AUTOMATED METHOD AND SYSTEM FOR THE ANALYSIS OF TOTAL DIETARY FIBER

摘要

The invention consists of a method for determining Total Dietary Fiber (TDF) and its sub-fractions, Insoluble Dietary Fiber (IDF) and Soluble Dietary Fiber (SDF) in food and feed samples which utilizes flexible reaction/filtration containers that can be divided into one or more sections for capturing the IDF and SDF fractions separately or for capturing TDF in its entirety. Each container is fashioned as a bag that can be temporarily sealed in multiple locations to create multiple sections and is made of non-porous and porous material. Use of these containers eliminates the need for problematic transfers of mixtures from beaker to filter, and vastly improves the filtration process.

主权项

1. A flexible bag used for analyzing a sample having an insoluble fraction and a soluble fraction comprising:
a reaction section comprising a non-porous polymer film for combining the sample with a liquid; and a filtration section comprising a porous filter for filtering the sample after combining in the reaction section, wherein the porous filter is attached to the inside of the non-porous polymer film of the reaction section, wherein a portion of the non-porous polymer film of the reaction section surrounds and contains a portion of the porous filter.
