Problems solved by technology

At present, the problems existing in fermentation production mainly include low acid production level of strains, high content of miscellaneous acids, and other amino acids produced by fermentation metabolism, especially neutral amino acids such as leucine, its molecular weight and chemical isoelectric point, and branched chain amino acids. It is very close to the extraction, and the ion exchange process is generally used to separate the impurity acids, and the process is complicated. The main disadvantage is that the ion exchange resin needs to be regenerated and eluted, and a large amount of acid and alkali will be used in the regeneration process, which makes the product purity low. And the yield is low; a large amount of ammonium nitrogen waste liquid will be produced after elution and regeneration, which will not only cost a lot of money due to the consumption of a large amount of acid and alkali, but also cause great pollution to the environment. consume a lot of water
Backward production technology limits scale production
Because the content of other amino acids in the product is difficult to solve, domestic high-end API products cannot meet the EU standards, so they cannot enter the international market to participate in the competition of APIs

Description

technical field [0001] The invention relates to the field of pharmaceutical and chemical processing, in particular to a process for preparing branched-chain amino acids and its application. Background technique [0002] Branched Chain Amino Acids (BCAAs) are essential amino acids for the human body. On the one hand, proper supplementation can reduce the catabolism of protein in muscles and promote gluconeogenesis, which can improve strength and anaerobic exercise capacity; Chain amino acids are oxidized and decomposed in the body to produce ATP more efficiently than other amino acids. Supplementing BCAA can effectively reduce the formation of 5-hydroxytryptamine (5-HT), reduce the fatigue felt by the human body, and provide energy and willpower for the body for long-term endurance exercise . [0003] The main functions of BCAA are: restore the body's water and electrolytes, quickly restore glycogen reserves, enhance muscle endurance, and rebuild muscle protein. All in all,...
