dc.description.abstractThis work describes the development of a sustainable and natural coating solution based on iota-carrageenan and rosemary extract intended to preserve cooked ham through dipping. Upon comparing the physical and microbial load changes between this solution and the traditional plastic wrap along 15 consecutive days, the results showed that in terms of microbial load the samples treated with the developed solution had a lower microbial count. Furthermore, only slight changes in moisture loss and hardness were observed between samples using the two tested preservation strategies. Colour analysis revealed that dipped samples presented reduced lightness, with a tendency to avoid shifting to a blue tone over the 15-days of storage. This work indicates that natural polymers combined with natural antimicrobials and antioxidants can be employed to reduce the dependence on synthetic polymers and offer feasible solutions to be applied at an industrial level.
