Application:

For the food industry
Because citric acid has a mild and sour acidity, it is commonly used in the manufacture of various beverages, sodas, wines, candies, snacks, biscuits, canned juices, dairy products and the like. In the market of all organic acids, citric acid market share of more than 70%, flavoring agents, can also be used as antioxidants in edible oils. At the same time improve the sensory traits of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus substances in the body. Anhydrous citric acid is used in large quantities in solid beverages Salts of citric acid such as calcium citrate and ferric citrate are fortifiers that require the addition of calcium and iron ions in certain foods.
Used in the chemical and textile industries
Citric acid can be used as a chemical analysis reagent for chemical analysis, as an experimental reagent, a chromatographic reagent and a biochemical reagent; as a complexing agent and a masking agent; for preparing a buffer solution. The use of citric acid or citrate as a builder can improve the performance of the washing product, can quickly precipitate metal ions, prevent the re-attachment of contaminants on the fabric, maintain the necessary alkalinity for washing, and disperse and suspend the dirt and ash; Improves the performance of surfactants, is an excellent chelating agent; can be used as an acid-resistant reagent for testing architectural ceramic tiles.
For environmental protection
Citric acid-sodium citrate buffer is used for flue gas desulfurization.
For cosmetics
Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of keratin. It is often used in lotion, cream, shampoo, whitening products, anti-aging products, acne products. The renewal of keratin helps the exfoliation of melanin in the skin, the shrinkage of pores, the dissolution of blackheads, and the like.

Feature:

Citric acid is a naturally occurring organic acid that is found in a variety of fruits, including lemons, limes, oranges and certain berries. we provides Citric acid Monohydrate and Anhydrous in markting.

Citric acid plays an essential role in the metabolism of all living things. It is a relatively weak acid and widely used throughout the food and beverage industry for a variety of purposes as an acidity regulator, preservative, flavor enhancer…etc. It is often used in the production of soda, candy, jams, and jellies, as well as processed foods like frozen and canned fruits and vegetables. Additionally, citric acid is used as a preservative to help extend the shelf life of products by inhibiting the growth of bacteria and other microorganisms.

Not only in food industry, Citric acid is also used as an antioxidant, plasticizer and detergent in the chemical industry, cosmetics industry and washing industry.

Citric acid is a very essential food additive (used mainly as an acidity regulator), obtained from processing corn into corn sugars into Citric acid.

Storage:

stored for 24 months from the date of manufacture in the un-opened original container. A relative humidity of 50% and a temperature range of 10-35ºC are the most suitable conditions for storage to prevent Citric Acid from crystallization.
