Calcium ascorbate (also known as calcium L- ascorbate ) is the calcium salt of ascorbic acid .
presentation
Calcium ascorbate is industrially synthesized from ascorbic acid, which is obtained by the Reichstein synthesis or possibly using genetically modified organisms .
use
Calcium ascorbate is used as an antioxidant , flour treatment agent and as a color stabilizer . It is used to prevent freshly cut fruit from turning brown ; in the case of meat, it is used in combination with nitrite curing salt to keep the meat from turning red. It is often added to canned fruit and vegetables, fruit juices and nectars, jam, jelly, marmalade, meat and sausage products, as well as bread, baking mixes, beer and wine.
It is generally approved in the EU as a food additive with the number E 302 without maximum quantity restrictions for all foods. It also has comparable approvals in the USA, Australia and New Zealand.
It is also commonly used to increase vitamin C levels. If this is the only reason why calcium ascorbate is used, it can be declared as vitamin C, otherwise it is designated as "E 302" or "calcium ascorbate".
safety instructions
In very high doses, calcium ascorbate can promote the formation of bladder and kidney stones .
