Adipic acid CAS#124-04-9

Basic Information

Adipic acid

Adipic acid is a nonhygroscopic food acidulant with relatively low acidity and useful buffering behavior. It dissolves slowly in cold water and provides smooth tartness, flavor persistence and dry-powder handling advantages. It is used in beverages, desserts, gelatin products, baking powder and canned foods, and can help control browning or oil-rancidity effects in formulations. It is also selected where stable powdered acidification is required.
