AOAC 2017 & 2022 Dietary Fiber, Appropriate Methods for Accurate Results

Mar 27, 2023 | ARTIKEL, BERITA

Fiber is a type of carbohydrate that cannot be digested by the human body so it can help regulate the body’s use of sugar, helping to keep hunger and blood sugar in check. Great sources are whole grains, whole fruits and vegetables, legumes, and nuts (Institute of Medicine, 2005). Along with its development, the  indigestible oligosaccharides (DP = 3-9) are also included in the definition of dietary fiber.

Dietary Fiber contained in food and drinks is able to absorb water and attract glucose, so it reduces the availability of glucose. This situation can reduce the blood glucose increase and keep it under control (Ministry of Health of the Republic of Indonesia).

PerBPOM No. 26 of 2021 About Nutrition Fact on the Processed Food Labels
If declared available carbohydrates, it must be accompanied by the analysis result of dietary fiber. Dietary fiber must be declared if it is present in significant quantities, more than 0.5 grams per serving.

How SIG Helps
As an ISO 17025 accredited laboratory, SIG success in developing a dietary fiber analysis (the latest CODEX definition covering oligosaccharides), FIRST IN INDONESIA,  based on AOAC 2017.16 for total dietary fiber and AOAC 2022.01 for soluble and insoluble dietary fiber using a Rapid Integrated Assay that can overcome the limitations of the method of dietary fiber test by AOAC 985.29 and AOAC 991.43.

This method combines gravimetry for the detection of insoluble dietary fiber and high molecular weight soluble dietary fiber such as cellulose, lignin, and resistant starch, and HPLC instrumentation for the detection of refractive index to detect types of soluble dietary fiber with low molecular weight such as oligosaccharides: FOS, GOS, fructans, and inulin. So the dietary fiber content in the sample is calculated completely and accurately.
