Abstract
Pomegranates are valuable fruits due to the high level of anthocynanins in juice and phenolic compounds responsible for antimicrobial activity of pomegranate peel. Significant amounts of phenolic acids, vitamin C and other polyphenolics are responsible for health benefits of the consumers. The objects of our study was the impact of variety on the quality of pomegranates grown in the region of Macedonia. More precisely, morphological parameters for fruits and chemical characteristics of pomegranate juice were significantly affected to the variety of pomegranates. Morphological parameters, in particular fruit weight, fruit height, equatorial and calix diameter favorited “Hicaz” variety in comparison to autochthonous “Karamustafa” variety of pomegranates. Furthermore, the pH value of fruit juice, the level of phenolic acid and percentage of glucose and fructose indicate significant differences between varieties. The quantity of anthocyanins (537 mg/L), catechins (50 mg/L) and total phenolic compounds (3367 mg/L) indicated higher quality of pomegranate juice from “Hicaz”pomegranate variety. The effect of pasteurization did not influenced significantly to the quality of pomegranate juices from both varieties.
Key words: pomegranate juices, morphological parameters, total phenolic compounds, anthocyanins, catechins
