Foodstuff Production:utilising knife mills to ensure greater analysis accuracy

摘要

Time and time again consumers are confronted with scandals in the foodstuff industry.The latest case is the Fipronil egg scandal in the hen egg farm in the Netherlands [1] and in Lower Saxony(Germany)[2],What actually do foodstuff producers and marketers do to avoid such cases? A lot,if you believe the rising costs in the area of modern foodstuff analysis.Over the past decades,newer and more sophisticated processes have and will continue to be developed with the most sensitive detection thresholds(ELISA,PCR or the mycotoxin analysis)for quality control.The purpose of this is to lower the number or even eliminate such scandals and the potential danger for consumers.In the context of these analytical processes,again and again,methods for sample preparation of the most diverse matrixes have been developed.In the case of foodstuffs and the raw materials,convenience products are often composed to be clearly more heterogeneous than all other substance groups.Especially in regards to comminution,there are often limits,such as the rheological properties of a material,the ingredients or the volatile components,which can only be prepared without regulating factors(sieves).This is why knife mills are often utilised.Fritsch now offers such a knife mill in industry quality:the Knife Mill PULVERISETTE 11.Some examples of the comminution of foodstuffs and their backgrounds are explained below.
