Abstract:
A method for the preparation of a glucose polymer having an ion-exchanging ability comprises the steps of drying a mixed aqueous solution containing a raw glucose polymer and a polyvalent carboxylic acid to thus form a uniform powdery mixture and then subjecting the powdery mixture to a heat treatment. The method of the present invention can ensure the achievement of a high reaction efficiency, is economically advantageous since it never requires the use of any expensive catalyst and does not require the use of any complicated step for the removal of impurities. The glucose polymer prepared by the method of the present invention is biodegradable and can be used in, for instance, various foods and/or builders.
Abstract:
A doughnut like a dumpling covered with sesame seeds is prepared using a powdery raw material, which comprises 50 to 80 parts by weight of ungelatinized starch, 6 to 25 parts by weight of pregelatinized starch, 7 to 30 parts by weight of wheat flour and 7 to 25 parts by weight of a saccharide. Dough used for the preparation of a doughnut like a dumpling covered with sesame seeds is obtained by adding water and, if needed, a seasoning component to the foregoing powdery raw material to thus form dough, dividing the resulting dough into small pieces and forming each small piece into a desired shape and, if needed, stuffing the shaped dough with fillings. The foregoing doughnut can be prepared by frying the foregoing dough. The doughnut like a dumpling covered with sesame seeds is excellent in the storage stability and has excellent sticky and resilient feeling upon eating like a rice cake.
