摘　　要：在浸泡条件下,探讨通气处理对发芽糙米生理活性及γ-氨基丁酸(GABA)等主要物质含量的影响。结果表明: 0．5-2．0 L·min-1的通气处理有利于发芽糙米生长和呼吸代谢,加速淀粉和可溶性蛋白质降解,促进还原糖和游离氨基酸生成。当通气量为1．0 L·min-1时,发芽糙米中GABA累积量最高。Brown rice was soaked into distilled water, and aerated with air at 0, 0.5, 1.0, 1.5 and 2.0 L · min^-1 for germination. The changes of respiration rate and shoot length of germinating brown rice were observed. The contents of GABA and other essential substances in germinating brown rice were analyzed. It was indicated that at the range of 0.5- 2.0 L · min^-1 , the shoot growth and respiration rate of germinating brown rice were enhanced with the increase of temperature. The contents of free amino acids and reducing sugar in germinating brown rice increased while protein and starch decreased. Meantime the optimum aeration ratio for GABA accumulation was 1.0 L · min^-1.
