Sapodilla fruits were harvested manually in Culiacan, Mexico,in June 1997, sorted and then stored under marketing conditions (20 deg C, 85% RH) for 6 days. Quality evaluations were made every 48 h. Respiration rate and ethylene evolution were measured daily for 9 days. Fruits reached the climacteric peak (27 ml CO2 kg-1 h-1) after 6 days under marketing conditions. The ethylene peak preceded the rise in respiration by one day with maximum production of 1.7 micro l kg-1 h-1. At harvest, the fruits had 13.2 deg Brix, 0.24% titratable acidity and a firmness of 64.6 N. Fruit weight loss after 6 days at 20 deg C reached 5.1%, while firmness dropped to 1.9 N; on the other hand, soluble solids content increased to 25.8 deg Brix. Titratable acidity didn't show any significant changes during marketing. Pulp colour ranged from white-cream at harvest to light orange after 6 days at 20 deg C.
