E334, or citric acid, is a food additive widely used in the food industry as a preservative, acidity regulator, and antioxidant.
Citric acid itself contains no carbohydrates. However, during metabolism, citric acid can be converted into carbohydrates, so it should not be consumed in excess.
When used properly in moderate amounts, E334 should not take one out of ketosis.
Citric acid E334 is often used in the production of beverages, confections, marinades, juices, jellies, and as an additive in meat products.
Citric acid is considered safe for consumption in small amounts. However, excessive intake may lead to negative consequences such as gastrointestinal irritation.
