摘要: 采用超临界二氧化碳对油菜蜂花粉进行处理,通过快速卸压使蜂花粉细胞壁破裂,经扫描电镜观察不同压力对蜂花粉破壁的影响,并比较了超临界二氧化碳破壁油菜蜂花粉和未破壁花粉油脂在脂肪酸组成上的差异。结果表明,超临界二氧化碳压力越高,花粉细胞的破壁效果越好,破壁后与未破壁的蜂花粉油脂脂肪酸组成差异显著。超临界二氧化碳对蜂花粉进行破壁在较低温度下进行,破壁时间短,工艺流程简单,是一种理想的蜂花粉破壁新方法。

Abstract: Bee pollen was treated with supercritical CO2. The cell wall of the pollen was broken by fast decreasing the pressure and the effect of pressure was investigated through SEM. The difference of fatty acid composition between cell wall-broken rape pollen oil and the control was investigated. The results demonstrated that the wall-broken rate increases when the pressure goes up. The fatty acid composition displays significant difference between cell wall-breaked rape pollen oil and the control. The procedure is under low temperature, with short wall-broken time. So the process is a promising and ideal method for breaking cell wall.

Key words: bee pollen, cell wall-broken, supercritical CO2, fatty acid composition
