Properties

In the food industry, food preservatives and preservatives are released slowly, improving the antiseptic effect, prolonging the shelf life of food and improving the taste of food. In food manufacture, they are mainly used to eliminate peculiar smell, improve the stability of flavor, flavor and pigment, and enhance the emulsifying capacity and moisture resistance. It is widely used in the pharmaceutical excipients industry. It is mainly used to increase the stability of drugs, prevent drug oxidation and decomposition, improve the dissolution and bioavailability of drugs, reduce the toxic and side effects of drugs, and cover up the peculiar smell and odor of drugs. In the cosmetics industry, it can prevent the damage of cosmetic whitening agent, oxidation and browning of blood acid, improve the whitening effect and reduce irritation.
