Raw & Dietary Fiber Determination by Velp Scientifica Srl

FIWE units are suitable for the crude fiber analysis and detergent fiber extraction according to official standard methods.

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.

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 is also suitable for Acid Detergent Lignin (ADL) determination and Wijkstrom technique, a modification of Weende method.

FIWE is a fiber analyzers that uses pre-heated reagents for fiber analysis according to Weende, Van Soest and other official methods.

High Performance

• Rapid analysis – 2 hours v 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

• Solvent preheating on RC 2 hotplate (provided)
• Same crucibles used for weighing, drying & washing – no loss

Choice of Models

• FIWE is available in different configurations:
  FIWE 3, a 3-position raw fiber analyzer
  FIWE 6, a 6-position raw fiber analyzer

Recommendations
Combine with COEX for cold extraction

• Cold extractor that performs rapid fat extraction directly in the same glass crucibles that are used by the FIWE Series for raw fiber analysis.
• Reduces fat to below 1% improving analytical precision
• No loss – reduced sample remains in same crucible for analysis
• Immediate raw fiber extraction after fat extraction here
• Processing of individual or several samples
• Back-pressure pump keeps crucibles free from clogging
• Fatty components collected for easy disposal
• All reagents can be added through the same channel
