CO2 yeast raising power in dough


Affordable and accurate yeast performance testing for baking and yeast industry

What can YeastForce do for you?

YeastForce is for determination of raising power 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.

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

Developed in cooperation with VH Berlin

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.
