Sensory evaluation
For prototype product, sensory evaluation wasdetermined using a 9-point hedonic scale together with a 5-point ‘just about right’ scale. The hedonic scale ranged from 1, representing ‘extremely dislike’, to 9, representing ‘extremely like’. The ‘just about right’ scale ranged from ‘decrease very much’ to ‘increase very much’. Product was evaluated by 30 panelists in the characteristics of color, size, crispiness, Panang-flavor, saltiness, spiciness and overall liking. For product development, the 9-point hedonic scale was used with 30 panelists for the same sensory characteristics mentioned above. Samples were served in randomized order in a zip pack and coded with three random digits.
