2.7. Sensory evaluation
A reference sample and seven coded samples of cotton seeds fermented traditionally and under controlled condition were given out to 30 panellists in a ventilated and well-lit room to ensure proper sensory evaluation, and grading of the samples by the panellists was done using the 9-point hedonic scale. Preference test was conducted on the data collected from the questionnaire using the multiple comparison test (Larmond, 1977). All data collected were analysed using the Analysis of Variance with means separated using Duncan’s Multiple Range test.
