What are the effects of citric acid

Citric acid is an organic acid that has important applications in many fields.So what effect does citric acid have, what effect does citric acid have, what is the extraction method of citric acid, what benefits does citric acid have to the human body? Let's take a look at it together.

Citric acid, also known as citrate, colorless crystal, often contains a molecule of crystal water, odorless, has a strong acid taste, easily soluble in water.Its calcium salt is more soluble in cold water than in hot water. This property is often used to identify and separate citric acid.Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization.

The following is a detailed analysis of the use of citric acid.

1. Used in food industry

Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various drinks, soft drinks, wines, candies, snacks, cookies, canned fruit juices, dairy products and other foods.In all the organic acid market, citric acid market share of more than 70%, so far there is no one can replace citric acid acid agent.A molecule of crystal water citric acid is mainly used as an acid flavoring agent in cooling drinks, fruit juices, jams, fruit drops and canned goods. It can also be used as an antioxidant in edible oils.At the same time, improve the sensory properties of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus substances in the body.

2. Used in chemical, pharmaceutical and textile industries

Citric acid can be used as a reagent for chemical analysis, as an experimental reagent, a chromatographic reagent and a biochemical reagent.Used as complexing agent, masking agent;Used to prepare buffer solution.The use of citric acid or citric acid salts as washing AIDS can improve the performance of washing products, can quickly precipitate metal ions, prevent the re-attachment of pollutants on the fabric, and maintain the necessary alkalinity of washing;To disperse and suspend dirt and ashes;It is an excellent chelating agent to improve the performance of surfactant.It can be used as a reagent to test the acid resistance of building ceramic tiles.

3. Citric acid - sodium citrate buffer for flue gas desulfurization

China is rich in coal resources, which constitute the main part of energy. However, there has been a lack of effective flue gas desulfurization process, resulting in serious atmospheric so2 pollution.At present, China's annual emissions of so2 have reached nearly 40 million tons, so it is urgent to study effective desulfurization technology.Citric acid - sodium citrate buffer is a valuable desulfurization absorber because of its low vapor pressure, non-toxic, stable chemical properties and high absorption rate of so2.

4. For livestock production

Adding citric acid to piglet feed can be early weaning, improve feed utilization rate by 5% ~ 10%, and increase sow litter.Adding 1% ~ 2% citric acid to the diet of growing and fattening pigs can increase daily weight gain, reduce feed to meat ratio, increase protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics.Citric acid rare earth is a new and efficient feed additive, suitable for pig, chicken, fish, shrimp, cattle, sheep, rabbit, silkworm and other animals, which can promote animal growth, improve product quality, improve disease resistance and survival rate, improve feed conversion rate and shorten feeding cycle.At this point we have to admit that citric acid is very versatile.

5. For cosmetics

Citric acid belongs to a kind of fruit acid, main action is to quicken cutin to renew, often use at latex, milk frost, shampoo, beautiful white thing, fight ageing thing, whelk thing to wait.The cutin renewal is helpful to the skin in melanin flaking, the pore close fine, the black head dissolve and so on.For example, biotherm live spring shumin cleanser mousse makes the skin soft and comfortable, and makes the complexion fresh and pure.

6. For sterilization

The combined action of citric acid and 80℃ has a good effect on killing bacterial spores, and can effectively kill the contaminated bacterial spores in the pipeline of the blood dialyzer.The lemon that enjoys "king of western food" good reputation has very strong antiseptic effect, have profit to food sanitation very much, plus the faint scent of lemon, people all along like to use its make cold dish, not only delicious and refreshing, also can increase appetite.

7. Used in medicine

Traditional Chinese medicine thinks, lemon sex is lukewarm, taste is bitter, avirulent, have the function such as quench thirst to grow jin, dispel heat to install embryo, thin sluggish, strong stomach, analgesic diuresis, adjust hemal to appear a gender, suit the mm of puffiness and fatness.Smokers should eat more lemons because they need twice as much vitamin c as non-smokers.Lemon quantity of heat is low, and have very strong contractility, because this is helpful for reducing adipose, it is good medicine reducing weight.Lemon can prevent cardiovascular arteriosclerosis and reduce blood viscosity.Hot lemon juice and honey are very effective in treating bronchitis and nasopharyngitis.Gandhi runfei, acid to quench thirst, appetizers and antidotes, whitening, skin, cholesterol.Brewing the remaining, can be applied to the facial treatment of facial spots, powder.
