- Abstract
By analyzing the influencing factors of alkaline extraction of soluble dietary fiber (SDF) from Rosa roxburghii pomace produced in the old Yellow River channel of Kaifeng, the optimization parameters of Rosa roxburghii pomace SDF extraction process were obtained. On the basis of a single factor experiment affecting the extraction rate of SDF from Rosa roxburghii pomace, a three factor three-level response surface experiment was conducted by selecting liquid to material ratio, extraction temperature, and alkaline concentration. The optimal extraction conditions were obtained as follows: liquid to material ratio (mL: g) of 30: 1, extraction temperature of 77 ℃, and alkaline concentration of 9.7 g/L. The SDF extraction validation experiment of Rosa roxburghii pomace was conducted under these conditions, and the average actual extraction rate was measured to be 16.843%, which is basically consistent with the predicted value, indicating that the optimized parameters are reliable. The water holding capacity of SDF obtained from Rosa roxburghii pomace is (13.41±0.09) g/g, oil holding capacity is (4.72±0.17) g/g, and expansion capacity is (11.95±0.05) mL/g.
