Brewery by-products

Spent grain, malt culms and waste yeast are brewery by-products often used as feed for farm animals or production of some food products. As substances contained in the by-products are part of the food chain, the breweries are obliged to monitor their contaminants, particularly aflatoxins B1, B2, G1 and G2 and heavy metals as lead, cadmium, arsenic and mercury, and fluorine. Nutrition parameters as leached extract and proteins are analyzed in spent grain.

Analyses are performed in Analytical laboratories in Brewing Institute Prague and in Malting Institute Brno.
