Estimating the term…
The present disclosure provides compositions and methods for enhancing oil recovery and protein recovery from a product from a corn fermentation process stream, such as corn syrup. Compositions generally include a product from a corn fermentation stream and an additive including at least one alkylphenol ethoxylate formaldehyde resin, at least one sodium alkyl sulfate, or a blend of at least one anionic surfactant with at least one non-ionic surfactant in a weight ratio of the at least one nonionic surfactant to the at least one anionic surfactant in a range from about 1:20 to about 20:1. Methods combine such an additive with the product from a corn fermentation stream to produce a mixture which is preferably heated and centrifuged to separate oil and protein from the product.
A composition comprising a product from a corn fermentation process stream, wherein the product is selected from the group of beer, whole stillage, thin stillage, and corn syrup, and at least one additive comprising alkylphenol ethoxylate formaldehyde resins or sodium alkyl sulfate.
A composition comprising a product from a corn fermentation process stream and an additive, wherein the additive comprises a blend of at least one anionic surfactant and at least one nonionic surfactant, wherein the at least one nonionic surfactant comprises an alkylphenol ethoxylate formaldehyde resin, and wherein the weight ratio of the at least one nonionic surfactant to the at least one anionic surfactant is in a range from about 1:20 to about 20:1.
