High energy electron beam irradiations up to 900 mrads were given to tristearin and triolein. Differential thermal analysis and x‐ray diffraction measurements revealed that the degree of crystallinity decreased with radiation dose after an initial small rise and that the unstable forms in crystal modification were increasingly stabilized. Measurements of intrinsic viscosity and gel fraction for solutions of tristearin and triolein showed that the gel formation took place at about 700 and 350 mrads, respectively. The number of unsaturated bonds determined by iodine absorption increased with radiation dose in tristearin but decreased in triolein.
