Study on Extraction Technology of Polysaccharide from Pleurotus ostreatus

摘要

To study the extraction technology of polysaccharide from Pleurotus ostreatus. In order to explore the influence of temperature, time, and solid-liquid ratio on polysaccharide yield, single factor test had been done. The optimum extraction conditions was obtained though orthogonal test and interactive analysis: extraction temperature 50°C, extraction time 2h, and solid-liquid ratio 1:30. Under those conditions, the extraction rate of Pleurotus ostreatus polysaccharides was 28.79%.
