摘要
以热榨棉籽饼、冷榨棉籽饼和亚临界萃取棉籽饼为试验材料,对其饼粉的理化特性与功能特性进行研究。结果表明,热榨棉籽饼粉的粗蛋白和游离棉酚质量分数分别为56.23%～60.86%和38～123mg·kg^(-1)。而冷榨和亚临界萃取棉籽饼粉有较高质量分数的蛋白质,未检测出游离棉酚。冷榨和亚临界萃取棉籽饼粉的颜色较浅,亮度较高,分散性好。亚临界萃取棉籽饼粉的吸油能力最强。冷榨和亚临界萃取棉籽饼粉乳化性较优,溶解性较好,而乳化稳定性较差。
The physicochemical and functional properties of flour from hot-pressed solvent extraction of cottonseed meal(HCM),cold-pressed solvent extraction of cottonseed meal(CCM)and subcritical fluid extraction of cottonseed meal(SCM)were systematically analyzed.The protein mass fraction and free gossypol mass fraction of HCM were 56.23%-60.86%and 38-123 mg·kg^-1.CCM and SCM had high protein mass fraction,and free gossypol mass fraction was not detected in CCM and SCM.CCM and SCM displayed light color,high brightness and good dispersibility.SCM showed highest oil absorption capacity.High emulsifying activity,good solubility and low emulsion stability were observed in CCM and SCM.
