Özet
The aim of the present study was to determine the chemical, fatty acid, and mineral compositions of 10 types of walnut (Juglans regia L.) selected during 2010 and 2012 from the Yesilli (Mardin) district located in the Southeast Anatolia Region of Turkey. The average values of total oil, protein, carbohydrate, and energy were 61.08-64.8%, 14.85-20.26%, 13.77-17.16%, and 686.2-710.0 Kcal, respectively. In terms of mineral composition, K was the major mineral in all samples, ranging from 534.3 to 778.6 mg 100 g(-1). P was the next most abundant mineral, ranging from 346.0 to 584.8 mg 100 g(-1), followed by Ca and Mg, ranging from 100.9 to 233.9 mg 100 g(-1) and from 117.8 to 181.4 mg 100 g(-1) respectively. Saturated fatty acids levels were lower than those of other types of fatty acids. Of the identified fatty acids, linoleic acid (50.24-60.60%) was the predominant fatty acid, followed by oleic acid (20.70-28.33%) and linolenic acid (10.93-15.04%) in all types of walnut. Other fatty acids were present at trace levels.
