Explain why fizzy candies sizzle in the mouth?

In short (click here for detailed version)

The fizzy candies crackle in the mouth due to the chemical reaction between the sodium bicarbonate and citric acid present in the candy. This reaction produces carbon dioxide, forming small bubbles that burst and crackle, providing this unique sensation.

Explain why fizzy candies sizzle in the mouth?
In detail, for those interested!

First factor: Dissolved CO2

The first factor explaining the crackling of popping candy in the mouth lies in the presence of carbon dioxide (CO2) dissolved in the composition of these candies. When the candies come into contact with saliva, the dissolved carbon dioxide is released in the form of small bubbles that burst, producing the characteristic popping effect. This phenomenon is similar to what happens when opening a bottle of soda: the sudden release of dissolved carbon dioxide leads to the formation of bubbles on the surface of the liquid. As a result, the crackling sensation felt in the mouth is due to the interaction between the dissolved carbon dioxide and saliva, which releases the gas and creates these small bubbles.

Second factor: Acid-base reaction.

When a popping candy is placed in the mouth, an acid-base reaction occurs that gives rise to the popping sensation. This reaction involves acidic and basic compounds present in the candy. Most often, the candy contains an acid such as citric acid or malic acid and sodium bicarbonate. When these two compounds come into contact with saliva, an acid-base reaction occurs.

The acid present in the candy reacts with the hydrogen ions in saliva to form water. This reaction releases carbon dioxide (CO2) in the form of gas. The CO2 is responsible for the formation of small bubbles that give the candy its popping effect. The release of this gas creates a tingling and popping sensation in the mouth, providing a unique sensory experience.

In addition to the formation of CO2, the acid-base reaction can also release other compounds that contribute to the intensity of the taste and mouthfeel. The combination of these elements creates a fun and stimulating gustatory and tactile experience for the taste buds, making popping candies a delight to enjoy.

Third factor: Energy release

When fizzy candies are consumed, a chemical reaction occurs between the candy's components and the saliva in the mouth. This chemical reaction leads to the release of energy, which manifests as crackling and tingling sensations. The release of energy is due to the transformation of the candy's chemical components into end products. This process releases heat and creates gas bubbles, which contributes to the fizzy effect felt in the mouth.

Frequently Asked Questions (FAQ)

1

What is the reason behind the crackling of popping candy in the mouth?

Fizzy candies crackle thanks to the release of carbon dioxide (CO2) when they come into contact with saliva, causing a chemical reaction.

2

How is CO2 released in fizzy candies?

CO2 is often present in fizzy candies in the form of sodium bicarbonate. When the candy dissolves in saliva, the bicarbonate reacts with acids present, releasing the CO2.

3

Why do we feel a tingling sensation when eating fizzy candies?

The tingling is due to the stimulation of pain receptors by the released carbon dioxide, causing a tickling sensation in the mouth.

4

Are fizzy candies dangerous for your health?

In general, fizzy candies do not pose a health risk. However, excessive consumption can cause digestive issues in some sensitive individuals.

5

How are fizzy candies made to achieve this effect?

Fizzing candies are made by mixing acidic ingredients and sodium bicarbonate, which react together to produce CO2 and create the fizzing effect.
