Ürün Açıklaması

Citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystalline water, odorless, has a strong sour taste, easily soluble in water. Its calcium salts are easier to dissolve in cold water than in hot water, and this property is often used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, makeup industry, etc.
 

For use in the food industry

Because citric acid has a mild and refreshing sour taste, it is commonly used in the manufacture of various beverages, soft drinks, wine, candy, snacks, biscuits, canned juices, dairy products and other foods. In all organic acid markets, citric acid has a market share of more than 70%, and so far there is no sour agent that can replace citric acid. Monomolecular crystalline water citric acid is mainly used as an acidic flavoring agent for refreshing drinks, juices, jams, fruit sugars and canned food, etc., and canned foods, and can also be used as an antioxidant in edible oils. At the same time, it improves the sensory properties of food, enhances appetite and promotes the digestion and absorption of calcium and phosphorus substances in the body. Citric acid anhydrous is used in large quantities in solid beverages. Citric acid salts such as calcium citrate and iron citrate are fortified agents that require the addition of calcium and iron ions in some foods. Citric acid esters such as triethyl citrate can be used as non-toxic plasticizers, plastic films for food packaging, and are acidulants and preservatives in the beverage and food industries.

 

For use in the chemical and textile industries

Citric acid can be used as a reagent for chemical analysis in chemical technology, as a laboratory reagent, a chromatographic analysis reagent and a biochemical reagent; Used as a complexing agent, masking agent; Used to prepare buffer solutions. The use of citric acid or citrate as a builder can improve the performance of washing products, can quickly precipitate metal ions, prevent contaminants from reatdhesing to the fabric, and maintain the alkaline nature necessary for washing; Disperse and suspend dirt and ash; Improve the performance of surfactants, is an excellent chelating agent; It can be used as a reagent to test the acid resistance of architectural ceramic tiles.

Formaldehyde pollution of clothing is already a very sensitive problem, citric acid and modified citric acid can be made into a formaldehyde-free anti-wrinkle finishing agent, used for pure cotton fabric wrinkle-proof finishing. Not only is the anti-wrinkle effect good, but also the cost is low.
 

 

For environmental protection

Citric acid-sodium citrate buffer is used for flue gas desulfurization. China is rich in coal resources and is a major part of the energy source, but there has been a lack of effective flue gas desulfurization processes, resulting in serious atmospheric SO2 pollution. At present, China's ANNUAL SO2 emissions have reached nearly 40 million tons, and it is imperative to study an effective desulfurization process. Citric acid-sodium citrate buffer solution is a desulfurization absorber with great development value due to its low vapor pressure, non-toxicity, stable chemical properties and high absorption rate of SO2
 

 

Used in cosmetics

Citric acid belongs to a kind of fruit acid, the main role is to accelerate the renewal of keratin, commonly used in lotions, creams, shampoos, whitening products, anti-aging products, acne products and so on. The renewal of keratin contributes to the peeling of melanin in the skin, the tightening of pores, the dissolution of blackheads, etc. For example, Bioquan Vitae Soothing Cleansing Mousse makes the skin soft and comfortable, and the complexion is fresh and pure.
 

 

For sterilization

The combined action of citric acid with 80 °C temperature has a good effect of killing bacterial spores, and can effectively kill contaminated bacterial spores in the pipeline of hemodialysis machines. Lemons, which enjoy the reputation of "the king of Western food", have a strong bactericidal effect, which is very good for food hygiene, coupled with the fragrant smell of lemons, people have always liked to use it to make cold dishes, which is not only delicious and refreshing, but also enhances appetite.
 

 

For medicinal purposes

Calcium ions must be involved in the formation of prothrombin activators and later in the coagulation process. Citric acid ions and calcium ions can form a soluble complex that is difficult to dissociate, thereby reducing the concentration of calcium ions in the blood and hindering blood coagulation. The product is used as an in vitro anticoagulant during blood transfusion or laboratory blood sample anticoagulation.
