The objectives of this study are to present some data regarding some fruit’s quality parameters and the customers’ perception on few pawpaw hybrid genotypes in different ripening stages. Asimina triloba hybrids were cultivated in the experimental field established at the Faculty of Horticulture, within the University of Agronomic Sciences and Veterinary Medicine of Bucharest, in an organic orchard and all the determinations and analyses were made at the Research Center for the Study of Food Quality and Agricultural Products laboratories. The pawpaw fruits were harvested starting with the end of August – early September and ended up at mid-October. After harvest, the fruits were preserved in cold storage, at 1-2°C and 90-95% relative humidity. Fruits quality analyses were made in two different ripening stages: at harvest and after three weeks cold storage. Different fruit characteristics were measured and evaluated: fruit size and weight, soluble solids (SSC), glucose and fructose content, pulp color etc. The results showed important differences between the two ripening stages of pawpaw fruits. The sensorial analyses were organized with different age, gender and origin consumers, chosen to taste fresh fruit or three weeks cold stored pawpaw fruits. In the tasting questionnaire costumers evaluated, by using 1 to 5 grades, fruits size, shape, pulp color, taste and flavor. The obtained results showed that the fresh harvested fruits were easily accepted by the all consumers, while the overripen fruits were appreciated only by some of them. During cold storage the taste of the pawpaw fruit changes. While fresh picked fruits have an exotic taste similar to mango, pineapple and banana, during storage, the taste changes into caramel or even coffee-like flavour. In addition to the exotic taste and aroma, Asimina fruits are highly valued for their high content of vitamin A and C, mineral elements, especially Ca, Fe, Mg, Mn and amino acids. All these inner properties of Asimina fruits have been highly appreciated by consumers.
