Wheat Germ Processing Technology
Wheat germ is a by-product of wheat flour production. Due to its high content of biological enzymes and oil, entering into flour milling production will affect the production efficiency and the shelf life of final wheat flour, larger flour mills adopt the production process of embryo extraction to separate this by-product. Wheat germ from flour factory has been pressed into thin slices, and the tissue structure has been damaged. The oil contained in the wheat germ will be decomposed quickly under the action of biological enzyme and water. High acid value will make wheat germ lose its processing value. Especially in hot summer, the shelf life of pressed wheat germ is calculated in hours. (Read more about wheat germ oil extraction method >>)
