Rapid and accurate determination of the lignin content of lignocellulosic biomass by solid-state NMR.
Biofuels and biomaterials, produced from lignocellulosic feedstock, require facile access to cellulose and hemicellulose to be competitive with petroleum processing and sugar-based fermentation. Physical-chemical barriers resulting from lignin complicates the hydrolysis biomass into fermentable sugars. Thus, the amount of lignin within a substrate is critical in determining biomass processing. ...
متن کاملRNA structure determination by solid-state NMR spectroscopy
Knowledge of the RNA three-dimensional structure, either in isolation or as part of RNP complexes, is fundamental to understand the mechanism of numerous cellular processes. Because of its flexibility, RNA represents a challenge for crystallization, while the large size of cellular complexes brings solution-state NMR to its limits. Here, we demonstrate an alternative approach on the basis of so...
متن کاملDetermination of fat content in foods by analytical SFE
Analytical supercritical fluid extraction (WE) is finding widespread application in the analysis of foodstuffs, agriculturally derived materials, and natural products. The high efficacy that SE demonstrates toward the removal of oils and fats from such matrices makes it a natural technique for the determination of their fat and oil content. In this review, we have highlighted what is essential ...
متن کاملAutomated Determination of Total Fat, Saturated Fat, Monounsaturated Fat and Trans Fat Content in Food Samples
Determination of total fat, saturated fat, monounsaturated fat and trans fat content in food samples is necessary for complying with applicable food labeling requirements. A typical procedure for saponifi cation of the sample involves refl uxing with sodium methoxide in methanol, followed by a second refl ux with boron trifl uoride in order to esterify the free fatty acids. Prior to injection i...
