Citric Acid To Maintain Color

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. It is produced commercially through the fermentation of carbohydrate solutions, typically using the mold Aspergillus niger. This process yields a highly pure, crystalline powder.

Manufacturers add citric acid primarily to regulate acidity and enhance flavor in foods and beverages. It acts as a preservative by preventing the growth of bacteria and molds, and it helps maintain color in processed foods. It is commonly found in candies, jams, jellies, soft drinks, and canned fruits and vegetables.

In the United States, citric acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved as a food additive and is permitted for direct addition to food for human consumption. International bodies like JECFA and EFSA have evaluated citric acid and have not set a numerical acceptable daily intake (ADI), indicating it is considered safe at typical consumption levels. It is not known to cause adverse health effects when consumed in amounts typically found in food.
