Crude Fiber Extraction Rack

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

High Performance
~ Rapid analysis - 2 hours vs. 6 hours with manual systems
~ Reliable results
~ High reproducibility
~ Back-pressure pump prevents clogging of crucibles

Versatile
~ 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

Full System
~ Reagent preheating on RC 2 hotplate (provided)
~ Same crucibles used for weighing, drying & washing - no loss

Recommendations
~ Combine with COEX for cold extraction before fiber analysis
