The aim of these studies was to assess the effect of chemical conservants (FA = formic acid, PA = propionic acid, FPA+i = formic acid, propionic acid and ammonium ions) on the cell counts of yeasts and mould fungi in silage. The silage was prepared from corn (Zea mays L), cultivar Buran FAO (240). The effect of the applied conservants on silage aerobic stability was also assessed. The performed chemical analyses comprised the determination of: the content of dry matter (DM), lactic acid (LA), acetic acid (AA), ethanol, water soluble sugars (WSC), crude protein (CP) and pH. The applied preparations were found to reduce the number of yeast and mould fungi cells in all the examined silages. The growth of fungi was inhibited most strongly by the FPA+i preparation (containing a mixture of formic and propionic acids and ammonium ions). The yeast cell counts dropped (P«0.05) from 8.50 107 CFU g-1 silage in the control (CCS = control corn silage) to 2.60 107 CFU g' in silage treated with FPA+i, whereas counts of the mould fungi cells - from 15.20 104 CFU g-1 silage in the control to 4.60 104 CFU g-1 in silage treated with FPA+i. The applied conservants increased (P«0.05) the content of DM from 255.00 g • kg 1 in control to 266.60 g • kg-1 with PA, WSC from 27.10 g • kg 'DM to 30.50 g • kg -1DM with FPA+i and ethanol from 9.10 g • kg 'DM to 11.21 g • kg -1DM with FPA+i in the silage. The additives decreased concentrations of lactic acid, acetic acid and crude protein concentration after opening the barrels. The diversifying factors decreased the pH value in the examined silage. The experimental conservants were found to improve the aerobic stability of silages after 7 days of air exposure.

Celem pracy było określenie wpływu fizycznej i amylolitycznej modyfikacji ziarna kukurydzy na zawartość wybranych składników w uzyskanych produktach. Materiałem badawczym były ziarna kukurydzy handlowej typu flint, odmiany Delitop, poddane przemiałowi „na sucho”. Uzyskano cztery asortymenty przemiału ziarna kukurydzy: łom (2,5- 6,0 mm), kaszę (0,75- 1,25 mm), kaszkę (0,25-0,75 mm), mąkę (< 0,25 mm), które wraz z ziarniakiem (około 10 mm) stanowiły pięć surowców poddanych modyfikacji amylolitycznej i fizycznej. Zaproponowana w niniejszej pracy modyfikacja amylolityczna, polegająca na hydrotermicznej obróbce mieszaniny reakcyjnej enzymami amylolitycznymi (jednoczesne działanie α-amylazy i amylazy maltogennej) wraz z modyfikacją fizyczną, polegającą na rozdziale zawiesiny poreakcyjnej na dwie fazy, umożliwia otrzymanie nowych modyfikatów ziarna kukurydzy lub produktów jego przemiału, charakteryzujących się zmienioną zawartością wybranych składników (zwiększenie zawartości białka i tłuszczu, zmniejszenie zawartości skrobi). Uzyskane modyfikaty kukurydziane – ze względu na zawartość wybranych składników – mogą być stosowane jako składniki wyrobów spożywczych, a także jako komponenty mieszanek paszowych.

The research defined the effectiveness of corn fertilisation with nitrogen depending on its content in soil and covered N uptake, agronomical and physiological fertilisation efficiency as well as coefficients of nitrogen-fertliser utilisation. Spring and autumn doses were defined which were applied to balance N fertilisation and uptake by plants as well as the degree of N utilisation from the same doses applied in autumn and spring. As for the plant dry matter yield, the agronomical and physiological efficiency of all the spring N doses at 160 and 240 kg×ha-1 introduced into the soil in autumn were negative, and the coefficient of nitrogen utilisation against other fertilisers did not exceed 7.4%.

Corn was grown for green matter in a pot experiment, in which soil was fertilized with composts alone or in combination with 3 g N per pot (urea). The composts were made in wooden boxes, measuring 50×60×60 cm. They were composted for 3.5 months, until the temperature in the composts became stable and equal to the ambient temperature. Rates of the composts were balanced with amounts of added nitroge, such as 6.0 g N per pot. A one-factor experiment was conducted in Kick-Brauckmann pots, kept in a greenhouse at the University of Warmia and Mazury in Olsztyn. After harvest, fresh matter of stems and leaves as well as corn cobs was determined. Next, the plant samples were dried to determine the dry matter content and finally, after mineralisation, the concentration of Cu, Zn and Mn was determined by atomic absorption spectrophotometry. The composts significantly reduced the concentration of zinc and manganese in the vegetative yield of cor (lstems and leaves). Urea applied in combination with the composts very strongly increased the concentration of manganese and, to a lesser degree, the level of zinc and copper in vegetative organs. In corn cobs, the application of urea increased only the content of manganese. Urea had a stronger effect on increasing the weight of cobs rather than the vegetative mass of corn plants. The uptake of Cu, Zn and Mn was more evidently conditioned by the accumulation of these elements in dry matter than by the total weight of corn plants. The extent of the relationship between the uptake of Cu, Zn and Mn and their concentration of corn biomass is expressed the by corresponding correlation coefficients: 0.66, 0.65 and 0.68.

The paper discusses the influence of the addition of freeze-dried tomatoes on the chemical composition and selected physical properties of extruded corn snacks. Corn grits were replaced with dried tomatoes in the amount from 5 to 30% of corn mass. The total lycopene and phenolic content, the scavenging ability and the ferric reducing antioxidant power were determined along with the content of neochlorogenic, chlorogenic, p-coumaric acids and rutin. Also evaluated were selected physical properties, colour and the sensory profi le of corn snacks enriched with tomatoes. A greater tomato addition increased the volume of bioactive compounds, especially the total phenolic content. Snacks enriched with tomato exhibited a lower expansion ratio, water absorption and solubility indices, lightness and sensory characteristics but higher density, hardness and redness than corn snacks. Powdered tomato seems to be a functional additive with the high content of biologically-active compounds, and the enriched snacks displayed good physical properties if the tomato level did not exceed 20%. A higher amount of the additive signifi cantly lowered the expansion as well as increased the hardness of snacks. Still, the corn products with 25 and 30% of powdered tomato were more valuable due to their much higher level of bioactive components compared with the regular corn snacks.
