According to food chemist Sara Risch, founder of food and packaging consultancy Science by Design, while the soda's formula remains the same, the plastic, aluminum, or glass packaging can impact the flavor as the liquid reacts with polymers in the packaging, she told Popular Science. Not to give you too many flashbacks to high school chemistry class, but according to Popular Science , polymers are the molecules inside the packaging that can add properties to the material they are used in.
For example, aluminum cans are lined with a polymer that can absorb small amounts of flavor and plastic bottles may transfer acetaldehyde that can alter the way a drink tastes. Glass is a more inert material than either aluminum or plastic, so it's less likely to affect the flavor of your drink.
That's why drinking out of a glass bottle may be the way to get the purest Coca-Cola flavor. It's important to note that the Food and Drug Administration FDA closely monitors food packaging to make sure that toxic or dangerous chemicals don't leach into food or drink. And for the bonus round, do you swear Coke at McDonald's boasts a superior flavor profile? Well, if you answered "yes" to one or more of the above questions, you not only have a rather refined soda palate, but you're probably curious as to why soda tastes different depending on how it's packaged.
You're thirsty for answers, and we've got 'em! First things first, when it comes to this ongoing battle: Soda makers will tell you it's the same recipe, same ingredients, and the same manufacturing process being used, no matter the packaging. But again, soda makers disagree, insisting that perception of taste is influenced by things like how cold your fizzy beverage is and whether it's poured over ice.
That's hard to swallow, though, if you're sure you can tell the difference between a can of soda and a bottle and have a strong preference.
Sara Risch , a food chemist, has inferred that you can go ahead and trust your taste buds. Companies try to squelch any reaction packaging might have on soda by lining cans with polymers. But, the polymer lining aluminum soda cans could absorb flavors.
When it comes to plastic bottles, soda drinkers might find that some of the acetaldehyde transfers over into the drink, affecting the flavor. While the FDA regulates chemical contact, even trace amounts might have an impact on flavor, explains Popular Science. This explains why soda may taste best from a glass bottle, as there aren't any reactions affecting the flavor profile.
Now, you might be wondering exactly how this specific type of the fizzy drink factors into the discussion. Recipient's Email. Your Feedback. Your Email optional. Report a Comment. Please select the reason for reporting this comment.
