Introducing: OnSite® Allergen Multiplex Tree Nut

This newly developed lateral flow test kit quickly detects traces of tree nut protein in rinsewater and on surfaces.

Allergen Multiplex Tree Nut at a glance:

  • Test works on surfaces and rinsewater
  • Simultaneously detects almond, cashew, hazelnut, pecan, pistachio, walnut
  • Detects as little as 1-5 mg/kg (ppm) of tree nut protein in rinsewater or  10μg/ 100 cm2 on surfaces
  • Requires no equipment
  • Results in less than 20 minutes
  • Sensitive to coconut protein at levels above 50 mg/kg (ppm)

Why are tree nuts so tricky to manage?

Tree nut allergies are among the most common food allergies for both children and adults. Accordingly, many countries consider tree nuts to be a major food allergen requiring careful labeling and hazard management. And because many individuals with tree nut allergies are not allergic to all tree nuts but only to some, allergen legislation frequently requires each specific nut to be labeled and handled distinctly. For example, a person may need to avoid cashew and pistachio only — and so a product label must indicate the presence not just of “tree nuts” but also detail which nuts are included. 

In some cases, specific allergen tests for each different tree nut can help provide this clarity. Testing incoming ingredients, surfaces, and finished products for the presence of almond, or walnut, hazelnut, macadamia, etc. is an important part of many food safety plans. In other cases, a simple protein swab may provide sufficient safety data.
However, running multiple test kits at once is expensive and time-consuming — and general protein swabs are neither sensitive nor specific to allergens. 
For these cases and many others, Microbiologique has developed the OnSite® Allergen Multiplex Tree Nut Rapid Test
The OnSite® Allergen Multiplex Tree Nut Rapid Test offers the sensitivity and specificity of an allergen LFD test with significant cost savings. It is suitable for food and beverage production facilities that work with one or several species of tree nut — and also for facilities that are entirely nut-free. 
Commercial kitchens and production facilities can easily meet their safety needs by incorporating this single test. Because OnSite® Allergen Multiplex Tree Nut Rapid Test identifies traces of almond, cashew, hazelnut, pecan, pistachio, and walnut, it offers flexibility for a variety of hazard scenarios. And because it requires no equipment or specialized training, it can be used anywhere that food is made.
