BORDENAVE, Sylvia A; DUCE, Jorge A  y  YBARRA, Liliana R. Parameters of hygienic - sanitary quality for elaborated yerba mate. Rev. cienc. tecnol. [online]. 2011, n.15, pp.61-65. ISSN 1851-7587.

The researcg of the hygienic-sanitary quality of 60 different trademarks of elaborated yerba mate was carried out to determine standard parameters that could be proposed as reference. The counting of microorganisms: total aerobic mesophilic, total and faecal coliforms, fungi and yeasts was carried out in the samples following the techniques proposed by IRAM Norms. In 61% of the samples, values of total aerobic mesophilic < 3000 UFC/g were found. In fungi and yeasts, 63, 33 % of the trademarks present values < 500 UFC/g and in a 60% of these trademarks the value of total coliforms is < 100 NMP/g. Faecal coliforms were not found. In view of the values found, it is suggested that elaborated Yerba Mate be initially adjusted to the < 1000 UFC/g limits, for aerobic total mesophilic intervals < 100 NMP/g, and that faecal coliforms and pathogenic microorganisms should not be present.
