The invention relates to the field of daily use chemicals and the pharmaceutical industry, and provides thiadiazole urea-containing acetylated starch and a preparation method and application thereof.Firstly, starch is used as a raw material, and is made to be reacted with chloroacetyl chloride to obtain chloracetyl starch, then nicotinoyl chloride and a sodium azide aqueous solution are reacted to prepare 3-pyridyl isocyanate, the 3-pyridyl isocyanate is made to be reacted with amino-thiodiazole to prepare urea, finally, the chloracetyl starch and the prepared urea are reacted, and through purification, the thiadiazole urea-containing acetylated starch is obtained. The prepared thiadiazole urea-containing acetylated starch has excellent antioxidant activity, and can be applied for preparing an antioxidant, moreover, reaction is simple, convenient and efficient, popularization is easy, the biological activity of the starch is enhanced, an application range of the starch is expanded, and the thiadiazole urea-containing acetylated starch can be widely applied to the fields of daily use chemicals and medicines.
