“…This result implied that the hemicelluloses obtained by the higher concentration of alkali appeared to be more linear. This observation was due to the fact that the chains of the unsubstituted hemicelluloses were prone to forming strong hydrogen bonds, causing inter-chain aggregation, and increased difficulty in the isolation process, and thus a higher concentration of alkali was needed (Hoije et al 2005). The residue left after the sequential extraction contained mainly glucose (81.2%), and arabinose (17.6%) as shown by sugar composition analysis in Table 2.…”

Six hemicellulosic samples were isolated from cell wall material of dewaxed sweet sorghum (Sorghum bicolor (L.) Moench) leaves by sequential extractions with distilled water, alkali, and organic alkali solvent. The samples were treated with water, 1% NaOH, and 60% ethanol. The organic alkali samples were treated with 1%, 3%, 5%, and 8% NaOH, which yielded 8.3%, 5.4%, 1.0%, 5.6%, 2.5%, and 4.9% hemicelluloses based on the dry initial sweet sorghum leaves, respectively, and resulted in a total release of 81% of all hemicelluloses originally present in the cell wall. The results indicated that water-soluble hemicelluloses contained noticeable amounts of glucose, arabinose, galactose, and xylose, and had a relatively lower molecular weight (17300 g/mol). The four alkali-soluble hemicellulosic fractions, rich in xylose, were more linear, and had higher molecular weights (48500-128000 g/mol) than those of the alkali organic-soluble hemicellulosic fraction. With an increase of NaOH concentration from 1% to 8%, the ratio of arabinose to xylose decreased from 0.29 to 0.01, which implied that the hemicelluloses obtained by the higher concentration of alkali appeared to be more linear. Based on the sugar analysis, Fourier transform infrared (FT-IR), and nuclear magnetic resonance (NMR) results, 4-O-methylglucuronoarabinoxylans were the major constituents of the hemicellulosic polymers.

“…Additionally, corrosion caused by severe acid treatments increase the equipment costs. AXs yield obtained with chemical methods is between 26% and 57% (Aguedo et al, 2014;Höije et al, 2005;Hollmann & Lindhauer, 2005). Enzymatic extractions are green processes and they get good extraction yields (17-91%) (Aguedo et al, 2014;Höije et al, 2005;Maes & Delcour, 2002).…”

The extraction/hydrolysis process of arabinoxylans from destarched wheat bran was studied in this work using different mesoporous silica supports and the corresponding RuCl3-based catalysts. The effects of temperature, time, catalyst supports and ruthenium catalysts were investigated and discussed in terms of the arabinoxylans extraction yield and their polymerization degree. Relatively high temperatures (180 ºC), short extraction times (10 minutes) and RuCl3 supported on Al-MCM-48 led to a high amount of arabinoxylans extracted (78%) with a low molecular weight (9 KDa). Finally, a relation between the operating conditions, the arabinoxylans extraction yield and the molecular weight was stablished based on the obtained results.

“…An increasing number of studies have investigated the use of hemicelluloses as sustainable packaging material, as pointed out in reviews by Hansen and Plackett (2008) and . Film formation from agro-based xylans, such as those from cotton stalks, barley husks, oat spelt, corn hulls, and wheat bran, has been studied lately (Zhang and Whistler 2004;Höije et al 2005;Mikkonen et al 2009;Zhang et al 2011;Bahcegul et al 2012). GGM film formation has been studied with plasticizers, with reinforcement using nano-sized cellulose, and with cross-linking agents (Hartman et al 2006, Mikkonen et al 2010.…”

aOat spelt arabinoxylan (OsAX) and spruce galactoglucomannan (GGM) are hemicelluloses that can be extracted in large quantities from sidestreams of the agriculture and forest industries. They both form selfstanding films, making them potential future packaging materials. This systematic study focuses on the effect of long-term storage on the physical stability of hemicellulose-based films. OsAX and GGM films were plasticized with 40% (w/w of the polysaccharide) of glycerol, sorbitol, or their blends, and their stability was followed for four months. Ageing especially affected the glycerol-containing films, in which the tensile strength and Young's modulus increased and elongation at break decreased. Although the mechanical properties were altered, storage did not affect crystallinity of the films. Oxygen gas permeability (OP) and water vapor permeability (WVP) properties were monitored in OsAX films. Interestingly WVP decreased during storage; more than a 40% decrease was seen when plasticizer blends contained 50% or more glycerol. In contrast, there were no drastic changes in the OP during storage; all the OPs obtained were between 3.7 and 8.9 [cm 3 µm/ (m 2 d kPa)].
