By autoclaving, we obtained a polyphenol and dietary fiber from pea (Pisum sativum L.) pods in parallel without acid or alkali treatment or organic solvent extraction. Rats fed a high-sucrose (HS) diet containing 3% autoclaved extract (AE) for 4 wk exhibited significantly lower serum triglyceride and total cholesterol levels than rats fed a HS diet. AE and soluble dietary fiber (SDF) from AE exhibited pancreatic lipase inhibitory activity at 13.3 mg/mL in vitro. AE and insoluble dietary fiber (IDF) from AE adsorbed cholesterol. In total, 30% and 10% of a cholesterol micelle were significantly adsorbed by 2,000 mg of AE and 100 mg of IDF from AE in 7 mL, respectively. The amount of bifidobacteria in the cecum of the AE group was significantly increased compared with that in the HS group. These results suggest that AE has hypolipidemic, bifidogenic potential.
