A complete analysis of sunflower oil's quality necessitates a range of demanding tests. These encompass examining its physical features, such as color, clarity , and density . Furthermore, the fatty acid 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. Finally , sensory attributes , including flavor and odor, are even assessed to determine its suitability for various purposes. These combined factors provide a holistic picture of the oil's overall value .
Refined Sunflower Oil – Detailed Lab Findings
Recent examination 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 longevity. Specific fatty acid profile analysis identified a dominance of linoleic acid ( roughly 65%), oleic acid (approximately 27%) and palmitic acid (roughly 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.
Laboratory Analysis of Sunflower Oil: A Technical Review
The evaluation of sunflower petroleum quality necessitates comprehensive laboratory examination, encompassing a range of mechanical and organoleptic properties.
- Free fatty acid content assessment, typically utilizing volumetric analysis , is crucial for gauging degradation .
- Peroxidation measures initial oxidation levels, employing a spectrophotometric technique.
- Pigment analysis, often conducted with a colorimeter against established scales , is vital for consumer appeal and assessing processing impacts.
Sunflower Oil Quality Report: Key Parameters and Results
This analysis details the quality of the obtained sunflower oil, evaluating several critical parameters. Significant measurements included FFA , which registered at 0.28% demonstrating a good level. Peroxide value, indicating oxidation, was found to be 5.0 meq/kg , within the regulatory guidelines. Hue was assessed using the Lovibond scale , resulting in a score of 30 . Furthermore, iodine value, representing unsaturation levels, came in at 125 , aligning with expected values for sunflower oil. The final result indicates the oil is fit for its intended use.
