Relationship / difference between sodium citrate Anhydrous and sodium citrate dihydrate:
The only difference is there are 2 crystal water molecule in sodium citrate dihydrate, there is almost no difference in chemical features and applications.
1), Food industry as acidity modifier;
2), Detergent industry as water softener and auxiliary;
4), Chemical industry and etc.
1), Big solubility in water, alcohol and ether;
2), 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;
3), pH buffering ability;
4), Low toxic.
Function and application in food industry:
1), As color fixative for fresh vegetables and fruits ( 1% CAM + 1~2% sodium chloride solution);
2), As pH buffering agent and modifiers in various mass production food;
3), As antioxidant in the mass processing of many food;
4), As modifier when combined with sodium bicarbonate in wheaten food;
5), As flavor and smell-remover in salted food and cans;
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.
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).
