Extraction, Fractionation, and Chemical Characterisation of Fucoidans from the Brown Seaweed Sargassum pallidum
brown seaweed Sargassum pallidum fucoidan extraction cytotoxic activity
2016/12/9
The fucoidans were obtained by extraction with water and gradient precipitation with different concentrations of ethanol. The main structural characterisations and bioactivities were achieved. Four fr...
Efficiency of size-dependent particle separation by pinched flow fractionation
Particle separation Pinchedtionation Fluid Dynamics
2012/4/24
Pinched flow fractionation is shown to be an efficient and selective way to quickly separate particles by size in a very polydisperse semi-concentrated suspension. In an effort to optimize the method,...
Influence of the environmental conditions on the fractionation of heavy metals in the Fenhe reservoir sediment
reservoir sediment-water interface heavy metal fractionation environmental conditions
2017/8/9
The BCR sequential extraction and EDTA single extraction method were applied to study the fractionation, concentration and bioaccessibility of the heavy metals in the sediment of Fenhe reservoir in No...
FRACTIONATION AND CHARACTERISATION OF TECHNICAL AMMONIUM LIGNOSULPHONATE
FRACTIONATION CHARACTERISATION TECHNICAL AMMONIUM LIGNOSULPHONATE
2010/10/25
It is difficult to use lignin in any analytical methodology without reducing its considerable polydispersity by fractionation. An ammonium lignosulphonate sample was fractionated using a method of par...
基于钙离子诱导的大豆蛋白分级技术（Fractionation of Soybean Proteins Based on Technique of Ca2+ Induced-precipitation）
大豆蛋白 分级 氯化钙 功能性质
2009/11/24
通过低温下添加不同浓度钙离子和还原剂亚硫酸氢钠以及pH值的控制，对大豆蛋白中两种主要组分7S蛋白和11S蛋白进行两步法诱导分级分离并优化条件，制备出含11S蛋白57.4%的分级大豆蛋白Ⅰ和含7S大豆蛋白61.4%的分级大豆蛋白Ⅱ。功能性质评价结果表明，分级大豆蛋白Ⅰ比大豆分离蛋白具有更好的凝胶性和起泡性，而分级大豆蛋白Ⅱ比大豆分离蛋白具有更好的乳化性，说明钙离子的诱导分级技术可以应用于食品工业来更...
Mathematical Modeling of Fractionation During the Mold Filling of Semi-Solid Metal Slurries
Semi-solid slurries fractionation mold filling mathematical modeling
2009/10/14
Mold filling and fractionation of semi-solid slurries are numerically investigated. A tin lead alloy (Sn-15%Pb) is employed to fill the mold under a range of processing conditions including inflow vel...
