摘要
A process for removing free fatty acids from fats or oils of biological origin by extracting the free fatty acids with a mixture of basic organic nitrogen compounds and water as extraction medium at a temperature below the boiling point of the organic nitrogen compounds, such as herein described where the content of the basic organic nitrogen compounds in the extraction medium is at least about 20% by weight and at most about 60% by weight, preferably between about 30% by weight and about 40% by weight, and the boiling point of the basic organic nitrogen compound compound (s) used is equal to or above the boiling point of water and below the boiling point of the fatty acids to be extracted.
