Citric acid is produced from the rinds of citrus fruits via fermentation and the powdered form by dehydration. Because citric acid powder lends a tangy flavor to foods and beverages, it is commonly referred to in culinary circles as sour salt. Aside from enhancing the flavor of sourdough bread, citric acid is also used in canning, pickling and to make sausage.
Citric acid powder is also useful elsewhere around the house. In addition to acting as an emulsifier and preservative in your natural cosmetic recipes, it is also used in scrubbing powders and in homemade laundry soap and dishwasher powders.
