“…Soy meal was obtained from Kentwood Co-op (Kentwood, LA, USA). The working soy meal was obtained by grinding the meal in a cyclone sample mill (Model 3010–014, UDY Corporation, Fort Collins, CO, USA) to pass a 0.5-mm steel screen [ 26 ].…”

Chemical composition is critical information for product quality and exploration of new use. Hence defatted cottonseed meals from both glanded (with gossypol) and glandless (without gossypol) cotton seeds were separated into water soluble and insoluble fractions, or water soluble, alkali soluble as well as total protein isolates. The contents of gossypol, total protein and amino acids, fiber and carbohydrates, and selected macro and trace elements in these products were determined and compared with each other and with those of soy meal products. Data reported in this work improved our understanding on the chemical composition of different cottonseed meal products that is helpful for more economical utilization of these products. These data would also provide a basic reference for product standards and quality control when the production of the cottonseed meal products comes to pilot and industrial scales.

“…). With this trend, our group has demonstrated that cottonseed meal (CSM)‐based products can be used as wood adhesives . Whereas untreated CSM‐based adhesives showed poor water resistance, water‐washed cottonseed meal (WCSM) and cottonseed protein isolate (CSPI) possess much better water resistance, even better than the more widely studied soy protein isolate (SPI)‐based adhesives …”

To increase the basic knowledge of cottonseed meal (CSM)-based adhesives and optimize the operational parameters for practical applications, in this study, we investigated the effects of pH and storage time on the adhesive performance, water resistance, and rheological properties of CSM, water-washed cottonseed meal (WCSM), and cottonseed protein isolate (CSPI). We found all products possessed the highest dry, wet, and soaked adhesive strengths with the adhesive slurries prepared at pH 6.0. The effects of pH were smaller on WCSM than on CSM and CSPI slurries. Storage time (up to 8 days) did not greatly impact the adhesive performance of WCSM slurries prepared at pH 6.0, 7.5, and 9.0, but slightly reduced the adhesive strength of CSPI slurries with the same pH. The viscosity of WCSM slurries increased with storage over 8 days, but did not for CSPI slurries. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43637.

“…While most of the testing parameters were set as per the protocols for preparation and testing of plant seed meal-based wood adhesives reported previously, some parameters on post-bonding conditioning and treatments were adopted from European standards EN204 and EN14257 [ 27 , 28 ]. Adhesive slurries were prepared by mixing and stirring WCSM with appropriate deionized water to a solid content of 11% for 1 h at room temperature (22–23 °C).…”

Water washing of cottonseed meal is more cost-efficient and environmentally friendly than protein isolation by means of alkaline extraction and acidic precipitation. Thus, water-washed cottonseed meal (WCSM) is more promising as biobased wood adhesives. In this work, we examined the effects of the particle size on the morphology and adhesive performance of WCSM. Pilot-scale produced and dried WCSM was treated by three grinding methods: (1) ground by a hammer mill and passed through a 0.5-mm screen, (2) further ground by a cyclone mill and passed through a 0.5-mm screen, or (3) further ground by a ball mill and passed through a 0.18-mm screen. Micro-morphological examination revealed two types of particles. The filament-like particles were mainly fibrous materials from residual linters. Chunk-like particles were more like aggregates or accumulations of small particles, with proteins as the major component. Further grinding of the 0.5-mm Hammer product with the Cyclone and Ball mill led to more fine (smaller) particles in the WCSM products. The impact of further grinding on the dry and soaked adhesive strengths was minimal. However, the decrease of the hot and wet strengths of WCSM products by the additional grinding was significant (p ≤ 0.05). Data presented in this work is useful in developing the industrial standards of WCSM products used in wood bonding.
