Lectin dosage

Why measure lectins?

Lectins are plant-derived proteins capable of binding specifically to carbohydrates. Found in many plants, particularly legumes (kidney beans, lentils, peas, soybeans), they can have antinutritional and potentially toxic effects when ingested in excessive quantities or insufficiently processed.

Lectin dosage is essential for:

• Controlling the quality and safety of legume-based products
• Verify the effectiveness of thermal or enzymatic treatments applied to plant-based raw materials
• Meeting regulatory requirements or standards of the agri-food or nutraceutical industry

Available analysis methods

Lectin analysis can be performed using several approaches, depending on the objectives and the matrix:

• Hemagglutination test: a standard biological method used to measure lectin activity by their ability to agglutinate red blood cells.
• ELISA method: targeted immunological detection of specific lectins (PHA, concanavalin A, etc.).
• HPLC or LC-MS: precise quantification after extraction, useful for complex formulations or transformed matrices.

Each method can be adapted according to the matrix, the pharmaceutical form, and the desired sensitivity.

Analyzed matrices

• Vegetable flours rich in legumes
• Plant extracts intended for use in food or supplements
• Raw or minimally processed products (powders, granules, dry ingredients)
• Animal feed (animal nutrition, rations based on soy or broad beans)

Industrial applications

Lectin assays are relevant to many sectors:

• Food industry: formulation of vegetarian, vegan, or allergen-free products
• Nutraceuticals: securing concentrated extracts, functional powders, plant-based supplements
• Animal nutrition: evaluation of raw materials rich in plant proteins
• Agronomic research: characterization of new plant-based food sources
