  What is citric acid? According to research online data, citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystal water, odorless, has a strong sour taste, easy Dissolved in water. Its calcium salt is easier to dissolve in cold water than in hot water. This property is often used to identify and separate citric acid. So, what are the uses of citric acid? We know that citric acid should be used in many occasions, let's talk about the uses of citric acid.

  What is citric acid? What are the uses of citric acid?

  Citric acid is the largest acid among organic acids. Due to its physical properties, chemical properties, and derivative properties, it is the most important organic acid widely used in food, medicine, and daily chemical industries. Let's analyze the use of citric acid in detail.

  1. Used 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, wines, candies, snacks, biscuits, canned juices, dairy products and other foods. In all organic acid markets, citric acid has a market share of more than 70%. So far there is no sour agent that can replace citric acid. One molecule of crystalline water, citric acid, is mainly used as an acid flavoring agent for refreshing drinks, fruit juices, jams, fruit candies and canned food, and can also be used as an antioxidant for 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 in the body.

  2. Used in the chemical, pharmaceutical and textile industries

  In chemical technology, citric acid can be used as a reagent for chemical analysis, as an experimental reagent, chromatographic analysis reagent and biochemical reagent; as a complexing agent and masking agent; and as a buffer solution. Using citric acid or citrate as a builder can improve the performance of washing products, can quickly precipitate metal ions, prevent pollutants from reattaching to the fabric, and maintain the necessary alkalinity for washing; disperse and suspend dirt and ash; It is an excellent chelating agent to improve the performance of surfactants; it can be used as a reagent for testing the acid resistance of architectural ceramic tiles.

  Citric acid-sodium citrate buffer is used for flue gas desulfurization. my country is rich in coal resources and constitutes the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, which has caused serious atmospheric SO2 pollution. At present, my country's annual SO2 emissions have reached nearly 40 million tons. Research on effective desulfurization processes is indeed a top priority. Citric acid-sodium citrate buffer solution is a desulfurization absorbent with great development value due to its low vapor pressure, non-toxicity, stable chemical properties, and high absorption rate of SO2.

  4. Used in livestock production

  Adding citric acid to piglet feed can wean early, increase feed utilization rate by 5% to 10%, and increase sow litter size. Adding 1% to 2% citric acid in the diet of growing and finishing pigs can increase daily gain, reduce feed-to-meat ratio, increase protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics. Rare earth citrate is a new type of high-efficiency feed additive, suitable for pigs, chickens, fish, shrimps, cattle, sheep, rabbits, silkworms and other animals. It can promote animal growth, improve product quality, increase disease resistance and survival rate. Improve the feed conversion rate and shorten the feeding cycle. At this time we have to admit that the uses of citric acid are very wide.

  5. Used in cosmetics

  Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of keratin. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. The renewal of keratin helps to peel off the melanin of the skin, shrink pores, and dissolve blackheads. For example, Biotherm Living Spring Soothing Cleansing Mousse makes the skin soft and comfortable, and the complexion is fresh and pure.

  6. Used for sterilization

  The combined effect of citric acid and 80°C temperature has a good effect of killing bacterial spores, and can effectively kill bacterial spores contaminated in the hemodialysis machine pipeline. Lemon, known as the "King of Western Food", has a strong bactericidal effect and is good for food hygiene. Coupled with the fragrance of lemon, people have always liked to use it to make cold dishes, which are not only delicious and refreshing, but also increase appetite.

  7. Used in medicine

  In the formation of prothrombin activator and the subsequent clotting process, calcium must be involved. Citrate 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. This product is used as an in vitro anticoagulant in blood transfusion or laboratory blood sample anticoagulation.
