摘  要:
目的:研究速溶罗汉果粉制备新工艺。方法:将罐组式动态逆流提取与膜分离、浓缩技术结合,用于提取罗汉果提取物的开发,并研究各工艺的最佳参数。结果:罐组式动态逆流提取的最佳参数为提取温度80℃,料水比1:10(g/mL),提取时间30min,利用罐组式动态逆流提取可以大大减少后续浓缩的工作量,提取率大于99%;超滤膜的最适宜孔径20000D;反渗透浓缩的最高质量浓度8g/100mL,溢留水中甙5的质量浓度为0.002g/100mL。结论:为速溶罗汉果粉的制备提供了一种具有节能、高效,且可以最大限度保护罗汉果有效成分和风味物质的制备新工艺。

摘  要:
Objective:To study the preparation parameters of instant powder of Momordica grosvenori Swingle Fruit.Methods:Multi-stage countercurrent extraction technology,ultrafiltration technology and reverse osmosis technology was adopted in the preparation.Results:The optimum conditions for multi-stage countercurrent extraction technology were as follows:temperature 80℃,the ratio of material to water 1:10,time 30 min.The extraction ratio was more than 99% under such conditions.The optimum pore size of ultrafiltration membrane was 20000 D.The maximum admissible concentration of reverse osmosis technology was 8%,and under this condition,the loss of mogroside Ⅴ was less than 0.01%.Conclusion:The proposed method is efficient,energy-saving technology,and the effective components and flavor components were reserved.
