Description
Technical field
The present invention relates to health products processing technique field, in particular to a kind of high-quality dietary fiber and its preparation
Method.
Background technology
Dietary fiber is a kind of complicated mixture, according to deliquescent difference, can be classified as water-soluble dietary fiber
(SDF) and two major class of water insoluble dietary fiber (IDF)：Water insoluble dietary fiber (IDF) refers to not by human body alimentary canal enzyme
Digestion and the part dietary fiber insoluble in hot water, be mainly cell membrane composition, including cellulose, hemicellulose,
Lignin, chitosan and vegetable wax etc..Water-soluble dietary fiber (SDF) refers to not by human body alimentary canal enzymic digestion.But dissolve in
Warm water or hot water and its aqueous solution again can be by the part dietary fibers of its 4 volume ethanol reprecipitation, it is formed mainly
Gelatin substance such as pectin, Arabic gum, carrageenan, melon bean gum, more carragheen, sore glue, xanthans, agar etc., also have gala
Sugared mannosan, glucan, sodium alginate, carboxymethyl cellulose and fungi polysaccharide etc..
Dietary fiber can be divided into according to the quality of dietary fiber by two classes:Full diet fiber and high-quality dietary fiber：
Full diet fiber is that a kind of noenergy adds and fills agent, and for wherein soluble component below 3%, its physiological activity is relatively low.Gao Pin
The soluble component content of matter dietary fiber should be up to more than 10%, and expansive force (EXP) is more than 10ml/g, and retention ability (WHC) is not small
In 7g/g, its physiological activity is stronger, has obvious health-care effect, can be as additive and the health food original of various food
Material.
The content of the invention
The present invention provides a kind of preparation method of high-quality dietary fiber, it is intended to it is fine to prepare the higher meals of quality
Dimension.
The present invention provides a kind of high-quality dietary fiber, its SDF/IDF can reach more than 1.9, its retention ability is reachable
More than 12g/g, water swelling power is up to more than 15ml/g.
What the present invention was realized in：
