Biogenic amines are organic compounds (nitrogen bases) of low molecular weight, frequently found in fermented beverages and foods such as cheese, sausage, vegetables, fish, beer and wine, inter alia. Their presence is mainly due to lactic acid bacteria capable to decarboxylate certain amino acids. The physiological characteristics of the amines are varied, as they are essential for the biological functions of the human being, however, its consumption in high concentrations can cause some adverse health effects.Biogenic amines that found in greater abundance in wine are histamine, tyramine and putrescine, present in concentrations ranging from trace amounts to tens of mg/L, which may cause some physiological disorders (e. g. nausea, sweating, headache and hyper or hypotension, inter alia) mainly in sensitive or intolerant people to such compounds.This study aimed to detect oenological lactic acid bacteria able to produce biogenic amines identifying them by mass spectrometry MALDI-TOF. As an initial step, 36 lactic acid bacteria were isolated, characterizing, at the species level, ten of them and two others from different sources; six strains of the genus Lactobacillus (four L. paracasei and two L. brevis) and six of the genus Enterococcus (E. faecium).None of 23 lactic strains studied (among which four L. paracasei and L. brevis) presented the hdcA or sufI gene responsible for producing and degrade histamine, respectively. Moreover, the producing ability of biogenic amines (histamine, tyramine and putrescine) of the twelve bacteria characterized was evaluated in vitro (i. e. growth medium), it was detected by RP-HPLC that no strain occurs histamine and putrescine, however it was found strains of E. faecium and L. brevis can potentially cause certain toxicological risks due to their production of tyramine.Gradually several countries have recommended limits for biogenic amines in wines, which can interfere on international transactions, it is important for Mexico to have the scientific basis to enable it to suggest and rule safe levels of amines to the consumer, by this reason the first work on biogenic amines in Mexican wine is described, which is designed to promote research on this issue nationally and to meet global quality requirements are presented daily in the field of oenology.
