Determination of Fluoride in Antarctic Krill (Euphausia superba) Using Ion Chromatography and its Pretreatments Selection
fluoride in krill fluoride quantification
2015/3/4
A rapid, sensitive and reliable method to quantify fluoride in Antarctic krill has been established. Four different pretreatment methods were used for the extraction of fluoride: double-deionised wate...
Structure and stability of ion induced whey protein aerated gels
foam globular protein microstructure syneresis Turbiscan
2014/2/24
The microstructure and stability of aerated whey protein gels were determined. Foamed whey protein gels were obtained using a novel method applying a simultaneous gelation and aeration process. Whey p...
Simultaneous determination of chloride, bromide and iodide in foodstuffs by low pressure ion-exchange chromatography with visible light detection
LPIEC spectrophotometry halide
2014/2/25
An ion-exchange chromatography method with visible light detection was developed for the simultaneous determination of chloride, bromide, and iodide in foodstuffs. They were separated by means of low ...
Apparent Distribution Coefficients of Glucose and Fructose onto Cation-Exchange Resins in Calcium-Ion Form with Different Divinylbenzene Contents
distribution coefficient chromatography cation-exchange resin
2009/7/8
The apparent distribution coefficients, Kapp, of glucose and fructose onto cation-exchange resins in calcium-ion form with different divinylbenzene (DVB) contents were observed over a wide concentrati...
Ethanol Sensor Using Two Chloride Ion-Selective Polymeric Membrane Electrodes
ethanol chloride ion-selective polymeric membrane electrode plasticizer
2009/7/7
An ethanol sensor using two chloride ion-selective polymeric membrane electrodes (Cl-ISEs) was developed. Two different polymeric membranes were used, one with o-nitro-phenyloctyl ether (NPOE) and the...
Determination of Ethanol in Sake Mash by a Chloride Ion-Selective Electrode
ethanol transfer activity coefficient quaternary ammonium salts sake mash
2009/7/7
A chloride ion-selective solvent polymeric membrane electrode (Cl-ISE) using quaternary ammonium salts for determination of the ethanol concentration during sake fermentation is described. The ethanol...
Enhanced Production of Surfactin by Bacillus subtilis E8 Mutant Obtained by Ion Beam Implantation
Bacillus subtilis surfactin ion beam implantation
2009/6/24
The application of surfactin is hampered by its high production cost. In this study, a high-producing surfactin mutant obtained by ion beam implantation, Bacillus subtilis E8, has been used to produce...
Analysis of Molecular or Ion Mobility in Glassy and Rubbery Foods by Electric and Proton-NMR Measurements
glass transition dielectric relaxation ionic conductivity
2009/6/17
The glass transition temperature Tg for many foods has been determined by thermal analysis such as differential scanning calorimetry (DSC). The thermal analysis, however, does not provide information ...
Properties of Gels Induced by Heat, Protease, Calcium Salt, and Acidulant from Calcium Ion-Aggregated Whey Protein Isolate
aggregation of whey proteins gelation microstructure calcium
2008/3/28
Gelation that was induced by heat, protease, calcium salt, or acidulant from a solution of Ca2+- aggregated whey protein was investigated by analyses of the rheological, textural, and microstructural ...
Determination of the Marker Residue of Albendazole in Cheese by Ion-Pair Liquid Chromatography and Fluorescence Detection
albendazole residues cheese liquid chromatography fluorescence detection
2008/3/28
A liquid chromatographic method is described that allows quantitative determination of the marker residue of albendazole in cheese. Samples were extracted with acetonitrile, and the extracts were defa...
