Soy Processing and Food Allergy

Soy allergies are widespread and are becoming increasingly significant today as people around the world consume more and more soy and soy-containing foods. Soy is used in many products and undergoes various processing steps such as heating, extraction, enzymatic degradation, and preservation. However, it is not yet fully understood how these processing steps affect soy's ability to trigger allergic reactions. The goal of this project is to process soy in various controlled ways and investigate how these methods affect its allergenic potential. First, the effects will be tested in the laboratory (in vitro). Subsequently, the results will be examined in humans using a skin prick test (SPT) to determine how the processed soy affects allergic reactions

Soy allergies are widespread and of particular concern, as the consumption of soy and soy products is increasing worldwide. Soy is processed in various ways for many foods, such as through heating, extraction, hydrolysis, and preservation. To date, little is known about the extent to which these processing steps influence the allergenicity of soy. In this open-label, non-randomized, comparative, prospective, single-center clinical study, we aim to investigate the effects of the aforementioned processing steps on allergenicity. The project consists of various modules. The experimental parts will examine how soy can be modified through the processing steps mentioned above and how these steps can be integrated into the production of soy products. In the clinical part, the allergenicity of the modified soy products will first be tested in vitro and subsequently in skin tests.
