Abstract

Protein content of winged bean is almost the same as soybean, but the beany flavor is more poweful than soybean. Therefore the protein of winged bean was isolated prior to use as raw material of yogurt. This research was aimed to determine the potency of hypocholestrolemic activity of yogurt protein isolate of winged bean through in vivo bioassay by using Sprague Dawley male rats. The treatments of the research were yogurt feed treatment with concentration of yogurt 0 (standard feed without yogurt as a control), 2, and 4 g yogurt/day as low and high concentration treatment respectively for 4th weeks after hypercholesterol feed treatment for 1 week. The blood lipid profile of rats, including triglyceride, cholesterol total, High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL) cholesterol were analysed on the 2nd and 4th weeks for the yogurt feed treatment while for before yogurt feed treatment, the evaluation were based on the adaptation phase and the 1st week for hypercholesterol phase. The result of this research showed that the blood triglyceride, cholesterol total, LDL increased, and the blood HDL decreased in hypercholesterol phase before yogurt feed treatment. The potency of hypocholestrolemic of yogurt from protein isolate of winged bean was shown by the decreasing of blood triglyceride, cholesterol total, LDL and increasing the HDL cholesterol after the yogurt feed treatment with low and high concentration. That indicated that yogurt that was made of protein isolate of winged bean could reduced cholesterol.
