Response Surface Methodology for Optimization of Extraction Process for Soluble Dietary Fiber from Grape Pomace with Hydrochloric Acid
摘要
Abstract
Objective： To optimize the extraction of soluble dietary fiber（SDF） from grape pomace with hydrochloric acid.Methods： One-factor-at-a-time experiments,mathematical modeling based on Box-Behnken experimental design and multiple regression analysis and response surface analysis were carried out to investigate the individual and interactive effects of various process conditions on extraction yield of SDF and their significance.Response surface and contour plots were drawn with extraction yield of SDF as a function.Results： The optimal conditions for SDF extraction were 0.40 mol/L hydrochloric acid as extraction solvent at a material-to-liquid ratio of 1：12（g/mL） and 75 ℃ for an extraction duration of 90 min.Under the optimal extraction conditions,the yield of SDF was up to 47.56 mg/g,which was close to the model-predicted value.Conclusion： The developed regression equation can be well fitted with experimental results and is reasonable,reliable and applicable for actual prediction.关键词
