[ Usage ]:
Citric acid can be widely used in the food industries, such
as beverage,fermentation wine, jelly, canned fruits and jam,
as sour agent, enhance agent, buffer agent, antioxidant, chelation
agent. In medical industry, they can be used as material to
make syrup citrate, ferroammonium citrate and sodium citrate.
In chemical industry, they can be used as buffer agent, catalytic
agent , activating agent, purging agent, adsorbent, styler
and detergent.In addition, citric acid have its special uses
in Atomic Energy industry to purge and clean the radio matter
in the atomic reaction equipment from pollution.
