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. Tartaric acids and the common tartrate salts are all colourless, crystalline solids readily soluble in water.
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. Citric acid is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.
This series of chemical reactions, which is central to nearly all metabolic reactions and the source of two-thirds of the food-derived energy in higher organisms was discovered by the German-born British biochemist Sir Hans Adolf Krebs.
He actually received the Nobel Prize for Physiology or Medicine for the discovery, and as well as being known as the tricarboxylic acid cycle its correct name , it is also known as the citric acid cycle or the Krebs cycle.

The acid has been observed to chelate metal ions such as calcium and magnesium. In practice, higher yields of calcium tartrate are obtained with the addition of calcium chloride.
