In this experiment,the Xinjiang Hetian acid pomegranate was used as raw materials,pomegranate juice was filtered for bacteria removing by using different pore sizes of ceramic microfiltration membrane,and comparing the changes of membrane flux,bacteria removing rate,nutritional contents and colour value of pomegranate juice with different pore sizes(0.10,0.22,0.45 μm) of ceramic microfiltration membrane,and the suitable pore size of ceramic microfiltration membrane and optimum technological parameter of bac...
