This work had as an objective to evaluate the quality of yellow passion fruit juice (Passiflora edulis Sims. f. flavicarpa Degener) in different harvest points and after complete ripening in a storage chamber, intended for natural consumption or sales of derived products. We determined the levels of titratable acidity, ascorbic acidy, soluble solids, reducer and non-reducer sugars and pH value. The averages were compared regarding confidence intervals with a 5% significance and 10 % deviation around the sampling average of infinite population. The results showed that an adequate harvest point of the yellow passion fruits from the winter season was identified when at least 30.7% of the peel surface was yellowish. At this point they presented appropriated chemical characteristics for consumption in natura or to support the physiological ripening process during storage.
