초록

In order to anticipate the physiological function of dietary fibers, glucose and bile acid retarding effects were experimented by using in vitro methods based on dialysis for commercial fibers and dietary fiber residue of food samples. The glucose retarding effect in commercial fibers increased in the order of alginic acid, guar gum, CM-cellulose, citrus pectin > apple pectin > $\alpha$-cellulose and the effect in food fiber residues increased in the order of sea mustard > Korean cabbage, apple > rice bran, barley, soybean, and tangerine. The bile acid retarding effect in commercial fibers increased in the order of citrus pectin, guar gum > CM-cellulose, alginic acid > apple pectin > $\alpha$-cellulose and the effect in food fiber residues increased in the order of barley, rice bran > sea mustard > tangerine > Korean cabbage, soybean > apple. The higher the retarding effect of glucose movement through the dialysis membrane, the more effective the control of the human blood glucose level. As the retarding effect of bile acid movement across the dialysis membrane increased, the human serum cholesterol level correspondingly reduced. Consequently these in vitro methods can be used as a preceding test before undertaking animal and human experiments to predict the physioloical effects of fiber residues from diverse food samples as well as commercially refined fibers.
