From IEEE Spectrum:
Sundvor demoed the Nima testing process at the SXSW happy hour. First he placed a morsel of the dastardly chicken in a capsule and twisted the cap shut, which has the effect of grinding the food inside and releasing a solution to extract the protein. He then inserted the capsule into the triangular Nima, triggering the release of a chemical that reacts to gluten and creates marks on a paper test strip. That chemistry step takes about two minutes. Finally, a tiny optical sensor inside the device checked the strip and translated the information into a simple binary result: a smiley face or a frowny face.
