I. GRUBECKI, A, ZALEWSKA: Optimal feed temperature in a fixed-bed reactor for hydrogen peroxide decomposition by immobilized Terminox Ultra catalase: Plug flow case
Inż. Ap. Chem., 2017, 56, 5, 166-167
The optimal feed temperature was determined for a non-isothermal fixed-bed reactor used in hydrogen peroxide decomposition by immobilized Terminox Ultra catalase. The feed temperature was obtained by maximizing average substrate conversion under the constant feed flow rate and temperature constraints. Calculations were based on kinetic and mass transfer parameters determined for the process carried out in the model reactor. The simulation showed that the optimal feed temperature was strongly dependent on hydrogen peroxide concentration, amount of enzyme used, superficial velocity and diffusion resistance expressed by the biocatalyst effectiveness factor.
Keywords: hydrogen peroxide decomposition, Terminox Ultra catalase, optimal feed temperature, plug flow reactor

J. KASPRZAK: Environmental implications of slaughterhouse blood disposal as waste from meat industry
Inż. Ap. Chem., 2017, 56, 5, 168-169
Problems dealing with animal slaughter blood disposal (pork-beef and poultry) are described. Key issues concerning formation and disposal of slaughter blood are characterized. Technological possibilities of using blood and its derivatives (blood plasma and hemoglobin) are demonstrated in a variety of applications, including those in feed industry. An attempt of assessment of environmental effects of such treatment using a life-cycle assessment method compared with the utilization of this waste was also performed.
Keywords: slaughter blood, plasma, hemoglobin, LCA

J. KOWALIK, M. KURAS: Effect of pulping degree of cellulose sulfate mass on paper strength parameters
Inż. Ap. Chem., 2017, 56, 5, 170-171
The effect of pulping degree of high-performance sulfate mass on the strength properties of kraft paper is presented. Effects of cellulose mass grinding obtained in a laboratory PFI mill with industrial conical mills were compared. The produced paper sheets were subjected to, among others, tensile and homogeneity tests. It was found that grinding in the PFI laboratory mill had a more favorable effect on pulp fibers fractionation. Paper strength properties such as flatness, elongation, and puncture index were higher when using a PFI grinder.
Keywords: cellulose mass, pulping, paper strength

J. PACIOREK-SADOWSKA, M. BOROWICZ, B. CZUPRYŃSKI, J. LISZKOWSKA, E. TOMASZEWSKA: New polyurethane composites using biodegradable polymer
Inż. Ap. Chem., 2017, 56, 5, 172-173
Researches on the use of waste polylactide in the production of rigid polyurethane-polyisocyanurate foams were performed. Polylactide was obtained as byproduct of 3D printing. The effect of microspheres content (from 0% to 10 wt %) on the properties of synthesized rigid PUR-PIR foams was tested. The use of polylactide as a filler in the production of PUR-PIR foams reduces their brittleness, flammability and softening temperature. However, it increases density and compressive strength of foams compared to the reference foam.
Key words: rigid polyurethane-polyisocyanurate foams, fillers, polylactide

K. PEPLIŃSKI: Use of ANSYS-Polyflow software to support the production of preformed blow molded packaging
Inż. Ap. Chem., 2017, 56, 5, 174-175
Numerical software is useful tool in obtaining blow molded products. The paper presents an exemplary application of ANSYS-Polyflow software to achieve the expected thickness distribution in the final packing during blowing a PET preform. The effect of blowing pressure on time until the blowing preform was fully contacted with the mold was also assessed. Numerical studies carried out for assumed assumptions enabled one to achieve a product with the smaller thickness distribution and shorter preform blowing phase.
Keywords: blow molding, perform, bottle, simulation, ANSYS-Polyflow

I. PIASECKA, P. ROPIŃSKA, A. TOMPOROWSKI, M. GIE-REMEK: Evaluation of possible application of crushed grains of selected cereals for energy purposes
Inż. Ap. Chem., 2017, 56, 5, 176-177
The aim of this research was to evaluate the possibility of using crushed grains of selected cereals for energy purposes. The granulometric particle size distribution of grains crashed in a multilayer mill was tested using the Camsizer analyzer. The calorific value of grains was evaluated employing the calorimeter. It was found that crushing of cereal grains influences their energy value. The grain samples have a similar calorific value as poor or medium quality hard coal.
Key words: grain alleged, biomass, renewable energy sources, comminution

A. REWOLIŃSKA, K. PERZ: Example of face seal selection for the selected application in food industry
 Inż. Ap. Chem., 2017, 56, 5, 178-179
Using the algorithm proposed in the earlier paper a selection of face seal for the water transportation pump is presented. Data necessary for the selection can be found in manufacturer's website for seals. A front-facing seal with the rotating housing, mounted inside the hull with hydraulic relief was selected for given operating conditions. The next step was to check limits for seal operating parameters such as pressure, temperature and rotational speed with respect to materials and solutions used.
The presented analysis and seal selection was of a simplified character.
Keywords: face seal, selection, water, centrifugal pump

M. RUSZKOWSKA, P. KROPISZ: Characteristics of gluten-free bread made of unconventional flour
Inż. Ap. Chem., 2017, 56, 5, 180-181
Eight variants of gluten-free bread with varying amounts of unconventional flour were baked under laboratory conditions and analyzed. Corn flour, rice flour, oatmeal, coconut and tapioca flour were used as baking flour. The characteristic of bread was based on the assessment of its physicochemical properties (water content and water activity, swelling and porosity) and on organoleptic assessment. It was found that some baked variations of gluten-free unconventional flour did not meet all physicochemical requirements (specified in the standard) typical for gluten-containing bread.
Keywords: gluten-free bread, unconventional flour, bread phy-sicochemical properties, organoleptic assessment of bread

M. RUSZKOWSKA, K. NOWICKA: Culinary characteristic of unconventional pasta
Inż. Ap. Chem., 2017, 56, 5, 182-183
A quality of unconventional gluten-free pasta based on the characteristic of selected culinary properties and sensory evaluation is presented. The culinary characteristics of pasta tested were determined on basis of optimum cooking time, weight gain, dry matter loss ratio and organoleptic assessment. Evaluation of tested products was also extended including the determination of water content and activity of products before cooking. The research material consisted of 8 macaroni: sea algae pasta, black soybean pasta, black rice pasta, red lentil pasta, buck-wheat pasta with amaranth and chickens, nettle noodles and quinoa pasta with organic spices. The evaluated unconventional pasta differed in nutritional value and raw material composition. On basis of comparative assessment it was found that the highest quality was characterized by red lentil pasta. However, the most sensible parameters determined by sensory evaluation were found for buckwheat noodles with sweet potatoes, nettle noodles and quinoa pasta with organic spices.
Keywords: unconventional gluten-free pasta, culinary assessment, sensory evaluation

A. ZALEWSKA, I. GRUBECKI, J. MICHAŁKO: Particle size distribution of selected emulsions depending on emulsifier content
Inż. Ap. Chem., 2017, 56, 5, 184-185
The effect of emulsifier content on particle size distribution in the mixture of mint and eucalyptus oils and vitamin A was studied. The systems were homogenized at a constant stirrer rotational seed. HELOS BR laser diffractometer was used in research. It was proved that the Sauter and volumetric mean diameters, and consequently, the better homogenization of mixture were smaller for the higher emulsifier concentration.
Keywords: emulsion, particle size distribution, mint oil, eucalyptus oil
