Peanut proteins

Peanut proteins are the proteins found in peanuts, dominated by arachin, conarachin I, and conarachin II. They are responsible for peanut allergenicity, triggering reactions that can be severe, which is why peanut labeling is strictly enforced worldwide. In food science, these storage proteins also provide nutritional value and functional properties such as emulsification in peanut-based products. Processing like roasting alters their structure and may affect allergenic potency, an active research area. For manufacturers, controlling cross-contact with peanut proteins is a central allergen-management challenge. Understanding their identity and behavior underpins both safer products and clearer communication with allergic consumers.
