Taurine exists in almost all living things, especially in major organs of mammals, such as heart, brain and liver. The most abundant are marine fish, shellfish, seaweed, such as squid, octopus, shrimp, shellfish oysters, shells, clams and so on. Fish is rich in taurine, such as mackerel, bamboo pod fish, sardines and so on. The content of taurine in laver is about 65438 0% of the total dried laver, even higher than that in some marine animals.
In fish, the taurine content in the black part of fish back is 5 ~ 10 times higher than that in other white parts. Therefore, more intake of this kind of food can get more taurine. Taurine is easily soluble in water, so it is very important to drink soup cooked by fish and shellfish at the same time when eating. In Japan, "fish sauce" brewed with fish and shellfish is rich in taurine. Except beef, the content of taurine in meat is very small, which is only 1% ~ 10% of that in fish and shellfish. Natural taurine is far from meeting people's needs because of its dispersion and low content.
marine animal
The liver of land animals is rich in taurine, especially in the bile of cattle. Marine animals such as squid, squid, fish, shellfish, etc. There is more in the body.
Taurine. It is reported that taurine is extracted from oysters, scallops and squid, and taurine is extracted from squid viscera. It is reported that taurine is extracted from pearl oyster by enzymatic method, which has complex technology and high yield.
The number is extremely low.
basin
There are many ways to extract taurine from laver, among which the method with the best quality and without adding any chemicals in the production process is the integrated membrane system method. This method does not
Only natural taurine can be extracted from laver, and amino acids such as protein, polysaccharide and laver oil can also be separated. After the integrated membrane system extracts natural taurine into the industrial production stage, it will break the artificial synthesis of cattle.
Market structure of sulfonic acid.
Although the price of natural taurine is high, its whole production process is green, without any pollution to the environment and any artificially added chemicals. Natural taurine products have biological activities that synthetic chemicals do not have. These outstanding characteristics will make natural taurine have a broad market prospect.
chemical synthesis
Because taurine is dispersed in natural organisms and its content is small, the amount extracted from natural raw materials is limited. Therefore, people mainly rely on chemical synthesis to obtain taurine in industry. Since 1950, countries all over the world have begun to carry out artificial synthesis research. There are nearly 10 synthetic processes of taurine, among which chemical synthesis methods such as ethanolamine method and dichloroethane method have been industrialized. In addition, according to Japanese patent report, taurine can be prepared by fermentation. Taurine producers are mainly concentrated in Japan, the United States, Europe and other developed countries and regions, and their output has increased rapidly. There are less than 10 normal production enterprises in China, and the taurine produced is mainly used for export and medicine, of which 90% is exported and only 6% is used as food additive.
