Abstract

The aim of this project is to develop the use of NMR spectroscopy as a rapid and routine method for the measurement of the composition of certain food mixtures. This aim is to be achieved by the direct application of chemometrics (or pattern recognition) techniques to the spectral data. Objective assessments of food quality and authenticity depend on the measurement of a wide range of components present in each type of food. The sensory qualities of the food or suitability of a raw material for further use often depend in a complex way on the balance of the different components. Many of the available analytical methods are specific for a particular type of compound and require involved extraction or derivatisation procedures. High resolution NMR spectroscopy is a quantitative technique capable of detecting many types of chemical compound in a single experiment, and, for liquids or solutions, requiring little in the way of sample preparation. Multivariate statistical treatments of the NMR data will be developed for a) classification of samples according to origin, quality etc.; b) measurement of the concentrations of individual components. The calculations may be carried out on a personal computer, and the whole procedure has the potential to be highly automated.
