What it is

Nut shell fragments are small pieces of the hard outer covering of nuts. They are a byproduct of nut processing, such as shelling and grinding. These fragments are typically removed during food production but can sometimes remain as incidental contaminants.

Why it's used

Nut shell fragments are not intentionally added to foods for a specific function. Their presence is usually accidental, resulting from the processing of nuts. They are most likely to be found in baked goods where nuts are a common ingredient.

Health notes

Nut shell fragments are not a regulated food additive. Their presence in food is generally considered incidental. Regulatory bodies like the FDA monitor for excessive levels of incidental contaminants to ensure food safety. While not a major health concern at low levels, high concentrations could pose a physical hazard.

Allergen info

Nut shell fragments are derived from tree nuts, which are one of the 9 FDA major allergens. Therefore, they can pose a risk to individuals with tree nut allergies.
