“…This second stage began between 200 and 210 °C for the other samples. Different thermal decomposition stages observed for lignin with TGAs are in accordance with other literature reports (Domínguez et al 2008;González et al 2009;Ibrahim et al 2011;Hussin et al 2014).…”

“…Except for the precipitated lignin obtained with phosphoric acid at pH 2 (which apparently had a higher level of contamination with hemicelluloses), all the IR spectra were very similar to one another, which suggested that the general compositions of the precipitated soda lignins were not affected by the acids used or their concentration levels. All of these assignments are based on literature reports (Ibrahim et al 2004;Tejado et al 2007;González et al 2009;Minu et al 2012;Hussin et al 2014;Alekhina et al 2015). Fig.…”

“…More recently, lignins isolated from oil palm fronds were found to limit the oxidation of methyl linoleate induced by 2,2′-azobis(isobutyronitrile). 46 In the current study, the capacity of grass lignins to prevent lipid oxidation was assessed through the capacity of their ethanolsoluble fractions to prevent oxidation of linoleic acid dispersed in an aqueous phase, using 2,2′-azobis(2-amidinopropane) dihydrochloride (AAPH) as oxidation initiator. This system was selected as representative of an emulsified matrix in cosmetic or food products.…”

The antioxidant properties of grass lignins recovered from an alkaline industrial process and from different ethanol organosolv pretreatment processes were compared using two types of tests: (i) classical radical 2,2'-diphenyl-1-picrylhydrazyl (DPPH(•)) scavenging tests in dioxane/water or ethanol and (ii) tests involving multiphasic systems (lipid dispersion in water or cellulose film suspended in ethanol). These multiphasic systems were representative of food and packaging matrices in view of high-value applications. All lignins, in solution or in the film, effectively scavenged radicals. Moreover, they were competitive with a food commercial rosemary extract to protect linoleic acid against oxidation. Whereas the DPPH(•) test in dioxane was not discriminant, differences appeared between lignins when the test was performed in ethanol or with the multiphasic systems. Moreover, radical scavenging activity was preserved in the film even after its immersion in ethanol. Structural analysis of lignins revealed that low-molar-mass phenolics, namely p-hydroxycinnamic acids and lignin depolymerization products, governed lignin antioxidant properties in the multiphasic systems.

“…Lignins with lower molecular weights, such as L2, L3, and L4, are preferred for phenolformaldehyde resin due to higher reactivity than lignins with high molecular weight (Mansouri and Salvadó 2006). Moreover, lignins with lower molecular weights can be utilized in other applications like antioxidants, adhesives, and paints (Hussin et al 2014). Lignins with high molecular weight show poor antioxidant activity (El Hage et al 2012).…”

The physico-chemical properties of lignin isolated from lignocellulosic bioethanol residues and hardwood kraft black liquor were compared with two commercial lignins, kraft softwood lignin, and soda non-wood lignin. Lignin from the industrial residues was isolated through the acid precipitation method. The amount of lignin isolated was approximately 38% of the dry weight of lignocellulosic bioethanol residues and approximately 27% of the black liquor solids. The numbers of methoxyl groups and phenolic and aliphatic hydroxyls were determined to derive a molecular formula for each of the four lignins. The molecular weights of the lignins were measured by high performance size exclusion chromatography. Potential value-added applications of the lignins were summarized based on their molecular weights and physico-chemical characteristics.
