Title (EN) COMPOSITIONS AND METHODS FOR DETECTING ALLERGENS
(FR) COMPOSITIONS ET PROCÉDÉS POUR LA DÉTECTION D’ALLERGÈNES
Abstract:
(EN) Compositions and methods for detecting food-based allergens on a surface are disclosed. A composition can include ninhydrin and a protease enzyme. The protease enzyme can be a cysteine protease enzyme, an aspartic protease enzyme, or combinations thereof. In some embodiments, the composition can include a carrier. Methods of detecting a food-based allergen on a surface can include providing a composition including ninhydrin and providing a protease enzyme. The method can include applying the composition and the protease enzyme to the surface. The method can also include allowing the ninhydrin and the protease enzyme to interact with particulates from the surface for a detection period. Detecting the food-based allergen can occur when the composition changes color after the detection period.
(FR) L'invention concerne des compositions et des procédés pour la détection d'allergènes alimentaires sur une surface. Une composition peut comprendre de la ninhydrine et une enzyme protéase. L'enzyme protéase peut être une enzyme cystéine protéase, une enzyme protéase aspartique ou des combinaisons correspondantes. Dans certains modes de réalisation, la composition peut comprendre un véhicule. Des procédés de détection d'un allergène alimentaire sur une surface peuvent comprendre l'utilisation d'une composition comprenant de la ninhydrine et l'utilisation d'une enzyme protéase. Le procédé peut comprendre l'application de la composition et de l'enzyme protéase sur la surface. Le procédé peut également consister à permettre l'interaction de la ninhydrine et de l'enzyme protéase avec des particules de la surface pendant une période de détection. La détection de l'allergène alimentaire peut se produire lorsque la composition change de couleur après la période de détection.
