The content of contaminants in the brewing barley of the Czech Republic 1999 crop.

Based on other of the Ministry of agriculture of the Czech Republic, a research was worked out on the content of the most important contaminants that could permeate from the brewing barley into beer. Fifty samples from the Czech brewing barleys reaped in 1999 were analyzed for the content of volatile N-nitrosamines, heavy metals (As, Hg, Pb, Cd, Ni, Cr, Cu), polyaromatic hydrocarbons, biogenic amines and, in cereals the most frequent mycotoxines and pesticides as regards beer, these are the most important contaminations that could pass from barley, most commonly recorded as positive in beer and prescribed by the pursuing public notice No. 298/1997 Coll. to the Act on Food No. 110/1997 Coll. In the total, more than 1200 analyses were carried out. The results were compared with the prescribed limits, statistically assessed and the risks for the production of malt and beer were rated.Based on other of the Ministry of agriculture of the Czech Republic, a research was worked out on the content of the most important contaminants that could permeate from the brewing barley into beer.
