“…impurity) in protein fractions CSPw, CSPa, and CSPI. The contents of ADF, NDF, and ADL were all higher in the pilot-scale produced WCSM and CSIR than the two fractions from laboratory experiments (He et al, 2015) apparently due to the higher fiber content in the mill-produced staring material CSM. Those data also revealed that there were 17.6% and 8.4% of WCSM, and 24.6% and 10.2% of CSIR, respectively, as cellulose and hemicelluloses.…”

“…The protein content of CSPw was 64.4% which was lower than the protein content of laboratory-made CSPw (He et al, 2013a;He et al, 2015). The product CSPa was basically protein-dominated, more like the total protein isolate CSPI, which is also observed with the laboratory-made CSPa and CSPI (He et al, 2013a;He et al, 2015). Oil was an impurity (2.5%) in the staring material CSM (Table 1).…”

“…Acid detergent fiber (ADF), neutral detergent fiber (NDF) and acid detergent lignin (ADL) were determined using the filter bag methods with an Ankom Fiber Analyzer (Ankom Technology, Macedon, NY) (He et al, 2014f). Contents of cellulose and hemicellulose were calculated per the differences between ADF and ADL, and that between NDF and ADF, respectively (He et al, 2015;Wolfrum et al, 2009). Total oil content was determined using Soxhlet extraction with the Tecator Soxtec System HT 1043 (Foss, Eden Prairie, MN, USA) using boiling and condensing temperatures of 110 o C and 15 o C, respectively (Cao et al, 2013).…”

Enhanced utilization of defatted cottonseed meal (CSM)-based products as biobased raw materials would increase the profitability of cotton growers and processors. In this work, a multiple-step procedure that can be used to produce water washed cottonseed meal (WCSM) and a co-product water soluble cottonseed protein (CSPw) from CSM was tested at pilot scale. Alternatively, the procedure can also be used to produce CSPw, alkali soluble protein (CSPa) and the protein extracted insoluble residue (CSIR). The chemical composition of these pilot-produced products was generally comparable to that of the corresponding laboratory-prepared products. The fiber content was higher in the pilot-produced WCSM than in laboratory-produced product mainly due to the higher fiber content in the mill-based starting meal material used in the pilot trial. The protein content in the pilot-produced CSPw was only 64.4% of the solid matter, indicating that additional rinse is needed before drying the HCl-precipitated CSPw fraction. Per the yield and composition data, it was concluded that it was feasible to produce the four products WCSM, CSPw, CSPa, and CSIR from CSM in a large scale. Thus, adoption of this procedure would provide the necessary quantities for exploring the practical utilization of these products in biomaterial industry.

“…Previous characterization of cottonseed meal products were mainly on the chemical composition (Berardi and Cherry, 1979;He et al, 2015;Zhang et al, 2009), protein structure (He et al, 2013a;2014c;King, 1980), and physicochemical properties (Grevellec et al, 2001;He et al, 2016b;Tunc and Duman, 2007;Zhou et al, 2015). Unlike several agricultural products noted above, the surface characteristics of cottonseed meal products have not been examined so far.…”

The utilization of cottonseed meal products as valuable industrial materials needs to be exploited. We have recently produced water-washed cottonseed meal, total cottonseed protein, sequentially extracted water-and alkali-soluble proteins, and two residues after the total and sequential protein extractions at a pilot scale. In this work, the surface characteristics of the six cottonseed meal products were examined by scanning electron microscopy (SEM), scanning electron microscopy-energy dispersive spectrometer (SEM-EDS), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results showed that the surface properties of the six products differed from those of a commercial soy protein flour examined comparatively in this work. The compact morphology and relative-high N composition were observed in all three protein products, with greater similarity between the total protein and alkali-soluble protein. The surfaces of the two residue products were more porous with polysaccharide features. Washed cottonseed meal possessed the surface features similar to those of the residues. In the meantime, the N-associated functional groups were under-represented in the surfaces of all samples, compared to their bulk composition. Information derived from this work increased the understanding of the surface functional properties of cottonseed meal products, which would benefit their practical utilization.

Glanded (Gd) cottonseed (Gossypium hirsutum L.) contains scattered gossypol glands. Glandless (Gl) cottonseed is a new type of seed containing only trace levels of gossypol. This work quantitatively compared the content and migration pattern of Gd and Gl protein isolates. Both protein samples were subjected to sodium dodecyl sulfate (SDS)-gel electrophoresis, and the protein gel bands were separated into seven partitions for peptide mass spectroscopic analysis. While multiple peptide fragments (isoformers) of vicilin and legumin proteins were present in both samples, the percentage of vicilins in total seed protein was higher in Gd (74.9%) than in Gl (63.4%). In contrast, legumin proteins were more abundant in Gl (30.4%) than Gd (23.6%).Minor protein components such as lipid-related oleosins and vicilin-like antimicrobial peptides 2-2 were also observed at a relatively higher incidence in Gl compared with Gd, potentially reflecting a need for increased protein-related defense capability in the absence of gossypol against natural predators or adverse growth environment.
