Abstract:

In order to extend the application of dynamic high-pressure microfluidization technology, this technology was used to the pretreatment of mushroom fruit bodies. The optimal pretreatment conditions were explored by single-factor and orthogonal experiments through evaluating the yield of lentinan. Results indicated that the optimal pretreatment conditions were pretreatment pressure of 140 MPa and material-liquid ratio of 1/60. Under the optimal pretreatment conditions, the yield of polysaccharides was up to 6.755%. Compared with the control group, the extraction rate of polysaccharides was significantly improved.

Key words: dynamic high-pressure microfluidization, lentinan, pretreatment, extraction
