A thorough evaluation of sunflower oil's quality necessitates a range of strict tests. These include examining its physical characteristics , such as color, appearance, and density . Furthermore, the compositional 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. Ultimately , sensory attributes , including flavor and odor, are also assessed to determine its suitability for various applications . These combined factors provide a holistic view of the oil's overall worth .
Refined Sunflower Oil – Detailed Analytical Findings
Recent testing of a sample of read more 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%, showing excellent refining efficiency. Furthermore , 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 (around 65%), oleic acid (approximately 27%) and palmitic acid (roughly 10%). Very small 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 scientific evaluation reinforces the high purity and quality of this refined sunflower oil.
