响应面模型优化番石榴多糖提取工艺

Effect of Cinnamon Extract on Lipid Oxidation Stability of Frozen Pork Cake

以番石榴作为原材料,利用水提取多糖。利用响应面优化试验筛选出番石榴多糖提取的最佳工艺,结果表明,最优的提取工艺为提取次数2次、提取时间40 min、提取温度55℃、液料比35∶1(mL/g),此时多糖提取率最高,为6.82%。该法可分离番石榴多糖,证明此工艺可进行番石榴多糖的提取。

Using guava as raw material,crude polysaccharides in guava were extracted by aqueous solvent extraction.The response surface optimization test was used to screen the best process for the extraction of guava crude polysaccharides,and the results showed that the optimal extraction conditions were as follows:extraction temperature 55℃,extraction time 60 min,extraction times twice,and liquid-to-material ratio of 35∶1(mL/g).Under this condition,the average extraction rate of guava polysaccharides was 6.82%.The results showed that the alcohol precipitation method had a good effect on the separation and purification of guava polysaccharides,and could effectively adsorb guava polysaccharides,which proved that this process could extract guava polysaccharides.
