Abstract
Celosia argentea is annual herbaceous widely used as leafy vegetable in Côte d’Ivoire. In this study, physicochemical and nutritive analysis of this plant seed oil was performed in order to explore its potential applications. Physicochemical properties of extracted oil were as follow: specific gravity (0.92 ± 0.01), refractive index (1.47 ± 0.00), colour lovibond (20.2 ± 0.00), viscosity at 20°C (53.08 ± 0.28 mPas), cloud point (- 2.3 ± 0.00°C) acid value (4.68 ± 1.62 mg KOH/g), peroxide value (10.33 ± 0.58 meq O2/kg), iodine value (124.08 ± 1.22 g I2/100g), saponification value (170.17 ± 1.62 mg KOH/g). Biochemical and nutritive analysis have revealed the following assets: impurities (0.016 ± 0.00%), unsaponifiable matter (1.47 ± 0.21%), phosphorus (0.10 ± 0.00 mg/g), vitamin A (0.52 ± 0.01 mg/g) and vitamin E (0.12 ± 0.01 mg/g). Fatty acids profile of C. argentea seed oil highlighted linoleic acids as major fatty acid with amount of 49.94 ± 0.01%. All these interesting characteristics should arouse attention for the usage of C. argentea seed oil in food and pharmaceutical industries.
