The Source And Application Of γ-aminobutyric Acid

The content of GABA in plant tissue is extremely low, usually between 0.3 and 32.5 μmol/g. It has been reported in the literature that the enrichment of GABA in plants is related to the stress response experienced by the plant. When subjected to stress such as hypoxia, heat shock, cold shock, mechanical damage, and salt stress, it will lead to the rapid accumulation of GABA. It has become a research hotspot to process plant food raw materials into GABA-rich functional products after a certain stress treatment or through microbial fermentation to increase the GABA content in the body. As a novel functional factor, GABA has been widely used in the food industry. Foods developed using raw materials such as GABA-rich germinated brown rice, soybeans and broad beans are already on the market.
