Abstract
Abstract 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 β-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.
Highlights
Tigernut (Cperus esculentus L.) widely cultivates in some countries around the world for example Greece, Italy, Turkey, Israel and West Africa countries (Temple et al, 1989; Eteshola & Oraedu, 1996)
The aim of this researh is to determine from wide angle some physical properties, fatty acid composition, sterol contents and mineral contents of chufa tuber and oils harvested from East Mediterranean region in Turkey
Samples variety were identified as Sarı şeker and Bal yumru varieties by Adana Eastern Mediterranean Agricultural Research Institute
Summary
Tigernut (Cperus esculentus L.) widely cultivates in some countries around the world for example Greece, Italy, Turkey, Israel and West Africa countries (Temple et al, 1989; Eteshola & Oraedu, 1996). Tigernut oils have contetnt rich palmitic and oleic acids in terms of fatty acid composition (Eteshola & Oraedu, 1996; Yoon, 2015). Tiger nut tubers have been used in the field of health against various diseases such as aphrodisiac, carminative, diuretic (Chopra et al, 1986). The aim of this researh is to determine from wide angle some physical properties, fatty acid composition, sterol contents and mineral contents of chufa tuber and oils harvested from East Mediterranean region in Turkey
