Taurine is one of the most abundant free amino acids in mammalian tissues and has been used in a wide variety of healthy functional foods.


Taurine occurs as colorless or white crystals, or a white crystalline powder. It is soluble in water, and practically insoluble in ethanol (99.5%). The pH of a solution prepared by dissolving 1.0g of Taurine in 20mL of freshly boiled and cooled water is between 4.1 and 5.6.

Functions and Applications

As an excellent food additive, taurine has been widely used in developed countries such as Europe, America and Japan. In order to ensure the healthy growth of infants and young children, the United States, Japan and other countries have clearly stipulated that the content of taurine in infant dairy products should not be less than 0.16mg/100mL. It can be used as a nutritional fortifier in food and beverages for pilots, astronauts, athletes, etc. to enhance physical fitness and relieve fatigue.

Taurine is added to animal feed as a feed additive, which can prevent and treat fish diseases and brighten the eyes of pets such as cats and dogs.
