Technical Document

Citric Acid Anhydrous Citric acid anhydrous is a naturally occurring organic acid found in citrus fruits, serving as a versatile food additive for pH adjustment and flavor enhancement. In the food industry, it acts as an acidity regulator to improve taste and texture in beverages, candies, and canned goods, while also functioning as a preservative to extend shelf life by inhibiting microbial growth. It stabilizes emulsions in dairy products and ice creams, prevents discoloration in fruits, and enhances mineral absorption in fortified foods.
