Functional Acids
General information
In certain applications some of the standard product properties of citric acid are not adequate. Coating citric acid with suitable transparent shell materials or adding high-quality materials to citric acid lead to an exceptional range of modified citrics and a fine-tuning of the desired functionality for customer applications.
These modifications prevent undesired reactions with other ingredients as well as protection against moisture without losing its original function.
Citric acid DC is a direct compressible type of citric acid coated with a thin layer of maltodextrin.
CITROCOAT® N is comprised of citric acid as the core material, with a layer of a citrate as shell material.
CITROCOAT® EP is an agglomerated effervescent compound bringing CITROCOAT® N and sodium bicarbonate together in the exact right composition to create a highly reactive but storage stable effervescent compound.
Citric acid S40 is a very fine pulverised powder, blended with a slight amount of anti-caking agent silicon dioxide (SiO2), which displays a high ability to absorb spurs of humidity.
