Lactic Acid Liquid (80%) has a wide range of uses in the food industry. It is a high-quality acidulant with a mild, long-lasting sourness that imparts a unique flavor to foods. It can be used in the production of beverages, yogurt, jams, candies, baked goods, and more. Adding an appropriate amount of lactic acid to beverages can adjust the taste and enhance the refreshing effect. For example, in carbonated beverages, lactic acid works synergistically with carbon dioxide to enhance the drink's refreshing effect. During the yogurt fermentation process, lactic acid is not only a fermentation product but also helps regulate the yogurt's acidity. In some topical creams and gels, lactic acid can also adjust the pH of the product.
