Abstract:

In order to clarify the effects of ultrahigh pressure processing（UHP） on the activities of cellulose, the CMC and FPA enzyme activities of cellulose in C. militaris juice were studied by pressure, holding time, temperature, ethanol concentration, times of pressure and pH. The result showed that the optimal pressure, holding time, temperature, ethanol concentration, times of pressure and pH of the enzyme were 400 MPa, 10 min, 35 ℃, 30 %, pH 4.0-7.0 and pressure for 1 times, respectively. Under the optimum conditions, the CMC enzyme activity were enhanced by 82.07%, 52.41%, 87.22 %, 54.48%, 67.52% and 66.67 %, and the FPA enzyme activity was enhanced by 97.37%, 61.4 %, 69.4 %, 61.4%, 1.31% and 33.91 %, respectively. The experiment illustrated that the ultra-high pressure treatment could enhance the activity of cellulose in C. militaris juice.
