Abstract: The effect of Lonicera japonica Thunb. (LJT) extract on melanosis and quality deterioration of Pacific white shrimp (Litopenaeus vannamei) during cold storage was evaluated, using 4-hexylresorcinol (4-HR), a commercial melanosis inhibitor, as a positive control. The results showed that LJT inhibited polyphenol oxidase (PPO) activity and complexed copper ions in a dose-dependent manner (LJT < 16 mg/mL), indicating that LJT has the potential to inhibit shrimp melanization. Visual image and grayscale value analysis revealed that LJT and 4-HR effectively alleviated melanosis and delayed deterioration of shrimp quality stored at 4 °C, with LJT exhibiting a superior effect. LJT samples displayed a lower total number of colonies, total volatile base nitrogen value, and thiobarbituric reactive substance value than the others (p < 0.05), suggesting that LJT exerted the most potent inhibition on microbial growth and lipid oxidation in shrimps during cold storage. Consequently, LJT effectively retarded the melanosis and quality deterioration of shrimps.
