Statistical Interpolation of Spatial Data: Some Theory for Kriging

This disclosure covers a method of removing a preselected portion of the fat or oil from the surface of a vessel of aqueous fluid. An edible carbohydrate fatty acid ester in powdered form (preferably cellulose laurate) is added to the fat and absorbs several times its own weight in fat. The fat laden cellulose laurate is removed from the fluid in the vessel, and, if the fat is extracted from the cellulose laurate; it can be reused.
