Biochemical Content of Hazelnut (Corylus avellana L.) Cultivars from West Black Sea Region of Turkey

摘要

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)), alpha-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)).
