Allergen extraction: Factors influencing immunogenicity and sensitivity of immunoassays.

Food allergy prevalence is increasing worldwide, therefore there is a high demand for reliable tests to correctly diagnose this disease. Knowledge of proteins allergenicity and how they react both in the body and in diagnostic tests is necessary to adequately assess the potential immunogenicity of both natural foods and those produced through biotechnological processes. Thus, our aim was to analyze the factors that influence the protein extraction of foods in terms of, immunogenicity and immunoassays sensitivity.

Induction of food tolerance is dependent on intestinal inflammatory state.

Food allergies are usually managed by food avoidance. Hidden allergens in food, due to cross-contamination and/or allergenic additives added during production, place an important concern in today's increasing food allergy cases worldwide. Previous studies showed that the introduction of unacquainted food components, in an inflamed intestine, results in sensitization to this food.
