Types of coarse grains
Coarse grains mainly include cereals (corn, millet, Redmi, black rice, purple rice, sorghum, barley, oats, wheat, etc. ), miscellaneous beans (soybeans, mung beans, red beans, black beans, broad beans, peas, etc. ) and tuber (sweet potato, yam, potato, etc. ).
The nutrients contained in various coarse grains have their own strengths, and oats are rich in protein; Millet is rich in tryptophan, carotene, iron and B vitamins. Beans are rich in high-quality protein and fat; Sorghum is rich in fatty acids and iron. Compared with coarse grains, polished white rice and polished white flour lost some nutrients during grain processing, especially vitamin B 1 and inorganic salts.
Coarse grains are simple to process and retain many nutrients that are not found in flour and rice. In terms of nutrients, the content of protein in coarse grains is relatively low, while the content of starch, cellulose, inorganic salts and B vitamins is rich.
Extended data:
Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, nicotinic acid and vitamin A, etc. Due to different varieties and environmental conditions, the nutritional components vary greatly. Judging from the content of protein, the wheat planted in continental arid climate region is hard and transparent, with protein content as high as 14 ~ 20%, and the gluten is firm and elastic, which is suitable for baking bread.
Wheat grains born under wet conditions contain protein 8 ~ 10%, which is soft and poor in gluten. It can be seen that the influence of geographical climate on the product formation process is very important.
Except for human consumption, only a small amount of flour is used to produce starch, alcohol, gluten and so on. The by-products after processing are all high-quality feed for livestock. Eating whole wheat can reduce the content of estrogen in blood circulation, thus achieving the purpose of preventing and treating breast cancer; For menopausal women, eating unrefined wheat can also alleviate menopausal syndrome.
