Chemische Eigenschaften
white odourless crystals or powder
Occurrence
Reported found in guava, grape, brandy, rum, whiskey, sherry, red and white wines, Scotch and Canadian
whiskey, pork (fried), cocoa, peanuts (raw), mushrooms, guava fruit, mangos (fresh), wort, vanilla and black chokeberries.
Verwenden
Vanillic acid is used as a flavoring agent in food. It acts as an intermediate in the production of vanillin from ferulic acid. Further, it is used in wine and vinegar.
synthetische
Prepared by bioconversion of ferulic acid by means of a vanillate-negative mutant of Pseudomonas fluorescens strain
BS13. Also prepared by whole-cell bioconversion of vanillin to vanillic acid by Streptomyces viridosporus
Definition
ChEBI: A monohydroxybenzoic acid that is 4-hydroxybenzoic acid substituted by a methoxy group at position 3.
Allgemeine Beschreibung
Vanillic acid is one of the key aromatic volatile compounds of vanilla beans.
