    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.
