7.3.19 Sensory evaluation
The sensory evaluation of the beverage, biscuits, cooked noodles and granola bars was
done by using self-provided questionnaires, on which the test persons assessed the
products on a 10-cm linear scale. For each product, 15 untrained persons were
questioned about appearance, odour, taste, texture and overall impression with
attributes like sweetness, crispness, creaminess, off-taste or hardness. The test
persons did not get detailed information about the samples, which were provided with
a three digits numerical code. For the evaluation, the individual lines on the scale were
measured and statistical analyses were done. The higher the reached score, the higher
was the acceptance of the consumers. From fig. 9 to fig. 12 the different tasting sheets
are shown.
