Abstract: A process is described for separating deodorizer distillates, which are byproducts from processing vegetable and animal fats and oils, into a light fraction enriched in fatty acids and a heavy fraction enriched in tocopherols and sterols. Melted deodorizer distillate is added to a heated solution of urea dissolved in alcohol. The solution is preferably non-aqueous but may contain small quantities of water as an impurity. A crystalline complex of urea and fatty acid is formed which is removed from the solution and dried. The remaining mother liquor is saved for subsequent processing. The dried crystals are dissolved in water to yield an organic layer of fatty acids and an aqueous layer of urea. An organic fraction rich in tocopherols and sterols is separated in the same manner from the mother liquor, which was saved previously, by evaporating the alcohol to form a residue, mixing the residue with water and separating the organic layer.
Abstract: A high speed corrugating adhesive having a carrier phase comprised of starch, modified starch or dextrin and polyvinyl alcohol in an aqueous emulsion wherein a cold water soluble, partially hydrolyzed, polyvinyl alcohol is used as a starting material. The polyvinyl alcohol is further hydrolyzed in situ to a degree of hydrolysis of more than about 95% by heating it in the presence of water, caustic, and starch, modified starch or dextrin. The carrier phase is admixed with a boron containing compound and a suspension of water and starch to prepare the corrugating adhesive for use in a corrugating machine.

Abstract: A process for producing corn fiber having a high total dietary fiber content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-millng process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction may then be passed into a centrifual paddle screen to give a product of even higher total dietary fiber content.
