Production and processing
A variety of chemical and physical techniques are used for the production and processing of fats, both industrially and in cottage or home settings. They include:
- Pressing to extract liquid fats from fruits, seeds, or algae, e.g. olive oil from olives
- Solvent extraction using solvents like hexane or supercritical carbon dioxide
- Rendering, the melting of fat in adipose tissue, e.g. to produce tallow, lard, fish oil, and whale oil
- Churning of milk to produce butter
- Hydrogenation to increase the degree of saturation of the fatty acids
- Interesterification, the rearrangement of fatty acids across different triglycerides
- Winterization to remove oil components with higher melting points
- Clarification of butter
