Application / Intended Use
Citric acid monohydrate is the standard acidulant and pH regulator for beverages, jams and confectionery, usually at 0.1-0.5% of the finished product, where it sharpens flavour and lowers pH for microbial stability. It chelates metal ions, so it is also used as an antioxidant synergist in fats and as a descaling and cleaning agent in industrial CIP systems.
