研究不同陈酿期松针酵素中活性酶及体外抗氧化能力的变化规律,并采用Pearson法研究其相关性.结果 表明,随着陈酿时间的延长,松针酵素中超氧化物歧化酶(SOD)、淀粉酶、蛋白酶、脂肪酶和纤维素酶活力均逐渐降低,陈酿4年后,分别下降36.79％、88.26％、43.52％、82.63％、28.03％.松针酵素具有良好的抗氧化能力,在陈酿初期,还原力、超氧阴离子自由基清除率、羟基自由基清除率和ABTS自由基清率均达到最高值,分别为0.54、92.93％、60.57％、98.89％,且均随着陈酿时间的延长而逐渐降低,而DPPH自由基清除率随着陈酿时间的延长而增加.5种活性酶活力与5个抗氧化指标具有一定的相关性,可以通过测定松针酵素...

The changes of active enzymes and in vitro antioxidant ability of pine needle Jiaosu in the different aging stages were studied,and the correlation was analyzed by Pearson method.The results showed that the activities of superoxide dismutase(SOD),amylase,protease,lipase and cellulase in pine needle Jiaosu decreased gradually with aging time,and decreased by 36.79%,88.26%,43.52%,82.63%and 28.03%after 4 years aging,respectively.The pine needle Jiaosu had good antioxidant activity.In the early stage of aging,the reducing power,superoxide anion radical scavenging rate,hydroxyl radical scavenging r...
