In this work, maize starch was used to demonstrate a novel method which enables the preparation of starch films and coatings with good
thickness control. 5% starch in de-ionized water (w/v) was gelatinized at 120 8C for 30 min, subsequently small quantities of dispersant and
ethanol were added and subjected to ultrasonic disruption to make a stable modified starch solution. Electrohydrodynamic behavior of this
solution was studied and optimum conditions for film preparation were determined. The solution was then electrosprayed in the cone-jet mode and
films were collected on a rotating plate. Film thickness was investigated by electron microscopy. Films of varying thickness were prepared by
varying the electrospraying time and their characteristics are compared with solvent-cast films.
