Sodas Change Flavor Depending on the Packaging — See What Causes This Difference

Differences In The Taste Of Canned Or Bottled Sodas Is The Result Of The Interaction Of The Drink With The Packaging Materials, Such As Aluminum, Plastic, And Glass

Some soda fans claim that canned sodas have a different taste from the plastic bottled version. Understand below what causes these changes in flavor.

A study from All Recipes explains that the composition of sodas does not change depending on the container. Companies use the same formula, whether it is in a can, plastic bottle, or glass.

However, factors such as temperature, storage time, and product age can affect the taste. Additionally, the materials of the containers also exert influence.

The Effect Of Aluminum Cans

Aluminum cans have an internal coating made from a water-based polymer. This prevents the soda from coming into direct contact with the metal and avoids altering the flavor.

Without this coating, the liquid could corrode the can and acquire a metallic taste. Some consumers notice that canned sodas have a smoother taste, which can be attributed to the polymer.

The Impact Of Plastic Bottles

Plastic bottles contain a chemical compound called acetaldehyde. This element can be transferred to the liquid and slightly modify the flavor. Additionally, plastic is more porous than aluminum and glass, allowing carbon dioxide to escape more easily.

Since the gas is responsible for the carbonation of the drink, this loss can make the soda seem less fresh.

Glass Maintains The Original Taste Of Sodas

For those seeking a purer taste, the best choice may be a glass bottle. Unlike plastic and aluminum, glass does not release chemicals into the drink. This ensures that the soda retains its original flavor without external interference.

The difference in the taste of sodas does not come from the recipe, but rather from the interactions between the liquid and the material of the container. This explains why some consumers perceive variations in flavor depending on the type of packaging.
