Question

Which sensory method provides quantitative description of sensory attributes using trained panelists?

• A. Hedonic test
• B. Difference test
• C. Descriptive analysis
• D. Ranking test

Hint:

Trained panels are used for descriptive analysis, while untrained/consumer panels are used for hedonic (preference) testing.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks for the sensory evaluation method that produces a detailed, quantitative profiling of multiple sensory characteristics of a food product using trained evaluators.

Step 2: Key Formula or Approach:
Sensory evaluation methods are divided into three main classes: discriminative (difference testing), affective (preference/consumer testing), and descriptive (analytical profiling).

Step 3: Detailed Explanation:

• Descriptive Analysis: Highly trained panels (typically consisting of 8 to 12 members) are used to identify, describe, and quantitatively evaluate the intensity of sensory descriptors (aroma, texture, flavor, appearance) on a structured scale. Examples include Quantitative Descriptive Analysis (QDA).

• Hedonic test: An affective test that utilizes a large, untrained consumer panel to rate product acceptability and liking.

• Difference test: A discriminative test (such as a triangle or duo-trio test) used to determine if a perceivable difference exists between two samples.

• Ranking test: A simple sorting test in which panelists arrange samples based on the perceived intensity of a single attribute or general preference.

Step 4: Final Answer:
Thus, descriptive analysis is the sensory method that provides a quantitative description of sensory attributes.
