One important function of alcohol is to facilitate the mixing of oil-based
ingredients into water-based products or water-based ingredients into oil-based
products. This is an important use in the production of flavors. Most flavors are oils. For example, orange flavor is oil derived from orange skins. Orange flavor does not dissolve in water but dissolves in alcohol. The mixture of alcohol and orange flavor then dissolves in water. So to produce an orange-flavored carbonated drink, alcohol is used to make sure the orange flavor is fully mixed and dissolved in the carbonated water and remains dissolved over the expected shelf life of the product (Othman and Riaz, 2000).
