Free CFC Flavor Chemistry & Sensory Science Questions and Answers

Question 1

What is the primary component responsible for the taste of a substance?

Accepted Answer

Organic acids

Answer

Organic acids are a primary component responsible for the taste of a substance, specifically contributing to the sour taste. These compounds, such as citric acid in lemons or lactic acid in yogurt, interact with taste receptors on the tongue to signal sourness. Along with sweet, salty, bitter, and umami, sourness is one of the five basic tastes detected by the human palate.

Question 2

What is the difference between flavor and taste?

Accepted Answer

Flavor is the combined experience of taste and smell

Answer

Flavor is the combined experience of taste and smell, making it a much more complex sensory perception than taste alone. While taste receptors on the tongue detect sweet, sour, salty, bitter, and umami, the olfactory receptors in the nose detect volatile compounds that contribute to aroma. These two senses work together to create the rich and nuanced experience we perceive as flavor.

Question 3

What role does the olfactory system play in flavor perception?

Accepted Answer

It allows the brain to interpret taste combined with smell

Answer

Flavor is a complex sensation that extends beyond the basic tastes detected by the tongue. The olfactory system, responsible for our sense of smell, detects volatile aroma compounds that travel to the brain. When these aroma signals combine with taste signals, the brain integrates them to create the comprehensive perception we call flavor.

Question 4

Which factor can influence the perception of flavor in foods?

Accepted Answer

Temperature, texture, and aroma

Answer

Flavor perception is a multi-sensory experience influenced by various factors beyond just chemical composition. Temperature affects the volatility of aroma compounds and the sensitivity of taste receptors, while texture contributes to mouthfeel and the release of flavor. Aroma, detected by the olfactory system, is a primary component that combines with taste to create the overall flavor profile.

Question 5

What does the term 'mouthfeel' refer to in sensory analysis?

Accepted Answer

The tactile sensations experienced during consumption

Answer

Mouthfeel refers to the physical and textural sensations perceived by the tactile receptors in the mouth during consumption. These sensations include attributes like creaminess, chewiness, crispiness, viscosity, and astringency, which are distinct from taste and aroma. Mouthfeel significantly contributes to the overall enjoyment and perception of a food's quality and flavor.
