FIWE units are suitable for the crude fiber analysis and detergent fiber extraction according to official standard methods. These are Fiber Analyzers that use pre-heated reagents for fiber analysis according to Weende, Van Soest and other official methods.
Vegetables and derived products are made up of substances belonging to different categories
Carbohydrates, proteins, fats, mineral salts
A non-digestible component consisting of polymers (lignin, cellulose, hemicellulose, pectin) called "fiber"
Nutritional importance for analysis: Too much fiber can cause digestive problems.
Low fiber intake creates 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
Weende Method: The oldest analytical procedure still in use today, in which fiber concentration is measured as crude fiber (CF)
Neutral Detergent Fiber (NDF) Method: A method developed by Van Soest, being now the most common measure of fiber used for animal feed analysis
Rapid analysis - 2 hours vs. 6 hours with manual systems
Back-pressure pump prevents clogging of crucibles
Total raw fiber extraction using Weende technique
Neutral & acid detergent fiber with NDF, ADF, Van Soest extractions
Acid detergent lignin extraction with ADL & Van Soest methods
Fiber fraction analysis (cellulose, hemicellulose & pectin)
Links boiling, rinsing and filtration
Single or multiple samples can be processed
Reagent preheating on RC 2 hotplate (provided)
