    Inactivation Kinetics of Alicyclobacillus Acidoterrestris Spores in Orange Juice by Ohmic Heating: Effects of Voltage Gradient and Temperature on Inactivation
    (International Association for Food Protection, 2010) Baysal, Ayşe Handan; İçier, Filiz
    The effectiveness of ohmic and conventional heating for reducing spores of Alicyclobacillus acidoterrestris was investigated in commercial pasteurized orange juice. The kinetic parameters (D- and z-values) were determined during ohmic and conventional heating. The effects of temperature (70. 80, and 90 °C) and heating time (0, 10, 15, 20, and 30 min) on inactivation of A. acidoterrestris spores during ohmic heating in orange juice were significant (P < 0.05). For 70°C, the voltage gradient also had an effect on inactivation kinetics. At 30 V/cm, D-values at 70, 80, and 90°C were 58.48, 12.24, and 5.97 min, respectively. D-values at corresponding temperatures for conventionally heated spores were 83.33, 15.11, and 7.84 min, respectively. Results showed significantly higher lethality for spores treated with ohmic heating than for spores treated with conventional heating. Conventional heating was ineffective for pasteurizing orange juice, whereas the maximum ohmic heating treatment applied at 30 V/cm was sufficient to inactivate 5 log units of A. acidoterrestris spores.

    Performance investigation of the drying of parsley in a tray dryer system
    (Inderscience Enterprises Ltd., 2010) Hancıoğlu, Ebru; Hepbaşlı, Arif; İçier, Filiz; Erbay, Zafer; Çolak, Neslihan
    The performance of a tray dryer system for the parsley drying process was assessed using energy and exergy analysis methods in this study. The drying temperature ranged from 40°C to 60°C, while the drying air velocity varied from 0.5 m/s to 1.5 m/s. The higher temperature and lower velocity led to higher exergy and energy efficiencies. The exergy efficiency value for the overall system on a product/fuel basis was found to be 3.62%. The values for Specific Moisture Extraction Rate (SMER) and Specific Moisture Exergetic index (SMExR) were obtained to be 0.08 and 2.47 kg/kWh, respectively.
