摘要
讨论了利用微波辐射萃取法从西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: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600 W,辐射时间为4 min,乙醇浓度为60%,提取率可达到17.8%。
The paper gives diversity factors for pectin from watermelon peel with making use of microwave extraction,and build optimally technology conditions about pectin from watermelon peel with making use of microwave extraction.The results showed that the optimum conditions were as follows： pH value of extraction of 1.8 with HCl,use the water as sol-vent,the volume of water to the weight of watermelon peel is 20∶1,microwave power is 600 W,radiation time is 4 min,the concentration of ethanol 60%,The output ratio of pectin 17.8% was obtained on the optimum conditions.
