(Elsevier, 2012-01)The effect of high hydrostatic pressure application on fetal bovine serum components and the model microorganism (Bovine Viral Diarrheavirus type 1 NADL strain) was studied at 132 and 220MPa pressure for 5min at 25°C. ... -
Biophysical evaluation of physiological effects of gilthead sea bream (Sparus aurata) farming using FTIR spectroscopy
(Elsevier, 2014)Sparus aurata is one of the two most important cultured fish species in the Mediterranean region. The present work investigates the effects of culturing in S. aurata liver tissue at the molecular level using Fourier Transform ... -
Capsaicin emulsions: Formulation and characterization
(Taylor & Francis, 2017-08)Oleoresin capsicum, the oil extract of chili pepper, is mainly composed of capsaicin. Capsaicin is a hydrophobic volatile compound exhibiting antimicrobial activity against various microorganisms. Capsaicin in the form of ... -
Characterization and classification of Turkish wines based on elemental composition
(American Society for Enology and Viticulture, 2014-03)Commercial wines from 13 native and nonnative varieties in Turkey were analyzed for their elemental composition. Wines from four vintages (2006-2009) were analyzed by inductively coupled plasma with atomic emission ... -
Characterization of silk fibroin based films loaded with rutin-β-cyclodextrin inclusion complexes
(Springer, 2014-10)In this study, cyclodextrin inclusion complexes with rutin were prepared via co-precipitation method. Stability constant and solubility energy of beta-cyclodextrin complex were calculated as 262 M-1 and 1,737 kJ mol-1, ... -
