How to control food traceability

What is food traceability?

European regulations define the term traceability as “the ability to find and trace through all production stages, processing and distribution food, feed, food-producing animal or substance intended to be incorporated into food or feed and likely to be incorporated into food or feed”.

What is the purpose of food traceability?

The purpose of product traceability is to be able to trace any food product or raw material within the supply chain and minimize health risks. This is achieved by identifying the batch number, allowing it to be discarded if it poses a safety risk for consumption.

In addition, since 2005, food traceability has been mandatory for companies in the food sector within the European Union.

What are the requirements for food traceability?

The European Union specifies the following 8 traceability requirements (in article 3 of the report published in 2011).

  1. An accurate description of the food.
  2. The volume or quantity of the food.
  3. The name and address of the food business operator from which the food has been dispatched.
  4. The name and address of the distributor if it is not the same as that of the food business operator since the food was dispatched.
  5. The name and address of the food business operator to which the food is dispatched.
  6. The name and address of the consignee (owner) if different from that of the food business operator to which the food is dispatched.
  7. A reference identifying the batch.
  8. Date of dispatch.

What types of traceability should we control?

There are 3 types of traceability that we must control:

Forward traceability

In this phase, all products ready to be shipped are controlled, as well as their recipients.

Process traceability

This traceability refers to the different processes or treatments that the food has undergone between arriving at the company and being shipped.

Backward traceability

This traceability refers to the producer, but in this case of raw materials.

Who is responsible for ensuring food traceability?

The actors involved in the supply chain

The actors involved along the supply chain are responsible for ensuring food safety.

The different states of the European Union

They must put in place different systems of official controls and carry out inspections to ensure food safety throughout the different stages of production, processing, and distribution.

In this area we find for example the HACCP control (Hazard Analysis and Critical Control Points). This is a tool for assessing hazards and establishing control systems that focuses on prevention rather than relying primarily on end-product testing.

The European Union

The European Union regulates quality and safety standards, as well as coordinating actions between the authorities of the Member States where appropriate. It can also impose limits on imports and exports.

It is also who approves the legislation on food traceability that Member States must comply with.

How to make a traceability plan in 5 steps?

Lets get into the 5 steps to establish a traceability plan:

Define product grouping criteria

When establishing a traceability plan, it is important to specify the criteria to be followed to group foods or products. Generally, they are grouped in batches, so that the different groupings of food are labeled with a batch number.

The size of the batch grouping varies according to the criteria previously established in the traceability plan. The more precise the grouping in terms of date, time and machinery used, the smaller the amount of product to be recalled if a health risk is identified.

Create a system of records and documentation

Once the criteria to be followed have been established, it is necessary to implement a system that allows all the data to be collected and recorded in an orderly and automatic manner. For this purpose, batches are usually labeled with barcodes or RFID technology.

The most used codes in the food industry are EAN 13 and EAN 128.

Use of the identification system

All agents in the chain must have an identification system in the three stages of traceability mentioned above, including the batch number on labels, delivery notes and invoices.

Incident control and management

The main objective of this traceability plan is to be able to identify and withdraw all those batches that pose a risk to consumer health; therefore, it must include an action protocol that allows to do it in the most agile, efficient, and safe way.

Test the traceability plan

Finally, the plan must be checked to ensure that it works. This should be done by external people or agents through a system of review and monitoring of all activities.

How to control food traceability with the JANBY Track?

The QR labels of our Janby system in addition to auto configure the cooking equipment for the correct cooking of the products have the following information:

  • Batch identifier
  • Unique bag identifier
  • Organization identifier
  • Discard date
  • Packaging date
  • Information about the manufacturing process
  • Allergen information
  • Information about recommended diets

All this information can be visible on the label or by scanning the QR code we could make visible all the relevant information for the different sanitary audits.

The digitalization of the Sous-Vide process

What is the Sous-Vide technique?

Sous-vide is a culinary technique that maintains the integrity of food by heating it for long periods of time at relatively low temperatures.

