Automated reading and recording of sensory data for semi-structured scales

Abstract The use of Optical Mark Reader (OMR) cards is proposed, explained and tested as a potential substitute for the conventional semi-structured scale used in sensory evaluation. The use of OMR cards allows the direct transfer of data from the panelist to the computer, bypassing the tedious measuring, recording and data entry steps normally required. Statistical assessment of the OMR method in relation to the semi-structured approach indicates that comparable results can be obtained.
