NUTRIOSE®: Analytical Aspects

The study explains how the manufacturing process of NUTRIOSE® ensures a high level of total fiber content.
The differences between two products of the range, NUTRIOSE® 06 and 10, are also demonstrated.
An Inter-laboratory study, aimed at evaluating the performance and suitability of an enzymatic-gravimetric method (AOAC 2001-03) for quantifying the fiber content of NUTRIOSE®, is described.

Introduction

NUTRIOSE® is a soluble dextrin with a high dietary fibre content. NUTRIOSE® is produced from wheat or maize starch using a highly controlled process of dextrinization followed by a chromatographic fractionation step. The chromatographic step decreases the polydispersity of molecular weight distribution. This process ensures a high fibre content and expected molecular weight distribution, which in turn, relates to the desired biological and rheological behaviour of the product.


Further purification and spray drying steps follow the chromatographic partitioning. Depending on the molecular weight distribution and the botanical origin, different types of product are produced: NUTRIOSE® 06 (FB from wheat or FM from maize) and NUTRIOSE® 10 (FB or FM).
