(23 cards)
Duo-trio
Get X and A and B. Which sample is most similar to X?
A-not-A test
Get A and X. Is X the same or different than A.
Triangle test
Get A and B and A/B. Which one is the odd one out?
Same-difference test
Get A/B and A/B. Are the samples the same or different?
Reversed duo-trio test
Get A and B and X. Is X equal to A or B
Tetrad test
Get 2xA and 2xB, which are grouped together?
What is the difference from control test?
Measure the magnitude of difference on a scale
What is the two out of five test?
Get 5 samples. Group into 2 and 3 (specific attribute)
What is the Harris Kalmus test?
Get 8 samples. Group into 2x4 (specific attribute)
What is the paired comparison test?
Get two samples. Which is the most crunchy (specific attribute)
What is the 3-alternative forced-choice test?
Get three samples. Which is the odd one out (specific attribute)?
What is the texture profile method? What is it based on?
Based on flavor-profile method. Fixed vocabulary. Intensity scales labelled with references. Need high degree of training.
What is the spectrum method?
Texture profile method but with all sensory modalities
What is the flavour-profile method?
Trained panel discuss flavour attributes and come to consensus
What is the QDA?
A quantitative descriptive analysis based on flavor profile method. For all modalities. N=10-12. Attribute generation by panel beforehand. Only comparison.
What is the TI method?
Time intensity method. Trained panelists rate the intensity of one attribute over time.
What is the TDS?
Temporal dominance of sensations. Ask consumers which given attributes are the most dominant over time.
What is the TCATA method?
Temporal check all that apply method. Same as CATA but then over time.
What is the flash profile method?
Rank the intensity of own attributes and put in rank per attribute
What is the CATA method?
Check all that apply. Consumers check all attributes that apply.
What is the sorting method?
Put products in similarity groups (can add labels)
What is napping?
Very quick placement of products on a napkin according to similarities.
What is the paired preference test?
Get two samples and tell which one you prefer