The Sous-Vide process

The Sous-Vide process consists of placing raw or pre-cooked food in a watertight and heat-resistant container, extracting the air from inside, sealing it hermetically and subjecting it to the action of heat at a constant temperature and for the necessary time. The containers used for this technique are generally made of complex plastics that provide resistance to high temperatures, low oxygen permeability and protection against manipulation. This process enables assembly cooking as it keeps cooked dishes in stock for long periods of time.

Vacuum packaging

Vacuum packaging is a natural food preservation technique that consists of extracting the air from the enclosure, eliminating oxygen, the main factor in food spoilage.

The main qualities of sous vide cooking are that by heat treating the food in an airtight and airless enclosure, nutrients and aromas are retained to the maximum, the oxidation of the ingredients is avoided and weight loss and desiccation due to evaporation are reduced.

Vacuum cooking

Cooking is carried out in a humid environment at moderate temperatures ranging between 65ºC and 95ºC depending on the type of product and takes place for generally longer times than those used in traditional cooking.

Rapid blast chilling or deep freezing

Deep freezing makes it possible to reach a temperature of -18ºC in the core of the product in less than 4 hours for its subsequent storage under optimal conditions of conservation. The rapid lowering of the temperature allows the maintenance of a large part of the moisture contained in the food and prevents the formation of macro-crystals, so that the organoleptic properties of the food are preserved.


Finally, this product is rethermed before serving. In this phase of the process, we use the sous vide cooker again to retherm the product before the final touch and serving. It is very important that the retherming temperature does not exceed the initial sous vide cooking temperature at the heart of the product.

Benefits of the Sous-vide method

This technique brings numerous benefits:

  • It maximizes the organoleptic properties of the product, since cooking is carried out in hermetically sealed containers, thus preserving flavors, textures, aromas, and color.
  • Healthy: since it allows to preserve all the nutrients and requires less additives.
  • It favors food safety as it avoids cross contamination.
  • Improves shelf life of products thanks to its rapid cooling and preservation process, minimizing food waste.
  • It allows more planning and advance preparation, consequence of the assembly kitchen.
  • It favors consistent results which are acquired by standardizing parameters such as time and temperature.

The digitalization of the Sous-vide process

The emergence of the foodtech industry and the kitchen digitalization have also made their way on the Sous-Vide process.

In this context, the JANBY Track is born, a system that digitizes and automates the sous-vide cooking and retherming process, providing greater standardization of both the product and the process, as well as greater control.

Elements of the JANBY Track

The system is made up of the following elements:

Tablet Janby Box: a specific tablet that contains the software and a series of connectivity.

JANBY Tag: these are labels used to identify the different bags that share the same water tank.

Smart label: it is a label that carries information about the printing date, expiration date, batch, ingredients and, most importantly, the product’s elaboration process that, as we have seen previously, follows two parameters (time and temperature).

JANBY Cloud: is the platform where all the information about the different equipment, products, recipes, kitchen processes and different establishments of the same organization is centralized.

Sous-Vide equipment: currently the system it is only capable of communicating with SAMMIC’s SmartVide cookers.

The JANBY Track step by step


Benefits of the JANBY Track system

The JANBY Track system answers the main concerns when several individual servings are cooking in the same water tank:

– Which bag was introduced first?

– How do you control the different cooking times for each of the portions?

– How do you identify portions for customers with special dietary needs?

– How do you keep a history of those you have cooked?

In addition, it provides us with an exhaustive traceability of temperature and time data, compatible with HACCP control.

Traceability: the system maintains the history of what is cooked, portion by portion, allowing subsequent monitoring of the cycles carried out. Individualized monitoring allows to quickly identify and track special customer needs, such as allergens, salt-free diets, etc. Plus, through smart labels and the integration to different POS systems, it is possible to obtain a complete traceability of the food chain.

HACCP control: JANBY Track generates very precise reports of cooking times and temperatures, portion by portion, allowing a complete and precise traceability from different devices at all times.

JANBY Cloud: the cloud environment centralizes all the data of each organization and equipment providing unprecedented control over the operations that take place in the kitchen.

Business case: Bidfood NL and Kitchen Create

Bidfood Netherlands

BIdfoodnl is one of the leading hospitality distribution companies in the Netherlands. They offer a wide product portfolio and almost immediate delivery times that make them strong players in the foodservice field. They differentiate themselves from the competitors by offering additional services to their clients in terms of consultancies, trainings, and demos, which are perceived by the client as high added value services.

