Walnut Free Test

Walnut Free Test is a Lateral Flow test that determines walnut residues in food products, cip solutions and working surfaces.

GENERAL INFORMATION:Walnut (Juglans regia) belongs to the walnut plants (Juglandaceae). Walnut contains a high amount of proteins (approximately 16%). Many walnut proteins, such as rJug r 1 and rJug r 4 are allergenic. Most of them are very heat resistant making them stable to different production processes. Consumption of walnut might be harmful for people who are allergic to it. The allergen can be present as an ingredient or as a contamination in raw and cooked products. Consumption of walnut-containing food from allergic people might cause a broad range of symptoms, such as hives, mild oral allergy or/and anaphylactic shock. According to the regulation (EU) No. 1169/2011 Annex II, walnut is included in the list of allergens established by the European Food Safety Authority, and its presence must be indicated on the label. Similar regulations exist e.g. in the USA, Canada, Australia and New Zealand.
