Sesame: addressing a growing food allergen

Uses and regulatory requirements

Sesame seeds (Sesamum indicum) are widely used, either raw or roasted, in pastries, ice cream, cereals, chocolate, and for producing oil or paste. Labeling sesame as an ingredient is mandatory in the European Union, Canada, and Australia.

Increasing prevalence of sesame allergy

Sesame allergy is becoming more common as the consumption of sesame increases, driven by the rise in healthy lifestyle and nutrition awareness. Sesame is also popular in vegetarian diets. This allergy can cause severe symptoms, including anaphylactic shock. The only effective way to protect sensitized individuals is through strict avoidance of sesame-containing foods. Consequently, sesame must be labeled on prepackaged foods in the EU, Canada, and Australia, as it is included in their lists of major allergens.

Allergenic proteins in sesame

Seven different proteins in sesame have been identified as allergens (Ses i 1-7). These proteins can trigger severe allergic reactions, making accurate labeling and avoidance essential for those with sesame allergies.

Cross-contamination risks and the need for testing

Sesame can be found in various foods, including bakery products, baking mixes, cookies, chocolate, and desserts. In production facilities where sesame-containing and sesame-free foods are processed on the same lines, there is a risk of cross-contamination. This makes it necessary to analyze these foods to ensure they are free from unwanted sesame contamination, thereby safeguarding allergic consumers.

Key benefits of monitoring sesame allergens

• Consumer safety: Protects individuals with sesame allergies from potentially severe allergic reactions by ensuring accurate detection and labeling of sesame allergens in food products.
• Regulatory compliance: Helps manufacturers comply with food allergen labeling regulations in the EU, Canada, Australia, and other countries, ensuring that all sesame-containing products are properly labeled.
• Quality assurance: Maintains the integrity and safety of food products by accurately identifying and quantifying sesame allergens, preventing accidental exposure.
• Cross-contamination prevention: Ensures that food production environments are free from sesame allergens, preventing cross-contamination and ensuring the safety of allergen-free products.
• Advanced detection methods: Utilizes highly specific and sensitive detection techniques, such as real-time PCR, to accurately detect and quantify sesame traces, even in processed foods.

Conclusion

Monitoring for sesame allergens is essential for protecting consumer health, ensuring regulatory compliance, and maintaining product quality. By employing advanced detection methods such as real-time PCR, manufacturers can accurately identify and quantify sesame contamination, preventing allergic reactions and ensuring the safety of their products. This proactive approach supports robust allergen management, upholds food safety standards, and fosters consumer trust in sesame-free products.
