Sacha inchi small molecule peptide powder and preparation method thereof

The invention discloses sacha inchi small molecule peptide powder and a preparation method thereof. The preparation method comprises the following steps of drying sacha inchi oil residues, performingcrushing to obtain powder, and performing degreasing treatment so as to obtain sacha inchi oil residue degreased powder; mixing the sacha inchi degreased powder with water to obtain mixed liquid, performing heating for the first time, performing heat insulation for the first time, and then performing cooling; adding alkali protease to the cooled mixed liquid A, regulating pH to 8-10, performing heating for the second time, and performing heat insulation for the second time to obtain first-time enzymatic hydrolysate B; performing enzyme deactivation, performing cooling to room temperature, thenadding neutral protease, regulating pH to 7, performing heating for the third time, and performing heat insulation for the third time so as to obtain second-time enzymatic hydrolysate C; performing enzyme deactivation once ag
