DEVELOPMENT OF ADVANCED ANALYTICAL METHODS TO DETERMINE THE AUTHENTICITY OF FRUIT JUICE

Objective

The authenticity and purity of fruit juice products is extensively monitored for purposes of consumer protection, good trading practice and Community customs classification. Where they exist, the National systems of assessment for quality identity and authenticity (e.g. AFNOR, RSK, respectively in France and Germany) are generally based on previous practice of production and trade and the analytical methods are based on conventional procedures of analysis (IFU methods and recently issued CEN methods). This situation will not meet future needs because of the ingenuity of those who falsify and manipulate has become more and more sophisticated.

A number of methods used to detect the most common adulteration will be studied. They include the determination of characteristic substances:

- anthocyanins and carotenoids
- flavonoids
- organic acids
and the determination of exogenous sugar by NMR, MS and detection of oligosaccharides by combined HPLC gas chromatography.
