Prospects for developing allergen-depleted food crops.

Area of Science:

• Food Science
• Immunology
• Agricultural Biotechnology

Background:

• Rising global food demand and modern lifestyles increase exposure to common food allergens like peanuts, tree nuts, wheat, and soy.
• Food allergies, triggered by specific proteins, pose significant health risks, with prevalence increasing despite suboptimal detection and treatment standards.
• Key allergens include those from peanuts (Arachis hypogaea), tree nuts, wheat (Triticum aestivum), soybeans (Glycine max), and kidney beans (Phaseolus vulgaris).

Purpose of the Study:

• To review the prevalence and characteristics of allergies to peanut, tree nuts, wheat, soybean, and kidney bean.
• To explore research directions for tailoring allergen gene expression in food crops.
• To discuss the application of modern breeding techniques for developing low-allergen food varieties.

Main Methods:

• Literature review focusing on prevalence, physiological properties, and functions of major food allergens.
• Analysis of recent advances in molecular breeding, genetic engineering, and genome editing technologies.
• Discussion of potential strategies for modifying allergen gene expression in crops.

Main Results:

• Peanuts are the most characterized allergen source, followed by tree nuts, wheat, soybeans, and kidney beans.
• Significant increase in food allergy prevalence and accidental exposure incidents observed.
• Current diagnostic and therapeutic standards for food allergies remain suboptimal.

Conclusions:

• Developing low-allergen food crops through genetic approaches is a promising strategy to protect consumer health.
• Tailoring allergen gene expression holds potential for mitigating allergic reactions.
• Further research into molecular breeding and genome editing is crucial for creating safer food supplies.
