Study on extraction and stability of coriolus versicolor purple pigment
摘要
Abstract
Using ultrasonic extraction method,solvent,ultrasonic time,temperature and pH value were chosen as extraction factors to optimize ultrasonic extraction process of coriolus versicolor pigment through single factor experiment and orthogonal experiment L9（34）.The stability of coriolus versicolor purple pigment was also investigated under common oxygenant,reducer,food additives or metal ion medium.The optimum extraction technology was ethanol as solvent,extraction temperature at 60℃,pH2,ultrasonic time with 105min,the total content of coriolus versicolor pigment and the yield was used as indexes,its content was detected by spectrophotometry and A480 reached 1.130.Coriolus versicolor pigment was stable under different system in peroxide,common food additives,carbonic drink or soda.Coriolus versicolor pigment had good value on application and exploitation.关键词
