Abstract
Physical and chemical characteristics of chufa oil extracted from chufa tubers were determined. Chufa, originally a weed in tropical and Mediterranean regions, is cultivated in Korea. n-Hexane was chosen as a solvent for extraction of neutral lipids. The extraction yield of crude lipids using n-hexane was 19.96% with a neutral lipid content of 94.6%. The extraction solvents n-hexane, diethyl ether, and chloroform/methanol affected the extraction yield but did not affect the acid, peroxide, and saponification values, and the refractive index of chufa oil. The iodine value and color of chufa oil were affected. The major fatty acids of chufa oil were oleic acid (64.4-66.1%), palmitic acid (15.2-16.0%), and linoleic acid (14.8-15.9%). The characteristics of chufa oil obtained from chufa tubers grown in Korea were not different from those in other regions.
