Food Safety & Allergens


Here at Adamson Analytical, we can test your samples for the presence of food allergens and other contaminants in order for you to meet FDA compliance. We can identify the presence of milk, egg, fish, shellfish, tree nuts, peanut, wheat or soy in a sample as well as quantitative analysis to determine the concentration of allergen in a sample, or whether or not an allergen is present in a sample. Concentrations as low as 5 ppm can be detected.

Procedure Summary

Food samples are tested for allergens using the ELISA (Enzyme-Linked Immunosorbent Assay) test. Samples and controls are added to special antibody-coated wells which react to specific antigens present in the sample. For example, an egg product contains albumin. Milk products contain casein, lactoglobulin, etc. Detector antibody and substrates are added to each well so that allergen levels can be measured. Optical readings for the samples are then compared to control readings to determine allergen concentration.


Food Allergen Labeling and Consumer Protection Act of 2004
