Citric Acid Monohydrate Specification C6H8O7 H2O

Hello Food Scientists, This is Recipanda again with a new food additive that is widely used in food and beverage manufacturing and is present in most formulas. Today we will write about monohydrate citric acid specification and how you can choose a raw material that matches the specifications.

Citric Acid Monohydrate Specification C6H8O7 H2O

Citric Acid Monohydrate Uses

Whether you use monohydrate or anhydrous citric acid, both are used as a preservative, flavouring agents, Acidity regulator and for pH adjustment.

Most manufacturers making citric acid C6H8O7 H2O from lemon because it contains a high concentration of citric water.
