Opis:: Processes of compaction of granular materials were described using selected models. The analysis of their accuracy on the example of wheat was the basis for the discussion on their applicability to the processing of plant-origin materials. Parameters of the model equations for wheat, compressed at 10-18% moisture content were calculated, and the relations between these parameters and wheat moisture were determined. It was found that the analyzed models described the pressure compaction of granular plant material with different accuracy, and were highly dependent on moisture. The study also indicated that the model of Ferrero et al. fits the experimental results well. The parameters of this model reflected very well the physical phenomena which occur during compression.

Opis:: A possible way to maintain the right level of soil fertility involves using some waste as fertilizer, provided its composition does not violate the pertinent local safety standards. There is currently considerable interest in using meat industry waste, both raw and processed, e.g. meat and bone meal. An experiment on meat and bone meal (MBM) was conducted from 2007-2009 at the research station in Bałcyny (53°36′ N, 19°51′ E), Poland. The aim was to determine the effect of meat and bone meal (MBM) on the content of selected micronutrients in soil as well as in winter and spring wheat grain and in of winter oilseed rape seeds. The effect of MBM fertilizer applied at doses of 1.0, 1.5, 2.0 and 2.5 t ha-1 was compared with mineral fertilization or no fertilization. The experiment did not show any effect of the growing MBM doses on the concentration of micronutrients in soil. As a result of using higher doses of MBM (1.5, 2.0 t ha-1), the content of Cu in 2009 and of Zn in 2007 considerably decreased (2.0 and 2.5 t ha-1). Fertilization with MBM at 2.5 t ha-1 improved the quality of winter wheat grain by increasing the content of Cu, Fe, Mn and Zn. In most cases, the application of MBM increased the content of micronutrients in the grain of spring wheat and seeds of winter rape, although this has not always been confirmed statistically. An analysis of the micronutrient contents revealed a significant decrease in Zn and Fe in winter wheat grain and in Zn in winter oilseed rape seeds as the content of these elements in the soil increased. Regarding the relationship between the Zn content in soil and in seeds of winter oilseed rape, the coefficient of determination was the closest to the coefficient of linear correlation (R2 = 0.931). It was only in 2008 that an increase in the Cu content in winter oilseed rape seeds was determined to have increased parallel to an increase in the micronutrient content in soil. Although the chemical content of MBM implicates its good fertilizer value, the study failed to demonstrate a clearly defined impact of the increased MBM doses on the content of the analysed elements in the soil. This may be attributed to the increase in the bioavailable nitrogen forms, which constitute part of the sorption complex. Their bioavailability may also be subject to mutual relationships among elements, which may act antagonistically (Fe and Mn, Ca and Zn).

Opis:: Do badań użyto mąkę pszenną handlową typu 650 i 850 oraz nasion szarłatu (Amaranthus sp.) spożywczego ze zbioru w latach 1995 i 1996, dostarczone przez PHU Szarłat w Łomży. Nasiona szarłatu ześrutowano i dodawano do mąki pszennej w ilościach 2,4, 6 i 8%. Dodatek śruty z szarłatu spowodował wzrost zawartości białka ogółem. Przy 4% udziale tej śruty w mieszance zmniejszała się zawartość glutenu mokrego, liczba sedymentacji i liczba opadania. Określając właściwości reologiczne ciasta stwierdzono, że dodatek śruty z szarłatu korzystnie wpływał na wodochłonność mąki i wartość walorymetryczną. Ponadto wykazano wzrost początkowej i końcowej temperatury kleikowania oraz lepkości kleiku mącznego przy zwiększającym się udziale śruty. Pieczywo pszenne i z dodatkiem śruty z szarłatu miało prawidłowy wygląd i dobrą jakość. Dodatek śruty nie zmieniał objętości i nadpieku chleba, a poprawiał porowatość miękiszu.
For the tests there were used commercial wheat flour type 650 and 850 and samples of amaranth seeds coming from harvests of 1995 and 1996, supplied by PHU "Szarłat" at Łomża. The amaranth seeds were ground and added to wheat flour at 2,4, 6 and 8%. The addition of amaranth brought about an increase in total protein content. While with 4% addition of amaranth in blend the content of wet gluten, sedimentation value and falling number got decreased. As for rhéologie properties of dough, the addition of amaranth was found to have favourably influenced the water absorption of flour and its valorimetric value. Besides, increasing addition of amaranth was bringing about an increase in the initial and terminal temperature of gelatinization as well as in the viscosity of paste. Both the wheat bread and that with addition of amaranth looked properly and their quality was good. Addition of amaranth did not affect the volume nor overbacke of bread, but it was found to have improved the porosity of crumb.
