| 摘要: |
| 【目的】对超声波辅助提取双孢菇多糖的工艺进行研究，为双孢菇罐头加工过程中废弃物的综合利用提供支持。【方法】以盐渍双孢菇罐头废弃物为原料，通过单因素及正交试验探讨了液料比、超声波功率、超声波处理时间及处理温度对双孢菇多糖提取率的影响，并对超声波辅助提取双孢菇多糖的工艺参数进行了优化。【结果】优化得到超声波辅助提取双孢菇多糖的最佳工艺参数为:超声波功率560 W，超声波处理时间120 min，超声波处理温度60 ℃，液料比40 mL/g。【结论】在优化的最佳工艺条件下，双孢菇多糖的提取率为3.65%，较无超声波促进作用下普通工艺的多糖提取率提高了96.24%。 |

| Abstract: |
| 【Objective】Study was made on the optimum technology of Agaricus bisporus polysaccharides extraction by using ultrasonic to lay the foundation for solving by-products reuse in the canning process.【Method】Using Agaricus bisporus canning by-products as raw materials,single factor experiment and orthogonal test were adopted to analyze the effect of each factor in solid-liquid ratio,ultrasonic power,extraction time and temperature on the extraction percentage of the polysaccharides using ultrasonic,and the process parameters were optimized.【Result】The results indicated that the optimum condition of extraction is as follows:liquid solid ratio 40 mL/g,ultrasonic power 560 W,time 120 min and temperature 60 ℃.【Conclusion】Under this optimum condition,the extraction percentage of Agaricus bisporus polysaccharides reached 3.65%,which increased by 96.24% compared with the common technical yields. |
