    • Characterisation of Selected Apple Cultivars in the Aspect of Juice Production in the Condition of a Farm 

      Nadulski, Rafał; Kobus, Zbigniew; Wilczyński, Kamil; Guz, Tomasz; Ahmed, Zeyad (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      Pressing is the most common method of fruit juice acquisition. Not all apple cultivars are suitable for juice pressing. The use of suitable fruit cultivars for juice pressing may reduce the cost of pressing and at the same ...
    • Effect of Solvent Polarity on the Efficiency of Ultrasound-assisted Extraction of Polyphenols From Apple Pomace 

      Kobus, Zbigniew; Wilczyński, Kamil; Nadulski, Rafał; Rydzak, Leszek; Guz, Tomasz (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      In this paper influence of solvent polarity on the efficiency of ultrasound-assisted extraction of polyphenols from apple pomace was studied. In the experiment, three solvents were used: water, 60% ethanol and 96% ethanol. ...
    • The Effect of Ultrasound on the Rheological Properties of Apple Juice 

      Wilczyński, Kamil; Kobus, Zbigniew; Nadulski, Rafał; Panasiewicz, Marian; Kusz, Andrzej (Department of Machinery Exploitation and Management of Production Processes, University of Life Sciences in Lublin, Poland, 2017-11)
      In this paper, the effect of ultrasonic treatment on the rheological properties of apple juice (Idared variety) was studied. The juice was treated with ultrasonic waves for 5 and 10 minutes relative to the untreated sample. ...
    • Evaluation of Streif’s Index Values During Maturation of Two Apple Cultivars 

      Guz, Tomasz; Kobus, Zbigniew; Nadulski, Rafał; Rydzak, Leszek (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      The paper presents the results of Streif’s Index (SI) expression by new method of harvest date optimization, based on calculation one of its components - starch index (S), by image analysis. Harvest date prediction is a ...
    • The Influence of Wheat Hardness on Energy Consumption During the Wheat Milling 

      Ahmed, Zeyad; Nadulski, Rafał; Panasiewicz, Marian (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      Wheat is generally used for a food after converting grain components into different degrees of flour. The perfect milling operation needs to get enough knowledge about kernel mechanical properties and mainly hardness, to ...
    • Modification of Rheological Properties of Biofuels From Soybean Oil 

      Kobus, Zbigniew; Wilczyński, Kamil; Nadulski, Rafał; Guz, Tomasz (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      In this paper, the influence of fuel additives on rheological properties of crude soybean oil was presented. The tests were performed for low shear rates (1.2 - 12.4 s-1) at a temperature range of 5 to 30oC. The fuel ...
    • Texture Changes in Apple Cultivars During Storage in Different Conditions 

      Nadulski, Rafał; Wróblewska-Barwińska, Katarzyna; Domagała, Dorota; Kobus, Zbigniew; Wilczyński, Kamil (Dept. of Mach. Exploit. and Management of Prod. Processes, ULS in Lublin, Poland, 2017-11)
      In Poland, apples are stored in cold storage plants, with either normal or controlled atmosphere. Estimation of physical parameters permits the determination of the current state of the fruit and the prediction of allowable ...
