Abstract
The aim of the present study was to determine the physico-chemical and bioactive properties of mandarin, orange and lemon seed oils. Viscosity values of orange seed oils ranged from 0.053 to 0.205 Pa · S. Peroxide value, acidity, saponification and Iodine values of mandarin, orange and lemon seed oils changed between 7.80 and 20.94 meq O2/kg, 2.81 and 7.12%, 192.54 and 195.39 mg KOH/g, 102.39 and 110.45; between 9.33 and 14.01 meq O2/Kg, 2.52 and 7.32%, 195.38 and 203.79 mg KOH/g, 97.77 and 102.43 and between 9.63 to 22.25 meq O2/kg, 3.83 to 4.83%, 194.08 to 195.31 mg KOH/g and 102.39 and 110.45, respectively. Palmitic acid contents of mandarin seed oils changed between 23.54 and 25.29%. While oleic acid contents of mandarin varieties changed between 22.48 and 23.85%, linoleic acid contents of seed oils of mandarin varieties were found between 41.86 and 42.81%. α‑Tocopherol contents of mandarin, orange and lemon seed oils belonging to varieties were found between 320.6 and 503.1 mg/kg, 203.20 to 668.00 mg/kg, 164.980 and 343.40 mg/kg, respectively. The oils extracted from mandarin, orange and lemon seeds are a rich source of essential fatty acids and tocopherol, and are of high potential for being used for nutritional and industrial usages.
