Description
Citric acid is an important organic acid, also known as citric acid, colorless crystals, often contains a molecular crystalline water, odorless, and has a strong sour taste, which is easy to dissolve in water. Its calcium is easily dissolved in cold water than hot water. This nature is often used to identify and separate citric acid. Control the appropriate temperature when crystallization can obtain water -free citric acid. In the industry, the food industry, and the makeup industry, there are many uses.
The main uses are:
Used for the food industry
Because citric acid has a mild and refreshing sour taste, it is generally used in various beverages, soda, wine, candy, snacks, biscuits, canned fruit juice, dairy and other foods. In all organic acid markets, the citric acid market share is more than 70%, and there is no acidic agent that can replace citric acid. Penal crystalline water citric acid is mainly used as acidic condiments such as cool beverages, juice, jams, fruit sugar, and cans. It can also be used as antioxidants for edible oil. At the same time, improve the sensory characteristics of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus in the body. Aquatic citric acid is used in solid drinks. Saltic acids such as calcium citrate and iron citrate are enhanced agents that need to add calcium ions and iron ions in certain foods. The ester of citric acid such as citric acid can be used as non -toxic plasticizers. Plastic film is used to make food packaging. It is a acid -flavored agent and preservatives in the beverage and food industry.
Used for chemical and textiles
Citric acid can be used as a chemical analysis reagent in chemical technology, used as experimental reagents, chromatography analysis reagents and biochemical reagents; used as complexing agents, masking agents; to prepare buffer solutions. The use of citric acid or citric acid as a citrate can improve the performance of washing products, which can quickly precipitate metal ions to prevent pollutants from re -attached to the fabric to keep the necessary alkaline of washing; Improving the performance of the surfactant is an excellent october; it can be used as a reagent for testing the acid resistance of building ceramic tiles.
The formaldehyde pollution of clothing is already a very sensitive problem. Citric acid and modified citric acid can be made into a non -wrinkle non -wrinkle of cotton fabric. Not only is the anti -wrinkle effect, but the cost is low.
For environmental protection
Sodium citric acid-sodium citrate buffer is used for flue gas desulfurization. The rich coal resources in China are the main part of energy. However, the lack of effective flue gas desulfurization technology has always been lacking, resulting in serious pollution of atmospheric SO2. At present, China 's SO2 has been in place for nearly 40 million tons. It is a top priority to study an effective desulfurization process. Sodium citric acid-sodium citrate buffer solution is a densely developed desulfurization absorbent due to its low steam pressure, non-toxic, stable chemical properties, and high absorption rate of SO2.
Used for poultry production
Adding citric acid to piglet feed can wean it early, increase the feed utilization rate by 5%to 10%, and increase the amount of sow production. Add 1%to 2%citric acid to the growth of fattening pig diets, which can increase daily weight gain, reduce the meat ratio, increase protein digestive, reduce the thickness of the back fat, and improve the characteristics of meat and carcass. Symphony of citric acid is a new type of high -efficiency feed additive. It is suitable for various animals such as pigs, chickens, fish, fish, shrimp, beef, sheep, rabbits, and silkworms. Increase the characteristics of feed conversion and shorten the feeding cycle.
For cosmetics
Citric acid is a type of fruit acid. The main role is to accelerate keratin update. It is often used in lotion, cream, shampoo, whitening supplies, anti -aging products, and acne supplies. The keratin renewal helps the skin of the skin in the skin, the pores are retracted, and the dissolution of blackheads. For example, Biobuan live spring Shumin cleansing Mosice makes the skin soft, comfortable, and the skin tone is fresh and pure.
Use for sterilization
The combination of citric acid and the temperature of 80 ° C has the effect of killing bacterial spores, and can effectively kill the contaminated bacterial spores in the hemodialysis machine pipeline. Lemon with the reputation of "King of Western Food" has a strong sterilization effect and is good for food hygiene. Coupled with the aroma smell of lemon, people have always liked to make cold dishes, which not only delicious and refreshing, but also enhance appetite.
For medicine
Calcium ions must be participated during the formation of coagulantic activation and subsequent coagulation. The root ions and calcium ions of citrate can form a soluble complex that is difficult to dissolve, which reduces the calcium ion concentration in the blood and blocked the blood. This product is used as an external anticoagulant when blood -transfusion or laboratory hemororbing anticoagulation.
