Usage of citric acid

Citric acid is mainly used as part of crystal water soft drinks, fruit juices, jams, canned fruit sugar and acidic flavoring agent, can be used as edible oil antioxidant. While improving the sensory properties of food, increase appetite and promote the body of calcium, phosphorus digestion and absorption of the material. Anhydrous citric acid is used extensively for solid drink. Citric acid salts such as calcium citrate and ferric citrate are certain foods you need to add calcium and iron ions enhancer. Citric acid esters such as triethyl citrate can be used for non-toxic plasticizer manufacturing plastic films for food packaging, beverage and food industries sour agents, preservatives.

Citric acid can be used in the chemical technology for chemical analysis reagent is used as laboratory reagents, chromatography reagents and biochemical reagents; used as a complexing agent, a masking agent; for the preparation of a buffer solution. Salts of citric acid or citric acid as builders, can improve the performance of cleaning products can be quickly precipitated metal ions prevent contaminants from re-adhering to the fabric, necessary to maintain an alkaline washing; so disperse and suspend the dirt and ash; improve the performance of the surfactant is an excellent chelating agent; building ceramic tiles can be used as the acid test of reagents.

Formaldehyde contamination of clothing is a very sensitive issue, citric acid and citric acid can be made of a modified formaldehyde-free wrinkle finishing agent for cotton fabrics crease-resistant finishing. Not only good wrinkle effect, and low cost.

For environmental protection

Citric acid - sodium citrate buffer for flue gas desulfurization.Chinais rich in coal resources, is the major component of the energy, however, has been the lack of effective flue gas desulfurization process, causing atmospheric SO2 pollution. At present, China SO2 emissions by nearly 40 million tons, research and effective desulfurization process, in fact, imperative. Citric acid - sodium citrate buffer solution because of its low vapor pressure, non-toxic, chemically stable, SO2 absorption rate for other reasons, is great value desulfurization absorber.

For livestock production
