Altogether 158 barley samples were examined, harvested in barley's technological maturity under favourable weather conditions. The barley's were perfectly mature with low germinative power, posesed a characteristic straw odour and colour and remained microbiologically unaffected. Their chemical composition as well as starch, protein and moisture content, however, already witnessed less favourable values compared with those of the previous year' s crop. Under appropiately selected technological malting conditions, the examined barleys render very good modified malts, having satisfactory extractivity with optimal values of the relative extract at45 °C,...

The work outlines a significance of the contaminants, introducing their brief definition under special aspects of the brewing and mailing field. In succession, the following contaminants groups are accounted for: N-nitrosamines (NDMA), total N-nitrocompounds (ATNC), nitrates, heavy metals, mycotoxins, halogenated-hydrocarbons, polycyclic aromatic hydrocarbons, pesticides residues, polychlorinated biphenyls, halogenacetic acids, radioactive substances, purines, biogenic amines, sulfur dioxide and oxalic acid. Each individual group is supplemented with limit values, having a validity in theCzech republicor in EC-countries.(In Czech, English summary only)
