Print- Method description
Samples (defatted, if necessary) are digested four hours in a manner that simulates the human digestive system with three enzymes (pancreatic alpha-amylase, protease, and amyloglucosidase) to remove starch and protein. Ethanol is added to precipitate high molecular weight soluble dietary fiber. The resulting solution is filtered, and the residue is dried and weighed. Protein and ash are determined on the residue. The filtrate is captured, concentrated, and analyzed via HPLC to determine the value of low molecular weight soluble dietary fiber (LMWSF). Total dietary fiber (TDF) is calculated as the weight of the residue minus protein and ash plus the low molecular weight soluble fiber determined by HPLC analysis.

- Additional information
Measures total dietary fiber, including resistant starch and low molecular weight non-digestible oligosaccharides of DP =3. If a breakout of soluble and insoluble fiber as well as total dietary fiber is desired, please choose our Total, Soluble, and Insoluble Dietary Fiber Rapid Integrated method. Please include notification for samples containing DP2 and DP3 carbohydrates (Isomalto-oligosaccharides (IMO), Maltiltol, Lactose). Dietary Fiber is the portion of the carbohydrates not digested in the human gut. It is composed of both soluble and insoluble components. High-fat (>5%) samples require special handling.
Is this the most suitable fiber test for evaluating my product?
Find your fiber source(s) on the chart and use the alpha reference to see how it aligns with each method. If the alpha reference is fully inside the method circle, that method is optimal for your fiber source(s). If it's outside or touching the circle's edge, the method won't fully capture the fiber. Remember to check applicable labeling regulations for allowed fiber sources.

Common Fiber (Total - Rapid Integrated Method) Test Testing Questions
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
