【摘要】 為有效提取香菇中的可溶性含氮化合物,通過對(duì)高速組織搗碎機(jī)、膠體磨和高壓均質(zhì)機(jī)3種機(jī)械物理破壁的比較,最終確定采用高壓均質(zhì)機(jī)以達(dá)到最佳的破壁效果,從而釋放菌體細(xì)胞內(nèi)大量的可溶性含氮化合物。通過對(duì)均質(zhì)工藝單因素及正交實(shí)驗(yàn)的探討,得到最適工藝條件為均質(zhì)壓力40 MPa、均質(zhì)溫度50℃、均質(zhì)料液比1∶7、均質(zhì)次數(shù)2次,可溶性氮釋放率可達(dá)到78.84%。

【Abstract】 To extract effectively soluble nitrogen compounds from mushrooms,broken by waring blender,colloid mill and high-pressure homogenizer were studied.A great deal of soluble nitrogen compounds was obtained due to the best optimal wall-broken efficiency by high-pressure homogenizer.Through the single factors and orthogonal test,soluble nitrogen release rate achieved to 78.84% under the optimal process conditions,such as homogeneous pressure of 40 MPa,homogeneous temperature of 50℃,material to liquid ...
