The effects of four reaction parameters, including different pressure, pressure holding time, temperature and pH of solution on the microbial inactivation of fresh-cut lotus (Nelumbo nucifera Gaertn Elian No.4)were investigated by single factor experiments and orthogonal experiment. Results showed that the optimal sterilization process for fresh-cut lotus were as follows: 400 MPa, 25 min, 50 ℃ and pH 4.5. Under these conditions, the total number of colonies was 60.3 cfu/g.
