Abstract: Quality postharvest of three cultivated species of the Northeast Region of Brazil was evaluated after receiving ionising radiation. Cashew peduncles (Anacardium occidentale L. var. Nanum) stored for 14 days under 6.5°C had presented best results in the sensorial analyses for external appearance, flavour and aroma when irradiated with 1 kGy. Sapodillas (Manilkara sapodilla (L) Van Roy en) irradiated with doses of 300, 600 and 900 Gy have not displayed harmed sensorial qualities when stored under 20°C during 12 days. Doses up to 800 Gy had not harmed the external and internal appearance of mangaba (Hancornia speciosa Gomes) after stored for fortnight under 13°C. Values of Total Soluble Solids, Total Titratable Acidity, pH and solid/acidity ratio have not been affected significantly by the different doses applied to the three studied species. Amount of ascorbic acid was lower in the irradiated fruits for the species A. occidentale L. var. Nanum and H. speciosa Gomes.

Keywords: ionising radiation; fruit storage; fruit conservation; postharvest quality; regional fruits; sensorial analyses; fruit quality; Brazil; ascorbic acid; low radiation; total soluble solids; total titratable acidity; pH.
