一种血红密孔菌色素提取工艺优化及稳定性研究
Study on Process Optimization and Stability of Pigment Extraction of Pycnoporus sanguineus
摘要
Abstract
In this study,a strain containing a large amount of red pigment in wild Pycnoporus fruitbody is taken as test material,and 3 factors,namely,extraction temperature,ethanol concentration and extraction time are used for the extraction process of optimization,and the stability of the fruiting body of pigment is studied.The results show that:optimum extraction conditions of blood red hole fruiting body pigment,70%ethanol,extraction temperature of 85℃, extraction time 80 min,pigment content 3.84 mg/g.The research results of pigment stability shows that the pigment has good stability,such as temperature,oxidizing agent, reducing agent,metal ion and so on. It has great development and utilization value in food and industry, and it is worth further research.关键词
