The Total Dietary Fiber Assay Kit (TDFR) enables precise measurement of total, soluble, and insoluble dietary fiber in a wide range of food and beverage products.
Dietary fiber refers to the portion of carbohydrates in food that resists digestion in the small intestine and proceeds to the large intestine, where it undergoes partial or complete fermentation. This unique behavior is linked to a variety of well-established health benefits, including improved digestive function, regulation of blood sugar levels, and support for cardiovascular health.
Fiber is a complex matrix of organic compounds. It includes water-loving (hydrophilic) substances such as soluble and insoluble polysaccharides and non-digestible oligosaccharides, as well as water-resistant (hydrophobic) components like cutins, suberins, and lignins. These diverse chemical structures require robust analytical techniques to ensure accurate quantification.
The TDFR kit outlines two distinct procedures for fiber analysis. One method allows for the separate determination of soluble and insoluble fractions, while the other focuses on total dietary fiber content. Both approaches utilize a carefully optimized blend of enzymes and reagents to mimic physiological digestion and isolate fiber components for measurement.
Additional Information: This product is supported by a letter of endorsement from Dr. Leon Prosky, one of the original developers of the dietary fiber measurement methodology. His endorsement underscores the scientific integrity and reliability of the assay.
