Research progress on γ-aminobutyric acid accumulation in soybean and its product development

Soybean as an indispensable legume in the world is an important source of nutrients for human diet. γ-aminobutyric acid (GABA)as an important health-related nutritional factor and a non-protein amino acid, its natural content in soybean is quite low and it's accumulation could be affected by many factors, which will influence the full play of GABA functions and the quality promotion of GABA-enriched soybean products. Therefore, it's quite significant to study the influence factors of GABA accumulation and the development progress of its products in soybean for the guidance of accumulation and effective utilization of GABA in soybean. In this paper, the latest research progress of the main influence factors of GABA accumulation in soybean and its product development were reviewed. The existing problems in the field was analyzed and the research emphasis in the future was forecasted, in order to provide theoretical basis for the research on soybean GABA accumulation and GABA-enriched soybean product development.
