Study on extraction condition of monascus color with low citrinin and high color value
摘要
Abstract
Tow step methods were used to extract monascus color from red Koji rice,the first step extraction was used to remove citrinin,the second step was used to extract monascus color.The results of experiments were obtained as follows：The optimal conditions of the first step extraction were：acetic ether as extracting solvent,pH 2.5,50℃ extracting temperature,60min extracting time,1：15 the ratio of solid material to solvent,3 extracting frequencies.The optimal conditions of the second step extraction were：85% ethanol concentration as extracting solvent,60℃ extracting temperature,50min extracting time,1：20 the ratio of solid material to solvent,2 extracting frequencies.Under above conditions,the monascus color with low citrinin and high color value could be obtained.The received rate of monascus color was 8.31%,with 18625U/kg color value and 1.37mg/kg citrinin content.关键词
