摘要
讨论了利用微波辐射萃取法从南瓜皮中提取果胶的不同因素的影响,通过实验确立了微波条件下提取果胶的最佳工艺条件为:用盐酸调pH值为1.8,用水作为溶剂,料液比为1∶20,微波辐射功率为600W,辐射时间为4min,乙醇(体积分数)为60%,提取率可达到16.9%。
The paper gives diversity factors for extraction of pectin from pumpkin peel with microwave,and builds optimally technology conditions of extraction of pectin from pumpkin peel with microwave.The results showed that the optimum conditions were as follows： pH value of extraction of 1.8 with HCl,use the water as solvent,the volume of water to the weight of orange peel of 20∶1,microwave power of 600W,radiation time of 4 min,the concentration of ethanol 60%,The output ratio of pectin of 16.9%.
