dc.description.abstractSterile (milk) powders were tested for their properties for use in preparing microbiological reference materials. Physical properties and the survival of bacteria in mixtures of highly contaminated milk powder with sterile (milk) powder were examined. Preparing more predictable homogeneous powders was possible by carrying out a pharmaceutical way of premixing in a mortar and final mixing in a mixing apparatus. The direct use of contaminated mixed milk powders without the protection of the gelatin capsules does not seem to be a more user friendly alternative for the capsules.<br>

html.description.abstractSteriele (melk)poeders werden op hun eigenschappen getest voor mogelijk gebruik bij het bereiden van microbiologische referentiematerialen. Zowel fysische eigenschappen als de overleving van de bacterien in de mengsels van hoogbesmet melkpoeder met steriel (melk)poeder werden getest. Het bereiden van meer voorspelbare homogene poeders was mogelijk door een farmaceutische manier van voormengen in een mortier en namengen in een mengapparaat. Het direct gebruiken van gemengde besmette melkpoeders, zonder de bescherming van gelatine capsules lijkt geen gebruikersvriendelijker alternatief te zijn voor de capsules.&lt;br&gt;
