CITRIC ACID

Citric Acid is found naturally in citrus fruits, especially lemons and limes. It's what gives them their tart, sour taste. A manufactured form of citric acid is commonly used as an additive in food, cleaning agents, and nutritional supplements. Citric acid is often added to packaged food and drinks. It helps keep canned and jarred foods fresh over long periods of time. It can prevent some kinds of fresh-cut produce, like sliced apples, from turning brown. Citric acid can also help thicken foods or give them a slightly sour flavor.
