Textural properties in density-separated coal fractions

Properties of alkaline-phosphatase fractions separated by starch-gel electrophoresis.

Sensitizing Capacity When Separated into Fractions

The major peanut allergen Ara h 1 is an easily digestible protein under physiological conditions. The present study revealed that pepsin digestion products of Ara h 1 retained the sensitizing potential in a Brown Norway rat model, while this sensitizing capacity was lost by separating the digest into fractions by gel permeation chromatography. Protein chemical analysis showed that the peptide c...

The effect of the textural properties of bituminous coal chars on NO emissions

NO is the primary product of the oxidation of char nitrogen, and in some combustion processes the NO can be reduced on the char surface to give N2O and/or N2. In this study a range of bituminous coals (low, medium and high volatile matter content) were pyrolysed in a fixed bed reactor at various heating rates. Textural characterisation was carried out by measuring true (He) and apparent (Hg) de...

Textural Properties of Sorghum Dough

Chemical analysis Textural properties of dough prepared from the flours of eight sorghum cultivars were evaluated subjectively and also measured using a back-extrusion cell in an Ins&on Food Testing Instrument. The force and energy required for the extrusion of good quality cohesive dough were high. A poor quality dough was compressed into the cell without extrusion. The influence of flour-wate...

Spectroscopic and conformational properties of size-fractions separated from a lignite humic acid.

A lignite humic acid (HA) was fractionated by preparative high performance size-exclusion chromatography (HPSEC) in seven different size-fractions. The size-fractions were characterized by cross polarization (CP) magic angle spinning (MAS) (13)C NMR spectroscopy and a further analytical HPSEC elution under UV and fluorescence detection. The alkyl hydrophobic components mainly distributed in the...
