Abstract: Functional starch powder of 400% or more water retention capacity, 5 hr or more collapse time and 200 g or more gel indentation load.

Abstract: Functional starch powder of 400% or more water retention capacity, 5 hr or more collapse time and 200 g or more gel indentation load. This functional starch powder is produced through the step of heating a starch raw material in the presence of water at 60 to 150° C. so as to swell starch particles of the starch raw material and the subsequent step of drying the thus swollen starch particles so as to obtain a powder mixture comprising starch particles and, lying in the exterior thereof, amylose and amylopectin.

Abstract: A disintegrant for tablets includes an ?-1,4-glucan having a degree of polymerization of not less than 180 and less than 1230 and a dispersity (weight average molecular weight “Mw”/number average molecular weight “Mn”) of not more than 1.25 or a modified product thereof. A binder for tablets includes an ?-1,4-glucan having a degree of polymerization of not less than 1230 and not more than 37000 and a dispersity of not more than 1.25, or a modified product thereof. A binding-disintegrating agent for tablets includes a low molecular weight ?-1,4-glucan or a modified product thereof, and a high molecular weight ?-1,4-glucan or a modified product thereof.

Abstract: The present invention provides a cationic starch prepared by roasting starch under the presence of a cationic polymer, a method for preparing the cationic starch, and a method for making paper board with the cationic starch. The method for making paper board of the present invention provides high retention of starch in paper board, enhances paper board strength in a high level and reduces a load of treating waste water from a paper machine, in comparison with the starch which has conventionally been employed for paper making.
