    Detection of Gluten in industrial bakery

    Sources: Study carried out by a french industrial bakery


    The number of gluten-free consumers has increased greatly in recent years and more and more food industries are trying to develop a range of gluten-free products in order to fulfil the need.
    This study is aimed at evaluating the level of gluten contamination in a 2000m3 production workshop in an industrial bakery. The objective was to create a specific area in the production workshop dedicated to the production of gluten free products.
    The Coriolis® Micro has been used to perform air sampling at various points in the bakery during production and also when the machines were stopped. The samples have been then analyzed by ELISA.


  • Results of the air sampling performed in the first area
  • gluten detection
    The level of gluten detected with Coriolis® Micro in this area is at the detection limit of the analysis method. An increase of the gluten concentration is observed when the sampling is performed during the production. This moderate increase has to be confirmed by further trials.

  • Results of the air sampling performed in the second area
  • gluten detection 2
    During the production, the level of gluten detected in the area is high. The installation of a gluten-free production line close to this area is not possible because of the high risk of cross contamination.
