<p>A process of producing a highly hydrated hyper-swollen gelatinised starch is described and comprises: combining a starch-containing product with a working fluid (e.g. water) to form a mixture; inducing the mixture to flow through an inlet into a passage; and injecting a high velocity (e.g. supersonic) transport fluid into the mixture through a nozzle communicating with the passage; wherein the injection of the high velocity transport fluid: applies a shear force to the mixture such that the mixture is atomised and forms a vapour and droplet flow regime; forms an at least partial vacuum within the passage downstream of the nozzle; and generates a condensation shock wave within the passage downstream of the nozzle and vacuum by condensation of the transport fluid to produce a hyper-swollen hydrated gelatinised starch. Hyper-swollen hydrated gelatinised starches, polysaccharides and polyolefins made by the process of the present invention are also provided and have broad utility, for example in food, medical, paper, cosmetic, textile and construction industries.</p> |
