Abstract(s)

In general, dry nuts, such as hazelnuts, almonds. chestnuts and walnuts, composition has been investigated and are well characterized. Nevertheless, other less unknown nuts, such as beech nuts have little information. Beech nuts proceed from the Fagus sylvatica L. tree, which is prevalent in central and southem Europe, and is commonly used for oil extraction. A study carried out by Obranovic et al. found that the chemical composition of beech nut oit varies significantly depending on the geographical origin. Siger et al. characterized the oit obtained from beech nut seeds, highlighting its high content in linoleic acid. However, scientific data regarding the physicochemical properties and composiHon of beech nuts are scarce. In this context. this work evaluated whether there are differences in terms of the physicochemical data and composition of the beech nut between regions, by applying a chemometric procedure.
