Abstract:
1. A method for producing functional starch powder, which comprises: subjecting a potato starch to a pressure reduction to 600 mm Hg and then heat treating the potato starch to a temperature of 100 to 130° C. using compressed steam at a temperature of at least 120° C., heating the potato starch in the presence of 40% by weight or more water at 60 to 150° C. to swell starch particles of the potato starch, and subsequently drying the swollen potato starch particles to obtain a powder mixture comprising the potato starch particles and amylose and amylopectin present on the exteriors of these potato starch particles, wherein the functional potato starch powder has a water retention capacity of 400% or more, a collapse time of 5 hr or more, and a gel indentation load of 200 g or more, 10% or more of all functional potato starch powder particles observable in the field of vision at a magnification of 600 are potato starch particles with a particle size of 50 to 500 μm, the potato starch particles have a structure indented in one or more parts, and 10 to 90% by weight of the total amylose and amylopectin in the functional potato starch powder is present on the exteriors of the starch particles.
