Sunflower Oil: Comprehensive Quality Assessment
A thorough analysis of sunflower oil's grade necessitates a multitude of strict tests. These include examining its physical features, such as color, appearance, and weight . Furthermore, the fatty acid 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. Finally , sensory qualities , including flavor and odor, are too 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 Analytical Findings
Recent testing of a sample 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%, showing 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 (around 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 comprehensive evaluation reinforces the high purity and quality of this refined sunflower oil.
