Tree nuts
The nut allergy is one of the most common food allergies. Approximately one percent of the population has an allergic reaction to nuts.
The term “tree nuts” refers to nuts which grow on trees and is not to be mistaken with peanuts (which grow underground and are actually not considered a “nut”). Not all types of nuts have the same level of allergenicity. For example, hazelnut allergy is particularly widespread, whereas almonds or coconuts are often better tolerated. An allergy test provides insight into which tree nuts can and cannot be consumed by the persons concerned.
Tree nuts must be indicated as an ingredient on packages according to EU Directive 2007/68/EC because they are ranked among the most important allergens. However, nuts can accidentally enter a food due to cross contamination. The accidental contamination can occur in companies that process food that contain nuts as well as those that are nut-free. This can occur, for example, during the production of confectionery, baked goods, chocolate, cookies, cereals or ice cream. Some manufacturers protect themselves by providing their products with the following disclaimer: “Can contain traces of nuts.”
For allergy sufferers it is important to be able to rely on the fact that a food product is actually free of nuts if it is declared as “nut-free.” Therefore, it is necessary to carefully examine the production areas as well as the end products. For this purpose, we offer a comprehensive portfolio of test kits for various 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
Starting with a broad screening for the 8 relevant tree nuts as well as peanut according to directive (EC) 1169/2011 in food. Positive results can be further identified with one of our three multiplex nut kits, if needed. A quantification is also possible using SureFood ALLERGEN identification and quantification kits.
