3.5.3.2 Sensory testing methods and setting up a taste panel Quiz: AQA Food Preparation and Nutrition, Unit 4

The 20 questions

1. Which sensory test asks participants to choose which of two samples they prefer?

   • Profiling test, which scores separate characteristics
   • Ranking test, which orders several samples
   • Paired preference test
   • Triangle test, which asks for the odd sample out

2. Which sensory test asks participants to identify the odd sample out of three?

   • Hedonic test, which measures how much a product is liked
   • Rating test, which scores the intensity of an attribute
   • Paired preference test, which asks which sample is preferred
   • Triangle test

3. Which type of test asks participants to rate how much they like a product on a scale?

   • Discrimination test, which checks for a detectable difference
   • Paired comparison test, which picks one of two samples
   • Hedonic test
   • Triangle test, which checks whether samples are different

4. Which grading test asks participants to put samples in order from best to worst?

   • Aroma test, which judges only the smell of samples
   • Triangle test, which identifies the odd sample
   • Paired preference test, which compares two samples
   • Ranking test

5. Which grading test breaks a food down into its separate sensory characteristics?

   • Hedonic test, which measures overall liking on a scale
   • Triangle test, which finds the odd sample out
   • Profiling test
   • Paired preference test, which compares two samples only

6. Which controlled condition is important when setting up a taste panel?

   • Samples are labelled with their price so panel members can compare
   • Samples are served in different coloured cups to show their brand
   • Samples are presented in identical containers with random three-digit codes
   • Samples are tasted in a noisy room with bright lights and music

7. Why should a taste panel be given water between samples?

   • To remove the colour from the samples before the panel begins tasting them
   • To clear the palate so that the next sample is tasted fairly
   • To help the samples cool down more quickly on the table
   • To make the samples taste sweeter when they are tasted

8. Which factor is important for a taste panel to be reliable?

   • Participants should be asked to talk during each test
   • Participants should be untrained and tested in the same conditions
   • Participants should taste the samples in a random order of expertise
   • Participants should all know the brand of each sample being tasted

9. A panel is asked to decide whether two samples are different. Which test is being used?

   • A profiling test, which scores separate characteristics
   • A hedonic test, which measures how much a product is liked
   • A discrimination test
   • A ranking test, which orders several samples

10. Which feature of a taste panel helps keep results valid when many samples are compared in one session?

    • Using a different number of samples for each member
    • A consistent order and a rest period between samples
    • Tasting all samples at the same time from one shared plate
    • Letting panel members discuss each sample before scoring

11. Which sensory test is used to show whether a person can tell two batches of a sauce apart before any preference is asked?

    • A discrimination test such as the triangle test
    • A profiling test of texture, which scores separate characteristics
    • A hedonic rating test, which measures overall liking
    • A ranking test of colour, which orders samples by appearance

12. Why is it important to serve samples at the same temperature in a taste test?

    • So that the panel can eat more quickly through the samples
    • So that temperature does not change how the taste is judged
    • So that the samples look more appetising on the serving tray
    • So that the samples are cheaper to produce in the kitchen

13. A panel member is asked to describe the crunchiness and sweetness of a biscuit on a scale. Which test is this?

    • A discrimination test on price, which compares cost
    • A triangle test, which finds the odd sample out
    • A profiling or rating test
    • A paired preference test, which asks which sample is liked

14. Which statement about a triangle test is correct?

    • Participants rank all samples from best to worst on one scale
    • Participants describe the colour of each sample in their own words
    • Participants identify the different sample from three, which tests discrimination
    • Participants buy the sample they like most at the end of the test

15. Why should panel members not be told which product is which before a test?

    • Knowing the brand can bias the judgement of taste
    • Knowing the brand stops the samples from being tasted at all
    • Knowing the brand changes the temperature of the samples
    • Knowing the brand changes the sweetness of the food being tasted

16. Which controlled condition helps reduce distractions during a sensory test?

    • Individual booths with good lighting and no background noise
    • A room with strong perfume in the air from the cleaning products during the test
    • A hot kitchen with steam rising from pans during tasting
    • A crowded room with loud music playing in the background

17. Which test asks panel members to score how intense a particular attribute is?

    • A discrimination test, which checks for a detectable difference
    • A rating test
    • A paired preference test, which picks one of two samples
    • A triangle test, which finds the odd sample out

18. A taste panel uses a sample coded with the letters 'XQ7'. What is the purpose of this coding?

    • To show the price of the sample to the panel members
    • To show the use-by date of the sample on the label
    • To show the country where the sample was grown and made
    • To keep the test blind so that the sample is judged without bias

19. Which action is most important when setting up a sensory test for a product?

    • Telling every panel member the expected result before the test
    • Standardising how the samples are prepared and served to every panel member
    • Serving samples in mixed sizes to add variety to the test
    • Making each sample using a different recipe for variety

20. What is the main purpose of a hedonic test?

    • To rank samples by how strong one flavour is
    • To check whether the panel can smell a difference
    • To measure how much people like or dislike a product
    • To find the odd sample out in a set of three samples
