Peanut does not have an FDA determined limit for “safe” levels in foods, so we designed our test to detect at the lowest part of the range for LOAEL (lowest-observed- adverse-effect level).
LOAEL is a safety assessment-based approach, based on clinical data linked to biological effects. LOAEL for peanut ranges from 0.25 to 10 mg of protein. The lowest part of this range corresponds to 10 parts per million (ppm) for a standard serving size of 100 grams. We wanted to target detection at the lowest level that is believed to cause a reaction so the peanut sensor will detect peanut at 10 ppm and above with extreme accuracy.
