Abstract
In order to utilize Okara Tempe (OT, a fermented product of okara) as a foodstuff, its activities were studied in vitro from the standpoint of fat digestion and bile acid metabolism. OT is ability to bind lipase, oleic acid and cholic acid was lower than that of wheat bran, suggesting that OT has less inhibitory effect on fat digestion than wheat bran after ingested. The neutral detergent fiber of OT (OT-NDF) has a stronger binding capacity for deoxycholic acid (DCA) than cellulose, suggesting that OT-NDF can increase DCA excretion. When OT-NDF was fermented by rat cecal flora, it had no effect on cholic acid metabolism. These results indicate that OT is suitable as a foodstuff.
