sorbic acid
sor·bic acid S0568300 (sôr′bĭk)n. A white crystalline solid, C6H8O2, first obtained from berries of the rowan and now prepared synthetically, used as a food preservative and fungicide.
[From sorb.]sorbic acid (ˈsɔːbɪk) n (Elements & Compounds) a white crystalline unsaturated carboxylic acid found in berries of the mountain ash and used to inhibit the growth of moulds and as an additive for certain synthetic coatings, as of cheese (E200); 2,4-hexadienoic acid. It exists as cis- and trans- isomers, the latter being the one usually obtained. Formula: CH3CH:CHCH:CHCOOH[C19: from sorb (the tree), from its discovery in the berries of the mountain ash]sor′bic ac′id (ˈsɔr bɪk)

TranslationsSorbic Acid
sorbic acid[′sȯr·bik ′as·əd] (organic chemistry) CH3CH=CHCH=CHCOOH A white, crystalline compound; soluble in most organic solvents, slightly soluble in water; melts at 135°C; used as a fungicide and food preservative, and in the manufacture of plasticizers and lubricants. Sorbic Acid (also 2,4–hexadienoic acid), a monobasic unsaturated carboxylic acid of the aliphatic series with the formula CH3CHᆖCH—CHᆖCHCOOH. Sorbic acid is contained in the juice of the berry-like fruit of the mountain ash Sorbusaucuparia. Industry produces only one of the four theoretically possible isomers, namely, trans-trans-sorbic acid; the process involves the condensation of ketene (CH2ᆖCᆖO) together with crotonaldehyde (CH3—CHᆖCH—CHO). Sorbic acid is a colorless, crystalline compound with a melting point of 134°C and a boiling point of 228°C; it is insoluble in water but dissolves readily in alcohol. Sorbic acid is used in organic synthesis and in the preservation of various food products. sorbic acid
