The Science of Sour

Why is sour candy so addictive


Sour candy is the best. It's sweet, sour, and offers a lot of flavor all at once. But why do we love it so much? When you bite into a sour piece of candy, your taste buds are engaged by both sweetness and acidity. The intensity of these two flavors combined creates an addictive sensation that makes us want more sour candy—and more and more until our mouths feel like they're covered in lemon juice! But don't worry: This feeling isn't permanent (or even dangerous). Yes, eating too much sour candy can make your mouth pucker up like you just took a swig of vinegar, but this sensation will go away once the sugar wears off and your saliva neutralizes it again.

Sour candy is addictive because it engages the brain's reward system.

When you eat sour candy, your brain releases dopamine, a neurotransmitter that makes you feel good.

Dopamine is a chemical in the brain that stimulates motivation and reward-related behavior. It's released by neurons in the brain's ventral tegmental area (VTA) and substantia nigra pars compacta (SNc), which are part of the basal ganglia circuitry responsible for movement control, learning and memory formation. These neurons receive signals from other parts of your body that control things like hunger and thirst—so when these neurons sense either one of those signals, they trigger an automatic response to get more food or water by releasing dopamine into your bloodstream where it travels throughout your body through synapses and binds with receptors on cells throughout various areas including those associated with reward processing like the nucleus accumbens and prefrontal cortex regions.

This process happens every time you eat something tasty—but what about sour candy? How does this stimulate our brains just as much as sweet things do? The answer lies in how different these two types of taste buds are.

Taste buds are also responsible for our love of sour candies.

Taste buds are also responsible for our love of sour candies. The human tongue has five basic tastes: salty, sweet, bitter, sour and umami (savory). Sour candy offers two at once—sweetness from sugar and acidity from citric acid or tartaric acid—which makes it even more appealing to taste buds than other candies that only have one type of flavor.

Sweet and sour candies are popular because they offer a lot of flavor at once.

There are a few reasons why sour candy is so popular, but one of them is the fact that it gives you a lot of flavor at once. For example, if you eat a lemon lollipop, not only will your mouth experience the sourness of lemons but also the sweet taste from sugar and artificial flavoring. This combination creates an entirely new flavor experience for your brain to process. This can be especially appealing to children who have developed some tastes for flavor combinations (e.g., chocolate with peanut butter).

Sour candies also tend to be more affordable than other types of candy because there’s less sugar involved in their production process than there would be otherwise

Citric acid gives sour candy more flavor.

Citric acid is a natural preservative, which means it helps keep food fresh. It's also widely used in sour candy because of its unique ability to add flavor to food without changing the texture or appearance.

Citric acid is found naturally in many fruits and vegetables, including oranges, lemons and limes; as well as tropical fruits like pineapple and mangoes. Citric acid can also be made synthetically from glucose by fermentation with bacteria or yeasts (byproducts of alcohol production).

Sour candy has the right balance of sweet and sour flavors that makes it irresistible to eat.

Sour candy is an irresistible treat. It has the right balance of sweet and sour flavors that makes it hard not to crave more and more.

When you bite into a piece of sour candy, your taste buds will be immediately hit with a burst of sweet flavor. But then they quickly get a kick from the sour flavor, creating a contrast between the two which makes them want to keep eating it. The combination is really satisfying!


We hope that we've helped you understand why sour candy is so addictive. Whether you're a fan of sour candy or not, knowing why it tastes so good can be interesting. In addition, this research also gives insights into how our brains work and why some foods are so popular even though they might not be the healthiest choice.
