Fruit of the Stenocereus genus have good acceptance and high potential in the fresh fruit market. However, their use is limited to regional production areas due to they are highly perishable and the postharvest behavior has not been studied. The objective of the work was to characterize morphological, physiological, physical, and chemically, red and orange fruit of Stenocereus pruinosus, and red and white fruit of Stenocereus stellatus in postharvest. Storage during 10d at 24°C was carried out and shelf life was estimated in six days. Respiration rate suggested non-climacteric behavior. Color, acidity, pH, soluble phenols content, and betalains content distinguished fruit. These variables, besides total soluble solids, remained without significant changes throughout the storage period, but weight loss, firmness, and total sugar content experimented modification. Antioxidant activity was highest in red fruit.
