Postharvest physiology of sapodilla (Achras sapota L.) fruits during marketing conditions.

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.
