【摘要】 為有效提取香菇中的可溶性含氮化合物,通過對高速組織搗碎機、膠體磨和高壓均質機3種機械物理破壁的比較,最終確定采用高壓均質機以達到最佳的破壁效果,從而釋放菌體細胞內大量的可溶性含氮化合物。通過對均質工藝單因素及正交實驗的探討,得到最適工藝條件為均質壓力40 MPa、均質溫度50℃、均質料液比1∶7、均質次數2次,可溶性氮釋放率可達到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 ...
