Mixed Tocopherols
Brief Introduction:
Mixed tocopherols, the hydrolyzate of natural vitamin E, are a mixture of various tocopherols extracted and concentrated directly from the deodorized distillate of vegetable oils.
It is one of the sources of vitamin E in food and the most important natural high-efficiency oil-soluble antioxidant on the market, which is widely used in whole milk powder, butter, margarine, meat products, processed aquatic products, dehydrated vegetables, fruit drinks, frozen food, convenience food and other fields.
