Product Introduction
Plant sterols are functional components that exist in the free state or in combination with fatty acids and sugars, and are widely found in the cell membranes of vegetables, fruits and other plants.
Plant sterols are divided into 4-methyl-free sterols, 4-methyl-sterols and 4,4 '-dimethyl-sterols. 4-methyl-free sterols mainly include Β -sitosterol, stigmosterol, rapeseed sterol and so on. The structure of plant sterols is basically similar to that of animal sterols, but the difference is the number of methyl groups connected to c-4 and the difference of c-11 side chain. It is the small difference in these side chains that leads to different physiological functions.
Plant sterols are non-saponifiable plant oils, industrial soybean and rape seed seed as raw materials, extraction of vitamin E when the by-product, or from the production of rice bran oil when the non-saponifiable matter, after extraction, refined products.

Product Function
Phytosterols are important nutrients that have a variety of physiological functions, including lowering cholesterol, anti-inflammatory, antioxidant, etc. One of the most well-known is that it has a cholesterol-lowering effect, which can help the body maintain normal cholesterol levels, thereby helping to prevent cardiovascular disease. In addition, plant sterols can also help reduce inflammation, and have certain preventive and therapeutic effects on chronic diseases such as arthritis and gout.
Compared with other plant sterols, plant sterols are absorbed and metabolized in a special way in human body. It can be metabolized by glutathione transferase in the body and converted into a compound called phytosteroside. This compound has a stronger antioxidant effect in the human body and can help protect cell membranes and cell structures from damage caused by free radicals.

Product Application
Food and nutritional supplements: Plant sterols are added to food and nutritional supplements to help lower cholesterol levels in the blood. For example, plant sterols are added to some yogurts and yogurt drinks, powdered milk, and dietary supplements, which are designed to lower blood cholesterol by reducing intestinal absorption of cholesterol.
Cosmetics and skin care products: Because plant sterols have antioxidant and anti-inflammatory effects, they can regulate skin metabolism and inhibit skin inflammation, so they are used in sunscreen skin care and anti-aging skin.
Animal Husbandry and aquaculture: Plant sterols are also used in the livestock and aquaculture industry to promote animal growth and increase antioxidant capacity. For example, in aquaculture, plant sterols are used to improve the health status and growth performance of aquatic animals.
Medical field: Plant sterols have certain effects of reducing blood cholesterol, inhibiting mammary gland hyperplasia and regulating immunity, and also have the effect of preventing prostate hypertrophy and inhibiting tumor. This makes it have certain application potential in the field of medicine.
