Preparation method of grape seed procyanidine starch aerogel

The invention relates to the technical field of starch aerogel preparation, and discloses a preparation method of grape seed proanthocyanidin starch aerogel, which comprises the following preparation steps: S1, dissolving proanthocyanidin in absolute ethyl alcohol for later use after the proanthocyanidin is completely dissolved; s2, uniformly mixing starch and a cross-linking agent in distilled water for later use; s3, mixing the solution obtained in the step S2 and the solution obtained in the step S1 under a high-temperature condition, and gelatinizing; s4, the mixed solution obtained in the S3 is cooled and poured into a mold, then the mold is placed in a refrigerator with the temperature environment being 4 DEG C to be stored, the mold is taken out and cut into small sections after storage is completed, and a solid mixture is obtained; and S5, carrying out drying treatment on the solid mixture obtained in the step S4. According to the proanthocyanidins starch aerogel prepared by the preparation method dis
