Objective:
To determinate the total, soluble and insoluble dietary fiber in different kinds of food so as to provide the references for guiding the diet for control and prevention of chronic diseases.
Methods:
The contents of total, soluble and insoluble dietary fiber in 33 food samples were determined by enzymatic-gravimetric method.
Results:
The average total dietary fiber(TDF, g/100 g edible part) in dry beans, flesh beans and whole grains were 36%, 14%, 16% respectively, and that of refine grains, vegetables and fruits were lower than 10%. The contents of soluble dietary fiber in beans were highest, and the contents of insoluble dietary fiber in dry beans and other grains were higher.
Conclusion:
The repeatability of the analysis method was good, the contents and pattern of dietary fiber in different kinds of food were largely varied.
