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.
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.
The FDA requires food manufacturers to list common food allergens on labels in simple terms adults and older children can understand. While not every possible food that can cause a food allergy is listed, “products containing any of these eight major food allergens have labeling requirements: Milk, Egg, Fish, Shellfish, Tree Nuts, Peanut, Wheat, Soy
