What is Citric Acid Monohydrate?
Citric acid monohydrate, likewise called citric acid, scientific name 3-hydrocarbyl-3-carboxyglutaric acid, citric acid monohydrate exists in nature in lemons, oranges, plums, plums, pears, peaches, figs, etc. Amongst the fruits, the acid content is greater in the premature ones. Citric acid monohydrate is an anemic translucent crystal or white crystalline powder, odorless, with a strong and also enjoyable sour preference, which gradually weathers in warm air as well as deliquescence in humid air. According to various crystallization conditions, the crystal types include anhydrous citric acid as well as citric acid having crystal water. Business citric acid is mainly anhydrous citric acid as well as citric acid monohydrate. Citric acid monohydrate is crystallized from an aqueous option at a reduced temperature (below 36.6 ° C). The item after separation and drying out has a molecular weight of 210.14, a melting point of 70 to 75 ° C as well as a density of 1.542. Put in dry air, the crystal water in citric acid monohydrate will certainly escape and also weather. Anhydrous citric acid is crystallized in a liquid solution over 36.6 ° C, with a molecular weight of 192.12 and a density of 1.665. The important temperature for the conversion of citric acid monohydrate to citric acid anhydrous is 36.6 ° C.
Citric acid monohydrate is commonly used in the food sector, and also can likewise be utilized as a feed additive, safe cleaning agent, mordant, and so on. At the same time, citric acid monohydrate can likewise be utilized in pharmaceuticals, chemicals, light sector, atomic energy, environmental management as well as other commercial areas, and is additionally an important resources for cosmetics, steel cleaning agents, materials, cardboard, cigarette, electroplating, and so on. The discovery of citric acid monohydrate has a background of greater than 200 years. As early as 1784, somebody first separated citric acid crystals from lemon juice. In 1917, citric acid monohydrate was generated by fermentation of Aspergillus niger, as well as commercial production of citric acid monohydrate began. The commercial manufacturing of citric acid monohydrate in China began in 1963. During that time, there were not many suppliers, as well as the range and output were really little, which can not meet the residential demand. The domestic market remained in short supply and the need depended upon imports. Citric acid monohydrate is a requirement in the food industry as well as entails lots of commercial areas connected to individuals’s lives.
With the development of China’s citric acid monohydrate sector, the items remain to increase, as well as the quality of citric acid monohydrate likewise remains to enhance. Because citric acid monohydrate is mostly utilized in the food market as well as medication, it is related to individuals’s health and life safety, so there are rigorous policies on the high quality demands of citric acid monohydrate. China has likewise created relevant requirements for citric acid monohydrate, which are progressively according to global standards.

Application of Citric Acid Monohydrate
Citric acid monohydrate is in the areas of food industry, medicine, cosmetics as well as dental chemicals due to its non-toxicity, good solubility, delicious sour taste as well as exceptional derivatization.
Citric acid monohydrate is secure as well as safe, and is called the first edible sour representative. It is widely made use of in drink as well as fruit processing, soy products as well as flavoring agents. Citric acid is widely used in jelly, sweet, a glass of wine, and citric acid is contributed to frozen food, which can strengthen the result of anti-oxidants, inactivate enzymes, and ensure the stability of frozen food. Adding citric acid to veggies and seafood can prevent the growth of microbes and lengthen the preservation time. Sodium citrate and potassium citrate are included in jelly, cakes as well as numerous drinks as acidulants, artificial additive, and so on to boost the taste. According to stats, concerning 70% of the complete production of citric acid is used in the food and beverage industry.
Citric acid monohydrate is also commonly used in different nutritional dental fluids to change the pH worth of oral liquids, keep the security of active ingredients, as well as ensure dietary results. In hair shampoos, anti-dandruff shampoos and hair dyes, adding citric acid to readjust the pH worth can increase hair radiance as well as restore hair flexibility when shampooing. Citric acid is contributed to cosmetics and toothpaste to prevent the item from breaking down and ruining.
Citric acid monohydrate also has a vast array of applications in the chemical sector. Citric acid itself is a chemical synthesis intermediate and also the basic material for chemical synthesis. Because of its exceptional buildings, it is commonly made use of as cleaner, stabilizer, chelating representative and defoamer in the chemical sector. Recently, with the improvement of individuals’s understanding of environmental management, sodium citrate is more and more widely utilized to create green and also environmentally friendly phosphorus-free cleaning agents.
Preparation of Citric Acid Monohydrate
The method is to squeeze the juice from the fruits containing citric acid such as immature lemons and citrus, and then mix the juice with lime milk to generate calcium citrate, and then treat it with sulfuric acid to obtain a purer citric acid solution, then The product is obtained by concentration and crystallization.
Since 1784, when the Swedish chemical Scheele first extracted citric acid from lemon juice and crystallized solid citric acid, the natural juice extraction citric acid method became the main method of early citric acid production, which lasted about 50 years. The yield of citric acid produced by this method is low, and the method of extracting citric acid from natural fruit juice was gradually eliminated until the large-scale application of the microbial fermentation method in the middle of the 20th century.
