Water Binding Capacity of Vegetable Fiber

식이섬유의 수분결합력에 관한 연구

The water binding capacity(WC) of acid detergent fiber(ADF) was estimated. The WBC of raw vegetables ranged from 5. 1g to 24.7g water/g ADF. WBC was high in pepers and low in welsh onions. The correlation coefficients between WBC and fiber components were examined to fled which component is responsible for the deteruuning ability to bind water. The correlation coefficient between WBC and cellulose was +0.8. The binding capacity of water by fiber was affected positively by cellulose. fermentation increased in WBC of ADF. Changes of no in accordance with pH changes were evaluated at pH 2, 5.2 and 6. In all cases, WBC was high In weak acid and neutral.
