“…The values in Da of the structures corresponding to these peaks must be subtracted of 23 Da to obtain the value of their molecular weight from the peaks of the MALDI spectrum due to the NaCl matrix enhancer used. During the formation of oligomers, the loss of either a hydrogen atom or the protonated form [17] and the loss of a hydroxyl group [18] of the monomer units must be taken into account if they are not the terminal units of the oligomers. The losed of the water molecules must be taken into consideration, since water molecule will be eliminated (1 water molecule for every 2 monomers) from the oligomer during the condensation.…”

“…The losed of the water molecules must be taken into consideration, since water molecule will be eliminated (1 water molecule for every 2 monomers) from the oligomer during the condensation. The spectra of each lignin grasses revealed the presence Protonated or multiprotonated (with Na + ) oligomers and there are some oligomers which have lost or acquired an OH group [17] ( Table 2 and Table 3). There are some signals in the range of 482-700 Da confirming the presence of trimers S-βO4-H-β5-G, G-βO4-G-β5-G and S-βO4-S-ββ-S.…”

In order to manufacture environmentally friendly particle boards and enhance local resources, the lignins of Sorghum bicolor and Andropogon gayanus characterized using RMN 13 C and MALDI TOF have the same structures. They contents Guaiacyl (G), Syringyl (S), p-hydroxyphenylpropane (H) and functional groups of phenols, flavonoids and secondary alcohols. The total phenol content determinated using Folin-Ciocalteu reagent is respectively 20.97 and 15.42 mg eqgallic acid/g of extract. The power of their adhesives is different. The Internal Bond (IB) of particleboards manufactured with these adhesives are respectively 0.37 MPa and 0.41 MPa. These lignins can be used as antioxydants.

“…However, the present use of commercial tannins for leather manufacturing [122], and beverages [123] limits their availability for other industrial resins. Despite this, tannins have been the subject of extensive research, leading to the exploration of a wide range of adhesive applications [14,101,124].…”

Today's society relies heavily on glued wood products for constructions, furniture, and floorings, for example. Essentially, all adhesives on the market are based on fossil-based resources, and many also contain formaldehyde to yield sufficient reactivity and adhesive performance. Formaldehyde is soon to be banned from consumer goods in Europe, due to its carcinogenic and allergenic features. With the rapidly growing societal environmental awareness, it becomes evident that it is crucial to seek greener, more sustainable alternatives. There is nothing new to this idea; on the contrary, prior to the advent of synthetic polymers, a range of biopolymers such as proteins and starch, were successfully used. However, since adhesives based on synthetic polymers were found to perform better, especially regarding the water resistance, the naturally sourced adhesives have had a subordinate role up until recently. The growing interest for using bio-polymers from renewable resources, such as wood/forest, corn, and cereals have spurred significant R&D developments toward the use of bio-polymers in green wood adhesives. The scope of the present chapter is to summarize, in short, some of the most recent scientific literature regarding the development of green adhesives.
