Soy free testing verifies the absence or presence of soy protein in food products, cosmetics, and formulated consumer goods. Pentyl Labs performs this testing using enzyme-linked immunosorbent assay (ELISA) methods designed for sensitive and specific soy protein detection.
Soy is a widely used ingredient derived from soybean oil, lecithin, and protein fractions. However, soy is also a major food allergen. Because of this, manufacturers often need analytical confirmation to support allergen control programs, ingredient verification, and “soy-free” product claims.
ELISA testing targets soy proteins using antibodies that provide strong specificity. This approach allows detection at very low levels, even in complex product matrices. As a result, soy free testing is suitable for finished products, raw materials, and in-process samples.
Manufacturers commonly request soy testing during formulation development, supplier qualification, and routine quality assurance. Testing also supports investigations related to cross-contact, shared equipment, or raw material changes. When soy protein is detected, results help guide corrective actions and risk management decisions.
Soy free testing applies to a broad range of products, including foods, dietary supplements, cosmetics, personal care items, and other formulated goods. In cosmetics, soy derivatives may be present through botanical extracts, emulsifiers, or processing aids. Testing helps confirm label accuracy and supports internal safety documentation.
This analysis supports allergen management programs and regulatory compliance. Many global regulations require accurate allergen disclosure when soy is present above trace levels. Analytical data from ELISA testing helps manufacturers document compliance and prepare for audits or customer reviews.
Soy free testing is often included within broader Allergen Testing Services and Chemical Analysis Services. Guidance from regulatory authorities such as the U.S. Food and Drug Administration (FDA) defines allergen labeling and control expectations used during testing programs.
Overall, soy free testing provides reliable data that helps manufacturers protect consumers, maintain label accuracy, and support confident product release across multiple industries.
