Evaluation of Quality and Physicochemical Properties of Castor Oil in Eastern Azarbaijan Areas

The numerous application of castor oil in order to extraordinary physicochemical properties in pharmaceutical, chemical, hygienic, cosmetics, biodiesel industries and nowadays in food science was resulted that was carry out copious research on it. In this research was investigation quality, oil content and physicochemical properties of castor oil in Eastern Azarbaijan area’s. in analysied samples oil content were (%35-52), moisture content (%0.3-0.7), refractive index (1.404-1.42), chlorophyll content (0.17-0.39 mg Pheophytin/kg Oil), acid value (0.2-0.9 mg NaOH/g Oil), peroxide value (0-0.012 meq O2/kg Oil), soponification value (167-178.5 mg KOH/g Oil) and iodine value (75-86 g I2/100 g Oil). The results of the study revealed a significant difference (p<0.05) of oil content, moisture and chlorophyll content, acid value, soponification value and iodine value but There was no significant difference (p>0.05) among of samples refractive index and peroxide value. Content oil of Marand Area’s had most Percentage. This is the first detailed report on the oil physicochemical properties and oil content of castor beans from Eastern Azarbaijan different area’s.
