Preventing melanosis remains a critical factor in maintaining the quality and market value of crustaceans. Although sulfite treatments have been the most widely used solution for years, regulatory requirements, consumer demands, and the search for safer products are driving the adoption of sulfite-free alternatives.
PH7’s Crustaxyl® , based on 4-hexylresorcinol, is a widely recognized line of solutions for controlling melanosis that helps maintain product quality without the use of sulfites.
🔬 A sulfite-free alternative for controlling melanosis
Crustaxyl® works by specifically inhibiting polyphenol oxidase (PPO), the enzyme responsible for the development of melanosis. Its effectiveness has been extensively demonstrated in crustaceans, yielding results comparable to those of traditional treatments with sodium metabisulfite.
In addition, it offers significant additional benefits:
✔ Sulfite-free and with no release of SO₂
✔ No allergenic risk associated with sulfites
✔ No impact on the product’s taste, smell, or texture
✔ Better preservation of the seafood’s appearance and visual quality
✔ Greater safety for workers during handling
A solution tailored to the demands of today’s market
More and more importers, distributors, and consumers are valuing products with cleaner labels and fewer controversial additives. Crustaxyl® enables the development of sulfite-free marketing strategies, facilitating access to demanding markets and reinforcing the perception of quality in the final product.
Quality, Safety, and Profitability for the Seafood Industry
Thanks to its high efficacy at low doses and its easy integration into existing processes, Crustaxyl® helps reduce losses due to melanosis, improve retail presentation, and optimize the product’s commercial value throughout its shelf life.
