Take DPPH··ethanol solution as the oxidant system to research on the DPPH··scavenging capacity of the liquid fermented vinegar from north fruits like hawthorn, apple, tangerine, beach jujube, kiwi fruit, pear, mulberry, persimmon, medlar, kernel-apricot etc. and grains like corn, sorghum, millet, wheat, buckwheat, Job"s-tears, purple rice etc. it was found that the scavenging effect on DPPH··of the grain vinegar and fruit vinegar after brewing and sterilization was significantly higher than that of their corresponding vinasse, and With the increase of addition, scavenging rate is gradually increased. To most fruit vinegar and grain vinegar, the scavenging effect on DPPH··are stronger than acetate, and acetic acid has some effective but is not functional, consequently it"s other ingredients that really played scavenging effect in the fermentation of vinegar.

本实验采用DPPH··乙醇溶液为氧化体系，研究北方产山楂、苹果、蜜橘、滩枣、猕猴桃、酥梨、桑椹、水柿、枸杞、仁用杏等数十种果品，以及玉米、高粱、小米、小麦、荞麦、薏米、黑米等数十种粮食作物为原料的液态发酵醋对自由基DPPH··的清除能力，结果发现经过酿造杀菌后的成品果醋及粮食醋对DPPH··的清除作用明显高于其相对应的酒醪；并且随着加入量的增加其清除率也逐渐增高，其中大多数果醋及粮食醋对DPPH··的清除作用均强于醋酸，发现醋酸对DPPH··虽然有一定的清除率但是作用不大，因此说明真正对DPPH··起到清除作用的还是发酵醋中的其他成分。
