Preparation method and application of natural spice based on snake fruits

The invention discloses a preparation method and application of natural spice based on snake fruits. The preparation method specifically comprises the following steps: S1, taking and crushing peels of the snake fruits; S2, adding the crushed peels into deionized water for extraction, and then adding a combined enzyme for hydrolysis; S3, adding ethanol into the enzymolysis product in the step S2, performing heat extraction, performing centrifugation to obtain peel residues and an extracting solution, then taking the extracting solution, and allowing the extracting solution to pass through a filter membrane; S4, adsorbing the peel residues with zeolite, then washing the zeolite, and adding a washing solution into the extracting solution for later use; S5, carrying out ethanol heat extraction on the peel residues, to obtain a secondary extracting solution; and S6, mixing the two extracting solutions obtained in S4 and S5, filtering, taking a clear solution, and carrying out low-temperature vacuum concentration o
