| Researchers have developed a method for free fatty acid (FFA) separation and recovery in the deacidification process of vegetable crude oils. When free fatty acids are present, in oil processing, they can produce alkali soaps which pollute the final product. Using a particular resin to recover FFAs, this method can reduce FFA saturation to under 1%. Additionally, the resin can be reused to adsorb FFAs through several cycles, and the FFAs can then be recovered and used to create value-added products. |
