Sensory evaluation texts recommended for judging a series of samples in order to preselect their quality and hedonic properties:

Correct option is A

Ranking tests are used in sensory evaluation to judge a series of samples based on their quality or hedonic (pleasure) properties. In this test, a panel of judges is asked to rank the samples in order from the best to the least preferred. These tests are useful for preselecting samples based on their sensory attributes, helping to determine the relative quality or preference for each sample.
Information Booster:
· Ranking tests are typically used when the goal is to compare several samples and identify the one with the highest preference or best quality.
· These tests are often used in hedonic studies (studying preferences), where the subjective experience of the tester is more important than objective measurements.
Additional Knowledge on Incorrect Options:
· (b) Duo-trio tests: In this test, the judge is given two samples (one of which is a reference) and is asked to identify the sample that is different from the reference. This test is more about discrimination than about ranking or hedonic properties.
· (c) Triangle tests: In this test, a panelist is given three samples (two are identical and one is different) and must identify the odd sample. This is also a discrimination test rather than a hedonic evaluation.
· (d) Threshold tests: These tests are designed to determine the minimum detectable level of a sensory stimulus, such as the lowest concentration of a flavor or aroma that can be perceived. They are not used for hedonic evaluation or ranking.
