“…Today soybeans are considered to be the world's most important oilseed crop, accounting for 58% of total oilseed production worldwide in 2010 (American Soybean Association, 2011). Soy oil is used not only for food purposes but also for a range of products in industry (Schmitz et al, 2008).…”

New Mutations in a Delta‐9‐Stearoyl‐Acyl Carrier Protein Desaturase Gene Associated with Enhanced Stearic Acid Levels in Soybean Seed

et al. 2012

Soybean [Glycine max (L.) Men.] oil from conventional cultivars typically contains -30 g kg-'' stearic acid of the total seed oil. Increased stearic acid concentration in the seed oil of soybeans is desirable for certain food and industrial uses. To date a small number of mutants have been developed with increased stearic acid levels three to six times that of normal. At least two such lines were found to possess separate mutations in the delta-9-stearoyl-acyl carrier protein desaturase C gene {SACPD-C) that dramatically increased seed stearic acid concentration. We now report additional independent mutations in this gene that increase seed stearic acid levels of the soybean germplasm line RG7 to -116 g kg"''. An Fg recombinant inbred line (RIL) population was developed to determine the relationship between the RG7 SACPD-C mutation and stearic acid concentration. Transgressive segregation in the progeny of the cross between mutant lines RG7 and RG2 (low palmitic acid) further increases seed stearic acid to almost 180 g kg-^, suggesting the presence of yet another gene having a significant effect on stearic acid accumulation. We also discerned an independent, presumably allelic, mutation within the SACPD-C gene in line RG8, which has about 106 g kg '' stearic acid. Molecular markers diagnostic for the RG7 and RG8 SACPD-C mutations were developed, enabling rapid selection for these mutations in the development of cultivars with increased seed stearic acid content in the seed oil.

“…There has been continuous research and development concerning the viability of wood-based panels such as particleboards, MDF, and OSB with the introduction of natural fibers as direct or partial substitute of wood particles in its production. 75 Table 1 tabulated some of the common agricultural wastes used for particleboards. Pan et al 49 made rice straw particleboard by replacing polymeric methylene diphenyl diisocyanate (PMDI) with rice bran adhesive up to 30% of PMDI because of the highly expensive nature and toxicity of PMDI, achieving final boards with properties like those of 100% PMDI bonded particleboard.…”

Impending health challenges in the formulations of particleboards from cellulosic-based waste particles such as wood chips, sawdust, and veneer boards are of great concern. These wastes are majorly bonded together with synthetic resin or binder in the presence of heat and pressure to produce particleboards of various specifications and sizes depending on the end-use. The qualities of the particleboards depend on the modification of the particle geometry, resin levels, board density, and manufacturing processes. The addition of special additives to enhance the qualitative performance of particleboards such as dimensional stability, fire retardancy enhancement, and moisture resistance is included in the manufacturing process. The milestone in the use of wood particles for particleboard manufacture is the large reduction in the environmental hazard that these abundant wastes cause. Furthermore, this review reports recent research efforts in the use of green adhesives to reduce the health threat related to utilizing formaldehyde-based particleboard. The use of adhesives produced from natural sources has contributed toward the reduction in the impending health challenges and the cost of building construction by using such a particleboard.

“…Some soybean-based commercial adhesives include the use of crosslinking resins such as cationic polyamidoamine-epichlorohydrin (PAE) resins [39]. The blending of soy protein with other synthetic materials and other proteins has been reported to produce adhesives with better performance than current adhesives; some cases include blends with blood, casein, phenol formaldehyde (PF) and phenol-resorcinol-formaldehyde (PRF), polyvinyl alcohol and polyvinyl acetate [6]. However, some of the proposed approaches still use formaldehyde or similar chemicals to crosslink the proteins.…”

Tuning the Adhesive Properties of Soy Protein Wood Adhesives with Different Coadjutant Polymers, Nanocellulose and Lignin

et al. 2021

Commercial wood adhesives are based on products that contain formaldehyde; however, environmental and health concerns about formaldehyde emissions from wood products have influenced research and development efforts in order to find alternative, formaldehyde-free products for wood adhesives. In this work, different soy protein-based wood adhesives are proposed, and their performance is compared to commercial urea formaldehyde (UF) adhesive. Soy protein-based wood adhesives were prepared using either soy protein isolate (SPI) or soy protein flour (SF) with different coadjutant polymers: polyethylene oxide (PEO), hydroxypropyl methylcellulose (HPMC), cellulose nanofibrils (CNF) or polyvinyl alcohol (PVA) with and without addition of kraft lignin. The effects of the type of soy protein, solids content, coadjutant polymer and lignin addition were investigated. The wood adhesive formulations were tested on the bonding of hardwood (white maple) and softwood (southern yellow pine) and the dry shear strength of test specimens was measured according to method ASTM D905-08. The adhesive formulations with SPI achieved significantly higher values than those with SF. The dry shear strength of the adhesives varies depending on the coadjutant polymer, the wood species and the addition of lignin.
