1. Description of Grape Skin Extract Powder

The main active ingredients of grape skin extract are polyphenols and resveratrol, which are natural antioxidants and have the effects of preventing chronic inflammation, cardiovascular disease, cancer and diabetes. It is dark-purple free flowing powder with characteristic odor and taste. Widely used in the fields of medicine, health care products and dietary supplements.

Internationally, grapes are mainly used to make wine. The annual output of international wine is 26.76 million tons, followed by grape juice and fresh food. In China, fresh food is the main food. In recent years, with the adjustment of China's agricultural industrial structure, the planting area and output of grapes have shown a linear upward trend. At the same time, grapes discard a large amount of grape skins as residues in the processing process. For example, grapes used for winemaking will produce more than 400,000 tons of grape skins every year. These grape pomace are discarded at will, causing pollution to the surrounding environment on the one hand. It also causes waste at the same time. Therefore, how to improve the extraction rate and stability of grape skin polyphenols has become the focus and focus of current research, and the market application prospect is very broad. The production of grape skins and seeds from grape processing waste belongs to the rational use of grape capital and should have a good development prospect.
