Abstract

The main purpose of this work is to describe the use of the technique Site-Specific Natural Isotopic Fractionation of hydrogen (SNIF-NMR), using {sup 2}H and {sup 1}H NMR spectroscopy, to investigate the biosynthetic origin of acetic acid in commercial samples of Brazilian vinegar. This method is based on the deuterium to hydrogen ratio at a specific position (methyl group) of acetic acitained by fermentation, through different biosynthetic mechanisms, which result in different isotopic ratios. We measured the isotopic ratio of vinegars obtained through C{sub 3}, C{sub 4}, and CAM biosynthetic mechanisms, blends of C{sub 3} and C{sub 4} (agrins) and synthetic acetic acid. (author)
