Global food scandals are becoming more frequent. To make food safer, the researchers say they have to know the origin of the food in advance. A laboratory in Hamburg had the machine for this.
One undeniable fact of life is that most people do not know the ingredients in the food on the plate . Eating is produced on an industrial scale .
So is the growing number of food commodities traded in the international market . This means that when a food scandal emerged , can affect consumers around the world , at the same time .
For
many German consumers , food scandals continue to emerge in the last
few months and years have undermined confidence , especially against a
supermarket .
February 2013 , more than 12 European countries horse meat scandal exposed . Up to 5 percent written as a product in a supermarket beef turned out to contain horse meat in large quantities . It is not seen as a major health threat , but the scandal was sparked concerns about the lack of transparency in food labeling .
Then
in early November , a number of the cheese products pulled from stores
in the north of Germany because of listeria contamination .
The destruction of trust
At
the University of Hamburg , Professor Mark Fischer on a mission to
restore consumer confidence , at least up to a certain point .
One of the machines used in the laboratory is GCMS Fischer .
" MS stands for mass spectrometry , " Fischer explained . " We use it to measure metabolites . This is a methodology that can be used to check the origin of food . "
His team developed a method for determining the geographical origin of food products .
In
an increasingly globalized world , said Fischer , the geographical
origin of the raw materials is becoming increasingly important .
Origin
of a product is often used for a unique marketing concept - chocolate ,
for example , called contains cocoa beans from a specific region .
" It's not a health issue , " said Fischer . " It does not matter if the chocolate beans come from Ecuador or Ghana . "
However, there are cases that the origin of the food has health implications .
" Take the example of fish , " said Fischer . " In this case it is certainly important if the fish comes from the Fukushima region , or from the North Sea . "
Fingerprints groceries
Using mass spectrometry to analyze metabolites a food sauce to be one way to determine the geographical origin .
Analysis gave researchers what they call the metabolic fingerprints . This fingerprint can then be compared with the reference sample . Fingerprints similar means foods tested were from the same region . Tim Fischer can also analyze samples based on DNA and protein content of the food .
School
of Food Science at Hamburg had just started a scientific collaboration
with the Food and Drug Administration USA ( FDA ) . The FDA is one of the largest organizations in the world's food monitoring .
For the first time , the FDA in cooperation with a German university . It reflects the growing global food supply chain .
Professor Fischer for this cooperation be an efficient way to share the knowledge in areas of expertise vary .
