Louis François Citric Acid is a high-quality, food-grade acidulant derived from citrus fruits, commonly known as "sour salt." This fine, white powder is widely used in culinary applications to adjust acidity, enhance flavors, and act as a natural preservative. It is particularly effective in preventing oxidation and browning in fruits and vegetables, making it ideal for canning, preserving, and preparing jams and jellies. Additionally, citric acid serves as a leavening agent when combined with baking soda and is a key ingredient in confectionery, beverages, and marinades, providing a tangy, citrus-like flavor.
