Effect of acetylation and heat moisture treatment (HMT) on physicochemical, morphological and rheological properties of buckwheat starch (Fagopyrum esculentum) was investigated.  Acetylation, decreased amylose content of starch with increase in water binding capacity, oil binding capacity, swelling power, solubility and sediment volume. Acetylated starch showed improved paste clarity (five days storage) and increased peak viscosity as compared to native starch. Amylose content, water binding capacity, and oil binding capacity was also improved in HMT starch. The increase in onset temperature of viscosity development and the decrease in peak viscosity was observed in HMT starch. HMT decreased swelling power and solubility of native starch.
