Production of juice from berry fruits generates large number of byproducts, mostly in the form of pomace and seeds. The valorization of berry seeds to obtain oil is particularly important, due to its chemical composition and nutritional value. However, as a niche products, cold-pressed berry seed oils are sold at high prices, mainly by e-commerce, where the control of authenticity is rare. It is worth noting that these oils are susceptible to adulteration with lower-quality oils, which can have a detrimental effect on their nutritional value, safety, and sensory properties.
The aim of this study was to use the entire profiles of melting phase transition and FTIR spectra of selected berry seed oils (raspberry, strawberry, blackcurrant) for authentication purposes by applying the chemometrics.
