Vinegar test Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening test. It has the potential, say researchers from the University of Zimbabwe and Johns Hopkins University, to improve the chances of preventing cancer in developing world. The technique, termed VIA (Visual Inspection with Acetic Acid)/Cryo, was endorsed by the World Health Organization in 2010. Vinegar is brushed on a woman’s cervix and precancerous spots turn white. These can be instantly frozen off with a metallic probe cooled with
Syringic acid in vinegar. Syringic acid can be enzymatically polymerised. Laccase and peroxidase induced the polymerization of syringic acid to give a poly(1,4-phenylene oxide) bearing a carboxylic acid at one end and a phenolic hydroxyl group at the other. Syringic acid Syringic acid is a naturally occurring "O"-methylated trihydroxybenzoic acid, a type of chemical compound. Syringic acid can be found in "Ardisia elliptica". Syringic acid can be prepared by selectively hydrolyzing (demethylating) eudesmic acid with 20% sulfuric acid. Syringic acid can be found in the açaí palm ("Euterpe oleracea") and its oil (1,073 ± 62 mg/kg). It is also present in wine.
