Le résumé fourni par la source
Melanosis is a major postharvest quality defect in penaeid shrimp, substantially shortening product shelf life. To prevent black spot formation, the shrimp industry relies mainly on sulphites and 4-hexylresorcinol, two chemical benchmarks not aligned with clean-label and organic production goals. This scoping review critically evaluates natural and biobased interventions reported for shrimp melanosis control, with the explicit aim of assessing how consistently enzyme-level inhibition evidence translates to product-level preservation outcomes, a link that, as the available literature reveals, remains largely unresolved for most candidates. Literature and patent evidence published from 1950 to April 2026 were examined by separating enzyme-level evidence, such as inhibition of shrimp polyphenol oxidase/phenoloxidase (PPO/PO) activity, from product-level evidence, such as visible melanosis suppression during chilled or iced storage. Among the reviewed interventions, many act through overlapping mechanisms, including (partial) PPO/PO suppression, quinone interception, antioxidant effects, metal interactions, and microbial control. Overall, the available studies suggest that shrimp melanosis is rarely controlled by PPO/PO inhibition alone; in practice, delivery, redox effects, matrix interactions, and broader quality preservation often contribute substantially to the final outcome. Finally, we propose an author-defined Target Candidate Profile (TCP) and Target Product Profile (TPP) that integrate mechanism, cold-chain efficacy, safety, sensory compatibility, residue burden, environmental profile, and industrial feasibility to support more rigorous prioritization of future biobased anti-melanosis candidates.
