LC-(HESI)-MS/MS study of polyphenolic profile of peel of ‘Bobovac’ - a traditional apple cultivar from Croatia

There has been an increasing interest in the food industry and a growing trend in consumer preferences for natural antioxidant sources. Apple by-products, especially apple peel, are an excellent source of natural antioxidants, such as catechins, procyanidins, caffeic acid, phloridzin, phloretin glycosides, quercetin glycosides, and chlorogenic acid, among others. It has been suggested that a valuable food ingredient can be obtained by using the apple peel and the addition of such ingredient in various food products can promote human health. Traditional apple varieties grown in local areas have so far been largely unexplored considering polyphenolic profile. Moreover, they might represent an important source of bioactive compounds and constitute the basis for further breeding. Accordingly, this study is aimed at determination and quantification of the apple peel polyphenolic profile by LC- (SESI)- MS/MS. Results are confirming that the peel of traditional apple cultivar ‘Bobovac’ is rich in polyphenols. More than 20 individual polyphenols were detected, while procyanidins and chlorogenic acid were the most abundant. Due to such polyphenols diversity, it is important to preserve traditional apple varieties as a source of genetic variability as well as a factor of biodiversity of the area where they grow.
