Sažetak
Fruit skin color plays a major role in quality assessment of food, significantly determining consumer`s choice. Color of sour cherries depends on anthocyanins which are phenolic compounds (flavonoids) present in high amounts in fruits. The aim of this study was to determine possible relation between polyphenols (total phenols and anthocyanins) and color parameters of fruit skin of sour cherries. The plant material used in this study was twenty two sour cherry genotypes from orchard of Agrocultural Institute Osijek. Color parameters (L*, a*, b* and h) of fruit skin were determined according to CIELAB method with colorimeter CR-400 on thirty fruits in four replicates per genotype. Polyphenols and anthocyanins were determined spectrophotometrically, after ultrasound extraction of grounded defrozen tissue with acidified methanol. Total polyphenols content varied from 462.65 to 1048.93 mg/100g of fresh weight, while total anthocyanins ranged from 160.14 to 495.55 mg/100g of fresh weight. Significant positive correlation was found between polyphenols and anthocyanins content. Investigated sour cherry genotypes showed differences in color parameters as follows: lightness (L*) varied from 25.54 to 27.76, a* varied from 8.56 to 15.24, b* from 1.44 to 3.78 and hue angle (h) from 9.38 to 13.92. Total polyphenols and anthocyanins content had significant negative correlation with color parameters (L* and h).
