In the present study, different intensities of UV-A were applied to compare their effects on growth, bioactive compounds and hypoglycemia-related enzyme activities in broccoli and radish sprouts. The growth of sprouts was decreased after UV-A irradiation. A total of 12 W of UV-A irradiation resulted in the highest content of anthocyanin, chlorophyll, polyphenol and ascorbic acid in broccoli and radish sprouts. The highest soluble sugar content was recorded in sprouts under 8 W of UV-A irradiation, while no significant difference was obtained in soluble protein content among different UV-A intensities. Furthermore, 12 W of UV-A irradiation induced the highest glucosinolate accumulation, especially glucoraphanin and glucoraphenin in broccoli and radish sprouts, respectively; thus, it enhanced sulforaphane and sulforaphene formation. The α-amylase, α-glucosidase and pancrelipase inhibitory rates of two kinds of sprouts were enhanced significantly after UV-A irradiation, indicating UV-A-irradiation-treated broccoli and radish sprouts have new prospects as hypoglycemic functional foods.
在本研究中，采用不同强度的UV-A照射，以比较其对西兰花和萝卜芽苗菜生长、生物活性化合物及降血糖相关酶活性的影响。UV-A照射后芽苗菜的生长受到抑制。总共12W的UV-A照射使西兰花和萝卜芽苗菜中的花青素、叶绿素、多酚和抗坏血酸含量达到最高。在8W的UV-A照射下，芽苗菜中的可溶性糖含量最高，而不同UV-A强度下的可溶性蛋白质含量无显著差异。此外，12W的UV-A照射分别诱导西兰花和萝卜芽苗菜中硫代葡萄糖苷的积累量最高，尤其是萝卜硫苷和萝卜硫素；因此，它促进了萝卜硫素和萝卜硫烯的形成。UV-A照射后，两种芽苗菜的α-淀粉酶、α-葡萄糖苷酶和胰脂肪酶抑制率显著提高，表明经UV-A照射处理的西兰花和萝卜芽苗菜作为降血糖功能食品具有新的前景。
