Analyze the visco-elastic properties of wheat dough with the latest state-of-the-art evolution of the international reference

Applications :

1. For Storage Operators

  • Secure the buying and selling of wheat and our usingan international reference
  • Monitor wheat quality upon reception
  • Select and classify wheats according to their future use
  • Detect insect contaminated wheat

2. For Bakers

  • Monitor the conformity of incoming flour
  • Test new compositions
  • Control additives

3. For Millers

  • Optimize the blends of wheat and flour
  • Adapt the flour for its final use by accurately measuringout additives and improvers
  • Control the different flour fractions
  • Use on durum wheat (Triticum durum): semolina protocol (standard UNI 10453)


The Alveograph test consists of producing a test piece of dough, which, under air pressure, turns into a bubble.
This process reproduces the deformation of the dough when subject to carbon dioxide during fermentation.

The test involves 4 main steps:

  1. Mixing our and salted water
  2. Preparing five calibrated pieces of dough
  3. Putting these pieces of dough to rest
  4. Automatically infl ating each piece of dough until the resulting bubble bursts

Compliant with:

Results from the AlveoLAB conform to standards AACC 54-30, AACC 54-50, ICC 121, ICC 171, NF-EN-ISO 27971, GOST 51415-99, GB/T 14614, 4-2005.

AlveoLAB benefits


Cooling is assured by an integrated system (Peltier effect). Therefore, there is no need to connect the equipment to a cooling water system.

Dough hydration

At the beginning of the test, water is added automatically and very precisely.
The temperature of the water tank is regulated.

Inflation of the dough pieces

The positioning and the in ation of the dough pieces are automated, and carried out in a temperature and humidity controlled compartment.

The inverted bubble is more spherical and closer to the ideal conditions of the test.


New parameters, stress/strain and first derivative, are now calculated automatically.

“Degradation”, “relaxation” and “hybrid” protocols (a combination of different protocols, for example: alveo + relaxation) are pre-loaded in the software.

Custom protocols can be created, for example, by varying the intensity and duration of the mixing. Consequently, the Alveograph test has even more predictive analysis of our performances.
