摘要
对山竹壳果胶提取条件进行筛选和优化,为山竹壳果胶资源的有效利用提供参考。以山竹壳为原料,盐酸为酸性介质提取山竹壳中果胶,通过单因素试验,研究不同提取温度、pH、提取时间、液料比对果胶提取率的影响。在此基础上,采用响应面法对果胶提取条件进行优化。响应面方程模型的p<0.0001<0.01,模型失拟项p=0.0515>0.05,说明其模拟效果较为合理。优化后最佳提取条件为液料比20︰1(mL/g)、pH 1.5、提取温度70℃、提取时间1.5 h。此条件下,果胶提取率为14.56%,与理论值14.92%较接近。
The pectin extraction condition from mangosteen rind was screened and optimized to provide reference for the effective utilization of pectin resources in mangosteen rind.The mangosteen rinds as test materials,hydrochloric was used to extract the pectin of mangosteen rind.The effect of ratio of liquid to material,pH,extraction temperature and extraction time on extraction ratio of pectin by single factor experiment was investigated.Based on single factor experiment result,the extraction condition was optimized by response surface method.The p value for response surface equation was below 0.0001(p<0.01),and the effect of simulation was relatively reasonable(p=0.0515>0.05).Optimum condition was obtained as follows:ratio of liquid to material 20︰1(mL/g),pH 1.5,extraction temperature 70℃,and extraction time 1.5 h.The pectin extraction yield was 14.56%,which had better fitting with the theoretical value(14.92%)under the optimal condition.
