摘要
以大豆为原料,研究了大豆发芽期间生理活性和γ-氨基丁酸(GABA)等物质的变化,同时对GABA等指标间的相关性进行了分析。结果表明:大豆种子在浸泡12h后吸水量趋于稳定,随着发芽时间的延长,豆芽生长增快、呼吸作用增强,游离氨基酸、可溶性蛋白和GABA含量增加。同时相关性分析表明,大豆发芽期间GABA含量与芽长、呼吸强度、游离氨基酸和可溶性蛋白含量呈显著正相关。综合考虑大豆芽菜品质和GABA累积量等因素,大豆在30℃发芽48h,是生产富含GABA豆芽的合适条件。
The changes of physiological activity,γ-aminobutyric acid（GABA） and other substance in the germinating soybean were studied and the correlation between GABA and other indicators were analyzed.The results showed that the water absorption was stable after 12 hours when soybean seeds were soaked.The bean sprouts growth,respiration,free amino acids,soluble protein and GABA content were increased with the germination time prolonging.The correlation analysis showed that GABA content and bud,breathing strength,free amino acids and soluble protein content was significantly positively related during soybean germination.At 30 ℃ for 48 hours of germination is suitable condition for the production of GABA-rich bean sprouts considering the quality of bean sprouts and GABA accumulation in soybean sprouts.
