A complete analysis of sunflower oil's grade necessitates a multitude of rigorous tests. These encompass examining its physical features, such as color, transparency , and density . Furthermore, the chemical profile is critically examined , 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 even assessed to determine its suitability for various purposes. These combined factors provide a holistic understanding of the oil's overall worth .
Refined Sunflower Oil – Detailed Lab Findings
Recent examination of a lot of refined sunflower oil revealed notable details regarding its composition and quality. The findings 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 stability . Specific fatty acid profile analysis identified a dominance of linoleic acid ( approximately 65%), oleic acid ( near 27%) and palmitic acid ( about 10%). Very small 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.
