Refined Sunflower Oil – Detailed Lab Findings
Recent testing of a batch of refined sunflower Dar es Salaam Sunflower Oil Supplier oil revealed interesting details regarding its composition and quality. The findings indicated a remarkably low level of free fatty acids, measuring at just 0.05%, demonstrating excellent refining efficiency. Additionally, the peroxide value was consistently below acceptable limits, at 0.1 meq/kg, suggesting minimal oxidation and stability . Specific fatty acid profile analysis identified a dominance of linoleic acid ( roughly 65%), oleic acid ( close to 27%) and palmitic acid ( around 10%). Minute amounts of other fatty acids were also detected. The color, measured using the Lovibond scale, was determined to be a low value of 2.5 red and 1.0 yellow, confirming its characteristic clarity. Overall, the scientific evaluation reinforces the high purity and quality of this refined sunflower oil.
