How does it work?
|Primary objective||reduce mycotoxin contamination in wheat lots|
|Working principle|| This method showed that:
- during the milling processes, the deoxynivalenol (DON) is concentrated in both the fractions corresponding to the most peripheral tissues and the finest particles generated from the operating units
- the content of both the fungus (Fusarium type) and its product, the mycotoxin (DON), appears to decrease around the aleurone layer (probably next to the testa-aleurone border). Consequently, it is highly suggested to choose debranning/dehulling over milling to reduce DON level in the products.
Due to an effective reduction of grain mass by grain processing using debranning methods, the mycotoxin will be removed
|Important process parameters||It is highly suggested to choose debranning/dehulling over milling. Milling would increase the contact between the contaminated tissues and the flour, resulting in a contaminated product.|
|Important product parameters|
What can it be used for?
|Products||Durum wheat, common wheat|
|Operations||Grinding, milling, debranning/dehulling|
|Solutions for short comings||Reduction of mycotoxins/contaminants|
What can it NOT be used for?
|Products||any other product than wheat|
|Operations||Other operations than separation (by grinding, milling, debranning/dehulling)|
|Other limitations||The method does not allow to reach a 100% elimination rate|
|Risks or hazards|
|Maturity|| This method has not been implemented on industrial scale yet.
It should be coupled with other mycotoxin reduction methods (such as grain size sorting, colour sorting, etc.)
|Modularity /Implementation||This technology should be applied prior to the conventional production line (i.e. before milling)|
|Consumer aspects||Consumers will definitely benefit from higher reduction of the amount of potentially toxic molecules|
|Legal aspects|| The European law N°1881, 2006 describes the deoxynivalenol (DON) acceptable tresholds within several conditions:
Durum wheat 1750 µg.kg-1
Semolina, pasta 750 µg.kg-1
Common wheat 1250 µg.kg-1
Flour, bread 500 µg.kg-1
Infant food 200 µg.kg-1
|Environmental aspects||Debranning/dehulling is an energy consuming process|
