(57) [Summary] [Purpose] A novel indigestible dextrin containing 75% or more of indigestible ingredients, 13% or more of dietary fiber, low calorie value 1 and low coloring substances and pungent odor. To get. [Structure] (A) The content of indigestible components in components other than glucose is 90% or more, and (B) the amount of glucose residues having only 1 → 4 glycoside bonds in components other than glucose is 25 to 35%, (C) the number average molecular weight of components other than glucose is 900 to 1300, (D) Moreover, the variation range of the calculated value Y of the number average molecular weight calculated by a specific relational expression from the measured value is 20% or less, and (E) the ratio of the weight average molecular weight to the number average molecular weight is 25: 1 or more, (F) Hydrolyzing roasted dextrin obtained by adding hydrochloric acid to corn starch and heat-treating it with α-amylase and glucoamylase, and then separating and removing 1/2 or more of glucose produced Obtained by. |
