Brazil Nut

Note: We only carry the Brazil nut Lateral Flow Test.

Brazil nuts, in combination with other tree nuts, constitute a relatively common cause of food allergy, capable of triggering fatal allergic reactions in sensitive individuals. Accordingly, food labeling laws in many countries require food labels to clearly indicate Brazil nut content. To assist the food industry in establishing effective food safety practices, AllergenControl™ has developed a rapid test kit that can reliably detect Brazil nut residues in food, on surfaces and equipment.

Intended Use

This test kit is designed for use in the qualitative determination of Brazil nut residues obtained from sampling foods (solids, powders, and liquids) and surfaces. The test is intended for laboratory use only and should only be performed by trained personnel.

Assay Principles

The AllergenControl™ Brazil Nut Residue Lateral Flow Test features polyclonal antibodies directed against Brazil nut proteins configured in a sandwich format. To operate the kit, the sample is first subjected to a short extraction step. The sample extract is then directly applied to the lateral flow device sample port, where it is allowed to migrate across the reagent zone thus enabling visualization of the Sandwich Test Line (T) results. In addition, the reagent zone includes a Procedural Control Line (C) to minimize the potential for false negative outcomes.
