New Strategies for Tracing Foodstuffs: Biological Barcodes Utilising PCR-DGGE
Journal Title: Advances in Food Technology and Nutritional Sciences - Open Journal - Year 2015, Vol 0, Issue 1
Abstract
Traceability of foods is undertaken primarily at the administrative level, and the use of advanced analytical tools is rare. Nevertheless, the determination of geographical origin is a demand of the traceability system for the import and export of foodstuffs (UE regulation 178/2002). It is hypothesised that foodstuffs can be traced at source by analysing food sample microbial communities after they have been exported. For this purpose, rDNA profiles generated by PCR-DGGE may be used to detect variability in microbial community (bacteria, yeast, fungi) structures inherent to fish, fruits and grains. This is an emerging traceability tool that imprints food with a unique biological bar code and makes it possible to trace food to its original location. In addition, this analytical technique provides a means to monitor and fully understand the ecology of mycotoxin producing fungi.
