Study Notes
Sensory Evaluation and Food Product Development
- Sensory evaluation is the scientific discipline used to evoke, measure, analyze, and interpret human reactions to food and beverage characteristics, as perceived by sight, smell, taste, touch, and hearing.
- Sensory evaluation is critical for cost-effective product development, reducing uncertainty in decision-making, and serving as a valuable measuring instrument.
- Sensory evaluation often uses human observers, who can sometimes detect odorants at lower levels than instruments, though instruments cannot measure liking.
- The sensory process is a multi-step process, involving stimulus (food), sensory organ, sensation (nerve signal), brain, perception, and response. Intensity and thresholds play a role.
- Sensory evaluation considers factors such as culture, environment, health, age, material science, physical and chemical properties of foods (including temperature and deformation history), physiology, psychology, and in-mouth processes (including oral and sensory physiology).
- Sensory evaluation tests include discrimination, descriptive, and affective (acceptance/preference) testing. These tests aim to answer distinct questions about the product.
- Discrimination tests determine if products are detectably different, using tests like Paired, Duo-trio, Triangle, Ranking, and Rating Difference. Data analysis considers statistical significance.
- Descriptive tests identify and quantify perceived product characteristics, like flavor or texture, using highly trained panelists and precise wording. Quantitative descriptive analysis includes flavor and texture profiles.
- Affective tests gauge consumer liking or disliking of products through preference or acceptance tests, often involving a large number of panelists.
- Consumer tests measure acceptance and preference with various scales, including the 9-point hedonic (liking) scale and smiley scales. Other common scales include 3, 5, and 7 point scales.
- Proper test room conditions are necessary, which include minimizing distractions, using individual sensory booths, neutral colors, comfortable temperature, separation of panelists and sample preparation areas, adequate ventilation, no talking, and possibly computer terminals, and different door designs.
- Sensory evaluation is critical in product development. A scientific approach is essential, starting with defining the problem and setting hypotheses that are then tested. Product development stages include: ideation, analysis testing, sensory evaluation and benchtop/prototype creation culminating in commercialization and market testing. A multi-faceted understanding of product development, along with acceptance testing and preference testing is crucial.
