Calcium tartrate is then converted to tartaric acid by treating the salt with aqueous sulfuric acid:. Racemic tartaric acid i.
In the first step, the maleic acid is epoxidized by hydrogen peroxide using potassium tungstate as a catalyst. Dihydroxymaleic acid can then be oxidized to tartronic acid with nitric acid.
Important derivatives of tartaric acid include its salts, cream of tartar potassium bitartrate , Rochelle salt potassium sodium tartrate, a mild laxative , and tartar emetic antimony potassium tartrate.
Tartaric acid is a muscle toxin , which works by inhibiting the production of malic acid , and in high doses causes paralysis and death.
As a food additive , tartaric acid is used as an antioxidant with E number E ; tartrates are other additives serving as antioxidants or emulsifiers.
When cream of tartar is added to water, a suspension results which serves to clean copper coins very well, as the tartrate solution can dissolve the layer of copper II oxide present on the surface of the coin.
The resulting copper II -tartrate complex is easily soluble in water. Tartaric acid may be most immediately recognizable to wine drinkers as the source of "wine diamonds", the small potassium bitartrate crystals that sometimes form spontaneously on the cork or bottom of the bottle.
These "tartrates" are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through cold stabilization which is not always preferred since it can change the wine's profile.
The tartrates remaining on the inside of aging barrels were at one time a major industrial source of potassium bitartrate.
Tartaric acid plays an important role chemically, lowering the pH of fermenting "must" to a level where many undesirable spoilage bacteria cannot live, and acting as a preservative after fermentation.
In the mouth, tartaric acid provides some of the tartness in the wine, although citric and malic acids also play a role. Results from a study showed that in citrus, fruits produced in organic farming contain higher levels of tartaric acid than fruits produced in conventional agriculture.
Tartaric acid seems to increase the critical temperature in certain superconductors , by supposedly raising the oxidation grade, while the mechanism of this phenomenon is still not precisely known.
Tartaric acid and its derivatives have a plethora of uses in the field of pharmaceuticals. For example, it has been used in the production of effervescent salts, in combination with citric acid, to improve the taste of oral medications.
Tartaric acid also has several applications for industrial use. The acid has been observed to chelate metal ions such as calcium and magnesium.
Therefore, the acid has served in the farming and metal industries as a chelating agent for complexing micronutrients in soil fertilizer and for cleaning metal surfaces consisting of aluminium, copper, iron, and alloys of these metals, respectively.

Solubility in water. Other cations. 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. Tartaric acids and the common tartrate salts are all colourless, crystalline solids readily soluble in water.
In food it is used as: an antioxidant where as a synergist it increases the antioxidant effect of other substances: for adjusting acidity in frozen dairy products, jellies, bakery products, dried egg whites, sweets, beverages, jams and preserves and wine: diluting food colours: as a sequestrant, chemically combining with undesirable oxidants and rendering them inactive: an acid in some baking powders.
Can also be found in cocoa powders, sweets and tinned asparagus, fruit and tomatoes. Found in cheese, sponge cakes and Swiss rolls, ice cream, jams, jellies, margarine, marmalades and sweets.
Vegetarians should be aware that as the source, E , Lactic acid, is a naturally occurring animal product it could conceivably be of animal origin.
E Potassium lactate. E Calcium lactate. Particularly used in tinned fruits and vegetables where it inhibits discolouration and, because of its reaction with the naturally present pectin, forming the less water soluble calcium pectate, helps prevent the structural collapse of the food.
Improves properties of milk powders and condensed milk. Also used for its synergistic effect on other substances antioxidant effect. As well as the aforementioned can be found in jams, jellies, and marmalades.
E Citric acid. The most versatile and widely used organic acid in foodstuffs, citric acid is a colourless, crystalline organic compound, belonging to the family of carboxylic acids.
It is present in practically all plants, and in many animal tissues and fluids, but it is in particularly high concentrations in lemons and other citrus juices and many ripe fruits.
First isolated in from lemon juice, by the Swedish chemist Carl Wilhelm Scheele, citric acid has been used as a food additive for over years. It is normally manufactured by fermentation of cane sugar or molasses in the presence of the fungus Aspergillus niger , but it can also be obtained from pineapple by-products and low-grade lemons.
Its use as a food additive is wide and varied - as a synergist to enhance the effectiveness of other antioxidants; as a sharp-tasting flavouring; as a sequestrant in foods it combines with the naturally occurring trace metals to prevent discolouration and in wine production it combines with free iron to prevent the formation of iron-tannin complexes which cause cloudiness; in brewing to reduce excess losses of sugars from the germinated barley; to create an acidic environment to discourage the growth of certain bacteria, yeasts and moulds and in cheese making it produces a faster and more consistent method of producing the necessary acidic environment for the enzyme activity than the traditional souring by lactic acid E caused by bacteria.
Because of this versatility it can be found in a wide range of products, including non-alcoholic drinks, bakery products, beer, cheese and processed cheese spreads, cider, biscuits, cake mixes, frozen fish particularly herrings, shrimps and crab , ice cream, jams, jellies, frozen croquette potatoes and potato waffles, preserves, sorbets, packet soups, sweets, tinned fruits, sauces and vegetables and wine.
Recorded problems are that it can be a local irritant and in large amounts can cause teeth erosion. However there have been erroneous reports that it is a major cause of cancer.
It is thought that this has been brought about by misunderstanding and confusion over the word Krebs.
