The effect of convective drying temperature (Td), air velocity (v), rehydration (Tr), and kind rehydrating medium (pH) was studied on the following apple quality parameters: water absorption capacity (WAC), volume ratio (VR) color difference (CD). To model, simulate, optimize parameters processes hybrid methods artificial neural network multiobjective genetic algorithm (MOGA) were developed. MOGA adapted to tissue, where simultaneous minimization CD VR maximization WAC considered. range...

Abstract The purpose of the study was to establish relationship between different sensory attributes wild boar meat, as well develop a prediction model demanded. analysis 40 samples meat (the loin) performed. For tenderness, juiciness, colour, taste, aroma, and off-flavours are significantly correlated with general quality assessed by panel. results from indicate that reveals characteristic traits; however, texture do not play an important role in creating quality, but most factors...

Fruit and vegetable processing has a significant impact on the environment due to its consumption of amount water. Water mainly depends type production technology used. in fruit plants is used as raw material, an energy carrier, hydro transport, well for washing materials maintaining hygiene. The variety technological operations carried out process seasonality make it difficult objectively assess use water plants. Few available publications this field provide numerical values unit indices,...

Cognitive deficits are one of the frequent symptoms accompanying epilepsy or its treatment.In this study, effect on cognition intraperitoneally administered antiepileptic drug, pregabalin (10 mg/kg), was investigated in scopolamine-induced memory-impaired mice passive avoidance task and Morris water maze task. The scopolamine animals' locomotor activity also studied.In retention phase task, reversed memory induced by (p < 0.05). During acquisition pregabalin-treated performed test with...

The objective of this paper was to create a mathematical model vacuum drops in form that enables the testing impact design parameters milking cluster on values claw. Simulation tests were conducted, with use simplified fourth-degree polynomial. Sensitivity analysis and simulation structure claw carried out. As result, machine’s process could be analysed. results showed change local loss linear drag coefficient long milk duct will have lower if smaller flux inlet air, higher head air/liquid...

This paper presents a multi-objective optimization method for optimizing the process parameters during friction welding of dissimilar metals. The proposed combines response surface methodology (RSM) with an genetic algorithm (GA) method. Ultimate tensile strength (UTS), flash diameter and heat affected zone (HAZ) width welded nodular cast iron low carbon steel joints were investigated considering following parameters: pressure (FP), time (FT) upsetting (UP). Mathematical models developed...

Fruit and vegetable processing comes 6th in terms of energy consumption the agri-food industry. At same time, 88.4% industry’s final structure is thermal energy, which depends heavily on electricity consumption. In addition, fruit has a significant impact environment due to amounts water. Reducing these three indicators simultaneously would increase efficiency process while improving environmental protection. This paper proposes neural models water for selected major fruit-...
