Gluten testing in grains

Introduction

Gluten testing is an essential practice in the food industry, particularly for those with gluten-related disorders such as celiac disease. This protein, found in various grains, can lead to serious health issues for sensitive individuals. This article explores the significance of gluten testing, the methods used, and its implications for consumers and manufacturers alike.

What is gluten?

Gluten is a group of proteins primarily present in certain grains that provide elasticity and structure to dough. The main grains containing gluten include:

Grains that contain gluten:

• Wheat (including all varieties, such as spelt, durum, and einkorn)
• Barley
• Rye
• Triticale (a cross between wheat and rye)

Health effects of gluten

While gluten is harmless for most people, it can trigger severe reactions in those with celiac disease, an autoimmune disorder that damages the small intestine upon gluten ingestion. Common symptoms associated with gluten sensitivity include:

• Diarrhoea
• Bloating
• Fatigue
• Unintentional weight loss
• Anaemia
• Nutritional deficiencies

Importance Of Testing Gluten In Grains

Medical Significance

• Celiac Disease Management: Testing for gluten is crucial for diagnosing and managing celiac disease, helping individuals avoid gluten and mitigate adverse health effects.
• Non-Celiac Gluten Sensitivity (NCGS): For individuals without celiac disease but experiencing symptoms related to gluten consumption, testing can help identify their sensitivities.

Regulatory Compliance

• Labelling Accuracy: Proper gluten testing ensures that food products are accurately labelled, adhering to regulatory standards, and helping consumers make informed choices.
• Gluten-Free Certification: Many certification programs require stringent testing to confirm that products meet specific gluten content criteria.

Consumer Safety and Trust

• Allergen Awareness: Testing enhances consumer awareness regarding allergens, enabling them to avoid accidental gluten exposure.
• Product Reliability: Consistent testing builds consumer confidence in products labelled as gluten-free.

Industry Implications

• Cross-Contamination Prevention: In facilities that process both gluten-containing and gluten-free products, testing is vital to prevent cross-contamination.
• Research and Development: Accurate gluten measurements support the development of new gluten-free products.

Standards and Regulations

FSSAI

• Gluten Limits: Under FSSAI guidelines, products can be labelled as "gluten-free" if they contain 20 mg/kg or less of gluten. This standard aligns with international norms, including those set by Codex Alimentarius.
• Labelling Requirements: The term "gluten-free" must be prominently displayed near the product name on packaging. FSSAI is also working on provisions to address cross-contamination issues.

European Union Regulations

Commission Implementing Regulation (EU) No 828/2014

• Purpose: This regulation establishes harmonized requirements for labelling food products as "gluten-free" or "very low gluten."
• Gluten Limits: Foods labelled as "gluten-free" must contain no more than 20 mg/kg of gluten, while "very low gluten" products can contain between 20 mg/kg and 100 mg/kg.
• Scope: The regulation applies to both pre-packaged and non-pre-packaged foods, including those served in restaurants, expanding consumer protection for those with gluten intolerance

Mandatory and optional analysis

Eurofins role in testing gluten in grains

Eurofins Scientific plays a significant role in testing gluten in grains, providing comprehensive analytical services to ensure compliance with food safety regulations. Here are the key aspects of Eurofins' involvement in gluten testing:

Testing Services Offered by Eurofins

• Total Gluten Content Analysis: Eurofins conducts tests to measure the total gluten content in various grain samples. This is crucial for determining whether products can be labeled as "gluten-free," adhering to the regulatory limit of 20 mg/kg set by both the EU and FSSAI.
