Abstract
A chemical fluidification process for a starchy material, which is carried out in a reactor suitable for continuous operation and with a humidity of the reaction mix (starch included) of less thank 25%, which consists in subjecting a starchy material to the hydrolyzing action of a chemical agent. The dwell time of the starchy material in the fluidification reactor is more than 5 minutes and less than 30 minutes. The temperature at the core of said reactor is more than 60° C. and less than 100° C. approximately, a conversion process comprising said chemical fluidification, and starchy materials obtainable by such processes.
