  • ADDITIVES AND USE THEREOF IN CORN FERMENTATION PROCESS STREAMS AND OTHER BIOPROCESSES
    Publication number: 20230263204
    Abstract: 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.
    Type: Application
    Filed: May 1, 2023
    Publication date: August 24, 2023
    Inventors: Kenneth L. ZACK, Joseph P. BORST, Yaser SHIRAZI, Padma P. VARANASI, Matthew Gerard LYON
