Lentil allergens identification and quantification: An update from omics perspective

Area of Science:

• Food Science
• Allergology
• Proteomics

Background:

• Lentils (Lens culinaris) are a nutritious legume, but lentil allergies are increasingly reported globally.
• Previous research identified major lentil allergens like Len c 1 (vicilin), Len c 2, and Len c 3 (lipid transfer proteins).
• Comprehensive allergen profiling is essential for managing lentil food allergies effectively.

Purpose of the Study:

• To discuss the application of omics platforms for lentil allergen profiling and quantification.
• To propose future strategies for precise lentil allergen identification and assay development.
• To facilitate the identification of lentil cultivars with reduced allergen content.

Main Methods:

• Utilizing mass-spectrometry-based proteomic platforms to identify lentil proteins homologous to known plant allergens.
• Employing in silico analysis of 337 protein sequences to discover novel potential lentil allergens.
• Reviewing the feasibility of omics technologies for allergen analysis.

Main Results:

• Mass spectrometry successfully identified known and novel lentil allergens.
• In silico analysis revealed previously unidentified potential lentil allergens.
• Omics platforms show promise for comprehensive lentil allergen profiling.

Conclusions:

• Omics technologies offer powerful tools for detailed lentil allergen characterization.
• Further research and precise assays are needed for accurate lentil allergen detection.
• Identifying low-allergen lentil varieties is a key goal for food allergy management.
