研究了1.0 mmol L− 1甘露糖处理下青花菜芽中花青素、总硫代葡萄糖苷、萝卜硫素的含量以及γ-氨基丁酸（GABA）的代谢。结果表明，甘露糖处理提高了谷氨酸（Glu）含量和二胺氧化酶（DAO）活性，降低了γ-氨基丁酸转氨酶（GABA-T）活性，有利于GABA的合成。甘露糖处理提高了二胺氧化酶（DAO）、多胺氧化酶（PAO）和4-氨基丁醛脱氢酶（ABALDH）的活性，提高了游离多胺的转化率。同时也有利于花青素、总硫苷和萝卜硫素的富集。这些结果表明甘露糖处理对发芽青花菜中的GABA和其他促进健康的代谢产物具有显著的增强作用。
The contents of anthocyanins, total glucosinolates, sulforaphane, and the metabolism of γ-aminobutyric acid (GABA) in broccoli sprouts grown under 1.0 mmol L−1of mannose were investigated. The results showed that mannose treatment improved glutamate (Glu) content and the activity of diamine oxidase (DAO), and reduced γ-aminobutyric acid transaminase (GABA-T) activity, which enriched GABA biosynthesis. Mannose treatment enhanced the activities of diamine oxidase (DAO), polyamine oxidase (PAO), and 4-aminobutyraldehyde dehydrogenase (ABALDH), and increased the conversion rate of free polyamine. At the same time, it is also beneficial for the enrichment of anthocyanins, total glucosinolates and sulforaphane. These results indicated that mannose treatment has a significant enhancement effect on GABA and other health-promoting metabolites in germinated broccoli.
