中文摘要: 以干燥的夏橙皮渣为原料,先用复合磷酸盐碱性溶液浸泡24 h,采用超声波辅助提取法对果胶进行了提取。以果胶提取率为考察指标,研究了盐酸浓度、液料比、水解温度、水解时间、超声波处理时间对果胶提取的影响。结果表明,盐酸浓度为0.15mol/L、液料比为30mL/g、水解温度为70℃、水解时间为30min、超声波处理时间为40min时,果胶提取率高达20.67%,试验重现性好。
Abstract:Dried summer orange peel was adopted as raw materials in the study.After materials were soaked with phosphate solution for 24 h,pectin was extracted through ultrasound-assisted extraction method.The effects of hydrochloric acid concentration,liquid-solid ratio,hydrolysis temperature,hydrolysis time and ultrasonic treatment time on extraction rate of pectin were studied.The results showed that when the hydrochloric acid concentration was 0.15 mol/L,liquid ratio was 30 mL/g,hydrolysis temperature was 70℃,hydrolysis time was 30 min,and ultrasonic treatment time was 40 min,the extraction rate of pectin reached 20.67%and the experimental reproducibility was good.
