Investigation of the potential of using different extracts of marine macroalgae as active ingredients in the formulation of edible coatings for IV gamma products resulted in a new edible coating, already patented, from Codium tomentosum extract. The AlgaeCoat project aims at demonstrating at the pilot scale the conditions for its commercial profitability, with application in apple, pear, uncontrolled atmospheres and the long conservation of whole fruit. This additive will represent a sustainable option of natural origin, which will contribute to the added value of IV range products, also increasing its internationalization potential, and reducing food waste and costs across the industry.
