cookies spread were affected by storage temperature and sonication . The degree of spread resulting in final cookie diameter is controlled by the spread rate and set time. Set time is determined by the level of free water in dough that can act as solvent and the strength of the doug. Therefore, the degree of spread is largely determined by the spread rate , The fluid character of non UStreated IES contributed to a higher spread rate and therefore significantly larger spread. with a larger spread, lower cookie heights resulted.
