摘　　要：为了生产富含GABA的保健啤酒,以富含γ-氨基丁酸(简称GABA)的发芽糙米和大麦芽为主要原料,研究发芽糙米添加量、酒花添加量、酵母接种量和发酵温度等因素对富含GABA保健啤酒的影响。正交试验结果表明,最佳工艺条件为:发芽糙米添加量35%,酒花添加量0.24%,酵母添加量0.9%,发酵温度9℃。在此条件下,啤酒的感官评分为91.2分。在此条件下生产的富含GABA保健啤酒具有良好的色泽、香气、口味和泡沫,其GABA的含量高达68.8 mg/L,具有很强的保健功能。此外,其各项理化指标和微生物指标均符合国标要求。To produce healthy beer rich in γ-aminobutyric acid（short for GABA as below） with germinated brown rice and barley malt as the main raw material,the effects of the amount of germinated brown rice,the amount of hops added,the amount of yeast inoculation and the temperature of fermentation on the GABA-enriched beer were studied.The optimum conditions were as follows：the amount of germinated brown rice 35%,the amount of hops 0.24%,the yeast addition 0.9% and the fermentation temperature 9 ℃.Under this condition,the beer＇s comprehensive score was 91.2 points.The GABA-rich beer,which was produced under this condition,had a good color,aroma,taste and foam,its GABA content was as high as 68.8 mg/L,and it had a strong health function.In addition,the physical and chemical indicators and microbial indicators were in line with national standards.
