Effect of Heat-Moisture Treated Corn Porous Starch on Lipid Metabolism in Rats
摘要
Abstract
Objective: To investigate the effect of heat-moisture treated corn porous starch on lipid metabolism in rats. Methods:Totally 32 female Sprague-Dawley rats were randomly divided into 4 groups including control group and three other groups as high-fat blank group, high-fat porous starch (PS) group and high-fat heat-moisture treated corn porous starch (HTMPS) group. After adaptive feeding with a basal diet for a week, the rats from the control group were still fed with the basal diet and those from high-fat groups were given a high fat diet. After 4 weeks, all rats were sacrificed for the analysis of triglyceride (TG), cholesterol (TC) in serum and liver, and bile acid in small intestine and feces. Results:By feeding corn porous starch and heat-moisture treated corn porous starch, the contents of TC, TG and non-HDL-C in serum, atherosclerosis index (AI) and TG/HDL-C ratio in serum as well as TC content in liver and abdominal fat content decreased significantly (P<0.05);the fecal excretion of neutral steroid and bile acid increased significantly (P<0.05). Compared with HTMPS group, the rats from PS group revealed a reduction in serum TC level, AI, TG/HDL-C ratio and abdominal fat, and an increase in fecal bile acid excretion and bile acid in small intestinal contents. Conclusion:PS is more successful in reducing cholesterol than HTMPS. Therefore, porous starch can reduce the risk of hyperlipidemia caused by high-fat diet, and has a significant role in preventing cardiovascular diseases.关键词
