摘要:In this study, the effect of tea polyphenols(TP) combined with modified atmosphere packaging on the quality change of Cri fish fillets in cold storage was studied, expecting to provide a new strategy for the biological preservation of fish fillets. Fresh fillets were packed in three different methods as follows: Sprayed in 0.5% tea polyphenols solution(CP group);Sprayed in 0.5% tea polyphenols combining 50% CO2 + 50% N2 modified atmosphere packaging(MAPC group);50% CO2 + 50% N2 modified atmosphere packaging(MAP group) and fresh filletsb was control group. All four groups were storaged at 0°C condition. Total bacterial count, TVB-N, TBA, K and p H were periodically assessed. The microscopic morphology of muscle tissue after 10 days cold storage was observed. After 10 d of cold storage, the TVC in the MAPC group(4.43±0.25 lg cfu/g) was obviously lower than that in the MAP group(5.04±0.65 lg cfu/g) or CP group(4.90±0.21 lg cfu/g), and even lower than that in the control group(6.14±0.17 lg cfu/g). The control group revealed the most obvious growth trend, increasing from 0.15±0.03 mg MDA/kg to 0.65±0.14 mg MDA/kg, followed by MAP group(0.15±0.08 mg MDA/kg to 0.52±0.07 mg MDA/kg), and CP group(0.13±0.05 mg MDA/kg to 0.47±0.03 mg MDA/kg), and the last was the MAPC group with the minimum amplification(0.14±0.02 mg MDA/kg to 0.47±0.13 mg MDA/kg).Tea polyphenols combining with modified atmosphere packaging is a new strategy in maintaining the quality of crisped grass carp during cold storage.
