Sensory analysis uses different tests to understand consumer preferences and ability to discriminate between products. Preference tests gather opinions on how much consumers like or dislike samples using hedonic or paired testing. Discrimination tests determine if consumers can detect differences between samples using paired comparisons to evaluate specific qualities or triangle tests to identify the odd sample out of three options.

1. Sensory Analysis A view of different tests

2. Preference Test All about product acceptability Opinions Likes and dislikes 2 types: Hedonic – give opinions on samples from ‘extreme like’ to ‘extreme dislike’. Paired – 2 samples indicate which they prefer.

3. Discriminatory Tell the difference between samples

4. Paired comparison Pair of coded samples given for specific comparison of a quality e.g. sweetness, crunchiness.

5. Triangle Test 3 samples are given, 2 are the same and 1 is difference. Have to spot the odd one out.
