In the context of modern food production-particularly in the bakery, pastry and professional pizzeria sectors-the temperature of the sourdough starter is one of the most decisive variables for the success of the process.
This is not an ancillary value, but a central technical parameter, on which the microbiological stability, fermentation regularity and, consequently, the replicability of the finished product depend.

During periods of climatic stress such as summer, where ambient temperatures far exceed 30°C, maintaining controlled and constant thermal conditions becomes not only complex, but essential to ensure continuity of production and consistency in quality.

Thermal constancy: a technical requirement, not an option

The temperature of the sourdough directly affects the metabolism of the microbial flora: excess temperature accelerates acid production, compromises the balance between acetic and lactic acid bacteria, alters the pH, and can lead to hyperacidification or, conversely, fermentation arrest.

For this reason, any uncontrolled change in temperature, even in the order of a few degrees, can result in:

• fluctuations in rising time

• inconsistent aroma profiles

• Changes in the texture and structure of the dough

• Loss of shelf life and digestibility of the finished product

In this operational context, the only really effective solution is the automation and timely control of the thermal parameter, starting from the stage of activation of the sourdough starter to its storage.

MAMA: integrated sourdough temperature management

MAMA is the professional fermenter for liquid sourdough developed by Domino with a clear objective: to ensure complete and continuous temperature control of sourdough, at all stages of operation.

Through an integrated system of high-precision sensors, thermal regulation software and stainless steel mechanical components with active insulation, MAMA automatically manages:

• The initial mixing of flour with water

• The controlled fermentation (maturation) at a set temperature

• The storage of liquid sourdough up to 72 hours, with the possibility of immediate activation

Temperature regulation occurs on the product, not on the environment: the system reacts dynamically to any changes, keeping the sourdough starter in optimal condition, even in non-air-conditioned environments or with significant temperature changes.

Temperature of sourdough starter: Technological advantages in production stage

The use of a fermenter such as MAMA allows for zero thermal fluctuations in the management of sourdough, ensuring:

• Microbiological uniformity between production runs

• Standardization of fermentation behavior

• Stability of pH and yeast strength

• consistent flavor profile

• Significant reduction in the risk of human error

• optimization of manpower and work time

In particular, during the warm season, MAMA proves to be a strategic tool for preserving the fermentation integrity of the sourdough starter, preventing overfermentation or collapse of the bacterial flora.

A scalable and interconnected system for sourdough temperature management

Available in various models (from 15 to 300 liters), MAMA is designed to adapt to production settings of different scales, from artisanal production to large laboratories.
TOUCH models offer:

• Digital phase management with touch screen display

• Regulation of thermal gradients for controlled raising/lowering of temperature

• Interior LED lighting, removable utensils, sanitizable stainless faucets

• 5.0 ready functionality, with the ability to interconnect to production systems and remote diagnostics

These elements make MAMA not only a fermenter, but a strategic node in process quality management.

Concrete application perspectives

Maintaining a constant temperature of the sourdough starter is now an essential technical requirement for those working in the bakery and pastry industry with professional logic.
In the absence of stable thermal management, every other aspect of the production process risks losing consistency, effectiveness and reliability.

With MAMA, Domino provides professionals with a technology developed to automate, standardize and enhance each stage of liquid sourdough fermentation, offering a concrete answer to the need for continuous, replicable and quality-consistent production, even under critical environmental conditions.
