The influence of furanogen substance (proteins and pentosans) from hops was such as to cause in beer a more pronounced separation of middle-molecular protein fraction B. The negative influence of long preparation of wort with hops as well as the advantage of the use of hops extractors has been thus proved. The negative influence of furanogen substance and some fractions of proteins has not been proved with certainty.(In Czech, English summary only)

The author recapitulates development of fusel oil separators and describes those used in ČSR. He comes to conclusion, that the simplest and cheapest separator with only one washing produces fusel oil of unsatisfying quality, yet by means of sequent decantation in a suitable decantation tank with conic bottom its quality can be raised as to meet the prescribed standard.(In Czech, English summary only)
