The present invention relates to methods for the separation and fractionation of lipid materials, in particular fatty acids and fatty acid esters, according to their degree of unsaturation. more specifically, the invention concerns solvent-free processes in which lipid blends are frozen into rigid bodies and subjected to centrifugal forces to expel unfrozen fractions
The solvent-free process forms a rigid lipid matrix by cooling and applying centrifugal forces to separate lipids, addressing inefficiencies in conventional methods and enabling high-purity lipid fractionation.

AI Technical Summary
Technical Problem
Conventional lipid separation technologies rely on solvent-based fractionation, which is costly, environmentally harmful, and inefficient, while solvent-free methods are limited in purity and efficiency, and centrifuges are not optimized for frozen lipid masses.
Method used
A solvent-free process that forms a rigid solid lipid matrix by cooling lipid blends below crystallization temperature, then applies centrifugal forces to expel unfrozen fractions, using prefabricated or in-situ frozen forms.
Benefits of technology
Achieves high-purity separation of saturated and unsaturated lipids efficiently, reducing energy and solvent use, suitable for food, nutraceuticals, and biofuels production.

Abstract
The invention is related to a process for separating lipids of differing degrees of unsaturation, comprising forming crystals in a lipid blend and separating liquid and solid fractions by a separation step The lipid blend is first cooled to a temperature below the crystallisation temperature of at least one higher-melting component to obtain a rigid solid lipid matrix, and the rigid solid lipid matrix is then subjected to centrifugal forces of at least 500g (RCF) to expel a liquid fraction enriched in lower-melting, more unsaturated lipids, the separation being carried out in the substantial absence of added solvent.
