Effect of tea polyphenols combining with packaging on quality of weever in cold chain logistics

The present study was undertaken to investigate the influences of air or tea polyphenols combined with two different packaging ways on the quality of weever in cold chain logistics process by simulating the four different phase of the storage(-18 ℃),transportation( 0 ℃),marketing( 2 ℃) and household refrigerator storage( 4 ℃).The result indicated that the tea polyphenols combined with packaging had an obvious buffer action on the quality of weever in cold chain logistics process.At the end of the logistics( 20 d),the values of TVB-N,TBA and total plate count were 18.11 mg /100 g,7.07 mg / kg and 5.68 lg CFU / g,respectively and all obvious lower than that of control groups which ensure the weever was still in the scope of the safety in the late logistics. Hence,in the condition of the faultiness of the low temperature cold chain logistics,this research had an significant influence on the maintain of fish quality.
