Abstract
The present invention provides a method for producing dietary fiber that has a mild sweet taste by reducing sugars and provides by-products having high added values, and dietary fiber produced by the method. The dietary fiber may be produced by including: liquefying roasted dextrin; and adding enzymes including α-amylase, β-amylase, and maltogenic amylase to the liquefied roasted dextrin, and saccharifying the same.
Claims6
A method for producing dietary fiber comprising:
- (a) liquefying roasted dextrin;
- (b) adding enzymes including α-amylase, β-amylase, and maltogenic amylase to the liquefied roasted dextrin, and saccharifying the same to produce a sugar solution;
- (c) filtering the sugar solution obtained in the step (b);
- (d) decolorizing the filtered filtrate by treatment with activated carbon;
- (e) purifying the decolored filtrate by passing it through an ion exchange resin;
- and
- (f) concentrating the filtrate after the purifying, followed by performing column chromatography filled with a strongly acidic cation exchange resin to obtain a dietary fiber sugar solution,
- wherein the α-amylase is added in an amount of 0.01 to 0.1% (w/w), the β-amylase is added in an amount of 0.01 to 0.1% (w/w), and the maltogenic amylase is added in an amount of 0.01 to 0.5% (w/w), based on a total amount of the liquefied roasted dextrin;
- and
- wherein the enzymes are simultaneously added.
