Blog Article

A detailed assessment of sunflower oil's standard necessitates a multitude of demanding tests. These encompass examining its physical characteristics , such as color, clarity , and weight . Furthermore, the compositional profile is critically investigated , looking at parameters like free fatty acids, peroxide value – a key indicator of oxidation – and iodine value, which reflects unsaturation levels. Ultimately , sensory aspects, 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 value .

Refined Sunflower Oil – Detailed Lab Findings

Recent analysis of a batch 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%, illustrating excellent refining efficiency. Moreover , 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 (approximately 27%) and palmitic acid ( about 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 scientific evaluation reinforces the high purity and quality of this refined sunflower oil.
