| 摘 要： | 本文研究了甘薯叶粗提物中酚类物质含量、组成、抗氧化活性、抑菌活性及其处理冷却肉后对保鲜效果的影响。采用体外抗氧化法(DPPH、ABTS自由基清除率和总还原力)及抑菌圈直径法评价各萃取(余)相的抗氧化活性和抑菌活性,筛选出抗氧化及抑菌活性强的萃取(余)相;同时通过测定pH值、硫代巴比妥酸反应物值(TBARS)、肌红蛋白含量(Met Mb%)、挥发性盐基氮(TVB-N)及菌落总数等指标评价活性强的萃取(余)相对冷却肉的保鲜效果,并利用UPLC-DAD/ESI-TOF-MS鉴定其主要酚类成分。结果表明:乙酸乙酯相的总酚含量、抗氧化活性及抑菌活性均强于其它萃取(余)相,与对照组相比,1%乙酸乙酯相能有效减缓冷却肉的pH、TBARS值、Met Mb%含量、TVB-N和菌落总数的增加,延长冷却肉的保鲜期,乙酸乙酯相中主要含有9种酚类化合物。
