PRODUCT DEVT QUIZ 1

It is a scientific method used to evoke, measure, analyse and

interpret those responses to products as perceived through the senses of sight,

hearing, touch, smell and taste

• Sensory Evaluation

• Sensory Testing

• Consumer Acceptability

• All of these

These are volatile compounds which are

perceived by the odor receptors of olfactory tissues of the nasal cavity.

• Flavor

• Aroma

• Appearance

• Texture

It is perceived by a combination of senses i.e. touch, mouthfeel, sight and

hearing.

• Texture

• Aroma

• Flavor

• Appearance

It involves the perception of constituents after being dissolved in saliva, oil or water

by taste receptors in the taste buds found superficially on the tongue and other parts of the mouth or gullet.

• Taste

• Vision

• Smell

• Sound

What category in Texture is hardness and chewiness?

• mechanical

• geometric

• mouth-feel

• None of these

Human skin including the tongue, surfaces of the oral cavity and lips

encompasses numerous tactile receptors to detect sensations related to touch, e.g.

particle size.

• Somesthesis

• Kinesthesis

• Chemesthesis

• All of these

Stimuli like radio, chatting and personal obsessions in the evaluation area can

easily influence the panelists.

• Distraction Error

• Stimulus and Logical Error

• Attribute Dumping

• Expectation Error

This happens where judges evaluate similar stuff repetitively.

• Order Effect

• Acclimatization

• Halo Effect and Proximity Error

• Contrast and Convergence Effects

Certain stimuli can interact to cause suppression (existence of one ingredient

diminishes the perceived concentration of another, e.g. sourness reduces

apple flavor), potentiation (occurrence of one element surges the intensity of

another, e.g. Chinese salt accelerates the meat flavor) and synergy (intensity of a

mixture is greater than the intensity of the sum of the individual components, e.g.

sweetness and sourness impact on strawberry flavor).

• Perceptual Interactions between Stimuli

• Physical Condition

• Adaptation

• All of these

waiting room itself by making seating arrangements in rows or semi-circle.
