The baking properties of flour mainly depend on the gelatinization of the starch and on the enzyme activity (α-amylase) in the flour. The Amylograph-E measures wheat, rye, and rice flour and enables

The heating rate of 1.5°C/min (AACC/ ICC) corresponds with the temperature increase of a bread during baking, i.e. the measuring data of the Amylograph-E provide reliable information about the gelatinization behavior of a flour during baking in practice.

The Principle

A suspension of flour and distilled water is heated at a constant heating rate within a rotating bowl. Depending on the viscosity of the suspension, a measuring sensor reaching into the bowl is deflect­ed. This deflection is measured as visco­sity over time, i.e. vs. tempera­ture, and recorded on-line.

The rapid Amylogram with reduced sample weights and shortened measuring times provides quick results and correlates very well with the standard method.

 

The Amylogram

Define your material (flour/coarse meal) with a simple keystroke, then set any starting temperature for your test (ICC: 30°C). The Amylogram shows

 

 

With rye samples, a keystroke allows to check whether the limits for bread rye quality are met or not (gelatinization maximum ≥ 200 AU, gelatinization temperature ≥ 63°C).
