Study Notes
Designing Sensory Test Rooms for Analysis
- Sensory analysis can be affected by various people-related issues such as mood, illness, hunger, and psychological errors.
- Environmental issues such as noise, temperature, lighting, and odors can impact the accuracy of sensory analysis.
- ISO standards provide guidance for designing test rooms to eliminate environmental effects.
- Test rooms should have controlled conditions, minimal distractions, and areas for preparation, testing, and discussion.
- Ideal temperature and relative humidity for test rooms are 20-22°C and 50-55% respectively.
- Test rooms should have neutral decoration, uniform lighting, and odor-free air conditioning with activated carbon filters.
- Testing booths should be designed with specific dimensions, numbered, and equipped with communication systems.
- Group work areas are essential for discussion, training, and debriefing sessions.
- A well-equipped preparation area is necessary for sample handling, storage, and washing facilities.
- Test protocol considerations include balanced randomization, coded samples, and considering the effects of sample characteristics on product evaluation.
- Sensory test methods include objective and subjective tests, such as discrimination tests and hedonic/consumer tests.
- Different test methods provide data on differences, degree of liking, and acceptability of products.
