Relationship between the risk for a shrimp allergy and freshness or cooking

Tropomyosins are defined as risk factors for shrimp allergy. However, their concentration in different preparations has not been clarified. We quantified the tropomyosin concentration in shrimp meat, which was cooked using several methods or was stored under various conditions. The results demonstrated that shrimp meat from various preparations and storage conditions maintained tropomyosin concentrations that were sufficient to cause food allergies.
