Description
Technical field
The present invention relates to a kind of food auxiliary material and preparation method thereof and its application, more particularly to a kind of soluble dietary fiber
And its application.
Background technology
Dietary fiber refer to can not by edible plants cell that digestion is digested and assimilated, lignin, polysaccharide and
The summation of related substances, in terms of specific chemical constituent, dietary fiber includes cellulose, hemicellulose, pectin, glucan, wood
Quality etc..Dietary fiber is that health diet is indispensable, and it remains digestive system health, while it is fine to absorb enough meals
Dimension can also prevent diabetes, angiocardiopathy, cancer and other some diseases.Dietary fiber can be divided into two classes, soluble meals
Fiber (SDF) and insoluble dietary fiber (IDF) are eaten, SDF is water-soluble, from pectin, phycocolloid, konjaku etc., there is reduction
Blood fat and blood glucose etc. act on.
Tea, it is bud-leaf processed manufactured a kind of low heat value, the non-alcoholic drink of Theaceae Camellia Plants tea.Tealeaves
Composition mainly includes water, protein, amino acid, caffeine, polyatomic phenol, carbohydrate, lipid, mineral matter, organic acid etc..
Tea is as drink, and mainly edible is its water soluble ingredient.Tea has long medicinal history and wide in range health-care efficacy, early
Just on the books before thousands of years, tealeaves was once referred to as " medicines of ten thousand diseases ".As people deepen continuously to tealeaves research, the guarantor of tea
Strong effect increasingly causes the concern of all circles.
Chinese tea aboundresources, the prospect of comprehensive development and utilization are very wide.The tea products of research report are more at present
See extraction of functional components etc. in tea beverage, tea health-care food, tealeaves.Produce green tea soluble dietary fiber beverage
Research is not yet seen in report.
Traditional tea dietary fiber extraction technique uses chemical method more, but this method can pollute to environment, extract simultaneously
Also chemical substance can be introduced in thing.The present invention prepares soluble dietary fiber using the method for cellulase degradation, green,
Yield is high, has good popularizing application prospect.
The content of the invention
