Description
In the last decade, there has been an increase in the production of environmentally friendly materials, which tends to decrease the effect of humans on the environment. Because of its greater availability, relatively inexpensive, and total composability without toxic components, starch has recently gained popularity as an agro-sourced polymer. Starch is modified to suit its utility in the formulation of the different dosage forms. Due to toxicity in chemical modification, starch modification is typically accomplished by the physical method which is being largely investigated. Modification is the procedure of changing the properties of native starch through physical methods, which included pregelatinized and granular cold-water-swelling starches, annealing, heat-moisture treatments, osmotic pressure treatment, heating of dry starch, and microwave heating. There is stronger correlation between the physicochemical properties & source of starch. Swelling power increases with water absorption capacity and starch granule solubility, respectively. The swelling and solubility power, amylose content, transmittance, water, and lipid holding capacity were all increased by ultrasound treatment. This paper reviews the preliminary physicochemical and morphological properties that revealed the effect of the physical modification of starch as a pharmaceutical excipient.
