Eurofins Technologies, a supplier of test kits and systems for laboratory analyses, announces the launch of its SENSISpec Soy Total protein ELISA kit, an enzyme immunoassay for the quantitative detection of soy protein in food and swab samples.

The development of the assay has been performed by Eurofins Immunolab, a biotechnology company with a wide experience in food allergen analysis and part of Eurofins Technologies group.

Soy is one of the “Big Eight” allergens, along with cow’s milk, eggs, peanuts, tree nuts, wheat, fish, and shellfish. These are responsible for 90 percent of all food allergies, which in severe cases may lead to anaphylactic shock. Management of food allergies implies the elimination of the allergen from diet, requiring labeling and traceability throughout the food production process, from raw material to the final product.

Soybeans belong to the legume family, and they are found in many unexpected, processed foods, such as condiments, flavouring, meat substitutes, frozen meals, etc. Consequently, a sensitive detection systems for soy residues in food¬stuffs is required.

Some of the currently existing kits in the market detect the Soy Trypsin Inhibitor, which implies some limitations, as the use of conversion factors to obtain the final value in Total Soy Protein.

For this reason, the Immunolab Soy Protein Total ELISA is based on antibodies raised against hydrolyzed soy protein, which represent the most variety of manufacturing processes. As such, it is a suitable assay for the quantification of processed protein residues in baby food, cookies, cereals, ice cream, chocolate, instant meal and sausage. As an additional advantage, compared with competitors ELISA kits for processed soy detection, the assay shows no cross-reactivity with any other legumes.

The kit is provided in both, 96 and 48 wells format, and includes all necessary reagents. With a Limit of Quantification of 2 ppm, it is one of the most sensitive kits in the market, creating additional safety for consumers with soy allergy. This new and enhanced kit is a key component of Eurofins Technologies allergen management product line, which covers a very comprehensive range of parameters; and demonstrates Eurofins Technologies’ commitment to providing high quality, and valuable test methods for our food safety customers.
