Potential Transfer of Toxic Gluten from Biodegradable Tableware to Gluten-Free Foods: Implications for Individuals with Gluten-Related Disorders
The increasing use of biodegradable food-contact materials poses a risk for individuals with gluten-related disorders, including celiac disease. Tableware manufactured from wheat or other cereal derivatives may retain gluten proteins; regulations do not mandate allergen labeling. This study evaluate...

| Sumario: | The increasing use of biodegradable food-contact materials poses a risk for individuals with gluten-related disorders, including celiac disease. Tableware manufactured from wheat or other cereal derivatives may retain gluten proteins; regulations do not mandate allergen labeling. This study evaluated gluten transfer from eight commercial biodegradable items to representative gluten-free foods under realistic conditions. Gluten was quantified in biodegradable tableware and food samples after contact, using monoclonal antibody-based assays (G12 and A1) which detect gluten immunogenic peptides (GIP), providing a sensitive measure of potential immunological risk. Only one wheat-derived dish contained gluten and transferred it into solid and liquid foods. Migration was greater in liquid foods, particularly emulsified systems. In several cases transferred gluten exceeded the 20 mg/kg threshold for gluten-free labeling. Heat and prolonged exposure increased transfer. These findings highlight a critical regulatory gap, underscoring the urgent need for mandatory allergen labeling on biodegradable tableware to protect vulnerable consumers. |
