| 摘 要： | 食品中的丙烯酰胺(AA)主要是由食品中含有的还原糖和氨基酸,在120℃以上的高温油炸、煎炸或烧烤时通过美拉德反应而生成。研究了赖氨酸、甘氨酸和牛磺酸等氨基酸及由这3种氨基酸与葡萄糖或果糖生成的6种美拉德反应产物对Asn-Glc和Asn-Fru模拟反应体系中AA生成的抑制作用和反应体系的褐变程度,及其抗氧化性的影响。结果表明,氨基酸及美拉德反应产物对模拟体系中AA的生成均有显著的抑制作用;添加氨基酸及美拉德反应产物使模拟体系吸光度增高,但赖氨酸—果糖美拉德反应产物添加后模拟体系吸光度无明显变化;所有添加物均使模拟体系的DPPH及ABTS自由基清除率显著增高。

| Abstract: | Acrylamide(AA) in foods is mainly generated through Maillard reaction(MR),in which reducing sugars and amino acids reacted at the temperature above 120 ℃.Six Maillard reaction products(MRPs) are prepared by MR between three amino acids(lysine,glycine or taurine) and reducing sugars(glucose or fructose).The inhibitory effects on AA generation of three amino acids and six MRPs,and effect of their addition on browning development and antioxidant activity in Asn-Glc and Asn-Fru model system have been investigated.The results show that all additives have inhibitory effect on AA formation.At the same time,addition of three amino acids and their MRPs increase browning intensity and ABTS and DPPH free radical scavenging activity.While the browning intensity is not increased with addition of the lysine-fructose MRPs. |
