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

What is claimed is: 
     
         1 . A functional starch powder having 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. 
     
     
         2 . A functional starch powder according to  claim 1 , wherein the powder was dispersed in water, and the amount of amylose and amylopectin ranges from 10 to 90% by weight and is in a swollen or dissolved state. 
     
     
         3 . A functional starch powder according to  claim 1 , which comprises starch particles with a particle size of 50 to 500 μm having a structure indented in one or more parts. 
     
     
         4 . A composition comprising functional starch powder according to  claim 1  and one or more active ingredients. 
     
     
         5 . A composition according to  claim 4 , wherein the one or more active ingredients are selected from pharmaceutically active ingredients, agrochemical ingredients, ingredients for fertilizer, ingredients for feed, ingredients for food, ingredients for cosmetic, coloring maters, flavoring materials, metals, ceramics, catalysts and surfactants. 
     
     
         6 . A composition according to  claim 4 , which controls the release of the active ingredient(s) so that the release may be sustained release or rapid release. 
     
     
         7 . A functional starch powder according to  claim 2 , which comprises starch particles with a particle size of 50 to 500 μm having a structure indented in one or more parts. 
     
     
         8 . A composition comprising functional starch powder according to  claim 7  and one or more active ingredients. 
     
     
         9 . A composition according to  claim 8 , wherein the one or more active ingredients are selected from pharmaceutically active ingredients, agrochemical ingredients, ingredients for fertilizer, ingredients for feed, ingredients for food, ingredients for cosmetic, coloring maters, flavoring materials, metals, ceramics, catalysts and surfactants. 
     
     
         10 . A composition according to  claim 9 , which controls the release of the active ingredient(s) so that the release may be sustained release or rapid release.
