Liquid milk — Determination of acid-soluble beta-lactoglobulin content — Reverse-phase HPLC method

ISO 13875|IDF 178:2005 specifies a method for the quantitative determination of the beta-lactoglobulin content, soluble at pH 4,6, in liquid milk. The method has been tested over a range between 0 mg and 3 500 mg of beta-lactoglobulin per litre of milk. It is suitable for distinguishing different categories of heat-treated liquid milk.
