What are allergens? Everything you need to know

Allergens are substances that can trigger allergic reactions in the human body, ranging from mild symptoms to severe responses that require emergency medical intervention. In a world where food safety and transparency are essential, it is important to understand what allergens are, how they can affect health, and how to manage them effectively — especially if you work in the HoReCa industry.

1. Gluten

Gluten is a protein found in wheat, barley, and rye. People with celiac disease or gluten sensitivity may experience severe digestive symptoms, such as bloating and diarrhea. It is essential to avoid gluten-containing foods to prevent adverse reactions.

2. Crustaceans

Shrimp, crabs, and lobsters are common causes of severe allergic reactions. Individuals allergic to crustaceans may experience anaphylactic shock, even from trace amounts.

3. Fish

Another common allergen, fish can trigger mild to severe reactions. Allergies are often linked to species such as tuna, cod, or salmon.

4. Peanuts and Tree Nuts

This includes almonds, cashews, and pecans, which are well known for their potential to trigger severe allergic reactions, including anaphylaxis. Even a small amount can cause a serious response, making complete avoidance essential.

5. Soy

Soy is commonly found in processed foods and vegetarian alternatives. Soy allergies can cause a variety of symptoms, from skin rashes to respiratory issues.

6. Lactose

Lactose is the natural sugar found in milk and dairy products. Lactose intolerance occurs when the body does not produce enough lactase, the enzyme required to digest lactose, leading to digestive discomfort.

7. Eggs

Eggs are a frequent ingredient in many dishes and can cause allergic reactions in some individuals. Symptoms may include hives and respiratory problems, and in severe cases, anaphylaxis.

8. Sesame

Sesame seeds are commonly used in baked goods and seasonings. Sesame allergies can lead to reactions that range from mild to severe.

9. Lupin

Lupin is used in baked goods and processed foods, which is why it is important to check labels to avoid accidental exposure.

10. Mustard

Commonly found in sauces and condiments, mustard is classified as an allergen and may cause anything from mild discomfort to severe allergic reactions.

11. Sulphites

Sulphites are food additives used to preserve freshness. Sensitive individuals may experience respiratory symptoms and other allergic reactions when exposed to sulphites.

How can allergens be managed in the food industry

Managing allergens is critical in the food industry to prevent serious allergic reactions. Here are several essential strategies:

Clear Labeling

Ensure all products are correctly labeled, clearly indicating the presence of allergens. This helps consumers make informed decisions.

Ingredient Separation

Use separate equipment and preparation areas to avoid cross-contamination between allergenic and non-allergenic ingredients.
