Response Surface Methodology was used to determine the effects of solvent flow rate (1, 3 and 5 g/ min), pressure (300, 375 and 450 bar) and temperature (40, 50 and 60 degreesC) on hazelnut oil yield in supercritical carbon dioxide (SC-CO2). Oil yield was represented by a second order response surface equation (R-2 = 0.997) using Box-Bhenken design of experiments. Oil yield increased with increasing SC-CO2 flow rate, pressure and temperature. The maximum oil yield was predicted from the response surface equation as 0.19 g oil/g hazelnut (34% of initial oil) when 4 g hazelnut particles (particle diameter < 0.85 mm) were extracted with 5 g/min SC-CO2 flow rate at 450 bar, and 60 degreesC for 10 min. Total extraction time at these conditions was predicted to be 35 min.

Effects of high hydrostatic pressure on shelf life of lager beer
BUZRUL, S; Alpas, Hami; BOZOGLU, F (Springer Science and Business Media LLC, 2005-05-01)
Filtered bright lager beer samples were either treated with high hydrostatic pressure (HHP, 350 MPa for 3 and 5 min at 20 C) or conventional heat pasteurization (60 C for 15 min). A storage period of 56 days showed that HHP and heat pasteurization had similar results in terms of pH and color (p<0.05). However HHP-treated samples had lower bitterness and protein sensitivity and higher chill haze values than the heat pasteurized samples at the end of the storage period. The microbiological stability of HHP-tr...
Effect of high hydrostatic pressure and temperature on carrot peroxidase inactivation
Soysal, C; Soylemez, Z; Bozoglu, F (Springer Science and Business Media LLC, 2004-01-01)
The combined effects of pressure and temperature on the activity of carrot peroxidase (POD) were investigated in the pressure range 0.1-600 MPa and the temperature range 25-45degreesC. At lower pressures (<396 MPa), carrot POD stability increased compared to unpressurized samples. Inactivation of 91% was obtained at 600 MPa and 45degreesC. High hydrostatic pressure (HHP) combined with temperature treatment enhanced the inactivation of carrot POD. Regeneration of POD activity with the combined HHP and temper...
Response surfaces of apricot kernel oil yield in supercritical carbon dioxide
Ozkal, SG; Yener, Meryem Esra; Bayindirli, L (2005-01-01)
Response surface methodology was used to determine the effects of solvent flow rate (2, 3 and 4 g/min), pressure (30, 37.5 and 45 MPa), temperature (40, 50 and 60 degrees C), and co-solvent concentration (0, 1.5 and 3 wt% ethanol) on oil yield of apricot (Prunus armeniaca L.) kernel oil in supercritical carbon dioxide (SC-CO2). All the parameters had significant effects on oil yield as well as the interactions between solvent flow rate and pressure, and between pressure and temperature. Oil yield increased ...
The solubility of apricot kernel oil in supercritical carbon dioxide
Ozkal, SG; Yener, Meryem Esra; Bayindirli, L (Wiley, 2006-04-01)
The solubility of kernel oil from apricots (Prunus armeniaca L.) in supercritical carbon dioxide at 313.15, 323.15 and 333.15 K and at 15, 30, 45, 52.5 and 60 MPa was determined. Appropriate models were fitted to the data and the crossover pressure of apricot kernel oil was found to be between 20 and 30 MPa. Crossover pressure is a pressure value at which the effect of temperature on the solubility changes. Solubility increased as the temperature increased above the crossover pressure but decreased when tem...
Modeling high pressure inactivation of Escherichia coli and Listeria innocua in whole milk
Buzrul, Sencer; Alpas, Hami; Largeteau, Alain; DEMAZEAU, Gerard (Springer Science and Business Media LLC, 2008-06-01)
The survival curves of Escherichia coli and Listeria innocua inactivated by high hydrostatic pressure (HHP) were obtained at room temperature (similar to 22 degrees C) and at five pressure levels (400, 450, 500, 550 and 600 MPa) in whole milk. These curves were described by the Weibull model and parameters of this model were reduced from two to one with slight loss of goodness-of-fit. The logarithm of the time constant parameter (delta) of the reduced Weibull model was described with respect to high pressur...
