Free fatty acids (FFAs) are extracted from oils through a process involving basic organic nitrogen compounds and water. The process involves using a mixture of basic organic nitrogen compounds and water as an extraction medium at a temperature below the boiling point of the organic nitrogen compounds.
Here's a breakdown of the process:
- Extraction Medium: A mixture of basic organic nitrogen compounds and water is used.
- Temperature: The extraction occurs below the boiling point of the organic nitrogen compounds.
- Purpose: To remove free fatty acids from fats or oils of biological origin.
In essence, the process selectively pulls the FFAs out of the oil using a specific solvent system and controlled temperature. This process is based on acid-base chemistry where FFAs (acids) react with the basic organic nitrogen compounds, thereby separating them from the oil.
