Abstract

Balsamic vinegar of Modena is a typical product made from grape must by traditional prodn. method with extensive aging. The presence of biol. active polyphenol components in the vinegar was studied using a modified extn. method. Several extn. procedures and solvents (Et acetate, 4-methylpentan-2-one, isoamyl alc., n-butanol) were tested. The total phenols in exts. were detd. with the Folin-Ciocalteu reagent and expressed as gallic acid contents. The phenolic substances were then fractionated on C18 solid-phase extn. cartridges into neutral and acidic compds. and expressed as gallic acid and (+)-catechin contents, resp.
