Evaluating the allergic risk of genetically modified soybean

Area of Science:

• Food science
• Allergology
• Biotechnology

Background:

• Genetically modified (GM) soybean is prevalent in Korea.
• Assessing the allergenic risk of GM foods is crucial.

Purpose of the Study:

• To compare the allergenicity and IgE-reactive components of wild-type and GM soybean extracts.
• To determine if genetic modification increases the allergenic risk of soybeans.

Main Methods:

• Recruited 1,716 allergic adults and 40 controls.
• Performed skin prick tests and IgE enzyme-linked immunosorbent assays (ELISAs).
• Utilized ELISA inhibition, 2D gel electrophoresis, IgE immunoblotting, and amino acid sequencing.

Main Results:

• Identical IgE sensitization rates (3.8%) to wild-type and GM soybeans.
• Comparable circulating IgE antibodies and similar IgE-binding components.
• No positive responses to purified EPSPS protein.

Conclusions:

• GM soybean extracts exhibit identical allergenicity to wild-type soybean extracts.
• Genetic modification does not alter soybean allergenicity in sensitized adults.
• No increased allergenic risk associated with GM soybean consumption.
