Abstract:The autoclave method combined with repeated freezing and melting for preparation of wheat resistant starch was studied. And the physicochemical and structure properties of wheat resistant starch were investigated. The results showed that after freezing and melting treatment for 6 times, the content of wheat resistant starch reached the highest (18.31%). The water-holding ability, solubility and swelling capacity were influenced by the times of freezing and melting treatment.
