Combine with COEX for cold extraction before fiber analysis.
- FIWE is a fiber analyzer suitable for raw fiber extraction, conventionally known as an indigestible residue.
- The Weende method is the oldest analytical procedure still in use today, in which fiber concentration is measured as crude fiber (CF).
- Weende method has been now largely replaced by the Neutral Detergent Fiber (NDF), a method developed by Van Soest, being now the most common measure of fiber used for animal feed analysis. It measures most of the structural components in plant cells (including lignin, hemicellulose, and cellulose), but not pectin.
- Another application is Acid Detergent Fiber (ADF), that is a portion of the plant fiber and includes cellulose, lignin and variable amounts of xylans.
- FIWE fiber analyzer is also suitable for Acid Detergent Lignin (ADL) determination and Wijkstrom technique, a modification of Weende method.
- Perform single or multiple extractions including boiling, rinsing and filtration steps with the maximum reproducibility available.
- No sample transfer prevents any possible sample loss, as crucibles can also be used as sample vessels during weighing, drying, and washing.
- Pre-heat the reagents with RC2 hot plate(included), and pour them directly into the system.
An extremely efficient heating element speeds up the analysis, ensuring a rapid heating of the sample, previously mixed with pre-heated reagents.
Also after the second reagent addition, the heating element grants a fast re-heating of the solution, for conspicuous saving in terms of time.
In fact, FIWE Series drastically reduces the time required for the analysis: the equivalent manual procedure will require more than 6 hours, compared to the 2 hours with FIWE.
The most significant reasons to test the fiber content are related to:
The quantity of fiber is important to keep the digestive system healthy and functional. Too much fiber can cause digestive problems; a low fiber intake irregularities in the functioning of the digestive tract.
Authorities of almost all countries require manufacturers of food & feed products to declare the fiber content as part of the nutritional table.
