中文摘要: 为探究绿茶粉添加对黑色冲调粉抗氧化及消化特性的影响,在黑色冲调粉中加入绿茶粉,比较不同梯度的添加量对黑色冲调粉抗氧化特性和体外消化的差异。研究结果表明:随着绿茶粉添加量的增加,黑色冲调粉表现出抗氧化性增强,淀粉水解率下降的趋势。添加绿茶粉的黑色冲调粉DPPH自由基清除能力、总抗氧化能力(total antioxidant capacity,T-AOC)和总还原力的吸光度分别为97.29%、12.34 U/g、0.715。绿茶粉添加有助于提高黑色冲调粉的抗氧化能力、降低消化特性的功能。
Abstract:To explore the effect of green tea powder on the antioxidant and digestive properties of black powder.Add green tea powder to the black powder,comparison of the different amounts of green tea powder on the antioxidant properties and in vitro digestion of black powder.Research indicates,as the amount of green tea powder increases,black powder has stronger antioxidant resistance,the starch hydrolysis rate of black powder was reduced.Add green tea powder to black powder,its DPPH scavenges free radicals,total antioxidant capacity(T-AOC)and absorbance of total reducing power was 97.29%,12.34 U/g,0.715.The addition of green tea powder helps to improve the antioxidant capacity of the black powder and reduce the digestive properties.
