Flaxseed protein concentrate containing-mucilage (FPCCM) was used to stabilize soybean oil-in-water emulsions. The effects of FPCCM concentration (0.5, 1.0, 1.5% w/v) and oil-phase volume fraction (5, 10, 20% v/v) on emulsion stability and theological properties of the soybean oil-in-water emulsions were investigated. Z-average diameter, zeta-potential, creaming index and theological properties of emulsions were determined. The result showed that FPCCM concentration significantly affected zeta-potential, creaming rate and emulsion viscosity. The increasing of FPCCM concentration led to a more negative charged droplet and a lower creaming rate. Oil-phase volume fraction significantly affected Z-average diameter, theological properties, creaming index and creaming rate. With the increase of oil-phase volume fraction, both Z-average diameter and emulsion viscosity increased, while creaming index and creaming rate decreased. The theological Curve suggested that the emulsions were shear-thinning non-Newtonian fluids.

Effect of high hydrostatic pressure (HHP) on crystal structure of palm stearin emulsions
Sevdın, Sezen; Yucel, Umut; Alpas, Hami (2017-08-01)
High hydrostatic pressure (HHP) treatment was used to control the crystallization behavior of solid lipid nanoparticles stabilized with sodium caseinate (SC) and soy lecithin Phospholipon 80H (80H). Samples were pressurized at 100 and 500 MPa, at 10, 20 and 40 degrees C for 15 min. The stability of emulsions was analyzed by visual observation for gelation, and the change in the droplet size distribution using light scattering measurements after HHP treatment and storage for 28 days at 4 degrees C. The cryst...
EFFECT OF TANNIC ACID ON GLUTATHIONE S-TRANSFERASE AND NAD(P)H: QUINONE OXIDOREDUCTASE 1 ENZYMES IN RABBIT LIVER AND KIDNEY
KARAKURT, SERDAR; Adalı, Orhan (2011-01-01)
Glutathione S-transferase and NAD(P)H: quinone oxidoreductase 1 enzymes have important roles in detoxification and also activation of a wide variety of chemicals. Moreover, resistance of tumor cells against chemotherapeutic agents has been implicated in GST activities. The aim of this study was to investigate the effect of polyphenolic compound tannic acid on rabbit liver and kidney glutathione S-transferase and NAD(P)H: quinone oxidoreductase 1 enzyme activities. Tannic acid was found to be a potent inhibi...
IMPACT OF PROCESS CONDITIONS ON METHANE PRODUCTION IN ANAEROBIC DIGESTION AND MICROBIAL ELECTROLYSIS CELL (AD-MEC) INTEGRATED SYSTEMS
Şanlı, Mert; Yılmazel Tokel, Yasemin Dilşad; Department of Environmental Engineering (2022-11-28)
Anaerobic digestion (AD) is a common method used for treatment of complex wastes with additional benefit of biogas production. Yet, the process has several limitations such as slow kinetics, long start-up periods and low methane (CH4) production yield. With the integration of microbial electrolysis cells (MECs) into AD, it is anticipated that these limitations of AD will be reduced. The reasons of such improvements in the AD-MEC integrated systems may stem from the enhanced electron transfer in microbial co...
Effect of added ingredients on the acrylamide level and quality of extrudates
Yavuz, Merve; Şensoy, İlkay; Özçelik, Beraat; Department of Food Engineering (2014)
Ingredients which are NaCl, CaCl2, ascorbic acid, citric acid, glycine, cysteine and quercetin were blended at two different concentrations with whole wheat flour, mixed with D-glucose monohydrate (100:5, w/w), and fed to twin screw extruder. Effect of these ingredients on acrylamide level and quality characteristics of extrudates were investigated. Set zone temperatures were 80 ± 2, 90 ± 2, 115 ± 2 and 150 ± 2 oC with 180 rpm screw speed and feed flow rate of 30 g/min during extrusion. Feed moisture conten...
Effect of high hydrostatic pressure on the profile of proteins extracted from Betula pendula pollens
Altuner, Ergin Murat; Ceter, Talip; Alpas, Hami (2014-10-02)
High hydrostatic pressure (HHP) has high success potential in pollen protein extraction, but its effect on pollen protein profiles has not been studied yet. The aim of this study is to put forward whether HHP processing causes a change in the protein profiles extracted from pollens or not. In this study, proteins extracted from Betula pendula pollens were studied at 100, 200 and 300 MPa at room temperature for 5 min. In addition, the efficiency of three different extraction solvents, namely phosphate buffer...
