摘要:
A process for modifying starches comprises atomising an aqueous slurry of a non-pregelatinised, granular, high amylose starch into to an internal chamber in a bi-fluid nozzle of a dryer and treating the atomized slurry, in the internal chamber, with medium pressure steam to produce a slurry of partially treated starch granules followed by discharging the slurry into a reactor where it is contacted with superheated steam to produce dry, particulate, cold water-swelling, intact, high amylose starch granules. The cold water-swelling, intact, high amylose starch granules have greater than 15% solubles. At a starch concentration of 1%, in UDMSO (9 volumes DMSO and 1 volume 6M urea) at 25° C., the ratio of apparent viscosity of said cold water-swelling, intact, high amylose starch granules to the apparent viscosity of the parent non-pregelatinised, granular, high amylose starch is lower than 1.00. The cold water-swelling, high amylose granular starch of the invention is useful in the manufacture of food products, especially confectionery products and convenience food products.
