Abstract:

Effects of processing pressure, pH and pressure duration on the total bacterial count of fresh sea cucumber were investigated by single factor test, and then these factors were optimized by orthogonal test design. Moreover, fresh-keeping effects of two pressure modes, namely continuous and cycle pressure modes, were compared. The results showed that under the conditions of the processing pressure 500 MPa, pH 6.5 and pressure duration 30 min, the best sterilization effect on fresh sea cucumber was achieved, and the fresh-keeping effect of the cycle pressure mode was superior to that of another mode .

Key words: ultrahigh pressure, fresh sea cucumber, sterilization, pressure
