They wereacetylated by different concentrations and their effectiveness properties werestudied. It was found that the sour whey(unsalted and acetylated) exceeded itscounterpart of treatments in the percentage of moisture and ash. However, thesalted and unsalted sweet whey(acetylated) had significant superiority overother treatments, in the following properties; total protein, foam size, gelformation, oil and water absorption, and the emulsification properties. Thus, theresults showed that the 0.5٪ of acetylation for salted and unsalted sweet andsour whey proteins was the best in changing the functional properties of theacetylated whey protein concentrates compared to the acetylation percentage0.3٪ and 0.9٪, respectively. In addition, the salt effect in most treatments hasshown a significant effect. So, the above results showed that salted sour andsweet whey protein are the best in the process of acetylation because of itsimprovement of functional and chemical properties.Key words: whey protein concentrates, acetylation, functional properties, Anhydrous AceticAcid .
