Lectin dosage

Why measure lectins?

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

Lectin dosage is essential for:

• Control the quality and safety of legume products
• Check the effectiveness of thermal or enzymatic treatments applied to plant raw materials
• Meet 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 for measuring the activity of lectins 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 galenic form, and the desired sensitivity.

Analyzed matrices

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

Industrial applications

Lectin dosage concerns many sectors:

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