The epidermis of wheat is mainly composed of cellulose, and the edible value is not high; In addition to containing more cellulose, the aleurone layer also contains protein, vitamins and fats, and has high nutritional value. The endosperm contains a lot of starch and a small amount of protein; In addition to protein, sugar, fat and cellulose, the embryo also contains a large amount of B vitamins.

Vitamin E and enzymes.

Due to the different components of each part of wheat, the content of nutrients in flour with different grinding precision is also different. The main ingredient in flour is sugar, which accounts for 70% to 80%.
