Analysis of Secondary Metabolites in Peel and Pulps of Local Apple Varieties of Belluno Region as Valuable Health Promoting Products

Apples (Malus domestica Borkh) are cultivated worldwide and are the most widely grown species of the genus Malus. This study aims to analyze the secondary metabolites in the peels and pulps of fifteen local apple varieties of the Belluno region. The research will focus on the analysis of secondary metabolites in apple samples like chlorogenic acids, proanthocyanidins, flavonoids, and chalcone, by high-performance liquid chromatography (HPLC) and mass spectrometry (LC-DAD-MS). These results showed Local apple varieties of Belluno region have valuable amounts of polyphenols among different apple cultivars that have been studied, which have potential as a source of natural food additives due to their high content of bioactive compounds.
