VILLARREAL-FUENTES, Juan Manuel et al. Postharvest characterization of selections of Mamey Sapote (Pouteria sapota (Jacq.) H. E. Moore & Stearn) Selections from Soconusco, Chiapas. Ecosistemas y recur. agropecuarios [online]. 2015, vol.2, n.5, pp.217-224. ISSN 2007-901X.

Fruits from six selections (S) of mamey sapote were harvested in the Soconusco, Chiapas at a mature stage and ripened at room temperature (23 °C and 70 % R. H.) for 12 d. The fruits from the six selections showed maximum respiration and ethylene rates between 31 and 44 mL C02 kg-1 h-1, and 225 and 550 /µL kg-1 h-1, respectively. Fruits from selections SI and S2 kept flesh firmness for longer (≤ 20 N), lowest content of phenolic compounds (0.5-0.6 mg g-1 fresh weight) and the best color parameters (L* = 61, C* = 46 and h = 55). Soluble solids content was between 17.5 y 23 °Brix and total sugars was 122 y 196 mg g-1 at ripe stage of selections evaluated with no significant differences. We conclude the SI and S2 selections had the best postharvest characteristics.
