A Flexible Experimental Set-up for Development of Spectrophotometric Analysers of Food

− A spectrophotometric analyser of food (SAF) is a spectrophotometric instrument dedicated to measuring physical and/or chemical parameters characterizing a predefined class of chemical or biochemical substances which appear in food raw materials or products. It is usually composed of a spectrophotometric transducer and a digital processor. The latter is transforming raw measurement data, provided by the transducer, into the final result of measurement, i.e. estimates of concentrations of selected compounds of the analysed sample. Thus, the R&D works related to SAFs require tools for development of algorithms of measurement data processing and tools for acquisition of measurement data to be processed by those algorithms. In this paper, a low-cost and flexible experimental set-up for the latter purpose is proposed, and practical examples of its application are given.
