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...

From the brewery point of view, nitrogen is one of the most significant components of barley. The article sums up the most meaningful pieces of knowledge the forms of abundance of nitrogen in barley, its influence on the quality of barley at of the produced malt. The article contains as well the principles for elaboration of barley with higher protein content. A marginal attention is given to the influence of malt on the quality and the sensoric stability of beer.From the brewery point of view, nitrogen is one of the most significant components of barley.

Haze of turbidity is optical property of solid, gaseous and particularly liquid matter. It is due to various types, quality and size of particles from submicrometer to submilimeter dimensions which scatter light. Light scattering used also to determine the haze of turbidity of matter. The magnitude of measured haze depends on both properties of haze forming particles and measuring light scattering probe. These properties and relations are generally nonlinear and complicated. This is valid particularly in the case of haze of beer, brewing intermediates and other beverage products which bear the character of liquid dispersions. Correct and effective...
