The chemically synthesized GABA is produced with 2-pyrrolidone as raw material which is a kind of highly toxic chemicals, and trace residues 2-pyrrolidone exists in this kind of product. Food GABA is made of L-glutamate as raw material by fermentation of lactic acid bacteria which does not contain 2-pyrrolidone. The results of analysis of 2-pyrrolidone in products of GABA can identify which production technique of GABA is, chemical synthesis or fermentation of lactic acid bacteria. This analysis method is available in Beijing Gleckes Bio-engineering Technology Co. LTD.
