1. Assessment 1 Sensory Analysis

2. Question #1 Which test helps to find out whether Sample A or Sample B is sweeter? Paired Comparison Test Duo-trio Test Paired Comparison Test Duo-trio Test

3. Correct! In paired comparison tests, panellists are asked to say which of the two samples is sweeter, spicier, etc. It helps to confirm what a product developer might predict about the effect of modifying a food product. For example, reducing the fat content of a biscuit may make the end product more crumbly. Next Question Next Question

4. Think again! HINTS: There are only two samples: Sample A and Sample B. In duo-trio test, panellists are asked to choose the sample that matches the reference. Go BACK and choose the right answer Go BACK and choose the right answer

5. Question #2 A panel is asked to rate the taste level of cream, malt and nut in a chocolate sample. This test is called Quantitative Descriptive Analysis. True False False True

6. Correct! Descriptive tests are used to measure the type and intensity of particular attributes of a food product The test requires panellists to describe the product in terms of its characteristics and to measure the intensity of those characteristics and to measure the intensity of those characteristics using scaling methods Next Question Next Question

7. Think again! The answer should be TRUE Descriptive tests are used to measure the type and intensity of particular attributes of a food product Go BACK and choose the right answer Go BACK and choose the right answer

8. Questions #3 Which is an affective test? Duo-trio test Triangle test Hedonic test Duo-trio test Hedonic test Triangle test

9. Think again! HINTS: In triangle tests, the panellists are asked to choose the sample that is most different among three samples. It does not involve affection. Go BACK and choose the right answer Go BACK and choose the right answer

10. Think again! HINTS: In duo-trio tests, panellists are asked to choose the sample that matches the reference. It does not involve affection. Go BACK and choose the right answer Go BACK and choose the right answer

11. Correct! Hedonic test is used to measure how much people like a product. It is an affective test.
