Embodiment 1
[0020] Soak the large yellow croaker frozen to death with crushed ice in 2.50mg / L ozone water for 5 minutes, take out and soak in 2.00g / L tea polyphenols and 1.00g / L Nisin solution that have been fully dissolved in sterilized water for 30 minutes, take out in 10.00g / L chitosan solution (dissolved in 1% acetic acid) soaked for 30 seconds, drained to form a film, 70% CO 2 / 30%N 2 Modified atmosphere packaging. At the end of the shelf life of the refrigerated large yellow croaker (4°C) control group for 6 days, the total number of bacteria and volatile basic nitrogen (TVB-N) in the treatment group decreased by 3.8logCFU / g and 17mg / 100g, respectively, and the shelf life was extended by more than 16 days.
Embodiment 2
[0022] Soak the large yellow croaker frozen to death with crushed ice in 1.30mg / L ozone water for 7 minutes, take out and soak in 1.80g / L tea polyphenols and 1.20g / L Nisin solution that have been fully dissolved in sterilized water for 30 minutes, take out in 10.00g / L L chitosan solution (dissolved in 1% acetic acid) was soaked for 30 seconds, drained to form a film, and 60% CO 2 / 40%N 2 Modified atmosphere packaging. At the end of the shelf life of the refrigerated large yellow croaker (4°C) control group at 6 days, the total number of bacteria and TVB-N in the treatment group decreased by 2.9logCFU / g and 15mg / 100g, respectively, and the shelf life was extended by more than 12 days.
Embodiment 3
[0024] Rinse the crushed and frozen large yellow croaker with 5.00mg / L ozone water for 2 minutes, soak in 2.00g / L tea polyphenols and 1.80g / L Nisin solution that have been fully dissolved in sterilized water for 30 minutes, take out the 10.00g / L shell Polysaccharide solution (dissolved in 1% acetic acid) soaked for 30 seconds, drained to form a film, 75% CO 2 / 25%N 2 Modified atmosphere packaging. At the 9th day at the end of the shelf life of the refrigerated large yellow croaker (0°C) control group, the total number of bacteria and TVB-N in the treatment group decreased by 3.5logCFU / g and 17mg / 100g, respectively, and the shelf life was extended by more than 9 days.
