REOLOGICKÉ CHARAKTERISTIKY MÚK VYMLETÝCH Z ODLIŠNÝCH ODRÔD POTRAVINÁRSKEJ PŠENICE (Triticum aestivum L.)Ladislav Haris, Boris Žitný, Zdenka MuchováActa Univ. Agric. Silvic. Mendelianae Brun. 2010, 58(4), 41-48 | DOI: 10.11118/actaun201058040041 Technological quality was studied of wheat flours from three varieties of Triticum aestivum L. (Arida, Meritto, Verita) delivered to the mill for three years (2007-2009). Physico-chemical parameters observed during the purchase of grain (STN 461100-2) were not significantly different. Also milled flours from tested varieties have by processors required ash content, gluten, acceptable Zeleny index, α-amylase activity (falling number), but as the rheological properties of dough from these flours show, these parameters are unsuited enough (un)suitability of material for efficient processing of flour. Rheological evaluation showed that each variety is suitable for different processing direction. Therefore, if we deliberately separate lots of purchased grain, not only by basic physico-chemical properties listed in the current standards (CSN and STN), but also by their rheological properties, which are important and reliable indicator of the direction of the end-use processing of wheat flours, the flours will be more likely to succeed in specific cereal technology. For the production of bread was satisfactory rheological properties of dough from variety Arida. Verita variety is suitable for processing into wafers, and a variety Meritto for producing biscuits and crackers. Verita and Meritto varieties so do not achieved the expected values of the rheological optimum for "classic" bread processing (bakery products) despite satisfactory gluten content and falling number to use this processing direction. Reported results show us the possibilities of more efficient selection of varieties or lots purchased grain of wheat for use in baking and buscuit industry by using rheological evaluation methods. Results were evaluated by analysis of data exploration (Boxplot, scattering graphs), classical nonparametric testing of hypotheses and the distribution of the data (Wilcoxon test, Kruskal-Wallis, Friedman, rates central tendency and dispersion). |
Vliv předplodiny a diferencovaného hnojení na výnos a obsah N-látek v zrnu jarního ječmeneLuděk Hřivna, Rostislav Richter, Pavel Ryant, Michal PříkopaActa Univ. Agric. Silvic. Mendelianae Brun. 2009, 57(5), 141-148 | DOI: 10.11118/actaun200957050141 In small-plot experiments established in 2001-2004 we studied the effect of the chemical composition of the plant dry matter of spring barley, varieties Kompakt and Jersey, on grain yields. A relatively strong correlation was confirmed between the chemical composition of the plant dry matter and yields. The correlation was most intensive in the case of nitrogen (r = 0.536), phosphorus (r = 0.503), magnesium (r = 0.464) and sulphur (r = 0.431) at the beginning of shooting (DC 30); in the case of potassium (r = 0.557) at the beginning of tillering (DC 23) and calcium (r = 0.530) during ear formation (DC 55). A relatively strong correlation remained from the beginning of tillering to the beginning of ear formation and later decreased. The weather conditions of the year and variety significantly affected grain yields and also the previous crop was important. Grain yields of the variety Kompakt were statistically significantly lower than of the variety Jersey (6.02 t.ha-1 and 6.45 t.ha-1, respectively). The yields of barley grown after sugar-beet were the highest (6.30-6.79 t.ha-1); the grain yields of barley after maize decreased by 9.1-9.7 %. Higher grain yields of the Jersey variety resulted in levels of N-substances (11.35 %) lower than in the Kompakt variety (11.35 % and 11.60 %, resp.). No correlation was discovered between the nitrogen level in the plant dry matter during vegetation and the content of N-substances in barley grain. |

STANOVENÍ KVALITY FERMENTACE PIVOVARSKÉHO MLÁTA SILÁŽOVANÉHO V KOMBINACI S PŘÍDAVKEM SLADOVÉHO KVĚTU A CHEMICKÉHO SILÁŽNÍHO ADITIVAIvo Vyskočil, Petr Doležal, Jan Doležal, Václav Pyrochta, Libor KalhotkaActa Univ. Agric. Silvic. Mendelianae Brun. 2008, 56(5), 227-234 | DOI: 10.11118/actaun200856050227 The aim of the work was to evaluate the effect of addition of humidity absorbent (malt sprouts) and chemical conservation additive on fermentation process quality of brewer grains' silage. Chemical conservation additive was based on formic acid, propionic acid, benzoic acid and ammonium formate content. In a model experiment the fresh brewer grains were used. A dry matter (DM) content of brewer grains was 187.4 g/kg. Six treatments with three repetitions per treatment were prepared. The treatments A1, A2 and A3 were not supplied by humidity absorbent. Treatment A1 was a control treatment without any additive. The treatments A2 and A3 were supplied by chemical conservation additive in a dose of 3 L per tonne and 6 L per tonne, respectively. The treatments B1, B2 and B3 were supplied by malt sprouts to reach DM content of conserved matter on level 320-350 g/kg. Moreover the treatments B2 and B3 were supplied by chemical additive with its dose 3 and 6 L per tonne. Model silages were evaluated after 8 months of conservation at average laboratory temperature 26-28 °C, from each treatment were the final laboratory samples taken and analyzed. During conservation of treatments B1, B2 and B3 were no drain recognized. From A1 treatment drained 1300 ml of waste fluid that is 145 L per tonne of conserved matter. That was significant (P < 0.01) the malt sprouts addition support the lactic acid production and eliminate acetic acid production. There was no propionic acid or butyric acid detected in silages with malt sprouts event in these silages were analyzed higher (P < 0.01) concentration of ammoniac. Chemical additive supplementation improved (P < 0.01) the pH value and water leach acidity. The results show the malt sprout addition eliminates waste fluid drain and improves fermentation process. The higher concentration of chemical additive (6 l/t) inhibited the fermentation process in our model experiment. |

Mendelianae Brun. 2008, 56(2), 139-146 | DOI: 10.11118/actaun200856020139 The aim of this study was to evaluate the effect of a chemical preservative supplementation on the quality of lupine silage as compared with untreated controls. Fresh green Lupine (Lupines lupine), variete Juno, dry matter content 187.15 g/kg at full waxy stage of maturity were chopped to the legth of cut ca 30-50 mm. The crop was artificially wilted for a periody 24 h and ensiled as described above. Lupine were ensiled for 98 days in laboratory silos, capacity about 4 l alone or with supplementation of chemical preservative 3 and 6 l/tone forage respectively). The relatively mean WSC content and the low buffering capacity of lupine crop provided for a good preservation with the chemical preservative. |
