For the majority of the general public, the consumption of food is harmless. However, it may cause life threatening reactions in food allergic subjects and dramatically restrict the quality of life.
Scientists estimate that approximately 2 – 4 % of adults and 6 – 8 % of children suffer from food allergies as well as the huge number of persons with food intolerances, their prevalence is difficult to estimate, due to missing studies. Different to food intolerances, real food allergies are highly dangerous for patients, because they are caused by errant immune reactions. These reactions are usually triggered by proteins; allergic subjects are already sensitized to these proteins.
The labelling of these allergenic proteins, called allergens, is of great importance for allergic subjects. In this context, hidden allergens are dangerous due to their appearance, for example in convenience food or as unintended contaminations of food during storage and production.
To protect allergic persons from undesired consumption of allergens, the food labeling regulation of the EU was passed. This EU regulation is continuously updated and revised (EU regulation 1169/2011, became effective in December 2014). Since November 2005, food producers are committed to label ingredients which can cause allergies or intolerances. This includes following substances and food produced from them:
- Gluten containing cereals
- Tree nuts
- Sesame seeds
Furthermore, sulfur dioxide and sulfites in a concentration more than 10 milligram per kilogram must be labelled. Other countries also have labelling regulations, adapted to country-specific allergens, e.g. concerning:
In most production lines, more than one product is produced which may result in unintended contaminations with allergens. To protect consumers and to assure an adequate labelling, a reliable allergen analysis must be applied. For this purpose, R-Biopharm provides immunochemical as well as molecular biological techniques.
