Cleverpops contain the natural preservative Citric Acid which also enhances flavour.
Citric Acid is found naturally in citric fruits such as lemons, limes, grapefruit and oranges at high levels.
Citric acid is a weak organic acid. It is a natural preservative and is also used to add an acidic, or slightly sour, taste to foods and soft drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
