Biochemical content of hazelnut (Corylus avellana L.) cultivars from West Black Sea Region of Turkey.

Abstract

Twelve hazelnut cultivars taken from Bolu-Akcakoca, West Black Sea Region of Turkey, were evaluated in terms of bioactive properties such as fat and fatty acid composition, protein and amino acid, water-soluble and water-insoluble vitamins, ash and mineral content at 2 consecutive years. Considerable differences were observed among cultivars for all properties (P ≤ 0.05) with the exception of palmitoleic acid, leucine and threonine content (P ≥ 0.05). In all cultivars, fat was the predominant component (56.45–64.11 %) followed by oleic acid (80.59–85.64 %), glutamic acid (2.342– 3.543 g 100 g–1), arginin (1.310–2.366 g 100 g–1), α-tocopherol (19.24–378.80 mg 100 g–1), ascorbic acid (1.430–3.207 mg 100 g–1), potassium contents (560.20–893.90 mg 100 g–1).
