AbstractThe quality of fresh Padus avium fruits from there maturity stages was analyzed. Conducted analysis included yield of fruit flesh and stone, physicochemical parameters, antioxidant properties and color. Fruit flesh yield and L-ascorbic acid content increased between first and second week of fruit harvest, and decreased in the following ripening period. The content of dry weight, extract, reducing sugars, total polyphenols, total flavonoids and acidity of fruits increased constantly with fruits maturation, while antioxidant activity after two-fold increase between first and second harvest remained constant between second and third harvest. Color parameters of fruits differed significantly between maturity stages, however color difference ΔE was at level indicating no visual difference for the spectator. For commercial use fruits from middle maturity are advised, since they are characterized by lowest share of stone and satisfactory antioxidant properties and acidity.
