Festival) is a very delicate fruit, non-climateric and its shelf life is very short, so it requires un innovative storage methods to prolong its shelf life. Edible coatings are used for food preservation, forming a barrier against moisture. The objective of this work was to take advantage of the agro-industrial residues such as the stalk and the peel of the sour prickly pear (Opuntia joconostle) to elaborate an edible coating an apply it onto strawberry. The mucilage present in the stalk and in the shell of the sour prickly pear was separated to prepare the covering solutions (eight treatments) and the control, submerging the strawberry. They were stored for 12 days at two temperatures (5 °C and 22 °C) and the physicochemical parameters (total soluble solids, titratable acidity, pH and weight loss) and sensory attributes of the fruit were monitored. The mucilage coating solution presented a pH 3.60 - 3.98, with a viscosity of 18 - 29.33 cP, a significant difference (P<0.05) between them was observed. The physicochemical characterization of the fruit showed a significant reduction of the parameters evaluated with respect to the control. Most of the changes were observed between days 4 and 8. Sensory evaluation did not significantly influence (P>0.05) the evaluated attributes. The results obtained in this study show that this coating based on stalk and sour prickly pear has a great potential as it does not affect the sensory characteristics of the fruit. 2020 artículo científico 1665-0204 https://www.redalyc.org/articulo.oa?id=81363356007 https://www.redalyc.org/journal/813/81363356007/ https://www.redalyc.org/journal/813/81363356007/html/ https://www.redalyc.org/journal/813/81363356007/81363356007.epub https://www.redalyc.org/journal/813/81363356007/movil en http://www.redalyc.org/revista.oa?id=813 Revista Iberoamericana de Tecnología Postcosecha application/pdf Asociación Iberoamericana de Tecnología Postcosecha, S.C.
