What is the Bloom Test?
A Named after its inventor, the Bloom Test involves a device that measures the rigidity of a gelatin film. A sample of gelatin is prepared with standard proportions of water and gelatin. The sample is processed according to an exacting test protocol, and compressed using plunger moving a specified depth into the test gel. The force required to reach a predetermined depth is expressed as “Bloom strength” or simply “Bloom.” Higher Bloom indicates stronger gel and increased clarity.
