“…Indeed, the high P, K and Mg in WCSM was evidence of the presence of O-rich K and Mg phytate (inositol) (He et al, 2006;2013b). These phytate compounds might have interacted with protein components in WCSM richened in the surface region (Han, 1988;Luna-Valdez et al, 2017). It was noteworthy that N, a representative protein component, did not appear in the EDS spectrograms of these protein samples, which was consistent with the earlier obversation with WCSM samples with different particle sizes (He et al, 2017a).…”

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.

“…However, the contents of the divalent metals were lower in the three protein products CSPw, CSPa, and CSPI than CSM. These data indicated that these minerals in the meal and its products should be mainly present in the forms of K phytate (potassium inositol hexakisphosphate) bonding with P (i. e. K 12 C 6 H 6 O 24 P 6 ), with the secondary highest contributions of Mg and Ca phytate (Mg 6 C 6 H 6 O 24 P 6 and Ca 6 C 6 H 6 O 24 P 6 ) (Han, 1988;He et al, 2006He et al, , 2013c. The content of Na was lower in water washed product WCSM and CSPw, but higher in alkali-relevant CSIR, CSPa, and CSPa, compared to the starting material CSM.…”

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.

“…Higher contents (0.96% and 0.87%) were observed in SPIe and SPIc as some P in phytate was associated with protein (Han, 1988). The contents of K, Na, Ca, and Mg in the four soy meal products were generally at the same levels of SM as these metal contents were low in soy meal and the reagents used in the preparative processes could also introduce minor amounts of these elements into the products.…”

Adhesive bonding of wood plays an increasing role in the forest products industry and is a key factor for efficiently utilizing timber and other lignocellulosic resources. In this work, we obtained five soy meal products through commercial sources or in-house preparations. The protein content was 49.6%, 56.9%, 66.2%, 86.3%, and 91.9% for untreated defatted soy meal, pH 8.5 water washed meal, neutral water washed meal, commercial protein isolate, and in-house prepared protein isolate. The adhesive performances measured by the maximal dry and soaked shear strength of the bonded maple veneers at break were not exactly in the same order of the protein content, indicating that other components (e.g. carbohydrates, metals) might also have played certain roles in the adhesive ability of these products. Data at two press temperatures (i. e. 100, and 130 o C) with or without the addition of tung oil revealed that water washed soy meals behaved more like untreated meal than soy protein isolates. This observation is different from a recent report on the effect of water washing on cottonseed meal products. Thus, further elucidation of the mechanisms or causes of the differing effects of water washing would shed light on the adhesive mechanisms of the two types of oilseed meal materials, thus optimizing use of these materials and their fractions for wood bonding.
