The article is devoted to methods of concentrating and purifying omega-3 polyunsaturated fatty acids (PUFAs). The text discusses methods such as transesterification, urea complexation, chromatographic methods, low-temperature crystallization, supercritical fluid extraction, molecular distillation, and iodolactonization.
The aim of the research is to systematize literature data to identify the most effective methods for obtaining pu-rified, concentrated omega-3 PUFAs. The methods include transesterification for converting triglycerides into ethyl esters, urea complexation for separating fatty acids, chromatographic methods for high product purity, low-temperature crystallization for simplicity and cost-effectiveness, supercritical fluid extraction for environmental cleanliness and efficiency, molecular distillation for high selectivity, and iodolactonization for prospective separa-tion of omega-3 acids.
The article discusses the advantages and disadvantages of methods for concentrating omega-3 PUFAs. It also considers the prospects for developing effective and economical methods of enriching omega-3 fatty acids to re-duce costs and meet future demand for highly purified products.
