Determinação da origem biossintética de ácido acético através da técnica "Site Specific Natural Isotopic Fractionation Studied by Nuclear Magnetic Resonance (SNIF-NMR)"
Abstract:Recebido em 15/2/05; aceito em 19/8/05; publicado na web em 8/2/06 BIOSYNTHETIC ORIGIN OF ACETIC ACID USING SNIF-NMR. The main purpose of this work is to describe the use of the technique Site-Specific Natural Isotopic Fractionation of hydrogen (SNIF-NMR), using 2 H and 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 acid obtained by fer… Show more
“…Apple cider vinegar (Minhoto®, lot L321B)—which includes 4% maleic acid (40,000 μg/ml) in its composition—manufactured and distributed by Raymundo da Fonte AS® Industries (Paulista, Pernambuco, Brazil) was tested. Regarding the chemical components of the tested substance, we proceeded with a review of the literature, considering studies that performed chromatographic analysis and nuclear magnetic resonance (Table ) . The product was evaluated for the minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC), microbial kinetics, inhibition of adherence of Candida spp.…”
Apple cider vinegar showed antifungal properties against Candida spp., thus representing a possible therapeutic alternative for patients with denture stomatitis.
