Rapid Protein Residue Tests

Are you looking for a fast way to verify your cleaning procedure?

With AllerSnap™ and PRO-Clean™ general protein swabs, you can easily verify the cleanliness of your production environment. General protein swabs work by detecting protein residues left behind on countertops, conveyer belts, and any other working surfaces. While allergen-specific tests remain the gold standard of gluten and allergen management, pairing them with general protein swabs increases the amount of data you can collect. Plus, more data means a decreased risk of undetected allergen cross-contact.

Protein tests will react to all sorts of proteins, and do not differentiate between proteins from FALCPA allergens like peanut, soy, or milk and proteins from other sources like chicken or chickpeas. The results are semiquantitative: green means clean, but the darker purple the liquid turns, the more protein was found on the surface.

Checking for residual protein on surfaces is a helpful component of any allergen control plan, but it is not a replacement for allergen-specific testing with kits like AlerTox Sticks or GlutenTox Pro, or for third party lab analysis. 

Are protein swabs a good match for your business?

Protein swabs are portable, rapid and cost effective supplement to your comprehensive allergen management plan. Any safety team that is concerned with controlling for food allergens, whether you are a food processor, a hospitality kitchen or a supermarket kitchen, will find these easy-to-interpret surface swabs an essential tool.

How do protein residue tests work?

AllerSnap™ and PRO-Clean™ uses the biuret method, which is a broad spectrum monitoring method primarily used to verify your cleaning SOP. The test is easy: swab the testing area and snap the bulb to release a reagent. PRO-Clean does not require any further steps. To use AllerSnap™, incubate the swabs for 5-30 minutes then match the color to the chart: green means clean and purple means re-clean. The incubator is a necessary piece of equipment; the tests cannot be conducted without incubation.

The swabbing procedure is the same for PRO-Clean™, however no incubation is necessary. The swabs are less sensitive than AllerSnap, however.

The biuret method is a colorimetric technique specific for proteins and peptides. Copper salts in alkaline solution form a purple complex with substances containing two or more peptide bonds. The absorbance produced is proportional to the number of peptide bonds that are reacting and therefore to the number of protein molecules present in the reaction system ~Read the article on Science Direct

Looking for a more sensitive allergen control solution?

AlerTox Sticks® kits are sensitive, on-site LFD tests that have the flexibility to test products, ingredients and rinsewater as well as surfaces. AlerTox Sticks come in a variety of allergens: almond, crustacean, egg, fish, hazelnut, milk, mustard, peanut, soy, and walnut.

Note! SOME swabs require the use of an Incubator.

AllerSnap requires a simple incubation step with a dry-block incubator, which is sold separately.
