Effect of supercritical fluid extraction on the reduction of toxic elements in fish oil compared with other extraction methods

High-quality fish oil for human consumption requires low levels of toxic elements. The aim of this study was to compare different oil extraction methods to identify the most efficient method for extracting fish oil of high quality with the least contamination. The methods used in this study were Sox...
