Chemische Eigenschaften
4-Hydroxy-3-methoxybenzoic acid has a vanilla-like odor and taste.
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.
Verwenden
A flavoring agent.
Verwenden
Vanillin, a compound widely used in foods, beverages, cosmetics and drugs, has been reported to exhibit multifunctional effects such as antimutagenic, antiangiogenetic, anti-colitis, anti-sickling, an d antianalgesic effects. However, results of studies on the antioxidant activity of vanillin are not consistent.
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
