Objective To study the effect of acidificated soybean powder on rats blood lipid and antioxidation.
Methods According to weights and blood cholesterol leval, male SD rats were divided into three groups: ordinary contrast group, high fat contained group and 10% acidificated soybean powder contained group.After six-week feeding stage, the change of serum lipid, apolipoprotein and antioxidation system level were observed in rats.
Results Acidificated soybean powder significantly reduced low-density lipoprotein cholesteral(LDL-C), total cholesteral(TC), triglyceride(TG)and serum apoB level, increased high-density lipoprotein cholesteral(HDL-C)and serum apoA level as well as apoA/apoB rate.The serum surperoxide dismutase(SOD), glutathione peroixdase(GSH-Px)and Se level in acidificated soybean powder contained group were significantly higher than those of other groups, and malondialdehyde(MDA)level was significantly lower.
Conclusion Acidificated soybean powder was able to reduce rats blood lipid and antioxodate.Ithad the probable future to be a vascular2disease2protected food.
