Comprehensive identification of polyphenols in different hazelnut products
Abstract
The aim of this study was to identify the polyphenolic profiles of hazelnut products (natural hazelnut, roasted hazelnut, hazelnut skin, and cold press hazelnut oil). <BR />Within the scope of the study, polyphenolic profiles of hazelnut products were analysed tentatively. Q-Exactive LC/MS/MS (orbitrap) was used to tentatively identify the new polyphenolic compounds in hazelnut products and 32 compounds were detected, of which 16 were identified for first time in hazelnut products. The majority of polyphenols were detected in hazelnut skin, while epicatechingallate was the only phenolic compound detected in hazelnut oil. As a result, the present study suggests that hazelnut skin is a good source of polyphenols and can be used as source of functional ingredients.
