“…Evaluations of Nebraska-grown hybrid hazelnuts suggest that a significant opportunity exists for economical development of hybrid hazelnuts as a sustainable and environmentally friendly oilseed crop for food, feed and industrial applications (Xu et al, 2007;Xu & Hanna, 2009, 2010a,b, 2011.

The hard shell of a hazelnut is a major waste of the hazelnut industry. The chemical composition, phenolic compounds (total phenolics, tannins and condensed tannins), antioxidant activity (DPPH and ABTS freeradical scavenging assays), and the relationships between phenolic compounds and antioxidant activities of the hazelnut shells from twelve US grown cultivars were investigated to for potential commercial development. Crude fibre accounted for over 85% of total carbohydrate. The shells contained high concentrations of phenolic compounds. Concentrations of phenolic constituents and ABTS •+ -scavenging capacities were significantly higher (P > 0.05) in the Oregon cultivars than their Nebraska counterparts. There were significant positive correlations between ABTS •+ scavenging capacities and the phenolic compounds, whereas DPPH • -scavenging capacity demonstrated a weak negative correlation with ABTS •+ scavenging capacity and the phenolics. The results suggest that hazelnut hard shell may serve as a potential source of natural antioxidants for food applications.

“…After analyzing the composition of authentic hazelnut oils obtained from nuts collected from five countries, Crews et al (2005) found that the oleic acid content varied between 75.3 and 83.8%, linoleic was in the 6.2-15.9% range, palmitic ranged from 5.0 to 6.6% and stearic varied between 1.6 to 2.9%. Owing to the high oil content, hazel kernels could be used as raw material in biodiesel production (Xu and Hanna, 2009). Three decades ago, the Turkish hazel genotype selection program, using natural populations and trees of secondary origin, started in Serbia.…”

Five genotypes of Turkish hazelnuts (Corylus colurna L.) were analyzed for chemical composition, including total oil content, fatty acid and sterol composition. The oil yields from these kernels varied from 36.5% to 60.8% and the main fatty acids were oleic acid (79.34-83.0%) and linoleic acid (7.52-10.81%). The polyunsaturated/saturated fatty acid ratio was low, ranging from 0.87 to 1.25. Total phytosterol content ranged from 4.52 to 6.50 mg g -1 of oil. Among the eleven sterols identified and quantified, β-sitosterol was the major one with a mean percentage of 65.09% while fucosterol and campesterol were the second and the third components of the group with mean values of 10.91% and 4.36%, respectively. The radical scavenging activity was evaluated using 2.2-diphenyl-1 picrylhydrazyl (DPPH) assay.

“…Soymeal is readily available in large quantities with annual production of around 172 million metric tons, low cost ($0.18-0.25 per lb) and good biodegradability as a coproduct from edible oil and bio-diesel production (Xu and Hanna 2009;Robert et al, 2014). Soymeal has been used as fillers or extenders of plastics (Wang et al, 1996), plywood bonding agent (Kumar et al, 2002), additives or coating of paper (Selling et al, 2013;Arboleda et al, 2014;Salam et al, 2015) and protein-based composites (Matthews et al, 2011;Khansari et al, 2013;Rahman et al, 2014) or scaffolds for tissue engineering (Huang et al, 2012;Zhao et al, 2014).…”

a b s t r a c tSoymeal, which contains natural plasticizer and tackifier, has been used to fabricate biodegradable and low-cost warp sizes, with potential for replacing non-biodegradable polyvinyl alcohol (PVA) sizes for large-quantity industrial applications. Warp sizes from soyprotein isolates (SPI) have been reported as a potential substitute for PVA sizes, which contribute to high chemical oxygen demand in textile effluents and cause serious water pollution. However, sizes from SPI are high in cost and need additional plasticizers to overcome brittleness of films. In this research, the developed low-cost soymeal sizes contain soyprotein as majority and saccharides/saponified-oil from soymeal as minorities. Comparing to films from triethanolamine-plasticized SPI sizes, the soymeal size had about 30.1, 25.2 and 8.3% higher film flexibility, adhesion to yarns and abrasion resistance, respectively. Saccharides in soymeal and saponified oil formed during size extraction functioned as plant-based additives with capability of improving adhesion of protein sizing pastes to cotton and/or polyester yarns and increasing elongation of protein-based size films. Successful utilization of soymeal in textile sizing will lead to its large-quantity application, resulting in high value addition to agricultural byproducts and profound impact on soybean industry and textile industry.
