After the corn germ is pressed, the germ cake is obtained.
Main components of corn germ cake:
Component content (%)
Moisture 7.5 ~ 9.5
Fat 3 ~ 9.8
Coarse protein 23-25
Crude fiber 7-8
Nitrogen-free extract 42-53
Ash 1.4 ~ 2.6
It can be seen from the above ingredients that corn germ cake is a kind of nutrient based on protein, and it should be a better nutritional fortifier.
However, corn germ cake is often mixed with corn fiber, especially germ cake has a bad smell, so it is generally treated as feed. If corn starch enterprises have good germ separation effect and high germ purity, then corn oil is extracted by solvent, and the obtained corn germ powder is a good food additive after desolventizing and deodorizing, which can be used in cakes, biscuits and bread.
Adding germ powder to biscuits can improve the crispness of biscuits, and adding germ powder to bread can reach up to 20%, which greatly improves the protein of bread, but the appearance, bulkiness and taste are not much different from the original. This germ powder can be used to extract isolated protein and make high-quality corn germ protein beverage.

Nutritional components of corn germ oil
1, unsaturated fatty acids
There are two kinds of fat in the diet, one is animal fat and the other is plant fat. Animal fat contains more saturated fatty acids, which may lead to atherosclerosis, aggravate sebum overflow and promote skin aging.
Plant fat contains more unsaturated fatty acids and vitamins. Corn germ oil contains a variety of unsaturated fatty acids. It can prevent atherosclerosis, coronary atherosclerosis and thrombosis, and has positive preventive and therapeutic effects on various senile diseases and diabetes.
2, vitamins
Vitamins are divided into fat-soluble vitamins (such as vitamin A, vitamin D, vitamin E and vitamin K) and water-soluble vitamins (such as vitamin B, vitamin C, vitamin PP and folic acid). Various vitamins have their unique effects in beauty and skin care.
Corn germ oil is rich in vitamins A, D and E, among which vitamin A has a good effect on improving vision, promoting the development of epithelial tissues and bones, and the growth and development of fetus. Vitamin D can promote the absorption of calcium by human body and contribute to the development of children's bones. Rich vitamin E has the functions of "softening skin and beautifying" and "delaying aging".
Vitamin A: It can maintain the function of skin cells, make skin soft and tender, and has the effect of anti-wrinkle and wrinkle removal. Lack of vitamin A will reduce the function of epithelial cells, resulting in decreased skin elasticity, dryness, roughness and loss of luster.
Vitamin D: It can promote skin metabolism, enhance resistance to eczema and scabies, and promote bone growth and tooth development. Taking vitamin D can inhibit the formation of skin erythema and treat psoriasis, alopecia areata and skin tuberculosis. When the body lacks vitamin D, the skin is easy to fester.
Vitamin e: the role of vitamin e in beauty and skin care can not be ignored. Because the oxidation of human sebum is one of the main causes of skin aging, and vitamin E has antioxidant effect, thus protecting sebum in skin, protein of cell membrane and moisture. It can also promote the regeneration and vitality of human cells and delay the aging process of cells.
In addition, it can also promote the use of vitamin A by human body; Can play a synergistic role with vitamin C, protect skin health and reduce skin infection; It has a "moisturizing" effect on collagen fibers and elastic fibers in the skin, thus improving and maintaining the elasticity of the skin;
It can promote the blood circulation of the skin, make the skin get enough nutrition and moisture, and thus keep the skin soft and shiny; It can also inhibit the formation of pigmented spots and senile spots, reduce facial wrinkles, whiten skin and prevent and treat acne.
