摘要

以橘类幼果为原料,对提取和结晶工艺进行优化,通过单因素试验与响应面分析法,确定最优提取工艺条件,即料液比1∶6(g/mL),提取时间100 min,碱液浓度0.4％,提取温度25 ℃;最优结晶工艺条件为pH 8,保温温度50℃,保温时间130 min,静置时间12.5 h.在此条件下橙皮苷产品得率达96.48％,含量达98.16％.该试验为从橘类幼果提取橙皮苷提供理论及技术支撑.

Abstract

Using young orange fruits as raw materials,the extraction and crystallization processes of hesperidin were optimized.Through single factor experiments and response surface analysis,the optimal extraction process conditions were determined to be a solid-liquid ratio of 1∶6(g/mL),extraction time of 100 min,alkaline concentration of 0.4％,and extraction temperature of 25 ℃;The optimal crystallization process conditions were pH 8,holding temperature of 50 ℃,holding time of 130 min,and standing time of 12.5 h.Under this condition,the yield of hesperidin products reached 96.48％,and the content reached 98.16％.The study provided theoretical and technical support for extracting hesperidin from young orange fruits.
