Study of the physicochemical parameters of cottonseed oils produced in the CMDT zone in Mali

Abstract

The issue of edible oils consumed in Mali is a matter of concern to the authorities. After the closure of the cotton oil mill in Mali (HUICOMA), a hundred economic operators had established themselves in this niche. Today the market is flooded with poor quality cottonseed oil. This study was conducted in order to assess the quality of the refined oil produced by twelve cottonseed oil production units. The objective was to analyze the physicochemical parameters of refined cottonseed oil produced by small production units. After sampling and analysis of the parameters according to Codex Alimentarius standards, the following results were obtained: refractive index 100% non-compliant; density: 100% compliant; the peroxide index: 36.67% compliant; Acid number: 85% compliant; soap content: 100% compliant; iodine number 37.10 to 48.50 g of I2/100g; saponification index 85% non-compliant; unsaponifiable matter 100% compliant; traces of gossypol, 75% non-compliant. These results showed that certain oils were detrimental to the health of consumers. Investigations, particularly at the level of technological chains for the extraction and packaging of oils in these units would be necessary. © 2022 International Formulae Group. All rights reserved.
