摘要
对茶多酚(Teapolyphenols,TP)降低莴笋(LactucasativaL.)酱菜中亚硝酸盐含量的途径进行了探讨。结果表明,TP通过与NO-3作用、抑制与NO-2形成有关的细菌的活动以及与NO-2直接作用而降低酱菜中的NO-2含量,其中以TP与NO-2的直接作用为其主要降低途径。TP的最佳抑制浓度为0.02%~0.04%,该浓度对NO-2的阻断率达50%~64%。
The way of reducing nitrite content in pickled lettuce with polyphenols was studied.Results showed that tea polyphenols can react with NO - 3,restrain the activity of bacterial which produces NO - 2,as well as react with NO - 2 directly which is the main cause of reducing nitrite content in pickled lettuce.Tea polyphenols of 0 02%—0 04% concentration gave the best result,and the reducing rate of NO - 2 reached 50%_64% with this concentration.
