  Main application:

  1), Food industry as acidity modifier;

  2), Detergent industry as water softener and auxiliary;

  3), Cosmetics;

  4), Chemical industry and etc.

 

  Main types:

  According to the particle size, there are mainly 2 types:

  1), 10-40 mesh;

  2), 30-100 mesh.

 

  Features:

  1), Big solubility in water, alcohol and ether;

  2), Among all the sour agents, CAA’s acidity is the most accepted by human;

  3), Water softening ability, it can combine the Ca2+ and other metal ions (except for alkali metal), and for the compounds (like Calcium citrate), their solubility in cold water is higher than hot water, which is a big advantage in detergent industry;

  4), pH buffering ability;

  5), Low toxic.

 

  Function and application in food industry:

  1), As sour agent in beverages, can, candy, and etc;

  2), As sucrose conversion agent in sugar making;

  3), As color fixative for fresh vegetables and fruits ( 1% CAA + 1~2% sodium chloride solution);

  4), As pH buffering agent and modifiers in various mass production food;

  5), As antioxidant in the mass processing of many food;

  6), As modifier when combined with sodium bicarbonate in wheaten food;

  7), As flavor and smell-remover in salted food and cans;

  8), Slower the decline speed of Vc concentration in orange juice;

 

  Function in detergent industry:

  Replacing STPP to soften water with the following advantages:

  1), Environmental friendly with good bi-degradation;

  2), Better safety in dish washing and other related detergents which can enter human organs easily;

  3), Good chelating ability, not only to Ca2+, Mg2+ but also to other non-alkali metal ions, and the solubility of these chelated salts in cold water is bigger than hot water;

  4), Better solubility than STPP, Zeolite;

  5), Good pH buffering ability;

  6), Rust inhibiting ability which is good for the related equipments and pipes;

  7), Thickening agent in liquid detergent system.

 

  Important notice:

  1), Citric Acid anhydrous is easily get caked when exposed in air;

  2), Relationship / difference between Citric Acid Anhydrous and Citric Acid Monohydrate:

  The only difference is there is a crystal water molecule in CAM, there is almost no difference in chemical features and applications.

  3), We normally list 2 years as the shelf life in our COA, the real shelf life can be slightly longer than 2 years if it’s stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
