If you're into sprouting then you're already familiar with Citric Acid (anhydrous), a natural preservative typically found in citrus fruits such as lemons and limes. A white crystalline powder that acts as a natural preservative and also produces a sour taste in foods, Citric Acid is added to ice cream as an emulsifying agent. It can be used with sugar when making caramel to prevent crystallization, or can be used in recipes in place of lemon juice. Citric Acid helps to create the fizz in carbonated beverages and is used in canning to increase the acidity content in ingredients such as tomatoes.
