after the structural modification were compared. The results revealed that the water solubility of the flavonoids modified by glucosylation was significantly increased while the oil-water partition coefficient was just slightly reduced. Moreover, after glucosylation, the products have good anti-inflammatory and antioxidant effects. Interestingly, the taste property (bitterness and sweetness) of the glucosylated
环糊精葡糖基转移酶 (CGTase) 通常用于生产环糊精,但很少发现其在类黄酮修饰中的应用。在本研究中,研究了以 CGTase 为催化剂对柑橘类黄酮的酶促转化,以从柑橘类黄酮二糖苷的单糖苷代谢物生产许多新型多糖基化衍生物。在优化条件下,糖化产物的收率达到80%。比较了结构修饰前后柑橘类黄酮的水溶性和水分配系数。结果表明,经糖基化修饰的黄酮类化合物的水溶性显着提高,而油水分配系数略有降低。此外,糖基化后,该产品具有良好的抗炎和抗氧化作用。有趣的是,葡萄糖基化产品的味道特性(苦味和甜味)得到了改善。Taste-Sensing System 的评估表明,葡萄糖基化产物的味道与附着的鼠李糖基(苦味)和葡萄糖基(甜味)密切相关,表明黄酮类化合物的味道改善主要归因于添加糖基。本研究展示了一种新的分子工程方法,可提高某些柑橘类黄酮的水溶性和改善味道,这可能在功能性食品工业中具有潜在应用。改善了葡糖基化产
