The invention belongs to the technical field of table vinegar production, and provides a method for co-fermenting red date and 
coix seed vinegar with high gamma-
aminobutyric acid content through combination of 
monascus, 
lactic acid bacteria and 
spore bacteria. The method comprises steps as follows: mixing germinated 
coix seeds, 
coix seed 
bran, enzymatically decomposed red date juice and L-
sodium glutamate, and carrying out 
alcohol fermentation by mixed 
bacteria of 
monascus with high yield of GABA, 
saccharomycetes and 
lactic acid bacteria; after the 
fermentation is finished, supplementing 
sugar, red date juice, L-
sodium glutamate, 
lactic acid bacteria, 
spore bacteria and 
acetobacter pasteurianus, and carrying out aerobic 
acetic acid and 
lactic acid fermentation; and after the 
fermentation is finished, adding lactic acid bacteria for anaerobic secondary 
lactic acid fermentation. The red date and coix seed vinegar with high gamma-
aminobutyric acid content is prepared through 
raw material optimization, strain optimization proportioning, multiple times of fermentation enrichment, 
ageing, blending, sterilization and filling. In a final product, the content of non-volatile acid is larger than or equal to 2.0 g / 100 mL, the content of flavone is larger than or equal to 120 mg / 100 mL, the content of GABA is larger than or equal to 280.0 mg / 100 mL, the content of 
Monacolin K is larger than or equal to 120 mg / 100 mL, and the effects of resisting oxidation, lowering 
cholesterol and lowering 
blood pressure are achieved.
