Determination of the milk fat content of mixed spreadable fats
Abstract
This project is aimed at developing, validating, ring-testing, and documenting a reference method for the determination of the milk fat content in spreadable fats for official use in the Member States. The target will be achieved by a stepwise approach. Firstly, the fatty acid and triglyceride composition of authentic milk fats obtained from the Member States will be characterised by gas chromatography, liquid chromatography, Fourier-transform near infra-red spectroscopy, and nuclear magnetic resonance spectroscopy. Compositional data will be compiled and this data base will be made available to the Community in an electronic format (CD-ROM). In the next step, data of non-milk fats suitable for manufacturing mixed spreads and fat blends with an exactly known composition of fatty ingredients will be added to the data base. The information content of fatty acid and triglyceride profiles and of spectroscopic signals of the sample collection will then be used to set up calibration procedures by dedicated multivariate statistical procedures. The most promising analytical approach, i.e. the one with the least deviation of test results from known values, will be ring tested according to AOAC principles, and the standardised method will be delivered and published in CEN-style format. A work shop will be held for the Competent Authorities of Member States and other interested parties for a detailed demonstration of the principles of the developed testing method.
