FOOD
In a continuously innovating sector, the active packaging lengthens the conservation of food and allows the control of the products.
The introduction of products that improve conservation or control of the food chain is currently one of the areas of innovation in the food industry. Active packaging is already a reality that will gradually become a standard to offer customers more durable products in a protective atmosphere. On the other hand, the information during the supply chain collected with indicators facilitates the identification of deteriorate products during the process.
At the moment all this type of products are supplied in small labels or bags that are introduced inside the containers, although the modified containers themselves are already appearing without additional elements.
At Sercalia we have all kinds of specialised products for food preservation: moisture, oxygen and ethylene absorbers, temperature and humidity indicators, moisture stabilisers, isothermal products for the cold chain, aluminium bags and films and natural zeolite.
Moisture absorbents
Many food products when packaged may become deteriorated due to moisture remaining inside the containers. The introduction of desiccants allow solving the problem leaving the food in perfect conditions, without moisture.
We have other specialised moisture absorbers such as: Silica Gel, Desiccant Clay, Eco-sustainable Desiccant, Molecular Sieve, Desiccant Cartridges, Desiccant Plugs, Moisture Absorbent Blanket, Desiccant Tablets and Pressure valves
Oxygen absorbers
Products such as meat, pasta, backery, bulk or cooked products and nuts are spoiled by environmental oxygen. Removing oxygen from the inside of the containers allow life of these foods to be extended.
Oxygen absorbers available: Ageless Bags, Ageless Omac Film, PharmaKeep (Oxygen and Moisture Absorber) RP System and AnaeroPack
Ethylene absorbers
Fruits, vegetables and flowers release ethylene when they ripen, and if ethylene remains in the container, the ripening of the product is further accelerated. With the ethylene absorbers it is possible to lower the rippening rate of food, thus extending its useful life.
Absorb ethylene with: Ethylene Absorbent Bags, Ethylene Filter, Ethylene Pad, Ethylene Control System, Ethylene Absorbent Sheets for Household Use.
Temperature Indicators
During the food supply chain the temperature value of the environment where it is, may be critical for its good conservation. Thanks to the temperature indicators we can control that the temperature of the product is maintained at certain values.
Humidity Indicators
Humidity indicators allow to control the range of humidity in which a product is maintained to allow a better conservation of the product until it reaches the consumer. They are introduced in the package being able to see from the outside the internal humidity.
Reversible and irreversible moisture indicators are available.
Moisture Stabilizers
A new product that allows to keep food at a constant humidity during the storage and transport phases, to ensure that the product is maintained at the same relative humidity and not lose properties.
Moisture stabilisers in different formats and sizes available: Propadyn Museart, Propadyn Industry, Prosorb, Artsorb
Cold Chain
Products to keep the cold chain intact: isothermal insulation, cold accumulators (rigid, flexible, hydratable, and eutectic), freezer accumulators and thermal barrier, eco isothermal kit, thermal boxes, thermal containers and isothermal backpacks, isothermal bags and pallets, isothermal bags and pouches and cooler bags. temperature indicators. Ensure your products have been kept within a safe temperature range throughout your supply chain.
Aluminum Bags and Film
The best packaging material to conserve in perfect state food is the aluminum. It does not allow through light or oxygen to have a minimum permeability, offering the best guarantee for the good condition of the product when reaching the consumer.
We offer aluminium bags in different sizes and finishes: zip bags, kraft bags, gusseted bags, flat bags. Metallised and laminated.
Natural Zeolite
Natural zeolite is a naturally occurring zeolite used as a moisture adsorbent and other molecules in agriculture, swimming pools, water treatment, filtration and other applications in an ecological way.
FAQs
Food preservation: answers to the food industry’s most frequently asked questions
What factors can affect food preservation during storage and transport?
Humidity, oxygen, ethylene and temperature are some of the factors that can affect food during packaging, storage and transport. Their importance depends on the type of food, the packaging used and the conditions throughout the supply chain.
The preservation strategy should therefore be based on the specific risk that needs to be controlled. Depending on the application, humidity, oxygen or ethylene absorption systems, temperature control solutions and devices for monitoring specific conditions during storage or transport can be used.
When should a desiccant be used and when should a humidity indicator be used?
A desiccant and a humidity indicator perform different functions. A desiccant acts on the moisture present inside packaging or a container, while an indicator provides visual monitoring of specific humidity conditions.
The choice therefore depends on whether the aim is to protect the product against moisture, monitor conditions or perform both functions. In certain applications, they can be used together, provided that the characteristics of the food, packaging and storage or transport conditions allow it.
How do you choose an oxygen absorber for packaged food?
The selection should take into account the characteristics of the food and packaging, as well as the volume and conditions of the application. The amount of oxygen that needs to be absorbed and the permeability of the packaging material must also be considered.
Oxygen absorbers are designed to reduce the presence of oxygen in sealed packaging and can be used in a range of food applications. Sercalia offers different solutions and formats, so each application should be assessed to select the appropriate system.
Why is it important to control ethylene during the preservation of fruit and vegetables?
Ethylene plays a role in the ripening process of fruit and vegetables. When it accumulates around the product after harvesting, it can encourage the ripening process to continue.
Ethylene absorption and control systems can help manage its presence during specific stages of preservation, storage and transport. The solution should be selected taking into account factors such as the type of product, packaging, volume and conditions throughout the logistics chain.
How can food be protected during temperature-controlled transport?
temperature, the volume being transported, the duration of the journey and external conditions.
Solutions for these applications include cold packs, insulated boxes and containers, bags, pouches and other insulation systems. These elements can be complemented by temperature monitoring devices to provide information on the conditions experienced by the product during transport.
What is the difference between protecting and monitoring food during transport?
Protection and monitoring are complementary but different functions. Protection solutions act on the conditions surrounding the food: for example, by controlling humidity, reducing the presence of oxygen or ethylene, or helping to maintain specific temperature conditions.
Monitoring solutions, such as indicators or data loggers, make it possible to detect or record specific conditions to which the product has been exposed.
Monitoring a variable does not in itself protect the food against it, but it provides useful information for controlling the logistics chain.
When should a temperature indicator be used and when should a data logger be used?
When should a temperature indicator be used and when should a data logger be used?
Can different food preservation solutions be combined?
Yes, a single application may involve several risks and require more than one protection or monitoring strategy. For example, a solution designed to control specific environmental conditions can be complemented by an indicator or data logger that provides information about the conditions experienced during distribution.
The appropriate combination will always depend on the food, the type of packaging, environmental conditions, storage time, transport duration and the requirements of the application. There is therefore no universal combination suitable for all food products.
How do I choose a protection and preservation solution, and how can Sercalia help me?
The starting point is to identify which risks may affect the food and at what stage of the supply chain they occur. Factors such as humidity, oxygen, ethylene or temperature require different solutions and, in certain applications, it may be necessary to address more than one.
The type of food, packaging, environmental conditions, and storage and transport characteristics should also be considered.
At Sercalia, we provide technical advice to analyse these variables, identify the risks and help you select the most suitable protection or monitoring solutions for each application, combining different technologies when necessary.
