          Abstract

          Se evaluó el almacenamiento de frutos de zapote mamey en películas plásticas para determinar su efecto en algunos cambios físicos y químicos en postcosecha. Se colectaron frutos en madurez fisiológica y se almacenaron en tres películas plásticas: Ziploc®, KleenPack® y PEAKfresh®; adicionalmente se colocaron frutos sin ninguna película plástica. Se evaluó la pérdida de peso, cambios de color (luminosidad, matiz y cromaticidad), firmeza, acidez titulable, pH, azúcares, carotenoides y fenoles totales. Los frutos testigo mostraron pérdida de peso diario de 1.9% y maduraron ocho días después de la cosecha. Los azúcares y sólidos solubles se incrementaron durante la maduración en forma significativa; la acidez y pH no mostraron cambios significativos durante la maduración. La luminosidad y el ángulo de matiz disminuyeron durante la maduración y no se detectaron cambios significativos en la cromaticidad. Tampoco se detectaron cambios importantes en la concentración de fenoles y carotenoides totales. La utilización de películas plásticas retrasó todos los cambios observados durante la maduración de los frutos de zapote mamey, sin embargo, la película plástica KleenPack®, mostró los mejores resultados, al retrasar la maduración sin afectar significativamente la calidad de los frutos. Los resultados indicaron que es necesaria la utilización de barreras para evitar la rápida maduración y pérdida de peso en los frutos de zapote mamey en postcosecha.

          The storage of sapote mamey fruits in plastic films was evaluated to determine the effect on some physical and chemical changes during postharvest. Sapote mamey fruits were collected at physiological maturity and stored in three plastic films: Ziploc®, KleenPack® and PEAKfresh®. Additionally, fruits without plastic films were used as control. Weight losses, color changes (brightness, chroma and hue), acidity tritable, pH, sugars, carotenoids and total phenol were evaluated. Control fruits showed daily weight losses of 1.9% and ripened 8 days after harvest. The sugars and soluble solids increased during ripening, but the titratable acidity and pH did not show significant changes. Brightness and hue angle diminished and there were no changes in chroma. There were no important changes in phenols and total carotenoids concentrations. The use of plastic films delayed all changes observed during ripening of sapote mamey fruits. The plastic film KleenPack® showed the best results, retarding ripening without affecting the fruit quality. Results indicated that it is necessary to use barriers to avoid quick ripening and weight losses in sapote mamey fruits in postharvest.
