Temperature control in the catering industry - what do you need to look out for?
The catering industry requires operators to comply with important regulations on a daily basis to ensure the safe operation of their own restaurant and to maintain satisfied customers. In addition to complying with hygiene and safety regulations, these requirements and regulations include the regular monitoring and documentation of temperature values of stored food and prepared dishes. In this article, you will find out what you as a caterer need to pay attention to when storing food that requires refrigeration and how modern technology can help you with this.
Why do temperature data need to be recorded?
To ensure the safe consumption of food and prepared dishes, caterers are obliged to comply with various guidelines and standards. These include, for example DIN 10508, which describes discrete temperature ranges for each type of food in the case of storage, or the EU Regulation 178/2002, which regulates the mandatory traceability of supply chains in the catering sector.
To ensure legal compliance, catering establishments must regularly check the temperatures of stored food and served dishes. This documents that the food offered to customers is fresh enough to be consumed safely, which in turn leads to greater customer satisfaction.
How can the required measurement data be collected?
The recording of temperature data in the kitchen and storage rooms can be done manually to fulfil the above-mentioned requirements. on a printed and later filed List can be made. However, as an alternative to a physical list, a Digital recording and forwarding of temperature data can be set up.
When documenting the data, a regular interval between the observation times and a clear link to the measured food or cold store must be ensured. The more varied the number of different foodstuffs and storage locations, the more worthwhile it is to purchase a digital/automated solution for recording measurement data. In this way, all relevant information can be measured simultaneously several times a day, which cannot be done in the same way manually.
What measuring equipment can be used for data collection?
Various measuring devices are available for reliable temperature documentation in the catering industry - from analogue devices to modern IoT-Solutions. Classic thermometers or infrared guns are often used manually, but require regular checks and careful logging. Digital data loggers offer automated recording and can store temperature curves over defined periods of time. Networked wireless sensors that record measurement data in real time and transmit it directly to a central cloud are particularly efficient. They significantly reduce personnel costs, minimise sources of error and meet the requirements for complete documentation in accordance with the HACCP standard.
Comparison of manual and automated temperature detection
Regular manual spot checks of stored food and prepared dishes are mandatory and good practice if carried out carefully, but they mean additional labour, paperwork and a source of human error.
Continuously measuring sensors, on the other hand, can independently recognise temperature trends and automatically trigger alarms if limit values are exceeded in order to save potentially endangered food. In addition, they relieve employees of the task of checking the cold store and remain active and vigilant even on non-operational days.
With a clear overview at all times of the current and past temperatures of food to be used and finished dishes, customer safety and satisfaction can be increased and the unnecessary disposal of food can be reduced.
To summarise, the most important features of temperature monitoring for the manual and automated approach can be compared in the following table:
| Feature | Manual documentation | Automated recording |
| Precision | Prone to human error, depending on the implementation | Precise, Comparable, Reliable |
| Scalability | Limited expansion possible with the same number of employees | Can be extended or reduced as required |
| Costs | Low | Initially higher, amortising over time |
| Technical effort | Low | Initially associated with the creation of an infrastructure, later only to be controlled |
| Measuring point density | Limited, depending on measuring points to be tested and number of personnel to be tested | High density, almost complete documentation possible |
| Reaction time | Depending on measuring equipment quality and measuring intervals | Independent trend detection and alarm when limit values are exceeded |
Conclusion
Temperature monitoring is not only required by law in the catering industry, but is also key to food safety and guest satisfaction. While manual documentation involves a great deal of effort and is prone to errors, digital, automated systems provide a reliable, seamless and efficient solution. Modern sensor technology helps to recognise risks at an early stage, conserve resources and make day-to-day work noticeably easier.
