High hydrostatic pressure is a non-thermal food processing technology that is found to increase the percentage of germination, decrease the germination time and improve the microbial quality of seeds. In this study, pressures of 100-400MPa for 10min at 30 degrees C are used to compare the percentage of germination, the microbial quality of seeds, chlorophyll a and b, and total phenolic compounds concentrations in seedlings, and the anatomy-morphology characteristics of garden cress. Enhanced reductions of total aerobic mesophilic bacteria, total and fecal coliforms, and yeast and mould populations in seeds were observed, especially at 300MPa. In addition, the percentage of germination, chlorophyll content and phenolic compounds concentrations, fresh and dry weights, and hypocotyl lengths of the seedlings are higher than those of all samples, where the percentage of germination is equal to controls but higher than other samples, and radicula length is lower than controls but higher than others.

The effect of chitosan-based edible film and high hydrostatic pressure process on the microbiological and chemical quality of rainbow trout (Oncorhynchus mykiss Walbaum) fillets during cold storage (4 +/- 1 degrees C) Guenlue, Ali; SIPAHIOGLU, Sinem; Alpas, Hami (Informa UK Limited, 2014-01-02) The objective of this study is to determine the changes in the chemical and microbiological quality of fresh rainbow trout (Oncorhynchus mykiss Walbaum) fillets during storage at 4 +/- 1 degrees C as a result of chitosan-based edible film coating, vacuum packaging and high pressure application processes. Chemical (pH, total volatile basic nitrogen and thiobarbituric acid index) and microbiological (total mesophilic and total psychrophilic microorganism) shelf life analyses were carried out in 4-day interval...
Use of pulsed-high hydrostatic pressure treatment to decrease patulin in apple juice Avsaroglu, M. D.; Bozoglu, F.; Alpas, Hami; LARGETEAU, ALAIN; Demazeau, G. (Informa UK Limited, 2015-04-03) This study was aimed at reducing patulin content of apple juice using a non-thermal method, namely pulsed-high hydrostatic pressure (p-HHP). Commercially available clear apple juice was contaminated artificially with different concentrations of patulin (5, 50 and 100 ppb). Then, the samples were processed 5 min at different pressure treatments (300-500 MPa) in combination with different temperatures (30-50 degrees C) and pulses (6 pulses x 50 s and 2 pulses x 150 s). To compare the impact of pulses, single ...
Determination of trapping parameters in n-Ga4Se3S by thermally stimulated current measurements Goksen, K.; Hasanlı, Nızamı (Informa UK Limited, 2009-01-01) Thermally stimulated current (TSC) measurements were carried out on as-grown n-Ga4Se3S layered crystals in the temperature range 10-300 K. The experimental data were analysed by using different heating rates, initial rise, curve fitting and isothermal decay methods. The results of the analysis showed good agreement with each other. The measurements revealed the presence of one trapping level with activation energy of 23 meV. The corresponding capture cross-section and concentration of traps were found to be...
Effect of fiber and resin types on mechanical properties of fiber-reinforced composite pipe Gokce, Neslihan; Yılmazer, Ülkü; SUBAŞI, SERKAN (Thomas Telford Ltd., 2019-09-01) The aim of this study was to evaluate the effects of the types of fiber and resin on the mechanical properties of polyester composite pipes. Orthophthalic, isophthalic and vinyl ester resins were used as the matrix; E-glass, electrical/chemical resistance (ECR)-glass and basalt fibers were used as reinforcement; and 98% silica (SiO2) sand was used as filler in mixtures. Samples were produced by the centrifugal casting method. Samples cut from the produced pipes were tested to determine stiffness and longitu...
Mathematical expression of the temperature profile and experimental determination of compression heating of ethylene glycol during high hydrostatic pressure processing Buzrul, S.; Alpas, Hami; Largeteau, A.; Demazeau, G. (Informa UK Limited, 2007-03-01) In this study, we aimed to describe the temperature profile in the pressure vessel and the compression heating during high hydrostatic pressure (HHP) processing. Regression coefficients (R-2), root mean square error (RMSE) values and residual plots suggested that fourth-order polynomial function produced reasonable fits to define the temperature profile for all the pressures studied (300-600 MPa). If all the coefficients of this empirical model are determined, initial and final temperatures, a value close t...
