Physical and biological treatment of barley seeds
BÁLEK, Václav
Barley is the second oldest cereal after wheat, which began to be cultivated. The area, which was sown with barley in 2015 amounted to nearly 366,000 hectares, which was by 15 thousand hectares more than in the previous year. These numbers indicate that even nowadays it is an important and attractive crop. The aim of my thesis was to study the influence of treating of malt barley varieties Francin by low temperature plasma to technological quality malting barley. It has been evaluated several parameters. Parameters achieved the following results: turbidity 12 ° (10,68 12,15%) and 90 ° (8,86 9,56 %), the viscosity of 8.6% (1,46 mPa), the pH of the wort (5,57 - 5,65), extract flour dry matter (78,2 78,6 %), relative extract at 45 ° C (31,2 33,4 %), the color of the wort (15,5 16,5 j. EBC), nitrogenous substances in dry matter (11,71 12,11 %), soluble nitrogen substances (3,9 4 %), Kolbach index (32,5 34,2 %), beta glucans (69 97 mg/l), diastatic power (147 152 Wk), apparent final attenuation (70 71,8).
