If there is an oil or fat with triglycerides with a range of melting points present, it is possible to separate them by fractional crystallisation. This can then enable products with more specific solid/liquid characteristics to be produced with better functionality in the product and therefore of a higher value. The process “trick” is to crystallise and separate these various triglycerides. The quality of separation of crystals from any remaining liquid oil is called the separation efficiency (SE), where 100% SE means perfect removal of all liquid oil from the crystals.
