Uses of citric acid
2022-03-04
1. Food industry
1) Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, soft drinks, wine, candy, snacks, biscuits, canned juice, dairy products and other foods, 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) The salts of citric acid such as calcium citrate and ferric citrate are fortifiers that need to add calcium ions and iron ions in some foods.
3) Esters of citric acid, such as triethyl citrate, can be used as non-toxic plasticizers to manufacture plastic films for food packaging, as sour agents and preservatives in beverage and food industries.
2. Industrial application
1) Citric acid can be used as chemical analysis reagent, experimental reagent, chromatographic analysis reagent and biochemical reagent; used as complexing agent, masking agent; used to prepare buffer solution.
2) The use of citric acid or citrate as a builder can improve the performance of washing products, can rapidly precipitate metal ions, prevent pollutants from re-attaching to the fabric, and maintain the necessary alkalinity for washing; disperse and disperse dirt and ash. Suspension; improve the performance of surfactants, is an excellent chelating agent;
3) It can be used as a reagent for testing the acid resistance of architectural ceramic tiles.
4) Citric acid and modified citric acid can be made into a formaldehyde-free anti-wrinkle finishing agent for the anti-wrinkle finishing of pure cotton fabrics. Not only the anti-wrinkle effect is good, but also the cost is low.
5) It also has metal complexing ability, has good complexing ability to metal ions, and is used as a complexing agent and buffer in the electroplating industry.
3. Environmental protection
Citric acid-sodium citrate buffer is used for flue gas desulfurization. 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. Livestock and poultry feed
Adding citric acid to piglet feed can lead to early weaning, improve feed utilization by 5% to 10%, and increase sow litter size. Adding 1% to 2% citric acid to the diet of growing-finishing pigs can increase daily weight gain, reduce feed-to-meat ratio, improve 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, improve disease resistance and survival rate. Improve the feed conversion rate and shorten the feeding cycle.
5. Cosmetics
Citric acid is a kind of fruit acid. Its main function is to speed up keratin renewal. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. The renewal of keratin is helpful for the exfoliation of melanin in the skin, the reduction of pores, and the dissolution of blackheads.
6. Cleaning and descaling
Citric acid has the ability to disinfect, bleach and eliminate fat, it can remove limescale, wipe the surface of kitchen stoves, clean sinks, sewer pipes, glass surface cleaning, etc.
7. Sterilization
The combined action of citric acid and 80°C temperature has a good effect on killing bacterial spores, and can effectively kill bacterial spores polluted in the pipeline of hemodialysis machine.
