To investigate the effect of preparation methods of cottonseed meals on protein properties, the physicochemical and functional properties of proteins isolated from hot-pressed solvent extraction cottonseed meal (HCM), coldpressed solvent extraction cottonseed meal (CCM) and subcritical fluid extraction cottonseed meal (SCM) were investigated. Cottonseed proteins had two major bands (at about 45 and 50 kD), two X-ray diffraction peaks (8.5° and 19.5°) and one endothermic peak (94.31 °C–97.72 °C). Proteins of HCM showed relatively more β-sheet (38.3%–40.5%), and less β-turn (22.2%–25.8%) and α-helix (15.8%–19.5%), indicating the presence of highly denatured protein molecules. Proteins of CCM and SCM exhibited high water/oil absorption capacity, emulsifying abilities, surface hydrophobicity and fluorescence intensity, suggesting that the proteins have potential as functional ingredients in the food industry.
