| 中文摘要: |
| 以籼稻“冈特优37”为原料，在其发芽过程中采用真空处理，研究了真空处理时段及时长对发芽稻谷中γ-氨基丁酸（Gamma-aminobutyric acid，GABA）含量的影响。结果表明，真空处理在不同发芽时段均能促进GABA的积累，提高谷氨酸脱羧酶（Glutamic acid decarboxylase，GAD）的活性，在发芽0~6h时，促进作用尤为明显；基于此，以发芽0h为起点，进一步考察真空处理时长对GABA含量的影响，发现发芽开始时处理10h，发芽稻谷中的GABA含量最高，可达210.05±4.91mg/100g干基，较未经过真空处理的发芽稻谷高出70.38mg/100g干基，提高了50.39%。 |

| Abstract: acid (GABA) in germinated paddy. The results showed that vacuum treatment could promote GABA accumulation and increase the activity of Glutamic acid decarboxylase (GAD) in different germination periods. The promotion effect was especially obvious when paddy germinated 0~6h. Based on this, germination 0h as a starting point, the effect of vacuum treatment time on GABA content was further investigated. It was found that the highest content of GABA in germinated paddy was up to 210.05±4.91mg/100g (DB) after treatment for 10h at the beginning of germination, which was 70.38mg/100g(DB) higher than that of germinated paddy without vacuum treatment，increased by 50.39%. |
