Study Notes
Sensory Evaluation
- Sensory evaluation is a scientific discipline used to evoke, measure, analyze, and interpret consumer reactions to food and other materials.
- Sensory evaluation minimizes bias from brand identity and other information influences on consumer perception.
- It aims to understand consumer preference and perception of the sensory characteristics of food and drink products.
- Sensory analysis is important for food manufacturers and retailers.
- Without appropriate sensory analysis, there is a high risk of product failure.
- Sensory evaluation is multidisciplinary; it uses principles from psychology, physiology, chemistry, and statistics.
- Instruments lack the sensitivity of human sensory systems.
- Human sensory data provides better models for consumer perception and reactions to food products.
Sensory Evaluation: Applications and Importance
- Quality Control and Assurance: It is used to establish quality standards and ensure ongoing product consistency.
- Product Development, Reformulation, and Optimization: It helps in development of new products, improving existing ones, and optimizing processes.
- Consumer Science: Understanding consumer behavior and preferences through sensory testing is crucial in marketing and developing successful products.
- Setting of Standards: It determines quality criteria and references for classifying, grading, and pricing raw materials, ingredients, and finished products.
- Marketing, Market Research, and Sales: Sensory evaluation helps evaluate products against the competition and determines consumer acceptability.
- Raw Materials and Ingredients: It helps select the most suitable suppliers and samples for production, and it helps determine shelf life.
- Intermediate Products and Packaging: Sensory evaluation is used to test the quality of intermediate products and determine the best packaging for the final product.
Misuse of Sensory Evaluation
- Use of general scoring systems, which can be vague and subjective.
- Using hedonic scales to evaluate sensory quality attributes, which can be misleading and inaccurate.
- Using inappropriate panelists for the evaluation, which can lead to biased or inaccurate results.
- Improper techniques can lead to flawed interpretations and unreliable data.
- Correlation between sensory data and objective data may be invalid if not performed correctly.
Key Questions Answered by Sensory Evaluation
- How does a product compare to competing products?
- Are reformulations improving a product?
- Is a product of consistent quality?
###Â Objective vs Subjective Evaluation
- Subjective evaluation is not synonymous with sensory evaluation.
- Sensory judgments are based on objective facts, such as the intensity response to a stimulus, the chemical, physical, and biological properties of a product, and the identifying features of a product that affect consumer acceptance.
- Subjective evaluation is appropriate for affective or hedonic testing.
The Sensory Analyst
- A sensory analyst objectively measures sensory differences or classifies product quality using a well-defined scale.
- They use their senses by applying exact methods.
- They receive specialized training and participate in periodic selection tests.
- They work in a panel where test results are statistically analyzed.
- The sensory analyst can be viewed as an objective instrument.
History of Sensory Evaluation
- Began as a field of study after World War II at the Chicago Quartermaster Food and Container Institute.
- Moved to US Army Soldiers System Center in Natick, Maryland in 1966.
- 1976 marks a historic stage for the field of sensory evaluation; it was elevated to the realm of science.
- Simple sensory tests were used by humans in the past when they relied on senses and experiences to select products.
ISO Definition of Quality and the Role of Sensory Evaluation
- Quality is defined as the totality of features and characteristics of a product or service that bear on its ability to satisfy stated or implied needs.
- Sensory evaluation provides a comprehensive understanding of sensory characteristics, product usage, and consumer acceptance.
- This information is used in both research and development (R&D) and marketing.
