The structure and property relationship of starch was studied under different pH namely 3.8, 7.1 and 12.5. The acidified starch exhibited a degraded form of starch. In a similar manner the structure and property relationship of starch in the presence of Ferrite at three different pHs, as mentioned above were studied. The starch Ferrite nano composite prepared under acidic condition showed a degraded form of starch. The structure and property relationship of the above mentioned system were characterized by FTIR, DSC, TGA and SEM like analytical techniques. Further, the settling velocity of starch was carried out under different experimental conditions.
