Grape seed oil is refined from grape seeds by the most advanced cold pressing method. It is beautiful and natural light yellow or light green. It is one of the most popular and effective varieties in base oil. Grape seed oil is non-toxic, so it is suitable for children, pregnant women, the elderly and athletes. The main components of grape seed oil are linoleic acid and proanthocyanidins, and the content of linoleic acid is more than 70%. Linoleic acid is a kind of essential fatty acid which cannot be synthesized by human body.

Grape seeds are most famous for their two important elements, linoleic acid and oligo proanthocyanidin. Linoleic acid is essential for human body and can not be synthesized by human body. It can resist free radicals, anti-aging, help absorb vitamin C and E, strengthen the elasticity of circulatory system, reduce the damage of ultraviolet rays, protect collagen in skin, improve venous swelling and edema, and prevent melanin deposition.

Production process:

The production process of grape seed oil generally adopts pressing method, leaching method and refining method.

Press method press method also known as "physical press method", is to use external force to squeeze out the oil in the oil, not suitable for other chemical solvents, avoid the residue of organic solvents in the oil. The pressing technology retains the effective components of grape seed polyunsaturated fatty acids, protein, dietary fiber, vitamins, trace elements and other nutrients beneficial to human body to the greatest extent, which is more suitable for special supplement for human health care.

The oil produced by leaching (refining) process is also called leaching oil, which is to extract oil with organic solvent (such as gasoline, ethanol, etc.). The leaching method is an oil making process that uses solvent oil (No.6 light gasoline) to soak the oil raw materials and extract the oil at high temperature. The "oil" extracted at first is a mixture of organic solvent and oil, which can not be eaten. It can only be eaten after a series of refining processes (dewaxing, degumming, dehydration, deodorization, deacidification, decolorization and other chemical treatments). This kind of oil is generally light in color, and the initial natural smell in the material seeds is light or no obvious smell. The extraction process can extract almost all the oil in the oil, which has high economic benefits and is the most popular processing method in the modern oil industry.

technological process:

Grape seed screening → crushing → softening → steam frying → pressing → crude grape seed oil → coarse filtration → degumming / dephosphorization → deacidification → decolorization → deodorization → low temperature crystallization → dewaxing → grape seed oil products
