Citric acid anhydrous relative density 1.542, melting point 153 ℃ (dehydration), the refractive index of 1.493 ~ 1.509, E330 is a colorless translucent crystals or white granules, often with part of crystal water, no smell, taste very acid, soluble in water, alcohol and ether. Citric acid anhydrous calcium salt in cold water than hot water easily dissolved, the nature of the citric acid used to identify and separate. Crystallization temperature to control access to the appropriate E330. Acidic aqueous solution. E330 in the dry air of slight weathering in the humid air deliquescence. 175 ℃ above Citric acid anhydrous released by the decomposition of water and carbon dioxide.
Citric acid anhydrous applications:
Citric acid anhydrous for the food and beverage industry, Citric acid anhydrous in the beverage industry as sour agents, flavoring agents, preservatives, E330 is also used for detergents, electroplating and chemical industry as antioxidants, plasticizers, etc. Citric acid anhydrous is an organic acid, found in various fruits and vegetables, but the Citric acid anhydrous is the most concentrated lemon and lime. Citric acid anhydrous is a natural preservative, can also be used to add acid (acid) taste of food and soft drinks. Citric acid anhydrous in biochemistry, it is important as the citric acid cycle or Krebs cycle intermediate, so, Citric acid anhydrous in almost all living creatures, and metabolism. Excess of Citric acid anhydrous easily excreted. E330 is an antioxidant. Citric acid anhydrous can also be used as an environmentally friendly detergent.
