude product directly ground from whole wheat grains, but a more complicated refined product. In the menu of West Point, what kind of flour is needed will be specially indicated. Generally, medium gluten powder can be used instead of high gluten powder or low gluten powder, and there is no obvious difference. At present, the flour sold in the grain area of domestic supermarkets is mainly medium-gluten flour suitable for Chinese pasta, and the labeling of "refined flour", "special flour" and "gluten-rich flour" is to indicate the processing fineness of flour, not the gluten content of flour. "jiaozi flour" is medium gluten flour and "bread flour" is high gluten flour. In the imported food area of large supermarkets, you can also buy completely imported flour with detailed classification and specific uses, as well as all kinds of ready-mixed flour containing other powder raw materials that can be used directly, but the price is also very expensive.
