The preservation effect of gelatin based edible coatings with nisin on the shelf-life of chilled fresh chicken breast was evaluated.The results showed that the nisin-gelatin edible coatings had a significant inhibitory action on the total number of colonies of chicken breast,and the inhibitory effect increased with the strengthen of nisin 's concentration(P < 0.05);the addition of nisin to the gelatin based edible coatings showed no significant effect on the center pH of chicken breast during fresh-keeping storage(P > 0.05),but significantly improved the color of chicken breast(P < 0.05);the drip loss of chicken breast was significantly reduced during storage by the treatment of gelatin based edible coatings(P < 0.01).It illustrated that the nisin-gelatin edible coatings was effective in the fresh-keeping of chicken breast.
