Absztrakt (kivonat)
Quince (Cydonia oblonga Miller) is a commonly cultivated plant throughout the world, known for centuries for its valuable nutritional and curative properties. Although quince fruits are extremely aromatic, due to their high hardness and sour, astringent [10] and bitter taste, they are not suitable for direct consumption in unprocessed form. However, they are an important raw material in fruit processing, for example, in the production of jams, jellies and juices. Quince fruits fall into the category of temperate fruits, so their shelf life can be predicted. Considering that technological processing affects not only the organoleptic properties and shelf life, but also the functional properties of the fruits, For this study, 20 fruits from 4 quince varieties (Bereczki_RO; Champion_HU; De Portugalia_TR; Constantinopol_RO) that were purchased from the supermarket, in 2024, were analyzed, the fruits were studied from a biometric and qualitative point of view, tracking the following parameters: large diameter (mm), small diameter (mm), height (mm), weight (g), soluble dry matter (0Brix), sugar percentage (%) and fruit firmness. From the results obtained for the physical (biometric)-chemical parameters, the following results can be observed: for the Bereczki_RO quinces: the average of the large diameter values is 80.42 mm, the highest value was recorded by the Constantinopol_RO variety, with a value of 88.65 mm, with an average of the experiment of 82.48 mm. Regarding the soluble dry matter (0Brix)% and the percentage of sugars, it can be observed that the Bereczki_RO variety recorded the highest value for these parameters, these being 14.01(0Brix), respectively 12.39%.
