Preparation method of amylose inclusion complexation carrier

The invention discloses a preparation method of an amylose inclusion complexation carrier. The method comprises the following steps: preparing a starch raw material into starch milk by a disodium hydrogen phosphate-sodium dihydrogen phosphate buffer solution, adjusting the pH to 4.5-6.5, putting the starch milk in an enclosed container for gelatinization; after the gelatinization, cooling the gelatinized liquid, adding a debranching enzyme, stirring and reacting at 45-65 DEG C for 1-3 hours; adjusting the pH to 5.5-7.0, adding alpha-amylase, stirring and reacting at 45-110 DEG C for 1-10 min, performing enzyme deactivation; adding an iodine-potassium iodide mixed solution prepared by water, controlling the concentration of the potassium iodide in the mixed solution to be 5-20 mg/mL; performing thermal insulation and stirring at 60-80 DEG C for 10-20 min; performing neutralization to obtain a pH of 6.0-6.5, drying, and crushing. The amylose carrier prepared by the invention can realize inclusion complexation of substances of essence perfume, aliphatic acid, inorganic micromolecules, and the like, and has wide applications in industries of food, medicine, cosmetics, chemical engineering, and the like.