The SmartVide food range and Jordy´s Keuken

The difficulty for finding Chefs in the Netherlands, stressed by the COVID situation, has accelerated the development of technological solutions, as well as the offer of quality mise-en-place food that is easy to cook.

Within their catalog of Jordy’s keuken they offer all the necessary elements to make a dish, as well as a SV range. The SV range consists of vacuum-packed products designed to be regenerated by immersion which now also carry Janby’s QR labels. The labels have embedded all the information about the product and, most importantly, its retherming or cooking process. This range of products can be regenerated using the Sammic SmartVides together with the Janby Track for a completely unattended and automated regeneration process, significantly reducing the needs of a qualified Chef in the kitchen.

How can I get the Janby Track license in the Netherlands?

In the Netherlands we work with our partner Kitchen Create. Kitchen Create is a company specialized in custom made professional kitchen solutions for the hospitality industry. In addition to selling Sammic SmartVides, is also a Janby partner and point of contact in the Netherlands.

Restaurants already using the system in the netherlands

After the launch of the system at the Gastvrij Rotterdam show in September 2021, Kitchen Create has installed the system at 3 facilities so far:

Gastrobar Hartig


Brasserie Barclay

This is a clear example of how food manufacturers can benefit from the system not only through the traceability of their products, but also by offering an added value to the customer with a system that ensures product quality while reducing the need of chefs.

Business case: Foodit Ibiza

What is Foodit Ibiza? 

Foodit Catering Ibiza was corn from a passion for food, which they believe to be an expression of their culture and life. Good cuisine, whether it is Mediterranean, Asian or Vegetarian, makes each of their events unique.

To achieve so, they count on a team of chefs that hold the internationally recognized STCW95 certificate. Also, after years in the business, they have a great notoriety and a wide net of partners that strengthens them as a leading catering company.

What makes them go into the readt to eat food production business?

The COVID-19 crisis has brought new consumption trends that have accelerated the business innovations and the urge to diversify.

Foodit is no exception to it, as they have seen in the lack of events and shortage of qualified chefs a unique opportunity to diversify and launch their ready to eat food products for the restaurant industry.

The high rents and the marked seasonality of the island makes it difficult to find qualified chefs who want to stay in the same restaurant for long periods of time.

After identifying this problem, they took advantage of the synergies of their catering business in which it already had chefs and recognition within the island, to offer its products to the different restaurants that face this problem.

What is their value proposition

In addition to a range of hot dishes and gourmet pastries of the highest quality, they offer the JANBY Track system that allows them to encode the regeneration process of the different products to ensure their correct retherming.

In words of the founder, Salvatore Teodoro ¨ An elaboration of the highest quality is useless without the optimum retherming¨, and this is what they are trying to ensure with the JANBY Track.

The client of Foodit only needs a PRO license to scan the QR codes that go into each product and automate the retherming process as they reduce the dependency on the chef.

Moreover, thanks to the discard batch function that the JANBY Cloud offers, contaminated food can be easily discarded form the production centre, as well as keep control of their clients needs.


Their first client is Es tancó, an italian restaurant located in he area of Sant Rafel.

The COVID crisis and the restrictions that have been applied in the restaurant industry has led them to look into different solutions that require less qualified personnel and that allow them to reduce food waste. To do so, they lean on Foodit and their 5th range products togetehr with the JANBY Track. With the JANBY Track they ensure that the retherming of the products is done preserving the quality as per the origin.

So, in addition to their traditional dishes, we can also find: polenta with vegetables cooked at low temperature, a risotto with grana and truffle, low-temperature pork ribs and low-temperature pork knuckle.

Some of their products 

Below some of the products of their 5th range carte:

Food safety when cooking at low temperatures

Is it save to serve chicken cooked at 63ºC?

When first discovering the Sous-Vide cooking technique, is relatively common to question yourself wether it is safe to cook chicken at 63ºC. In this article we want to analyze in detail the cooking process at low temperatures, not only form the classic Time/Temperature table stand point, but we want to understand where these tables came from.

What is the Sous-Vide cooking technique?

