A detailed analysis of sunflower oil's quality necessitates a range of strict tests. These cover examining its physical properties , such as color, transparency , and weight . Furthermore, the chemical profile is critically checked, looking at parameters like free fatty acids, peroxide value – a key indicator of oxidation – and iodine value, which reflects unsaturation levels. Finally , sensory aspects, including flavor and odor, are even assessed to determine its suitability for various purposes. These combined factors provide a holistic picture of the oil's overall merit.
Refined Sunflower Oil – Detailed Scientific Findings
Recent examination of a lot of refined sunflower oil revealed notable details regarding its composition and quality. The results indicated a remarkably low level of free fatty acids, measuring at just 0.05%, illustrating excellent refining efficiency. Additionally, the peroxide value was consistently below acceptable limits, at 0.1 meq/kg, suggesting minimal oxidation and freshness . Specific fatty acid profile analysis identified a dominance of linoleic acid ( approximately 65%), oleic acid ( close to 27%) and palmitic acid (roughly 10%). Minute amounts of other fatty acids were also detected. The color, measured using the Lovibond scale, was determined to be a minimal value of 2.5 red and 1.0 yellow, confirming its characteristic clarity. Overall, the comprehensive evaluation reinforces the high purity and quality of this refined sunflower oil.
