Citric acid anhydrous E330-77-92-9 nature
E330-77-92-9 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. E330-77-92-9 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 E330 released by the decomposition of water and carbon dioxide.
E330-77-92-9 applications
E330-77-92-9 for the food and beverage industry, E330 in the beverage industry as sour agents, flavoring agents, preservatives, E330 is also used for detergents, electroplating and chemical industry as antioxidants, plasticizers, etc. E330 is an organic acid, found in various fruits and vegetables, but the E330 is the most concentrated lemon and lime. E330-77-92-9 is a natural preservative, can also be used to add acid (acid) taste of food and soft drinks. E330 in biochemistry, it is important as the citric acid cycle or Krebs cycle intermediate, so, E330 in almost all living creatures, and metabolism. Excess of E330-77-92-9 easily excreted. E330 is an antioxidant. E330-77-92-9 can also be used as an environmentally friendly detergent.
