Remarks This proficiency testing is an excellent tool for your extern assurance for sensory analysis of milk products and of food flavourings.. In addition it serves as recognizied proof of the compentence of your testing panel in the external appearance. The sensory triangle test is one of the most important sensory difference tests and an established quality assurance measure. The comparability of the organoleptic testing is the necessary prerequisite. With our proficiency testing schemes you can ensure the comparability of your organoleptic testing and demonstrate this in external representation. The proficiency testing serves to ensure the compliance with legal regulation of minimum requirement of fat in butter. The fatty acid pattern gives an information about the composition of the fat and is an information about the used fat in regard to polyunsaturated fatty acids and saturated fatty acids. The anaylsis of the value assessing parameters in yoghurt is requested in this proficiency testing round. Whey is a product which derives from the cheese production. Especially the whey protein is of high nutritional value. To show the comparability of the chemical-physical testing of whey this proficiency testing is suitable. Additives for stabilisation in dessert can lead to incorrect interpretation in the analyse of fat, dry matter and protein, e.g. in the IR-spectroscopy. This proficiency testing is suitable to demonstrate your competence. AMF is a product which is primarily used in industry. Negligence in the production can create features which are undesired, e.g. a high peroxide value.
