Patent number: 12076664Abstract: Alkyl ether amines are used as foam control compounds in foodstuff processing. The alkyl ether amines can be used at various stages during industrial processing of vegetables, fruits, and plants, such as potatoes and beets. The alkyl ether amines are generally of lower molecular weights and therefore easily transported to the foam layer to break the foam structure. Further, the alkyl ether amines are water soluble and therefore can be readily removed from the food processing system.Type: GrantFiled: September 17, 2019Date of Patent: September 3, 2024Assignee: Dow Global Technologies LLCInventors: Xue Chen, Stephen W. King, Felipe A. Donate
