Asdescribed in the method, the starch from potatoes, corn, andcassava are selected; the substitute reagent is acetic anhydride;the reagents for pH value adjustment include NaOH solution of 0.1mol/L and HCL solution of 0.1 mol/L; the acetyl groupconcentration ranges from 0.5% to 2.5%. The starch is converted toacetylated starch through optimized acetylation substitution tosupplement necessary dietary fibers in foods and diets of peopleand animals. The invention is applicable to: A. daily and healthfoods including baked food, meat products, dairy products, etc.for healthy people; B. dietary therapy of diabetes, obesity,cerebro—cardiovascular diseases, high blood lipid, digestivesystem diseases, and other chronic diseases; C. foods and healthproducts for pets; D. animal husbandry feeding.
