Abstract

Fat-praeparates of cow and pork have been investigated by small-angle X-ray scattering methods. Dependent on the temperature these fats show distinct X-ray interference patterns in the small-angle region. Hence complete phasediagrams of the fats in the temperature region between -20 degrees C and 55 degrees C could be estimated. Using the intensity distribution of the X-ray scattering the electron-density distribution along one direction of the ground-cells of the fat crystals were calculated.

摘要

已通过小角X射线散射法对牛脂肪和猪脂肪的预制品进行了研究。这些脂肪在小角区域呈现出取决于温度的独特X射线干涉图案。因此,可以估算出这些脂肪在-20摄氏度至55摄氏度温度范围内的完整相图。利用X射线散射的强度分布,计算了沿脂肪晶体基元胞一个方向的电子密度分布。
