CITRIC ACID
GENERAL PRODUCT INFORMATION
Citric Acid anhydrous appears as an odorless white crystalline granule with a strong acidic taste. It is very soluble in water, freely soluble in alcohol and slightly soluble in ether.
Citric Acid is a constituent of fruit and soft drinks and other food products. Uses include flavor enhancement, bacterial inhabitant, pH adjustment, and as an anti-oxidant.
APacs Citric Acid is available in granular and fine granular particle size. Grades are available meeting the specifications of the Food Chemical Codex (FCC) and the United States Pharmacopoeia (USP).
APac's Citric acid is available Kosher certified.

Ammoniated citric acid is used to clean metal oxides from the water side of steam boilers with a two-step single-fill operation the resulting surface is clean and passivated. The cleaning solution can easily and safely be disposed of by incineration or liming.
Citric acid is used in liqued hard surface (floor). Citrate acts as a scale-dissolver, buffer and as an anti-redeposition agent.
Citric acid is added to hair care formulations to adjust the pH, act as a buffer and chelate metal ions to prevent discoloration and decomposition the presence of the citric ion stabilizes the formulation.
Citric acid is utilized in nuclear reactors to remove mill scale from welding operations. HC1 cannot be used due to the possibility of chloride stress fracturing of the stainless steel.
Citric acid is used in oil well acidizing to prevent the formation of insoluble gels of iron hydroxide.
Wells are typically injected with HC1, oxidation reactions can occur which cause formation of insoluble iron hydroxide gels. These gels interfere with pumping hydroxide gels. These gels interfere with pumping operations. Citric acid is added to the well to chelate the iron thus preventing the gel formation.
Sodium citrate is used in radiator cleaning formulations to chelated metal from the metal oxide scales and to maintain the pH.
Ship Bilge and Reverse Osmosis Cleaning
Citric acid is added to the pulp slurry prior to bleaching to control paper staining by sequestering metal ions.
In the animal feed industry, the primary use of citric acid is in pet food, where it is the flavor enhancer of choice. Fumaric acid is also used in this application.
Citric acid is widely used as a flavoring and stabilizing agent in pharmaceutical preparations. It is used in liquid preparations to enhance fruit flavors and to impart a desirable tart taste that helps mask medicinal flavors.
Citric acid help maintain stability of the active ingredients by buffering aqueous solutions, sequestering trace metals, and assisting in the dispersion of suspensions.
Citric acid is used as a chelating agent to control the deposition rate of metals in both electroplating and electroless plating operations. It is also used to buffer the pH of the plating bath.
In textile finishing, citric acid is used to adjust pH, as a buffer and as a chelating agent in dye operations and in durable-press finishes using glyoxal resins. In this application citric acid is easier and sager to work with than acetic acid.
Citric acid lowers the pH to reduce heat processing, chelates trace metals to prevent enzymatic oxidation and color degradation, and enhances the flavor.
Citric acid is utilized in the confection industry. Citrates control sugar inversion, optimize gel-setting characteristics, provides tartness and enhance flavor.
Sodium citrate is used in dairy and non-dairy creamers to stabilize the casein. This prevents feathering of the creamers when added to hot beverages.
Citric acid in the from of calcium citrate is used as a dietary calcium supplement. Studies have shown that calcium citrate is more bio-available than calcium carbonate.
Citric acid is used in dry powder beverages for flavor and pH control.
In artificially sweetened beverages citric acid add the bulk and mouth feel normally obtained from the sucrose.
Jello Brand Gelatin is another example of a food product which uses Fumaric acid. The low solubility rate is overcome by solubilizing the gelatin in boiling water.
Citric acid used in jams and jellies to provide tartness and to control the product pH for optimum gelation.
Examples of chelation in the canning industry
The lower set of canned goods demonstrates how citric acid as a chelating agent helps preserve the natural color and prevent discoloration in canned mushrooms, kidney beans and canned corn. The upper set of cans show the same products without citric acid.
Fruit and Vegetable Processing
Citric acid is used to inhibit enzymatic and trace metal-catalyzed oxidation reactions which can cause color and flavor deterioration it is often used with ascorbic acid for this purpose. The stability of frozen foods is optimized by the presence of citric acid.
Fumaric Acid is used in pudding and pie fillings to provide pH control. The non-hygroscopic nature of Fumaric acid lends itself to the less expensive packaging of these product.
Sodium Citrate is used in the process cheese industry. Sodium citrate functions as an emulsifying salt to stabilize the water and oil phases of the cheese and improves body and texture.
Citric acid is used in the seafood industry to prevent discoloration and the development of off-odors and flavors by chelating trace metals which catalyze these reactions.
Citric acid can be used in conjunction with ascorbic acid as a dip, glaze or used directly in solutions form.
