Pericarp Fiber Research Articles

Pyrolysis/gas chromatography/mass spectrometry of spelt (Triticum spelta L.) pericarp

Pyrolysis/gas chromatography/mass spectrometry (PY/GC/MS) was used to characterize the pericarp fiber of grain samples of 6 spelt (Triticum spelta L.) along with 3 different bread wheats plus 7 spelt–wheat crosses. Absolute amounts of lignin and polysaccaride pyrolysis products were quantified as μg mg−1 of sample using an internal standard method. The pyrolysis fragments ascribed to the polysaccharide fraction were significantly more abundant in spelt whereas wheats contained the highest percentage of lignin-derived pyrolysis fragments. Discriminant analysis differentiated spelt, spelt–wheat crosses and wheat. Thus, among possible options for fiber analysis, PY/GC/MS proved to be a reproducible and reliable analytical tool, which can be easily applied to the screening and characterization of cereal fiber. © 1998 John Wiley & Sons, Ltd.

98/02181 Substituting natural gas heating for electric heating: Assessment of the energy and environmental effects in Ontario

Palm oil production is one of the major industries in the south of Thailand. A study of the quantity and potential usage of palm oil mill wastes was carried out. Sixteen palm oil mills in the region generate 386,930 tons/yr 165,830 tons/yr and 110,550 tons/yr of empty fruit bunches, palm press fiber and palm kernel shell, respectively. In addition, 1,202,260 tons/yr of waste water is being treated anaerobically. Only the pericarp fiber is used for boiler feed. Empty fruit bunches and the shell are disposed of by the land filling method, which is very costly. In some factories the empty fruit bunches are burnt in the furnaces, which causes air pollution. The study suggests potential usages of the solid and liquid wastes.
