Studies on detectability of GMOs in milk during milking and dairy processing.
Abstract
Detecting the use of genetically modified feeds has become important, because the voluntary labelling of milk and dairy products as 'GMO-free' or as 'Organically Grown' strictly prohibits the employment of genetically modified feeds. Controlling GMOs in milk originating from feeds requires DNA-markers, which are intact and fit for PCR amplification after digestion and transportation via the blood circulation. These markers from feeds or from ingredients added to dairy products would need to remain stable during processing and storage until examination. In regard to milk and dairy products the marker-DNA sequence to be provided for analysis would have to stay unaffected through heating and/or fermentation processes. The first part of this project deals with analytical methods to purify marker-DNA from the rather complex food system 'milk'. During the second part the recovery of this marker-DNA from blood and milk after ingestion is examined. Finally, during the third part the stability of marker-DNA added to milk prior to technological treatment is determined.
