Method for Determining Volatile Acids in Cultured Dairy Products

Abstract
A simplified and accurate method for determining the volatile acids from cultured dairy products by steam distillation is described. Results obtained were comparable to those reported by Dyer (1917). This method gave rapid and accurate determinations of the volatile acids present in cultured dairy products. Steam distillation worked as well as centrifugation for preparing sour cream samples for gas chromatographic analysis of volatile acids. Volatile acidity content as well as acetic acid content could, therefore, be determined with a minimum of time and effort.
