This research on Yellow sugar and Honey tuber varieties tigernut tubers' oils physico-chemical properties were investigated to collected from Adana province in Turkey. The 1000 seed weight, width, length, moisture, ash and ascorbic acid values of yellow sugar and honey wax tubers were established as 343,496 and 327,524 g, 7.61 and 8.76 mm, 17.07 and 15.23 mm, 6.41 and 6.45%, 1.19 and 1.38% and 67.34 and 58.81 mg/kg, respectively. Free fatty acidity, peroxide values, refractive index, density, iodine number, total sterol, saponifiable matter, unsaponifiable matter, mineral values of yellow sugar and honey tuber tigernut oils were determined. The palmitic, stearic, oleic and linoleic acid contents of yellow sugar and honey tuber oils were determined as 13.02 and 12.76, 3.92 and 3.94, 69.34 and 69.91, and 11.93 and 11.80%, respectively. Campesterol, sitigmasterol and beta-sitosterol contents of yellow sugar and honey tuber tigernut oils were determined. According to results, chufa tubers have high oil, oleic acid, sterol and some minerals suggest that these tubers may be very useful effect on human health and tuber oils can be use in the vegatable oil industry.
