114/1 Method for using the Brabender Extensograph

Methods Type: Generic Methods
Key data
Number: 114/1
Analyte: Brabender Extensograph
Matrix: Wheat
Year of Approval: 1972
Year of Last Revision: 1992
Scope: This standard specifies a method, using the Brabender Extensograph, for determination of the rheological properties of a wheat flour dough in an extension test. The recorded load-extension curve is used to assess general quality of flour and its response to improving agents. The method is applicable to flour from wheat (Triticum aestivum L.).

For the purposes of this standard, the following definitions apply:

  • Extensograph water absorption
    The extensograph water absorption is the volume of water, expressed in millilitres per 100 g of flour at 14.0 % moisture content, required to produce a dough with a consistency of 500 FU after 5 min mixing, under the operating conditions specified in this standard.
    This standard specifies the extensograph water absorption. The ICC Standard No. 115/1 specifies the farinograph water absorption, the definition of which differs from that of the extensograph water absorption. According to the experience the extensograph water absorption is approximately 2 % less than the farinograph water absorption.
  • Stretching characteristics (of dough)
    The stretching characteristics of a wheat flour dough are given by:
    • the resistance of the dough to extension, expressed in arbitrary units (Extensograph Units, EU), and
    • the extent to which it can be stretched before breaking, expressed in millimetres
    • transposition of the chart paper in the recorder, under the operating conditions specified in this standard.
