An amylaceous material is readily dispersible in water at all temperatures, dissolves at high temperature, has a marked capacity for thickening by absorption of water, and exists in the form of macroscopic particles between 0.5 and 5 mm in size. The material has a solubility (5) in water of 15 to 65 %, and a swelling ratio (6) in water of 15 to 45 %. S = (initial mass (dry matter) - mass of cull (dry matter))/initial mass (dry matter) x 100, and G = (water added initially - volume of supernatant)/mass of cull (dry matter), S and G being calculated for 0.5 g samples of dry matter stirred in 50 ml of water for 1/2 an hour on a water bath at 65 DEG C and then centrifuged. To prepare the material, a medium containing starch, 30 to 50 % by weight of water, referred to the mass of starch, and if necessary an amylose-complexing agent is subjected to a wave treatment (0.9-300 GHz). The paste so obtained is then fragmented and dried. |
