    The objective of this thesis was to create an edible coating made of hydrocolloids (carrageenan and alginate) and essential oils to improve the preservation of York ham and reduce the need for conventional plastic packaging. The methodology involved optimizing a functional mixture applied by simple immersion to standardized samples, analyzing their characteristics over 15 days of refrigerated storage. The physical results indicated that the treatment was effective as a barrier, showing a limited moisture loss of 42.07% compared to 55.13% in the control group. This moisture retention was essential to prevent the product from exceeding 50% dehydration, thus avoiding the meat becoming irreparably tough. Regarding mechanical properties, the film showed increased firmness upon puncture as residual moisture decreased, while maintaining its structure. Microbiological analysis confirmed the final product's safety, registering a mesophilic aerobic bacterial count of 1.4x104 CFU/g and no pathogens present, strictly complying with standard NTE INEN 1338:2016. Finally, sensory evaluation showed an overall conformity level of 90%, highlighting a preference for flavor and aroma compared to the uncoated sample. It is concluded that the developed coating represents a viable technological option that guarantees the physical, sanitary, and organoleptic stability of the meat product.
