3.5.3.1 Sensory Testing Methods

• What is the scientific discipline used to measure and analyze human perception of food characteristics?

  Sensory evaluation
• Objectivity in sensory evaluation involves minimizing personal biases through standardized procedures.
• The Triangle Test identifies which of three samples is different
• What does the Hedonic Scale measure in sensory evaluation?

  Preference or liking
• Consistency in sensory evaluation requires conducting evaluations under controlled conditions.
• The Triangle Test is used to compare new and existing products
• Which sensory testing method orders samples according to a particular attribute?

  Ranking
• Match the sensory testing method with its description:

  Triangle Test ↔️ Identifies which of three samples is different from the other two

  Paired Comparison ↔️ Determines which of two samples has a stronger characteristic

  Hedonic Scale ↔️ Measures preference or liking on a numerical scale

  Ranking ↔️ Orders samples according to a particular attribute
• What are the primary objectives of sensory testing?

  Product development, quality control, marketing, consumer understanding
• Different sensory testing methods are used to evaluate specific characteristics of food
• What is a disadvantage of the Triangle Test in sensory evaluation?

  Requires a large panel
• Steps involved in conducting sensory testing

  1️⃣ Prepare the testing environment

  2️⃣ Design the testing protocol

  3️⃣ Distribute samples to panelists

  4️⃣ Record sensory assessments

  5️⃣ Analyze the data
• What is sensory evaluation used to measure and analyze?

  Human perception of food
• Objectivity in sensory evaluation is achieved by minimizing personal biases
• Consistency in sensory evaluation ensures reproducible outcomes by conducting evaluations under controlled conditions.
• Match the sensory evaluation method with its description:

  Triangle Test ↔️ Identifies which of three samples is different

  Paired Comparison ↔️ Determines which of two samples is stronger

  Hedonic Scale ↔️ Measures preference on a numerical scale

  Ranking ↔️ Orders samples by a particular attribute
• What are the objectives of sensory testing?

  Product development, quality control, marketing, consumer understanding
• The objective of product development in sensory testing is to improve and refine new and existing food products
• Quality control in sensory testing ensures consistency in food quality and compliance with set standards.
• Why is marketing one of the objectives of sensory testing?

  To understand consumer preferences
• Steps involved in conducting sensory testing

  1️⃣ Planning

  2️⃣ Preparation

  3️⃣ Evaluation

  4️⃣ Analysis

  5️⃣ Reporting
• What is compiled from evaluation forms during the analysis phase of sensory testing?

  Data
• Statistical methods are used in sensory testing to analyze the results
• Summarizing findings is a key part of the reporting phase in sensory testing.
• Match the statistical method with its purpose in sensory testing:

  Descriptive Statistics ↔️ Describe overall sensory attributes

  ANOVA ↔️ Compare multiple samples

  Chi-Square Test ↔️ Evaluate preference trends
• What statistical method is used to compare the sweetness ratings of two apple juice samples in sensory testing?

  ANOVA
• Understanding flavor profiles in menu planning ensures balanced meals that appeal to dietary preferences
• Paired comparison tests are used in quality control to monitor product consistency.
