Extraction And Characterirization Of Sunflower Crude Oil.

Abstract

The oil samples used for this work were obtained from sunflower seeds. The seeds was prepared, dried, dehulled, conditioned and flaked. The oil was extracted by solvent extraction. The oil sample was investigated for their physico-chemical parameters which were specific gravity, refractive index, colour, flash, fire smoke, soft and turbidity points. There values were 0.923± 0.016, 1.475±0.002, 18.00 units,339.00±2.20 o C, 342±1.20 o C, 235.00±1.75 o C, 42.00±1.108.00±0.20, 42.00±1.10, respectively. Other were free fatty acid, acid value, saponification value, peroxide value iodine value and yield, the values were 1.40±0.007%, 3.09±0.24%,197.43±0.42mgKOH/goil,12.6±2.20Meq0 2/ kg, 131.60±0.71WIJ, 41.3±2.12% respectively. The qualitative determination of the fatty acid composition was carried out by methylation and application of Gas chromatography. The percentage yield which was 41.3% makes it a good source of oil. The free fatty acid (1.40%), peroxide (12.6meg KOH goil/), confirm that the oil can be processed into edible vegetable oil. The high level of unsaturated fatty acids (linoleic and oleic acids) and low level of saturated fatty acids(Myristic, palmitic and stearic acids) makes the oil a liquid oil. Finally, the oil, if refined and consumed, it will be a good source of essential fatty acid needed in the body.

Biorefinery methods for extraction of oil and protein from rubber seed

“…Therefore, the moisture content must be substantially lowered (≤ 7%) before rubber seeds can be safely stored (Ebewele et al 2010 ). Rubber seeds are also rich in oil; the oil content in dried kernels is 48.78% (Table 1 ), which is high compared to seeds such as flax, sunflower, and rapeseed (Abitogun et al 2012 ; Li et al 2014 ).…”

Biorefinery of Rubber Seed Kernels for Comprehensive Utilisation

“…Through solvent extraction (Fig. 7a), the oil yield of rubber seed is higher than most oilseeds, including axseed, palm fruit (Tan et al, 2017), sun ower seed (Abitogun et al, 2012), sesame (Elkhaleefa and Shigidi, 2015) and rapeseed (Li et al, 2014). As shown in Fig.…”

Effect of minimal neutralization at optimal conditions on minor components and oxidation stability of sunflower oil

“…Sunflower is divided into two groups; the oilseed and non-oilseed. The chemical content of the sunflower oil depends on the genetic, environmental situations and the maturity of the seed (Baydar & Erbas, 2005;Abitogun et al, 2008;De Oliveira Filho & Egea, 2021). The quality and composition of sunflower seed that adapted to high temperature and limited water surrounding is impacted by maturity of the seed, growing conditions and storage parameters.…”
