Food Grade High Quality Citric Acid Monohydrate Powder

Introduction of the product

Forms in which Citric Acid exists:
Citric acid can exist in anhydrous or monohydrate form. The crystalline form of citric acid varies according to the crystallization conditions, slightly weathered in dry air, hygroscopic in humid air, can be decomposed into a variety of products by heating, and can be reacted with acids, alkalis, glycerol and so on. Citric acid anhydrous is crystallized from hot water, while Citric Acid Mondydrate is crystallized from cold water. Citric Acid Mondydrate can be converted to anhydrous citric acid by removing the bound water at about 78 °C. Citric acid is also soluble in anhydrous ethanol at 15 °C (76 parts of citric acid per 100 parts of ethanol) and reacts with ethanol to form ethyl citrate. At temperatures above about 175 °C, citric acid decomposes and releases carbon dioxide.

The use of citric acid
1.Used in food industry
Because citric acid has a mild and refreshing sour flavor, it is mainly used in food additives such as carbonated drinks, fruit juice drinks, lactic acid drinks and other refreshing drinks and pickled products.
2.Used in water treatment industry
Citric acid in water treatment with sterilization, the role of regulating the pH value of water, citric acid acid acidity can change the pH value of cells and affect the normal metabolism of bacteria. Acidic high concentration of hydrogen ions will also change the biological activity of bacteria and directly damage the cells.
3. For chemical reagents, washing
Citric acid can be used as reagents for chemical analysis in chemical technology, as experimental reagents, chromatographic reagents and biochemical reagents; used as a complexing agent, masking agent, used to formulate buffer solutions.
Citric acid or citric acid salts as a detergent, can improve the performance of washing products, can quickly precipitate metal ions, to prevent pollutants from re-adhering to the fabric, to maintain the washing of the necessary alkaline, so that the dirt and ash dispersed and suspended, to improve the performance of surfactants.
Citric acid can also be made into a formaldehyde-free wrinkle finishing agent for wrinkle-free finishing of cotton fabrics.
4. Used in cosmetics
Citric acid has the effect of preventing and eliminating skin pigmentation. Citric acid belongs to a kind of fruit acid, the main role is to accelerate the keratin renewal, commonly used in lotions, creams, shampoos, whitening products, anti-aging products, acne products. The renewal of keratin helps skin melanin peeling, pore refining, blackheads dissolution and so on.
5. For environmental protection
China's rich coal resources, is the main part of the composition of energy, however, has been the lack of effective flue gas desulfurization process, resulting in serious atmospheric SO2 pollution. At present, China's annual SO2 emissions have been nearly 40 million tons, the study of effective desulfurization process, it is imperative. Citric acid - sodium citrate buffer solution due to its low vapor pressure, non-toxic, chemically stable, SO2 absorption rate and other reasons, is a very valuable development of desulfurization absorbent.
6. For livestock additives
Add citric acid in piglet feed, can be weaned earlier, improve feed utilization rate of 5% to 10%, increase sow litter size. In the growth of fattening pig diets add 1% to 2% citric acid, can improve daily weight gain, reduce the feed-to-meat ratio, improve protein digestibility, reduce the thickness of back fat, improve meat quality and carcass characteristics.
7. For sterilization
Citric acid and 80 ℃ degree of joint action has a good bacterial spore killing effect, and can effectively kill hemodialysis machine pipeline contamination of bacterial spores. Enjoy the "King of the West" reputation of lemon has a strong bactericidal effect on food hygiene is very good, coupled with the lemon's fragrant odor, people have always liked to use its production of cold dishes, not only tasty and refreshing, but also to enhance appetite, such as the recent very popular "lemon chicken feet ".
8. Used in medicine
Citric acid, also known as citrate, in the formation of plasminogen activator and the subsequent coagulation process, there must be calcium ions to participate. Citrate ions and calcium ions can form a soluble complex that is difficult to dissociate, thus reducing the concentration of calcium ions in the blood and blocking blood coagulation. It is used as an in vitro anticoagulant in blood transfusions or laboratory anticoagulation of blood samples.

Company information

The company's main import and export products include

(1)Flavors and Fragrances：Fragrance: some from the natural world of plants and animals or by artificial single separate, synthetic and get the fragrance material called fragrance. Flavour: Flavour is a mixture of a variety of fragrances (sometimes also containing a certain amount of solvent) blended out of a certain aroma, can be used directly for product fragrance, can be widely used in perfumes, cosmetics, shower gels and other daily necessities. Simply put, flavours are made from a mixture of various fragrances.

(2)Organic Raw Materials：It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
