摘要
Abstract
[Objective]To optimize the technique of sub-critical water extraction of
polysaccharide from Pleurotus ostreatus. [ Method] Polysaccharide was
extracted from P. ostreatus with sub-critical water, and the
polysaccharide content was determined by phenol sulfuric acid method.
Through single-factor test and orthogonal test, effects of temperature,
extraction time, solid-liquid ratio on the yield were investigated, the
optimum extraction conditions were determined. [Result] The order of
influencing factors was as follows; extraction temperature > solid-liquid
ratio > extraction time, temperature has extremely significant difference
on polysaccharide yield. The optimal technique was 150t, solid-liquid
ratio 1:20 g/ml, 5 MPa, extracting 7 min. Under the above conditions, the
yield of polysaccharide was up to 13. 65%. [Conclusion] The study provides
basis for industrialization production of P. ostreatus polysaccharide.关键词
