The common betaine in the market mainly has betaine anhydrous, betaine hydrochloride, betaine monohydrate, compound betaine. The natural betaine is extracted from the waste molasses (containing betaine 3%-8%) produced in the process of sugar production was used as the main raw material for extraction, and ion exclusion extraction was used as the extraction process. By water elution chromatographic column, salt, sugar and betaine can be separated by elution in turn, beet alkali wash solution is collected, through evaporation, crystallization and separation, the purity of 98% anhydrous or monohydrate betaine, recovery of 70%-80%.
Methyl is a necessary group for the synthesis of methionine, choline, creatine, phospholipid, adrenaline, RNA and DEoxyribonucleic acid, which have important physiological functions. It plays an important role in immune, nervous, urinary and digestive systems. Betaine is the most effective methyl donor in vivo. The main sources of methyl in animals are betaine, choline and methionine. The theoretical methyl donor capacity of the three is 3.7:1.6:1.
Betaine metabolism can produce lysine, which provides the framework for the synthesis of carnitine. Meanwhile, it can provide active methyl as the synthetic raw material, which has the ability to increase the synthesis of carnitine. The active form of carnitine is long chain lipophthalic carnitine, namely acid-insoluble carnitine. The increase of methyl content in animals can promote the transformation of carnitine to acid-insoluble carnitine. Long chain fatty acids can be transported to mitochondria for β -oxidation by binding with carnitine to lipoacylcarnitine. The synthesis amount of free carnitine in liver increases, which enhances the transport of fatty acids, thus promoting fatty acid oxidation, and thereby enhancing the activity of lipolytic enzymes in different stages of pig and accelerating fat decomposition.
