CO2 yeast raising power in dough

YeastForce

Affordable and accurate yeast performance testing for baking and yeast industry

Dough volume, gas retention and total gas volume in only one measurement

YeastForce is for determination of raising power, dough volume, gas retention and total gas volume in dough pieces (or sugar solutions) as CO2 pressure measurements [mbar] over time (usually 2 hours). This method correlates very well with the accredited association methods of VH Berlin - Research Institute for Baker's yeast.

Moreover YeastForce can determine the gas holding capacity in doughs of proofing dough samples (with yeast, baking soda or sour dough) as CO2 gas concentration kinetics.

Dough key figures which are important for the baking result, such as proofing time (time to max. fermentation volume of the dough sample) and gas retention (coefficient [%]) gas proportion in the dough, total produced gas can be determined online at any time in just one single measurement.

YeastForce is used in the inspection of incoming goods to determine the quality of the yeast in an easy and quick way. This way you can avoid discarding large quantities of dough. Since the yeasts change during storage, it is recommended to carry out additional tests at appropriate intervals.

We are very pleased with the YeastForce device.  It is easy to use and calibrate.  We like that the system can provide the dough volume and gas retention capability in addition to the total gas produced by the yeast in one measurement.  The software is well designed and easy to use for the laboratory technicians.  We can easily set-up tests templates that prevent errors.  The YeastForce also demonstrated the lowest variability among all the gas measuring devices assessed.  The fact that we can run a simple 1-point calibration with a volume inspection is a key point for us by making sure the precision of the results is optimal.  Finally, BlueSens support was very good during our implementation.

We are very satisfied with the measuring device. Above all, we like the large number of useful measurable parameters such as dough volumes and gas retention capacity very much.
In addition, these are displayed very well and clearly, also graphically. The measurement methodology is sound, and suggestions for improvement and optimization that we suggest are implemented. What we would like to emphasize in particular is the very uncomplicated, direct and fast way in which they respond to our special requirements and wishes and implement them.

We are very satisfied with the new measuring device. We get comparable values compared to our old device and it is much easier to use.

How does YeastForce work?

In determination of quality and productivity of baker’s yeast dough raising capacity is known as the most important quality parameter.

Compact and affordable YeastForce simplifies and accelerates determination of CO2 produced during dough maturation. Sample dough is placed in the sample bottle and closed by putting on the head which contains the sensor. During maturation pressure, temperature and changes in concentration are measured. Even the time of porosity is measurable and can be visualized. After setting all templates and standards (only once), measurements will run automatically with no manual interaction needed. Sensors will measure every second and forward data to the software YeastForce Monitor in a pre-set logging interval. At the end of the measurement, a complete report is created.

Yeast Force:

  • reasonably priced and quick
  • determination of: raising power, dough volume, time of porosity
  • standardized measurements and easy calibration
  • automatic calculations and reports

Technical Short Facts

  • 3 measuring channels: CO2, pressure, temperature
  • measurement principle of CO2 analyzer: infrared
  • accuracy: 0,2% MBE ± 3 % reading
  • measurable gas volume: 0-360ml/h
  • pressure range: 0.8-1.3 bar
  • temperature range: 15-40°C
  • data transfer: RS232
  • dimensions: 162,6 x 224,5 mm

Example Applications

  • Quality control of incoming and outgoing goods
  • Testing new or improved recipes
  • Testing the influences of additives or eg freezing to dough
  • Testing baking poweder or raising agents
  • Check flour qualities
  • determine optimum timepoint to start baking

Setup of YeastForce can be changed according to individual needs. The setup (shown above) can be completed by a water bath and PC.  We will be happy to assist you in finding the right setup.
