In Vitro Determination of the Allergenic Potential of Egg White in Processed Meat

الملخص EN

Hen's egg white has been reported as a causative agent of allergic reactions, with ovalbumin, conalbumin, ovomucoid, and lysozyme being the major allergens.

However, little is known about the effects of processing with heat and high pressure on the allergenicity of egg white proteins as ingredients in meat.

For this purpose, the allergenic characteristics of such treated preparations were studied.

The IgE-binding capacity was analyzed by EAST inhibition in raw and processed meat preparations using sera from patients with hen's egg specific IgE.

Increasing heat treatment as well as the application of high pressure decreased IgE binding, which is a measure of allergenic potential.

The combined application of heat (70∘C) and high pressure had synergistic effects in reducing the allergenic potential nearly twice as the sum of the single treatments conducted separately.
