ESPINOSA-ZARAGOZA, Saúl et al. Quality features of zapote mamey (Pouteria sapota jacq.) selected in Alpoyeca, Guerrero, Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.4, pp.953-959. ISSN 2007-0934.

The quality characteristics and postharvest were measured in fruit of 11 materials mamey (Cid, Dario Diaz, Genaro, Juanito, Pardo I, Pardo II, Pardo III, Gift, Laughing and Red) in the region of Alpoyeca, Guerrero, Mexico. The fruits were harvested at physiological maturity, and were measured: total weight, proportion of pulp, peel and seed shape index by length/diameter ratio. They are stored at 20±2 °C for 7 d color, firmness and total sugar concentration in the pulp, and weight loss was measured. Cid, Dario Diaz, Genaro, Pardo II, Risueño and Red produced fruits weighing less than 500 g. Risueño had the highest proportion of pulp and lowest seed and zest. Diaz Pardo II, III and Gift Pardo had deep orange-red. Firmness to maturity of consumption varied between 41.3 N in the selection Risueño and 1.4 N in the red. The highest concentration of sugars Red (42.8%) and the lowest Pardo I (10.9%) had. Shelf life was of 5 matching d with maturity of consumption, but the extension to 7 d resulted in overripe fruit.
