The acid itself is added to foods as an antioxidant E334 and to impart its distinctive sour taste. Naturally occurring tartaric acid is a useful raw material in organic chemical synthesis. Tartaric acid, an alpha-hydroxy-carboxylic acid, is diprotic and aldaric in acid characteristics and is a dihydroxyl derivative of succinic acid.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
A tartrate is a salt or ester of the organic compound tartaric acid, a dicarboxylic acid.The formula of the tartrate dianion is O − OC-CH(OH)-CH(OH)-COO − or C 4 H 4 O 6 2−. [1]The main forms of tartrates used commercially are pure crystalline tartaric acid used as an acidulant in non-alcoholic drinks and foods, cream of tartar used in baking, and Rochelle salt, commonly used in ...
The acid combines with two molecules of water to produce dihydroxytartaric acid, the ketone hydrate form, C 4 H 6 O 8 or HO−(C=O)−(C(OH) 2) 2 −(C=O)−OH. Indeed, the product traded under the name "dioxosuccinic acid hydrate" appears to be that substance.
Diethyl tartrate is an organic compound with the formula (HOCHCO 2 Et) 2 (Et = ethyl).Three stereoisomers exist, R,R-, S,S-, and R,S (=S,R-). They are the ethyl esters of the respective R,R-, S,S-, and R,S-tartaric acids.
DATEM is composed of mixed esters of glycerin in which one or more of the hydroxyl groups of glycerin have been esterified by diacetyl tartaric acid and by fatty acids. The ingredient is prepared by the reaction of diacetyl tartaric anhydride with mono- and diglycerides that are derived from edible sources.
