What makes sour sweets sour?
The sweet industry sells over 5 million pounds every year in the U.S alone and a large number of sweet lovers are drawn to the super-sour, super-sweet, super-sting taste sensation that is derived from sour sweets.
The sourness in sour sweets range from a sour-sweet-taste in Sour Patch Kids to the stronger sourness in Toxic Waste. But what makes sour sweets sour? Why are they infamous for their mouth-puckering taste?

The acids they contain
The degree of sourness in any sour sweet boils down to the acid used to make it. Each of the acid used gives a distinct tart flavour that is craved by sour sweet lovers. Here are four acids that can be found in sour sweets.
- Malic Acid
Malic acid is a natural sour compound found in green apples and cherries. This organic super sour acid is responsible for the extreme flavour and intensity of sour sweets like the notorious Warhead.
- Fumaric Acid
This acid is the strongest and most sour-tasting acid of the organic acids. Because it doesn’t dissolve easily, it is used to create a long-lasting sour flavour.
- Citric Acid
This acid comes from lemons, grapefruits and other citric fruits. It is one of the most common acids in sour sweets and it provides the tart flavour that makes sour candy so great. Toxic Waste is loaded with citric acid.
- Tartaric Acid
This acid is more astringent than citric and malic acid. They occur in many fruits like grapes, bananas, tamarinds and citrus. Sour Patch Kids contains tartaric acid and citric acid, full of protons which our tongues register as sour.
