Whole cherry starch-based preservative, preparation method thereof and cherry preservation method

The invention discloses a whole cherry starch-based preservative, a preparation method thereof and a cherry preservation method, and belongs to the technical field of fruit and vegetable preservation.The starch-based preservative is prepared by mixing special compound modified starch milk, glycerol and ascorbic acid, the starch-based preservative is prepared by size mixing, acidolysis, suction filtration, washing, alkalization, etherification, oxidation, washing, dehydration and preservative preparation. The cherry preservative is green, safe and environment-friendly, can form a layer of protective film on the surface of cherries, inhibits the respiration of cherries, reduces the volatilization of water, prevents the cherries from being damaged and accelerated to rot due to mutual friction and collision in the transportation process, delays the deterioration of the quality, color and glossiness of the cherries, and therefore, the fresh-keeping period of the cherries is prolonged, andthe storage period of the
