Ethanol stability


, : Ethanol stability. Advanced dairy chemistry 1: Proteins (Ed. 2): 657-689

This subject is reviewed under the following headings: alcohol-stability test (historical introduction, ethanol stability/pH profile, factors affecting profile parameter values, lactational and compositional effects, factors relevant to the mechanism of alcohol destabilization, effects of processing milk, and ethanol stability and heat stability); ethanol stability and casein micelle structure (casein micelle stability, ethanol addition and steric stabilization of casein micelles, micellar core radius and its consequences, and implications for structural models of the casein micelle); mechanism for alcohol destabilization of milk protein; and practical applications (cream liqueurs).

In vegetable oil-ethanol emulsions ethanol is the polar phase and vegetable oil is the nonpolar phase. The primary advantage of vegetable oil-ethanol emulsions over conventional water-oil emulsions is that they enable the incorporation of water- a...
