Optimization of Ultrasound Assisted Extraction of Bioactive Compounds from Apple Pomace
(MDPI, 2021-06-22)
In the present work, the optimization of the extraction of antioxidant compounds from apple pomace using ultrasound technology as an environmentally friendly and intensification process was developed. Different sonication ...
Effect of different hemicelluloses characteristics on film forming properties
(Elsevier, 2013)
Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources ...
Effect of alkaline and autohydrolysis processes on the purity of obtained hemicelluloses from corn stalks
(Elsevier, 2012)
[EN]A study of the potential of autohydrolysis and alkaline extraction processes from corn stalks was performed
for high purity hemicellulose extraction. The influence of process parameters on the purity of
obtained ...
Fermentable sugars recovery from grape stalks for bioethanol production
(Elsevier, 2013-07-02)
[EN]Three different processes were investigated for the recovery of fermentable sugars from grape stalks:
autohydrolysis at 121 ºC before and after a pre-washing step and acid hydrolysis (2% H2SO4 w/w) after a
pre-washing ...
Corncob arabinoxylan for new materials
(Elsevier, 2014-02)
[EN]tCorncob agricultural waste was used as a source of arabinoxylan for preparation of films. Three ara-binoxylan samples were prepared: crude extract (CCAX), purified by a washing step, and purified bybleaching CCAX. ...
Liquefaction of Kraft Lignin at Atmospheric Pressure
(Tech Science Press, 2019)
[EN]Kraft lignin was liquefied using polyethylene glycol #400 (PEG) and
glycerol (G) in a weight ratio of 80/20 (w/w) and sulphuric acid (SA) as catalyst
under atmospheric pressure at 160ºC. The three independent variables: ...
Lignin-ester derivatives as novel thermoplastic materials
(RSC, 2016)
[EN] Spruce and eucalyptus lignins isolated by an organosolv process and lauroyl chloride were used as raw material for the synthesis of lignin-ester derivatives. The obtained products presented new and interesting properties ...
Modification of Eucalyptus and Spruce organosolv lignins with fatty acids to use as filler in PLA
(2016-05-09)
Spruce (softwood) and Eucalyptus (hardwood) woods were used as raw material for lignin extraction by
organosolv process. Chemical, structural and thermal characterizations of the extracted lignin samples have
been performed ...
Liquefaction of Kraft lignin using polyhydric alcohols and organic acids as catalysts for sustainable polyols production
(Elsevier, 2019)
[EN]In this work, three different organic acid catalysts, (acetic acid, lactic acid and citric acid), are proposed as an
alternative to common catalysts used in the liquefaction process of Kraft lignin. These organic acids ...
