Corn germ oil
The nutritive value of corn germ oil which produced by Doing’s Machine
The unsaturated fatty acid in corn germ oil is as high as 80%-85%, including 60% linoleic acid and oleic acid; they are helpful to patients who have cardia-cerebrovascular diseas. Linoleic acid is good to skin, it can anti-aging, moisten skin, make skin to be beautiful, glamorous and dazzling .There is no cholesterol in corn germ oil, but it can dissolve cholesterol in the blood, reduce vascular sclerosis. It also can prevent and cure senility disease, such as arteriosclerosis, diabetes, hypertension，athero- arteriosclerosis， coronary sclerosis and obesity.
Corn germ oil is rich of vitamin, such as vitamin A, vitamin D, vitamin E. They are all good to human health. Vitamin A can protect skin cells and anti-wrinkle, make skin soft and tender. Vitamin D can accelerate skin metabolism, strengthen resistance of eczema, skin ulcer. It can cure skin erythema, psoriasis, alopecia areata, and cutaneous tuberculosis. It also can promote absorption of calcium, is benefit to children’s skeletal and teeth development. Vitamin E has anti-oxidation effect, so it can protect sebum and cell membrane protein, cure xerophthalmus, nyctalopia, dermatitis, and bronchiectasia. It also can promote regeneration and vigour of human cell. It has obvious effect on preventing and curing heart disease, thrombophlebitis, and reproduction functional disorder. It is beneficial to preventing cancer.
The crude corn germ oil and finished corn germ oil which produced by Doing’s machine is fit international oil quality standard.
