A detailed evaluation of sunflower oil's quality necessitates a series of strict tests. These cover examining its physical characteristics , such as color, clarity , and density . Furthermore, the fatty acid 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. In conclusion, sensory aspects, including flavor and odor, are too assessed to determine its suitability for various applications . These combined factors provide a holistic understanding of the oil's overall merit.
Refined Sunflower Oil – Detailed Lab Findings
Recent testing of a lot of refined sunflower oil revealed significant details regarding its composition and quality. The data indicated a remarkably low level of free fatty acids, measuring at just 0.05%, showing excellent refining efficiency. Additionally, the peroxide value was consistently below acceptable limits, at 0.1 meq/kg, suggesting minimal oxidation and longevity. Specific fatty acid profile analysis identified a dominance of linoleic acid ( roughly 65%), oleic acid (approximately 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 laboratory evaluation reinforces the high purity and quality of this refined sunflower oil.
