Optimization of Extraction Technology for Insoluble Dietary Fiber from Fortuneana pyracantha Fruits by Response Surface Methodology
摘要
Abstract
The alkali-catalyzed hydrolysis method was applied to extract insoluble dietary fiber （IDF） from the fruits of Fortuneana pyracantha and main process conditions were optimized by one-factor-at-at-a-time experiments and response surface methodology. The extraction rate and purity of IDF were investigated with respect to NaOH concentration, extraction time, extraction temperature and material-to-liquid ratio. The results showed that the optimal extraction conditions were NaOH concentration of 1.00% （g/g）, extraction time of 3.00 h, extraction temperature of 77.8 ℃, and material-to-liquid ratio of 1：17 （g/mL）. Under the optimal extraction conditions, the extraction rate and purity of IDF were 56.89% and 92.74%, respectively.关键词
