黑加仑色素提取工艺参数研究

通过对提取试剂、提取温度、时间、酸浓度等各因素的试验,研究了黑加仑色素的提取方法,并确定浸提法提取黑加仑色素的最优提取条件.为期黑加仑色素在食品、医药等领域的开发与应用提供了理论依据.结果表明:提取溶剂1％盐酸+无水乙醇、提取温度应取50℃,提取时间应为15 min,pH 6,料液比应为1∶10为最佳提取条件,4个因素对黑加仑色素的影响程度由大到小依次为:A(浸提温度)＞B(浸提时间)＞D(料液比)＞C(溶液pH值).

Study on Technological Parameter of Black Currant Pigment

Through the extraction reagents,extraction temperature,time,acid concentration and other factors,studied the black currant pigment extraction in order to determine the pigment extraction method to extract the optimal extraction of black currant conditions.Gallon black currant pigment in food,medicine and other fields of development and application provides a theoretical basis.The results showed that extracting solvent was 1% hydrochloric acid and ethanol,extracting temperature was 50℃,extracting time was 15 min,pH 6,solid-liquid ratio was 1∶10 were the optimum extracting conditions,four factors on the degree of influence of black currant pigment descending order was A(extracting temperature)>B(extracting time)>D(solid-liquid ratio)>C(pH).
