Method and kit for testing for the presence of catalase in milk

Abstract

A METHOD AND KIT FOR TESTING FOR THE PRESENCE OF CATALASE IN MILK ABSTRACT OF THE DISCLOSURE The invention provides a method for testing for the presence of catalase in a milk sample comprising combining a milk sample with a substantially catalase-free alkaline protease enzyme enriched detergent to disrupt catalase containing somatic cells present therein and release active catalase therefrom in the present of a pH buffering salt having a concentration of at least 20mM in the resulting sample solution and providing the solution with a pH in a range of about 7.0-8.0 and thereafter testing the sample for the presence of catalase, as well as providing a test kit for detecting the presence of catalase in milk comprising a substantially catalase-free alkaline protease enzyme enriched detergent and 20 to 400 micromoles of a pH buffer alone or in combination with any other solute capable of reducing the solubility of oxygen in milk and of providing the resulting milk solution with a pH in the range of about 7.0-8Ø
