摘　　要：【目的】研究在发酵过程中添加麸皮和黑曲,对玉米醋减肥和降血脂作用的影响,为玉米资源的开发利用及玉米醋功能性的开发研究提供理论依据。【方法】利用营养饲料建立小鼠营养肥胖模型和高血脂模型,设普通对照组、营养对照组和3个试验组,进行小鼠血清总胆固醇、甘油三脂、高密度脂蛋白、生殖器周围脂肪质量的对比分析,研究添加麸皮和黑曲对玉米醋减肥和降血脂作用的影响。【结果】各种醋对小鼠的生长发育无不良影响,其减肥作用的强弱顺序依次为:麸皮玉米醋>麸皮黑曲玉米醋>玉米醋,对血清总胆固醇的降低作用强弱顺序依次为:麸皮黑曲玉米醋>麸皮玉米醋>玉米醋,对甘油三酯的降低作用强弱顺序依次为:麸皮玉米醋>麸皮黑曲玉米醋>玉米醋,对血清高密度脂蛋白的降低作用顺序依次为:麸皮黑曲玉米醋>麸皮玉米醋>玉米醋,降血脂作用的强弱顺序依次为麸皮黑曲玉米醋>麸皮玉米醋>玉米醋。【结论】添加麸皮和黑曲能提高发酵玉米醋的减肥作用,降低血清总胆固醇、甘油三酯、高密度脂蛋白,提高动物抗动脉硬化症的能力。[Objective] The research studied the effects of corn vinegar on reducing obesity and blood lipids. [Method] A rat high blood lipids model was set up by using high fat nutritive feed and high blood lipids feed. In the experiment, three treatments were set for research including normal feeding （fed with common diet） , nutritive feeding（fed with common diet and nutritive diet） and vinegar feeding（fed with common diet,nutritive diet and four different vinegar）. The total serum eholesterin, triglyeeride, serum hight density lipoprotein,total weight of fat around rat genitalia and arteriosclerosis exponential were analysed with corn vinegar as contrast. [Result] The result showed： all the rats grew normally during the rat feeding, the total fat weight around the genitals and fat coefficient of the nutritive control group increased apparently compared with the normal control group,with the trend of cholesterol, triglyeeride and arteriosclerosis index increasing. It showed that the rat Nutritive obesity model and the rat high blood lipids nodel were all set up successfully. In the test group, the total serum cholesterin, triglyceride, total weight of fat around rat genitalia, serum height density lipoprotein and arteriosclerosis exponential tanded to redue, Brans and aspergillus niger corn vinegar,brans corn vinegar all had better results than corn vinegar. [Conclusion] It proved that three vinegar treaments had the function of reducing obesity and blood lipids of rat and the brans and aspergillus niger vinegar was better than normal corn vinegar.
