Study Notes
- Sensory analysis is a scientific method used to evaluate the organoleptic qualities of foods and materials.
- Organoleptic quality includes sensory characteristics perceived through the senses of sight, smell, taste, touch, and hearing.
- Sensory evaluation involves evoking, measuring, analyzing, and interpreting reactions to the characteristics of foods and materials.
- Sensory analysis uses the terms odor and aroma interchangeably, but with different meanings: odor is the release of volatile substances perceived directly by the nose, while aroma is perceived through the retro-nasal pathway during degustation.
- Taste or flavor is the complex set of olfactory and gustatory sensations perceived during consumption.
- There are several tastes or flavor profiles, including sour, bitter, salty, and sweet.
- Sensory analysis is used for research and development, quality control, marketing, and consumer preference research.
- The physiology of perception involves the transformation of stimuli into nervous influxes, which are then interpreted by the brain.
- The sensory response is influenced by both physiological and psychological factors.
- Physiological factors include ageusia (loss of taste), persistence (duration of the sensation), and sensitivity to different stimuli.
- Psychological factors include prior expectations, nearby influences, and the order of presentation of samples.
