RIDASCREEN®FAST Mustard is a sandwich enzyme immunoassay for the quantitative analysis of mustard in ketchup, sausage and cream cheese.
People allergic to mustard will react to any ingredient of black, Indian brown or yellow / white mustard. Even small traces of allergens in food can trigger allergic reactions in sensitive individuals. Mustard is used as a condiment in meat, to prepare pastes or as an ingredient for a large variety of sauces, soups, salad dressings, and marinades. Thus, it is frequently encountered in food as a hidden allergen. Food manufacturers have to check for crosscontamination. The allergen can be present as an ingredient or as a contamination in raw and cooked products. According to the regulation (EU) No. 1169/2011, mustard and products thereof must be declared on food labels.
