Cold link definition ❄️

We speak of cold link when the place of production is different from the place of consumption and the delivery between the 2 sites is made at temperature < 3 °C.

The HACCP method is applied very rigorously in collective catering to ensure food safety. Central kitchens favor cold chain processing.

What are the different stages of the “liaison froide” process?

schéma liaison froide
During transport in refrigerated trucks or insulated containers, the product is kept at a temperature < 3°C. Upon receipt at the satellite site, storage is done in a cold room < 3 °C. ❄️
✏️ Example: For example, grated carrots or cooked ham. It is then produced cold and stored in a cold room at a temperature < 3 °C. Then, transport is carried out in a refrigerated truck or insulated container between 0 °C and 3 °C. Upon receipt at the consumption site, storage is done in a cold room < 3 °C ❄️. Finally, the product is served cold.

Cold link regulations: what does the law say?⚖️

What does the law say? ⚖️ The decree of December 21, 2009 states that “precooked dishes prepared in advance must be stored or transported at a temperature of 3°C. Similarly, the storage temperature in collective catering establishments must also be a maximum of 3°C.”

You can download the Good Hygiene Practices Guide (GBPH) for Home Meal Delivery.

The HACCP method requires respecting the temperature range for rapid cooling for several reasons:

  • Hygiene 🧼: the risk of microbial growth 🦠 is very high between 63°C and 10°C. Pathogenic bacteria are destroyed above 63°C, while below 10°C, their growth is stopped. Too slow cooling therefore increases the risk of contamination. ⚠️
  • Organoleptic quality 🍽️: rapid cooling better preserves flavors, texture, and limits evaporation or oxidation. This is essential in pastry making for mousses, glazes 🍰, and gelling agents.

Cold and Hot Chain: What Records to Keep for Compliance? ✅

You must record all food temperatures at each stage of processing, as well as at the start and end of delivery.

🔥 Hot Chain

In collective catering, the hot chain involves keeping food at a high temperature to ensure food safety. It is recommended to record:

  • End-of-preparation temperatures (for cooking): the dish temperature must reach at least 63°C.
  • Records before shipment and upon arrival:
    • At departure ➡: product name, product temperature (≥63°C), quantity, departure time.
    • At arrival ⬅: product name, product temperature (≥63°C), quantity, reception time.

❄️ Cold Chain: Temperature Monitoring

The cold chain consists of rapidly cooling food before storage and transport. The recommended records are:

  • Cooling down records:
    • Product name, time and temperature when placed in the cooling chamber.
    • End time and temperature: the drop from 63°C to 10°C must happen within less than 2 hours.
  • Transport records:
    • At departure ➡: product name, product temperature (≤3°C), quantity, departure time.
    • At arrival ⬅: product name, product temperature (≤3°C), quantity, reception time.

Digitize your records for better traceability! The Octopus HACCP app allows you to monitor the temperature of your preparations at every stage of production and during delivery.

These control dishes are representative samples of the different dishes distributed? to consumers and clearly identified. They must be kept for at least five days in positive refrigeration (0-3°C) after the last presentation to the consumer.

 

Please note: for hot and cold service, it’s important to keep control dishes on hand. In the event of a CFTI, the control dishes will be analyzed to detect the origin of the infection.

What is the protocol for reheating in the cold chain? 🔥❄️

Upon receipt of a product in the cold chain at a satellite site, you must ensure the conformity of the reception. The elements to record are: product name, quantity, temperature 🌡️, and reception time.

Storage 🧊: any product received in the cold chain must then be stored at a temperature below 3 °C.

Reheating must be done quickly to reach 63 °C within one hour. It is therefore recommended to record the product name, start time and temperature, then the end time and temperature.

Ensure Food Safety During Your Deliveries

The Octopus HACCP app allows you to easily track your products at all your delivery points. 🐙

Record them at the central kitchen departure, and your satellite sites only need to validate the temperature 🥶 upon receipt.

The Octopus HACCP app is used by many organizations and supports them daily.

What is Hot Chain (Liaison Chaude)?

The hot chain refers to all hot food productions delivered with the temperature maintained above 63 °C. 🔥

Thus, from the end of production, through storage and delivery, until service, the temperature remains > 63 °C. That is why hot chains involve short transport times, mainly for retirement homes. This is also called home delivery. 🏠 However, central kitchens can also deliver to nearby satellite sites such as schools.

What are the different stages of the “liaison chaude” process?

schéma liaison chaude
✏️ Example: If the product is intended to be consumed hot 🔥: for example, a gratin dauphinois. It is cooked, and the final cooking temperature must be > 63 °C. Then, the gratin is cooled in a blast chiller (temperature drops from > 63 °C to a maximum of 10 °C in less than 2 hours). After rapid cooling, it is stored in a cold room at < 3 °C.

Hot link regulation: what does the law say? ⚖️

What does the law say? ⚖️ As with cold chain logistics, hot chain logistics are regulated by the decree of December 21, 2009, which states that “the minimum temperature for hot chain dishes or meals delivered hot or served to the consumer is 63 °C.

Food products must be transported in insulated vehicles that ensure maintenance of the temperature at +63 °C (decree n°2007-1791).

Product Shelf Life: What Does the Law Say?

What does the law say? ⚖️: “The shelf life of prepared culinary products made in advance is determined by the operator. However, the shelf life of refrigerated prepared culinary products made in advance cannot exceed three days after the day of preparation, in the absence of specific shelf life studies. On one of the external faces of each packaging of the prepared culinary products made in advance, at least the use-by date must be indicated.

For unpackaged products then repackaged, the use-by date cannot exceed the initial shelf life of the product or the component with the shortest shelf life.
