摘要

In this study, physico-chemical properties, fatty acid composition, and tocopherol contents of several walnut kernel oils obtained through cold-press and Soxhlet extractions were investigated. The acidity, peroxide, and unsaponifiable matter of oil samples extracted in the Soxhlet system were found higher. Total phenol contents of the oils obtained in cold press and Soxhlet extraction systems were 121.9 mg GAE/100g (Kaman-2) and 154.6 mg GAE/ 100g (Buyukoba), and between 135.9 mg GAE/100g (Kaman-2) and 163.8 mg GAE/100g (Buyukoba), respectively (p < 0.05). In addition, antioxidant activity valuesof walnut oils obtained in cold press and Soxhlet extractions varied between 17.3% (Kaman-2) and 19.7% (Kaman-5), and between 18.4% (Kaman-2) and 23.8% (Bueyuekoba), respectively (p < 0.05). Linoleic acid contents of the oil samples extracted in cold-press varied between 55.19% (Kaman-5) and 56.71% (Kaman-2), while that extracted from Soxhlet extraction system varied between 54.47% (Kaman-2) and 55.93% (Buyukoba). y-Tocopherol contents of walnut oils extracted in cold press and Soxhlet extraction ranged between 9.41 mg/100g (Bueyuekoba) and 10.83 mg/100g (Kaman-2), and 8.76 mg/100g (Kaman-5) and 9.33 mg/100g (Kaman-2), respectively, and were statistically significant (p < 0.05).
