ABSTRACT:
A method is provided for producing modified starch granules having low viscosity and being capable of absorbing hydrophobic substances. The modified starch granules are prepared by contacting raw starch granules with an .alpha.-amylase and/or glucoamylase the modified starch granules are prepared at 10.degree. to 65.degree. C. to a decomposition percentage of 0.1 to 15%, preferably 0.1 to 1.0%. When cereal starch granules are lightly decomposed with .alpha.-amylase, the viscosity of the granules decreases to such a degree that they are only slightly viscous. The decomposed starch granules may be used in preparing instant liquid foods. By appropriately blending the decomposed starch granules and other non-treated starch granules or other decomposed starch granules, blends of different starch granules having various viscosities can be obtained. The paste or liquid prepared from the enzyme-treated starch granules is smooth and soft to the touch and are useful as base materials for producing various foods. The modified starch granules having low viscosity may be combined with starch granules containing adsorbed aromatic components to produce various foods. Since the enzyme-treated low-viscosity starch granules may be easily produced, they are useful as a raw material in the starch sugar industry.
