NIR-spektroskopisk analys av kexchokladfyllning
2001 (Swedish)Independent thesis Basic level (professional degree)Student thesis
Abstract [sv]

Syftet med detta examensarbete var att ersätta befintlig analysmetod för fett i chocklad med den snabbare NIR (Near InfraRed) analysen. Detta gjordes genom att ett stort antal prover samlades in och analyserades med NIR samt med referensmetoden NMR (Nuclear Magnetic Resonance). Den insamlade datan behandlades därefter i dataprogrammet SESAME och en kalibreringsmodell beräknades mha MLR (Multipel Linear Regression). Resultatet blev en fullt godtagbar kalibreringsmodell som Cloetta nu använder sig av.

Abstract [en]

The purpose with this project was to replace the method, (NMR-Nuclear Magnetic Resonance), for analysing fat in choclate with NIR (Near InfraRed). This was done by gathering a lot of choclate samples which was then analysed by NIR and by a reference method (NMR). The data that had been gathered was then treated with the dataprogram SESAME which established the best calibration model by means of MLR (Multipel Linear Regression). The result was an fully acceptable calibration model which is now used by Cloetta.
