6.What Are the Common Synthesis Methods of Liquid Taurine?

Liquid taurine is not produced overnight and requires a certain process for synthesis.

Biological extraction method

Biological Extraction Method - Sourced: FirstCry

This is a relatively primitive method for extracting taurine. Taurine is widely present in the biological tissues of many animals, with the highest content found in bovine bile. However, taurine in bovine bile does not exist in a free form, but rather combines with bile acids to form taurocholic acid. Therefore, it is difficult to isolate and extract taurine from bovine bile as a raw material.

However, in some marine animals such as oysters, abalones, octopuses, jellyfish, clams, sea urchins, eels, etc., free forms of taurine are abundant, making it easier to isolate and extract them.

The method of biologically extracting taurine has been gradually phased out due to its relatively backward technology, low amount of taurine extracted, and low purity, resulting in relatively high production costs.

Fermentation

Fermentation - Sourced: Tetra Pak

Studies have shown that enzymes extracted from microorganisms such as streptococcus can separate taurine from taurocholic acid in bile, thereby obtaining free taurine, which can then be separated and purified. This patent clearly states that placing 1.5kg of bovine bile mixed streptococcus in glucose medium and culturing at 37 ℃ for 2 days can produce 45g of taurine.

Chemical synthesis

Compared with biological extraction and fermentation methods, chemical synthesis is a more economical and efficient way to prepare taurine. It can effectively solve the problems of high toxicity of raw materials, complex separation and extraction processes, long time cycles, difficult recovery, and low yield, effectively reducing production costs,

Other methods

Acrolein method: By reacting acrolein with ammonium sulfate, 2-aminoethanesulfonic acid is generated, which is further converted into taurine.

Sodium bromoethanesulfonate method: Sodium 2-bromoethanesulfonate is reacted with concentrated ammonia water, and taurine is obtained by evaporation and crystallization.

The above are common methods for synthesizing taurine, each with its own advantages and disadvantages. When choosing, it is necessary to weigh specific needs and costs.

7.What Are the Main Source of Liquid Taurine?

The food we eat in our daily lives contains taurine, which can be extracted from food or synthesized on its own.

Food source

Food Source - Sourced: Smarc

There are many sources of taurine in food, but meat and seafood have the highest content. Scallops, shrimp, clams, and other shellfish all contain a large amount of taurine, with some seafood even having higher levels than meat.

According to the national food safety standards, taurine can be added as a nutritional enhancer in blended milk, blended milk powder, flavor fermented milk, milk tablets, milk containing drinks, soybean milk/soybean milk powder, special purpose drinks, jellies and other foods.

Self synthesis

The body uses sulfur-containing amino acids (cysteine, methionine, etc.) as raw materials to synthesize taurine through a series of enzymatic reactions. The rate of taurine synthesis varies greatly among different age groups of the human body, with very little self synthesis during infancy and early childhood. Therefore, taurine needs to be added to formula milk powder.

Adults generally do not require additional supplementation, but during intense exercise, the body’s demand for taurine increases, and its own synthesis is no longer sufficient to meet the demand; In old age, it is important to obtain sufficient taurine from the diet.
