Latest Patents

Xu’s patent, “Method of Efficiently Separating Solid Fat from Polyunsaturated Fatty Acid Grease,” describes adding inert material to PFAG, cooling the mixture to crystallize fats, and filtering it to separate clarified grease from the solid-containing filter cake. The cake is then heated and dissolved before further filtration to recover solid fat.

The method is designed to separate saturated and low-saturation fatty acids efficiently. It shortens winterization crystallization time, supports complete crystallization, and makes crystals easier to separate. By reducing the time required for separation and drying, the process helps prevent solid fat from melting back into the filtrate. The patent reports a final product yield of 96.3% to 98.2%. It also describes good lipid clarity after winterization, with no crystal precipitation at 0°C for five hours.

Career Highlights

Xu’s documented patent contribution focuses on improving the separation and recovery of solid fat from PFAG. The disclosed process combines controlled crystallization, inert material, and filtration to improve separation efficiency and product yield.