First of all, we have the culinary technique that consist on cooking at low temperatures and on the other hand we have the Sous-Vide technique, which consists in isolating a product in a waterproof sealed container from which the air has been extracted. This air extraction can be done for various reasons such as, product conservation, to cook the product, to infusionate or marinate. What we commonly know as Sous-Vide cooking is the combination of Sous-Vide and the low temperature cooking process. This differentiation may sound confusing at first, but it is crucial to understand what we will be trying to cover in this article, how to ensure food safety while Sous-vide cooking. And to make the long story short, we will refer to it as Sous-vide.

Sous-Vide cooking is a combination of two paramettres: time and temperature. The fact that the cooking is done in waterproof and hermetically sealed bags enables to preserve all aromas and flavours. Moreover, because the cooking is done at low temperatures all nutrients will be preserved at the same time as we obtain textures that would be impossible with the traditional cooking method. But, how can we ensure a safe preparation?

How can I get a safe output when cooking at low temperatures?

According to the OMS, the salmonella(no tifoidea) is in the top 4 cause for illnesses related to diarrhea in the word. Even in the UE, where the effect is much lower compared to other regions, 92.649 cases where reported in 2017. Salmonella is a bacterial pathogen that can be found in the majority of meat or poultry. This makes it crucial to apply lethality treatments to those products before serving. Lethality is the process or combination of processes that ensures a specific, significant reduction on the number of Salmonella and other pathogens in the product.

We are talking about a significant and specific reduction raher than of a complete elimination of the pathogenic agents, which would be called sterilization. The objective is that in case the product has been polluted with pathogenic agents, these are eliminated enough so that the consumption of the product is safe. This process will also imply that the shelf life of the product will depend of the process carried out after as the conditions in which is stored.

When Sous-vide cooking this lethality process consists on applying heat and is the one we are focusing on in this post. However, we have to mention that there other lethlty treatments such as: drying, fermentation, salt curting high pressures…

The reason why the lethality objectives are centered in Salmonella is because it is the more resistent in the cooking processes among the comon ones. It has also been found that acommon cause for Salmonella outbreaks is the insufficient cooking of the product. On the contrary, in the post-lethality and stabilization treatments it is more common to focus on listeria (post-lethality) and toxins derivated from sporeforming bacterias like Clostridium perfringens and botulinum (Stabilization).

What is the pasteurization?

The US Food Safety and Inspection Service (FSIS) defines the pasteurization as any process, treatment, or combination thereof, that eliminates or reduces the number of pathogenic microorganisms to achieve at least a 5-log reduction at the end product. Keep calm, and let´s understand what this means. With everything that we have said until now it has become clear that the pasteurization is a lethality process with the objetive of reducing pathogenic agents in a significant and specific way, up to 5-log. You may have the logarithmic scales a little bit forgotten, don´t worry, we are here to explain this. The logarithmic scales are a way of displaying numerical data over a very wide range of values in a compact way. In logarithms with moving a unit of distance along the scale means the number has been multiplied by 10. Understood, so a 2-log reduction implys dividing per 10 twice, which is the equivalent of a 99% reduction (100 -(100/10)/10= 99% ), then 5-log es is a 99.999% reduction.

How to apply the pasteurization when cooking at low temperatures?

So, the definition was very precise but, how we apply this into the everyday operations in the kitchen? Luckyly for us, after several laboraory studies, we have some tables that show different time and temperature combinations that can be used for different products. The above has served to understand where the tables come from, and to understand that any of the time and temperature combinations shown in the tables represents the significant reduction of the pahogenic agents so that the consumption of the product becomes safe. However, we must not mix up these tables with Sous-vide recipes. The time and temperature combination of the tables is intended merely to the reduction of those apathogenic agents, however, the Sous-Vide recipes attend to the texture a given combination of time and temperature is able to provide in order this to be tastiest. So, the right recipe will be the one that can meet both criterias, later on we will show you some tools in order to achieve this.

