Usage

A natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. Citric acid monohydrate is mainly used in the food and beverage industries as a sour agent, flavoring agent, preservative, and preservative. It is also used as antioxidant, plasticizer, detergent in chemical industry, cosmetic industry and washing industry Mainly used as a sour agent for foods, and also for the preparation of medical cooling agents, additives for detergents, etc. Detect bismuth, nitrite, oxygen and water, determine aluminum, copper, mercury, nickel, oxygen and thorium, use it as a sequestrant, remove trace metals, prepare buffer solutions, and determine serum potassium.

Production Methods

1. Starch or sugar (such as sugar cane molasses) as raw material, relaction by fermentation. Potato powder disinfection and fermentation ↓ Aspergillus niger 26 ℃ Filtered mycelial washing Filtrate heating → lime precipitation → sulfuric acid neutralization → decolorization → resin exchange → crystallization → citric acid
2. First 12% ~ 16% potato taro powder sterilization, and then inoculated with Aspergillus pre-cultured mycelium, for fermentation. Adding ammonia water in the fermentation process, separating the hyphae from the fermentation liquor at 26℃ after 2 or 3 days, and adding the water after the mycelium washing to the fermentation liquor. And then heated to 90℃, the use of lime milk precipitation of citric acid, calcium citrate obtained with a little excess of sulfuric acid decomposition of citric acid, filtration, the filtrate with activated carbon decolorization, and then through the ion exchange resin to remove impurities, vacuum 60 ~ 70℃ concentrated, and cooled to not less than 36.6℃ conversion temperature, adding seeds, crystallization, cold air drying, after can get citric acid.
3 .Sugar solution as raw material, with the black yeast fermentation strains, separation, purification. Or extract from citric acid containing fruits, such as lemon juice (citric acid available 5% to 8%), pineapple waste directly.
4. Starchy raw materials such as potato stem, corn and other fermented by Aspergillus niger, and after separation, purification can be made pure.
5. This product is mainly produced by fermentation, the raw materials can be molasses, sucrose, sweet potatoes and petroleum hydrocarbons and other carbohydrates, the general use of fungi for fermentation production. Fermentation can be divided into surface fermentation and deep fermentation of two categories, the surface fermentation is the early production methods, with some of Penicillium or Aspergillus niger as a strain; deep fermentation of Aspergillus also Aspergillus species, the fermentation process In the formation of small spherical polymer aggregates should avoid the production of long and thin silk body, the fermentation conditions for the ph value of 1.5 to 2.8, while the need to pass through the sterile air and with agitation, after the completion of fermentation to remove filamentous bacteria and Residual solid waste, the filtrate calcium carbonate and calcium citrate, and then concentrated sulfuric acid and citric acid in the crude product, then ion exchange resin purification, concentration and crystallization to be finished.
