摘 要:
以山楂果心为原料,采用微波-盐酸-盐析法,通过单因素及L9(34)正交试验分别研究了盐酸浓度、微波功率、微波时间、饱和硫酸铝溶液用量、料液比等因素对山楂果心提取液中果胶量及得率的影响。结果表明微波功率的影响最大,料液比的作用次之,饱和硫酸铝溶液用量的影响高于盐酸浓度,微波时间的影响最小;山楂果心中果胶提取的最佳条件为盐酸浓度0.05mol/L、微波功率800W、微波时间50s、料液比1:15,饱和硫酸铝溶液用量7mL,在此条件下果胶得率达5.87%。

摘 要:
Hawthorn pulp was used as the raw material to explore the effects of hydrochloric acid concentration,microwave power,microwave treatment time,saturated aluminum sulfate amount and material/liquid ratio on the extraction efficiency of pectin by one-factor-at-a-time method and orthogonal array design.The results indicated that the effect of microwave power revealed the strongest impact on extraction rate of pectin followed by material/liquid ratio,saturated aluminum sulfate amount,hydrochloric acid concentration and microwave treatment time.The optimal parameters for pectin extraction from hawthorn pulp were hydrochloric acid concentration of 0.05 mol/L,microwave power of 800 W,microwave treatment time of 50 s,material/liquid ratio of 1:15 and 7 mL of saturated aluminum sulfate.Under the optimal extraction conditions,the yield of pectin was 5.87%.
