### Effect of the CFS on TVB-N Content of Pacific White Shrimp  
Figure 4 shows changes on the TVB-N content of Pacific white shrimp during transportation, retailing, and domestic storage. At the beginning of the storage, the TVB-N value of control samples was about 5.14 mg N/100 g and that of test samples was 4.86 mg N/100 g. After the storage of 6 days, the TVB-N value of shrimp samples was significantly increased (Figure 4). As shown in Table 3, group CK1 stored at 0 \({}^{\circ}\)C was obviously lower than group CK2 and CK3 at the storage of 6 days and group CK3 exposure to temperature fluctuation during transportation and retailing was slightly higher than group CK2 stored at 4 \({}^{\circ}\)C. After domestic storage, group SA1, group SA2 and group SA3 treated by CFS from _A. sobria_ inhibited TVB-N production by 34.89%, 29.86% and 17.85%, respectively.

Different letters (a–e) at each line denote significant differences (\(p<0.05\)) between means according to [PERSON]’s multiple range test. Asterisks show significant statistical differences among samples during different cold chain logistics at the same storage time (\(p<0.05\)).
