US Patent No. 10,729,144 (Aug. 4, 2020), P. McKee, et. al., assigned to Alto-Shaam, Menomonee Falls, Wis.

New starch for convenience foods

This patent demostrates a process for modifying starches by atomizing an aqueous slurry of a non-pregelatinized, granular, high-amylose starch into an internal chamber in a bi-fluid nozzle of a dryer. Afterward, the process calls for treating the atomized slurry, in the internal chamber, with medium pressure steam. This slurry of partially treated starch granules is discharged into a reactor where it is contacted with superheated steam to produce dry, particulate, cold water-swelling, intact, high-amylose starch granules. The starch is useful in making food items, especially confectionery and convenience food products.
