Device and method for germination of highland barley with Γ-aminobutyric acid enriched

(Figure 1) The present disclosure a device and a method for germination of highland barley with y-aminobutyric acid enriched and belongs to the technical field of deep processing of agricultural products. The present disclosure employs the combined treatment of steam blanching sterilization, gradient heating germination, high temperature and low oxygen enrichment to realize GABA enrichment. Steam blanching sterilization treatment can reduce bacterial growth and ensure product safety; gradient heating germination provides a material basis for GABA enrichment by promoting protein degradation into free amino acids; high temperature and low oxygen enrichment can activate glutamate decarboxylase through environmental stress, achieve GABA enrichment. The supporting equipment system includes a feeding hopper, a grain cleaning machine, a steam sterilizer, a conveying device, a germination bin, an enrichment bin, and drying equipment, which provide equipment support for the pollution-free, additive-free, and industrialized production of GABA highlandbarley. The GABA content of the product prepared by adopting the technology of the present disclosure is 27.45-53.56 mg/100g. 2-1 2-2 -2-4
