Some physico-chemical properties, fatty acid compositions, macro-micro minerals and sterol contents of two variety tigernut tubers and oils harvested from East Mediterranean region

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.

Physicochemical properties of tigernut ( Cyperus esculentus ) tuber starch and its application in steamed bread

“…

Tigernut (Cyperus esculentus L.), native to northeast Africa, belongs to the sedge family (Babiker et al, 2021). It is an important multipurpose crop, its stems and leaves can be used as green feed and knitting materials, and the roots with a fragrant smell are a potential source of essential oils (Duman, 2019;Lasekan, 2013;Ozcan et al, 2021). Tigernut tubers are rich in lipids, proteins, starches, dietary fibers, and vitamins, which are usually applied to develop edible oil, plant milk, and snack food (Clemente-Villalba et al, 2021;Oluwajuyitan & Ijarotimi, 2019).The extraction and physicochemical characterization of tigernut tuber oil have been widely reported (Aljuhaimi, Ghafoor, et al, 2018; Aljuhaimi, Simsek, & Ozcan, 2018).

New Advances in the Phenolic Composition of Tiger Nut (Cyperus esculentus L.) by-Products

“…They also could be named pinellic acid isomers, according to Ruan et al (2019), who described them in Pluchea indica aerial parts [26]. Peaks 37-40 and 42-45 were identified as fatty acids, linolenic, myristic, palmitoleic, linoleic, palmitic, oleic, heptadecanoic, and stearic, according to several authors that found them in tiger nut oil [27][28][29]. Hydroxyoleic acid isomers (peaks 31-33, 35) and dihydroxyoleic acids isomers (peaks [23][24][25][26], derived from oleic acid, have also been found.…”

The physicochemical analysis and health benefits of fresh and branded honey produced in delta state, Nigeria

“…The free acidity in honey is present due to polyphenol, ascorbic acid, and amino groups. 24 The fermentation process of sugar into organic acids results in an increase in the honey acidity degeneration. The free acidity value of FHs honey samples (16.8 ± 4.97) and BHs honey samples (19.0 ± 2.34) samples (Table 1) were within the International limits of not more than 50 meq/kg.…”
