“…In addition to these, the secondary metabolite gosypol is present in cottonseed (Chenoweth et al, 2000). Studies have shown that gossypol is not suitable for human and animal consumption due to its toxic nature (Kumar et al, 2021a;Jacobs et al, 2022). The World Health Organization (WHO) has set the limit for the consumption of gossypol in cotton protein-based products as 450 ppm (Kumar et al, 2021a).…”

The current study focused on characteristic attributes of protein concentrate obtained from oil-free cottonseed. For this, the physicochemical properties namely moisture content, water activity, color, flowability, wettability, and protein solubility of cottonseed protein concentrate (CSPC) were investigated. Water holding capacity (WHC), oil binding capacity (OBC), foaming capacity, foam stability (10 and 30 min), emulsion activity index (EAI) and emulsion stability index (ESI) (10 and 30 min) of proteins were 2.75 g water/g protein, 2.59 g oil/g protein, 29.00%, 93.10% - 69.05%, 6.25 m2/g and 29.27-87.81 min, respectively. Bands regarding CSPC in the 45 kDa molecular weight were detected by sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) patterns. Fourier-transform infrared spectroscopy (FTIR) was used to verify the protein-specific structures. Sheet structures in the surface morphology of CSPC were dominant when scanning electron microscopy (SEM) images were investigated. Thermal gravimetric analyzer (TGA) results showed that the protein concentrate exhibited excellent stability to temperature.
