RAMOS-RAMIREZ, F. X. et al. Storage of sapote mamey fruits [Pouteria sapota (Jacq.) H. E. Moore & Stearn] in modified environment. Rev. Chapingo Ser.Hortic [online]. 2009, vol.15, n.1, pp.17-23. ISSN 2007-4034.

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.
