Aplicación de un recubrimiento comestible a base de mucílago de nopal (opuntia ficus-indica) y aceite esencial de matico (buddleja globosa) para la conservación de la mora de castilla (rubus glaucus).

The purpose of this research project was to evaluate the application of an edible coating based on cactus mucilage (Opuntia ficus-indica) and matico (Buddleja globosa) essential oil for the conservation of blackberry (Rubus glaucus). To carry out the study, an A x B factorial design was established to determine the optimal concentrations of nopal mucilage and matico essential oil; 86% of cactus mucilage and 10% of matico oil were fixed, along with 0.10% of pectin. Additionally, 10% glycerol, 1% carboxymethylcellulose, 0.10% tween 80 were included as a plasticizer, and the formulation was completed with 3.8% distilled water. When evaluating the physicochemical parameters after 15 days, treatment 1 stood out the most, yielding the following results: weight loss 5.36%, a concentration of soluble solids of 13.7% degrees Brix, a pH of 3, 02, a titratable acidity with a value of 2.12%, with a maturity index of 6, in addition to a visual color scored at 6, finally this treatment presented molds after 15 days. Therefore, the Edible Coating is a good alternative and opportunity for farmers as well as merchants who work with this highly perishable fruit; The adoption of this technique has the potential to provide notable advantages in terms of preserving and improving the quality of the final product.
