| 摘 要： | 为有效提取香菇中的可溶性含氮化合物,通过对高速组织捣碎机、胶体磨和高压均质机3种机械物理破壁的比较,最终确定采用高压均质机以达到最佳的破壁效果,从而释放菌体细胞内大量的可溶性含氮化合物.通过对均质工艺单因素及正交实验的探讨,得到最适工艺条件为均质压力40 MPa、均质温度50℃、均质料液比1∶7、均质次数2次,可溶性氮释放率可达到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 ratio of 1︰7,homogenization of two times. |
