Each line involves one of the combinations of Parmesan's type cheese piece sizes (4 mm, 6 mm) and drying temperatures (30°C and 50°C) and piece size of 8 mm dried in 50°C. Regression lines were compared for five combinations of piece sizes and drying temperatures. The duration of the drying process was ten hours. Regression coefficients in the equations were compared using partial F-test. Multiple pair comparisons were examined by means of SimReg procedure. The latter method allowed to identify pairs of significantly different regression equations as well as pairs of equations that do not differ significantly. A similar analysis was performed for the observations regarding the second drying period (from 5th to 10th hour of drying). In addition to the aforementioned methods also the procedure of determining groups of mutually parallel straight lines was used. The application of that method enabled the division of five equations into two groups.^aWesołowska-Janczarek, Mirosława^cy^ahypothesis testing^amultiple comparisons^aconfidence bands^acheese^aconvection drying Autorzy: , , .

l cleanness of selected resources and ready-made feed mixtures before and after thermal processing. The results indicated that the most bacteriologically contaminated resources were oats (Avena sativa), wheat middlings, wheat (Triticum vulgare), and poultry feed mixture KDKA F35%. The least contaminated were maize (Zea) and Prowit - feed mixture for livestock. The examined feed resources were contaminated with moulds, among which dominated: Aspergillus and Penicillium. The findings of bacteriological and mycological contamination assure instead of allow stating that thermal processing limits microbiological contamination of animal feeds. In order to protect the health of animals as well as consumers it seems advisable to seek new methods of thermal processing in the production of animal feeds to provide their high quality and safety.^aczystość mikrobiologiczna^abacteria^aMikroorganizmy zanieczyszczające pasze stanowią zagrożenia zarówno dla zwierząt, ale także pośrednio dla ludzi poprzez spożywanie produktów pochodzenia zwierzęcego. Celem niniejszej pracy była ocena czystości mikrobiologicznej wybranych surowców oraz gotowych mieszanek paszowych przed oraz po obróbce termicznej. Z przeprowadzonych badań wynika, że najbardziej zanieczyszczonymi bakteriologicznie surowcami był owies, śruta pszenna, pszenica oraz mieszanka paszowa dla drobiu KDKA F35%. Najmniej zaniczyszczeń posiadała kukurydza oraz mieszanka dla trzody Prowit. Badane surowce paszowe zanieczyszczone plesniami, wśród których dominowąły rodzaje: Aspergillus i Penicillium. Uzyskane wyniki badań zanieczyszczenia bakteriologicznego i mykologicznego pozwalają stwierdzić iż proces obróbki termicznej ogranicza zanieczyszczenia mikrobiologiczne pasz. W celu ochrony zdrowia zwierząt oraz konsumentów wydaje się być wskazane poszukiwanie nowych metod obróbki termicznej w produkcji pasz, aby zapewniać im wysoką jakość i bezpieczeństwo.^aobróbka termiczna^amicrobiologiocal purity^apasze^athermal processing^apleśnie

On the Polish market, soybeans come mostly from traditional crops, for this reason its cultivation is much more expensive than soybeans derived from GM crops. Refuse soybean contains a large amount of fat that can be used as an additive enriching animal feed fat. It is however essential first soybeans processing. The extrusion process is one of the processing method refused soybean or whole soybeans as a component in extruded blends. The study used with isolated hulled and unhulled soybeans. From the analysis of the results obtained for the extrudates of mixtures with wheat and corn with addition of soya bean grains, it can be concluded that both the cutting strength and the hardness of the extrudates was higher in the case of corn compound. The greatest ratio of expansion was achieved for the extrudates of wheat and unhulled soya bean compound. The highest hardness was obtained by subjecting to extrusion a mixture of unhulled soya bean meal with corn, while introducing meal of hulled soya bean resulted in extrudates with about 70% lower hardness.^aproces wytłaczania^aextrusion process^auprawa tradycyjna^atraditional crops^auprawa roślin Słowa kluczowe: Słowa kluczowe ang.: ; DOI:

The assessment included such parameters as: ash, fiber, fat, Na, K, Ca and Mg content. Inorganic phosphates, molecular weight and deacetylation degree were also determined. Based on these results a number of differences between substances was identified. The differences are related to varied structure that is due to different methods of two types of chitosan production. The difference in viscosity was the most pronounced parameter. It has been proved the viscosity of fungal chitosan was 5 times lower compared to crustaceous chitosan. The fungal chitosan was characterized with higher deacetylation degree (DD) than crustaceous chitosan. The deacetylation process has significant influence on the structure and chemical parameters of the chitosan. The chemical elements content was differentiation. Relatively low concentration of sodium was identified in the fungal chitosan. However, it contained high levels of nitrogen, fiber and fat when compared to the crustaceous chitosan.^aZagórski, Jerzy^cy^agrzyby^acrustaceous^askorupiaki^aviscosity Autorzy: , .
