Study Notes
Sensory Analysis
- A scientific discipline used to evoke, measure, analyze, and interpret reactions to the characteristics of food as they are perceived by the senses of sight, smell, taste, touch, and hearing.
- It's a central tool in the decision-making process for food quality and positioning.
- The current challenges include food restriction, population growth, and climate change.
Decision-Making Process
- It's a mixture of sensorial, conscious, rational, and emotional factors.
- The decision process has shifted from pure instinct to a mix of rational and emotional decision-making.
- Emotion initially served as an evolutionary tool.
- The orbitofrontal cortex (OFC) is involved in decision-making, integrating sensory, emotional, and cognitive information.
Gut Instinct
- The Enteric Nervous System (ENS) is the "second brain" and is responsible for gut feelings.
Sensory Input
- Food characteristics are perceived through appearance, flavor, aroma, texture, and sound.
- Flavor is a complex combination of taste, aroma, and trigeminal sensations (mouthfeel).
- There are five basic tastes: bitterness, saltiness, sourness, sweetness, and umami.
- New tastes include fat and starchy.
- The human senses include sight, touch, hearing, smell, taste, and gut feeling, but do not include extrasensory perception (ESP).
Sensory Perception
- Perception is influenced by factors such as the color of the cup, cutlery weight, and cultural factors.
- The halo effect occurs when one attribute influences the evaluation of other attributes.
- Order effect refers to the influence of previous samples on the evaluation of subsequent samples.
- Central tendency error occurs when consumers tend to use the middle sample as a reference point.
- Contrast and convergence effects occur when samples are very different or similar.
- Cultural variations influence food terminology, familiarity, and acceptance.
- Physiological factors such as adaptation, perceptual interactions, and physical condition influence perception.
Discrimination Tests
- The Munsell color system is used to differentiate color parameters: Hue, Value (lightness), and Chroma (color purity).
- Ishihara Test detects color deficiency, particularly red-green.
Texture
- Perceive texture through touch, sound, mouthfeel, and visual cues.
- The tactile oral perception includes trigeminal sensations, which are the physical and chemical sensations in the mouth.
- Texture can change during storage, influenced by factors like temperature and moisture.
Odor Perception
- Odor is perceived through the olfactory system, which detects odor molecules in the nasal cavity.
- The orthonasal pathway involves smelling through the nose, while the retronasal pathway involves smelling through the mouth.
- Aroma refers to the odor perceived through the retronasal pathway.
Gustatory Sense
- Taste is perceived through the gustatory system, which detects dissolved molecules on the taste buds.
- Taste buds send signals to the brain, resulting in taste perception.
- Flavor is a combination of taste, aroma, and trigeminal sensations.
Sensory Bases
- Psychological factors can influence sensory perception.
- Distraction errors can occur due to stimuli outside the test environment.
- Habituation errors can occur due to repeated evaluation of similar samples.
- Stimulus-logical errors occur when judgments are based on irrelevant information.
