Tree Nuts: Comprehensive allergy testing solutions

Prevalence and importance of tree nut allergies

Tree nut allergies are among the most common food allergies, affecting approximately one percent of the population. These allergies can cause severe reactions, making accurate detection and labeling crucial for consumer safety.

Definition and allergenicity of tree nuts

The term “tree nuts” refers to nuts that grow on trees, distinguishing them from peanuts, which grow underground and are technically legumes. Not all tree nuts have the same level of allergenicity. For example, hazelnut allergies are particularly widespread, while almonds or coconuts are often better tolerated. Allergy tests can help determine which tree nuts are safe for consumption for individuals with nut allergies.

Regulatory requirements for tree nut labeling

Tree nuts must be declared as ingredients on food packaging according to EU Directive 2007/68/EC, as they are among the most significant allergens. However, cross-contamination can occur in both nut-processing and nut-free facilities, particularly during the production of confectionery, baked goods, chocolate, cookies, cereals, or ice cream. To mitigate this risk, some manufacturers include disclaimers such as “May contain traces of nuts” on their products.

Ensuring nut-free products

For individuals with nut allergies, it is vital to trust that a product labeled as “nut-free” truly contains no nut allergens. Therefore, thorough examination of production areas and end products is essential. R-Biopharm AG offers a comprehensive range of test kits to detect various types of nuts, ensuring the highest standards of food safety.

R-Biopharm AG test tits for tree nuts

Our portfolio includes test kits for detecting the following types of nuts:

  • Almond
  • Brazil nut
  • Cashew
  • Coconut
  • Hazelnut
  • Macadamia
  • Pecan
  • Pistachio
  • Pine nut
  • Shea nut
  • Walnut

Screening strategy for tree nuts using multiplex PCR

We provide a robust screening strategy starting with a broad screening for the eight relevant tree nuts and peanuts, in compliance with directive (EC) 1169/2011. Positive results can be further identified with one of our three multiplex nut kits if needed. Quantification is also possible using SureFood ALLERGEN identification and quantification kits.
