Abstract: The present invention relates to an oil comprising at least one polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA). It is found that LC-PUFA-containing oil are susceptible to gelling by formation of microscopic crystals during storage ultimately resulting in unfavorable quality and handling properties.
