Abstract:

To solve the problem of short shelf life of Chinese conventional fish cake, 3 preservatives including Nisin, ε - polylysine and potassium sorbate, which exhibited better respective preserving effect than other 3 preservatives including pimaricin, ethylparaben and sodium benzoate, were simultaneously added to the fish cake formula. To minimize total number of bacteria in fish cake, the optimal amounts of added Nisin, ε-polylysine and potassium sorbate were investigated using response surface analysis based on quadratic general rotation design. Results showed that the fish cake with 0.023%-0.034% of Nisin, 0.04%-0.06% of potassium sorbate and 0.022%-0.028% ofε-polylysine exhibited a minimum total number of bacteria and its shelf life at 0 - 4 ℃ was up to around 10 weeks.
