Dangerous Caution Safe

Uses: Metatartaric Acid is used to precipitate excess calcium in wine making. Found in wine, fruit juices, etc.

80% of ingested tartaric acid is destroyed by bacteria in the intestine, with the fraction that is absorbed into the bloodstream being excreted in the urine.

Large amounts can cause gastro-enteritis. No known adverse effects in small quantities.

Mostly safe but they are not allowed in infant food, as infants lack the necessary enzymes to metabolise these compounds.

Description: Metatartaric Acid, present in sugar cane and produced from glucose. It is an acidity regulator and metal scavenger.

In fruit it can be free or either combined with potassium, calcium or magnesium. Sometimes deposited as crystals in wine.

A dicarboxylic acid, also called dihydroxybutanedioic acid, the free acid was first isolated in 1769 by Carl Wilhelm Scheele, although, in a partially purified form tartar was known to the ancient Greeks and Romans.

Most L-tartaric acid is manufactured as a by-product of the wine industry. The sediments, and other waste products from fermentation are heated and neutralised with calcium hydroxide and then the precipitated calcium tartrate is treated with sulphuric acid to produce free tartaric acid.

Can also be extracted from tamarind pulp.
