Odor Bag

Triangle odor bag method for odor sensory measurement is a measurement using calculation formula of odor index related to dilution of sample concentrations. The sensory test is conducted by at least 6 members of the panel. Each panel is given 3 bags; 1 with a sample in it and 2 without sample (odor-free air) and asked to choose the odorous bag. If the panel can tell the correct bag, the odor is then diluted and the test is continued until it becomes impossible to identify the bag with odor.

This method is conducted by three steps: (1) selection of panels, (2) Sampling, (3) Sensory test.
GL sciences provide tools following these procedures.