If you were wondering why each protein has several time and temperature combinations, the answer is very interesting. There is a range of temperatures where pathogenic bacteria can reproduce and proliferate. Even if each microorganism has its own values, temperatures between 5 and 54ºC are considered risky. Above 54ºC microorganisms start to diminish rather than reproduce. However, this doesn´t happen immediately, it is required to maintain the temperature for as long as the tables indicate to reach the pasteurization point. For instance, with chicken, once we reach 73ºC pasteurization happens instantly. Also, if you have a look at the tables, poultry with unknown fat values, have to be kept 13 minutes at 63ºC.

What are the requirements to pasteurize?

So, if those tables existed, why have we always known 73ºC as the safe temperature for cooking? We must say that these tables are recommendations to achieve the sufficient lethalty in order for a product to be safe. But, together with them, there are some additional requirements we should apply in our low temperature cooking process.

Lets have a look:

  • The temperature must be measured at the coldest point of the food we are cooking, which is refered to the internal temperature of the product, not the one of the water.
  • The thermometer must be calibrated and have a 1ºF precision.
  • There must be time registers during the whole process. (With a maximum of 1 minute between measurements)
  • The relative humidity during the cooking process must be controlled. For instance, if we put a piece of meat in the oven into a relatively low temperature, the evaporation process will make the temperature at the surface to descend, and could make it a place for bacteria to resist. Fortunately, when Sous-Vide cooking, as the cooking is done inside hermetically sealed plastic bags, evaporation doesnt happen, so we don´t need to measure humidity.

When Sous-Vide cooking, as this is done via immersion, a foam is used between the plastic and the probe to avoid the air and water to get in contact with the food.

All the above was simplified into the before shown tables, as the values on these tables provide immediate pasteurization, which may spread the idea that all the rest were dangerous.

Which Sous-vide equipment is focused in HCCP?

Nowadays, and thanks to the Sous-Vide equipment of manufacturers like Sammic, we are able to measure the temperature at the heart of the product and to generate several records to certify that the elaboration of a given product has been safely carried out. But not only this, at Janby we wanted to contribute to the digitalization of the Sous-vide process so we have developed a registered software that automatically not only checks the process in real time, but emits notifications when pasteurization is achieved. In this way, we could set the Time and Temperature parameters that meet our texture criteria and the Janby Track will concurrently check the pasteurization tables for the given product. If the Track identifies that the product is not pasteurized this will keep it in the water until is met. Also, if for any reason the water temperature descends half way the cycle, Janby Track will reset the pasteurization times to ensure and optimize the process.

How to ensure food safety with the JANBY Track?

Janby Digital Kitchen is born to digitalize the processes in the kitchen and with its first product, the Janby Track, it digitalizes the Sous-vide process. The Janby Track, has some Active Controls that among other things take care of the pasteurization. As its name indicates, these controls work actively throughout the elaboration of a product and ensure that additional parameters to Time and Temperature are met. There are 4 of them that are focused in the pasteurization and each organization can choose which one to use according to their HACCP requirements, which may vary from industry and from country.

1. Product pasteurization control: The probe pasteurization control monitors the temperature at the heart of the product throughout the whole process and ensures the compliance of the selected sanitary regulation. Once the recipe time is concluded, this control analyzes if the accumulated time and temperature meet the regulation. If the regulation is met, the Track will put the product ready to extract, if not, the Track will maintain it cooking until this is met.

2.Continious probe monitorization: The probe control monitors the temperature at the heart of the product continiously and acts accordingly. To set this continious probe control you need to establish a minimum probe temperature to be monitored throughout the whole elaboration process. If for any reason, the temperature at the heart of the product goes below the established temperature, the recipe will be restarted.

3. Final probe measurement: the final probe measurement control makes sure that the temperature at the hear of the product once the elaboration is completed is the one the user has set. In order to do so, the operator must introduce the probe at the end of each elaboraion.

4. Continious water monitorization: The water control monitors the water tempeature continiously and acts accordingly. To set this continious water control you need to establish a minimum water temperature to be monitored throughout the whole elaboration process. If for any reason, the temperature of the water goes below the established temperature, the recipe will be restarted.

Find below the link to the official report carried out by the FSIS about the food safety measures to follow for Salmonella. The document is specifically targetd to the RTE (Ready to Eat) industry. So, some parts may not necessarily be aplicable to the restaurant industry. However, the pasteurization tables and explanations regarding lethality are valid in any context.
