Product Description

Production methods

1. Make from starch or sugar (such as sugar cane molasses) as raw material and be prepared by fermentation. Potato powder disinfection fermentation left hyphae of aspergillus Niger 26 ℃ filter washing the filtrate is heated to lime precipitation to sulfuric acid neutralization, decoloring, resin exchange to crystallization, citric acid

2. First, 12 ~ 16% of the potato powder was sterilized, then inoculated with pre-cultured aspergillus Niger for fermentation. Adding ammonia fermentation under 26 ℃, the fermentation of 2 ~ 3 days later, the mycelia and fermented liquid, the water to join the fermented liquid of hyphae after washing. And then heated to 90 ℃, with lime precipitation, citric acid, calcium citrate from USES a bit too much out of citric acid, sulfuric acid decomposition filtration, the filtrate with active carbon decoloring, after ion exchange resin to remove impurities, decompression 60 ~ 70 ℃ under concentrated, cooled to not less than 3

6 6 ℃ temperature, adding seed crystal, crystal, cold and dry, citric acid can be obtained from the finished product.


The pharmaceutical industry is used to prepare citric acid ammonium ferric acid (as a blood transfusion), sodium citrate (as a blood transfusion agent). It can be used as an antidote for alkaline poisoning. The food industry is used to make cool drinks and to be used as candy sours. Electroplating industry is used as a pH adjustment agent for electroplating bath. The printing and dyeing industry is used as an anti – dye agent for vanilin dye. In addition, it can also be used as metal cleaner, oil antioxidant, concrete retarding agent, boiler cleaning agent, non-toxic plasticizer, pipeline cleaning agent, etc. As a chemical reagent, used as a polyvalent chelating agent, used in the preparation of buffer solution, determination of blood potassium, test of bismuth, nitrite, oxygen and water.
