Natural aggregation method and extraction method of sesame protein

The invention belongs to the technical field of agricultural product processing, and particularly relates to a natural aggregation method and an extraction method of sesame protein. The natural aggregation method of the sesame protein provided by the invention comprises two steps of water soaking and germination, in the germination process, protease in sesame is continuously activated, and meanwhile phytic acid is continuously decomposed, so that a protein structure stored by the sesame is expanded, and then protein modification is carried out; proteins, starch, phenols and other substances are promoted to generate rearrangement and aggregation through hydrophobic interaction, so that aggregation protein with high molecular weight is generated. Compared with the original protein contained in the ungerminated sesame, the aggregation protein in the germinated sesame has more excellent functional properties. Compared with existing machining and hot working, the method has the advantages of being small in energy
