Safflower meal has higher protein level, up to 25%-35%, comparing to other plant proteins. By measuring the molecular weight and microstructure, the molecular weight of safflower seed meal protein was found to be generally between 20-45 kDa, and the distribution of protein was more concentrated. By using scanning electron microscopy (SEM), protein from safflower seed meal obtained by ultramicro pulverization was found smaller and more dispersed, with a larger specific surface area and a smaller size. The agglomeration ability of superfine comminution was 2.5 times as strong as that of the ordinary comminution. The intermolecular cohesion was 16.962, which was 45.68% higher than that of ordinary comminution. Protein powder fluidity was 1.06 times higher than normal comminution. In other words, its fluidity was slightly worse than the ordinary comminution. The ultrafine pulverized safflower seed meal had higher solubility, emulsifying and foaming properties than the normal pulverized safflower seeds, which were 56.83%, 41.60% and 36.53%, respectively. Overall, the functional characteristics of ultrafine pulverized safflower seed meal had been improved and its comprehensive use could be made.
