Degradation5

Sugars2
  • This is achieved with fire that lightly toasts the face of the wood, beginning the process of turning the hemicellulose into sugars. (tastingtable.com)
  • In order to access the sugars to make biofuel, the fibrous lignin must be broken apart. (hudsonalpha.org)
Biomass2
  • Moreover, monitoring and optimization of biomass processing based on chemical changes of the hemicellulose fraction is possible. (boku.ac.at)
  • However, the wide range of molecules present in SCG such as saccharides, lignin, lipids and proteins give this biomass source a large chemical functionality. (bath.ac.uk)
Pulp2
  • Semichemical pulp is made by treating wood chips with sulfite or alkali in amounts and under conditions that soften the lignin but dissolve only part of it. (britannica.com)
  • Meanwhile over half the plants' fibre pulp consists of hemicellulose and lignin. (lu.se)
Consists3
Aromatic2
  • Significant progress is being made, and methods for deconstructing lignin are producing good yields of small, mononuclear aromatic products-sufficient amounts to enable studies of the potential use of these compounds as replacements for compounds currently produced from petroleum. (acs.org)
  • To investigate the use of lignin products in epoxies, we begin with aromatic acids that can be produced from lignin, treat them with epichlorohydrin to make glycidyl ethers, and investigate the thermal and mechanical properties of cured mixtures of these compounds with a commercial epoxy resin (EPON 826) and an anhydride curing agent (NMA). (acs.org)
Oligosaccharides1
  • Australia and New Zealand's food regulator FSANZ says: "dietary fibre means that fraction of the edible part of plants or their extracts, or synthetic analogues that are resistant to the digestion and absorption in the small intestine, usually with complete or partial fermentation in the large intestine … and includes polysaccharides, oligosaccharides and lignins. (glycemicindex.com)

Molecules4
  • Much effort has been invested in developing methods for producing small molecules from lignin as a way to source feedstock chemicals from renewable sources. (acs.org)
  • The use of lignin-derived small molecules in high-value systems such as epoxies may help improve the economics of biorefineries. (acs.org)
  • The walls of plant cells are made up of three molecules: cellulose, hemicellulose, and lignin. (hudsonalpha.org)
  • However, the lignin is a fibrous molecule that binds all of the molecules together in a compact structure, giving the plant the structural support needed to survive. (hudsonalpha.org)
