Deaeration refers to the removal of dissolved gases, such as oxygen and carbon dioxide from a substance. All beverages are sensitive to the presence of dissolved oxygen, which can substantially change their taste and color, and also adversely affect the filler performance. Manufacturers recognize the importance of using optimally deaerated water for the production of alcoholc and non-alcoholic beverages.
