Lipids and minerals of the most represented hazelnut varieties cultivated in Croatia

The Croatian autochthonous hazelnut variety Istarski Duguljasti and two introduced varieties Romische Zellernuss and Hallesche Riesen were characterized with respect to their fatty acid composition as well as their squalene, tocopherols and minerals content. Oleic acid was the most abundant fatty acid ranging from 78.13% in Istarski Duguljasti to 82.98% in Romische Zellernuss, followed by linoleic acid, which showed the largest variation in the content between varieties. α-, β- and γ-tocopherol were identified in all three varieties. The level of squalene ranged from 201.2 to 243.6 mg/kg and potassium was the most abundant mineral varying between 6.81-7.77 g/kg. Obtained results highlight the nutritional characteristics of hazelnut and the influence of hazelnut variety on studied nutrients.
