E3S Web of Conferences(2020)
Abstract
Rosa roxburghii residue as raw material, we studied the extraction process of dietary fiber from rosa roxburghii pomace by chemical method. The effects of temperature, time, pH, solid-liquid ratio on the IDF yield under the effect of alkali and acid were explored by single factor experiments and orthogonal experiment. The results showed that the optimal condition of extracting IDF was as follows: the 60 mesh rosa roxburghii pomace were 80 min in water bath at 60°C under the condition of the solid-liquid ratio 1:15 and the pH 12; and then rosa roxburghii pomace were 100 min in water bath at 50°C on the condition of the solid-liquid ratio 1:15, and pH 3.0 after rinsing, the average IDF yield which reached (86.3±1.0)%. This experiment provides experimental basis for the selection of dietary fiber raw materials, and also provides theoretical basis for increasing the added value of rosa roxburghii .
