Abstract

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.

Key words: corn porous starch, heat-moisture treatment, serum lipids, neutral steroid
