Food allergy research has shown that the majority of individuals that have a negative reaction to soy are reacting to soy protein found in soybeans. Soy oil and soy lecithin do not contain soy protein.Because of this, some individuals are able to consume soy oil and soy lecithin without an allergic reaction. Of course, the degree and severity of an allergic reaction varies with each individual.ithout an emulsifier, the cocoa and cocoa butter would separate. One reason soy lecithin makes a frequent appearance on our candy bar (and other) food labels as an emulsifier is due to its low cost. Soybeans are one of the least expensive crops grown in America.
Soybeans are well-recognized as allergenic foods. The soybean allergens are found in the protein fraction. The vast majority of this protein is removed in the soy lecithin manufacturing process. Soy lecithin does contain trace levels of soy proteins and these have been found to include soy allergens.any allergists do not even advise their soybean-allergic patients to avoid soybean lecithin when it is included as an ingredient on food products. From this practical standpoint, we can surmise that most soybean-allergic individuals do not react adversely to the ingestion of soybean lecithin.
