Residues remaining on surfaces indicate poor cleaning and could contain
potentially allergenic proteins, which could lead to product contamination.
3M Clean-Trace Surface Protein (Allergen) is a simple method of checking for
removal of protein residues after cleaning. As the majority of allergens are
proteins, if a surface is found to be protein-free, it is also free of
Simple and very sensitive swab test for the detection of protein residues on surfaces and in solution.
60 test swabs per case. Requires a Heating Block or similar, set to 131°F (55°C) for 15 minutes.
Checking for removal of protein residues after cleaning can quickly identify
contamination. As the majority of allergens are proteins, if a surface is found
to be virtually protein-free, it indicates low risk of allergens being present.
Validated for a range of allergenic proteins, including egg, milk, gluten, soy
