Intelligent label for better food

29.04.2014

Two intelligent labels were developed to monitor the time and temperature of frozen products and to monitor the oxygen content in modified atmosphere packed fresh chilled food. The food producer, transporter, retailer and consumer can see with a change of colour of the smart label if the food has been stored at too high temperature and consequently if the food is prematurely spoiled.

Controlling the post production life cycle of food is an important element of food supply chains. Improper handling of product during transport, storage and in households results in quality defects, increases risk of microbial growth, subsequent spoilage and increases wasting of food.


TTI based on an enzymatic reaction inform the consumer about the quality of the products using a green-orange-redlight system.

Previous investigations showed that there are still many unexploited application areas for time-temperature monitoring using smart labels. In the IQ-FRESHLABEL project, novel intelligent labels for indication of temperature abuse of frozen foods were developped.

These smart labels have to meet demands specific to frozen food. Products have very long shelf-life of 18 to 24 months at optimal storage temperature of -18°C. Increase of temperature lead to major quality deterioration, even if temperature stays below 0°C.

“Smart labels for frozen fish products are validated in Greek cold chain and ready to be implemented on the market. It is possible on a unit base to monitor the quality of the food products in terms of respect of the optimal storage temperature along the cold chain – an obvious benefit for the consumer”, says Marie Shrestha, project manager at the independent research institute ttz Bremerhaven.

Leakages in chilled poultry products packed under modified atmosphere lead to change of the gas atmosphere and thus the shelf life of a product is decreased by 26% for example for a leakage with 0.2mm diameter. A novel, cheap and non-destructive quantitative oxygen detection system, using luminescence technology was created to detect leakages in MAP food (detection range 0-30% O2) and inform about subsequent potential premature spoilage of the food product.

The socio-economical impact of the integration of the smart labels in different food chains was studied in Finland, Germany, Southern France, and Greece. Food manufacturers, retailers and consumers see benefit in implementing intelligent labels. Consumers consider that products with TTI are of higher quality than the ones without and are willing to pay 20 cents more for TTIs (n=2525 consumers interviewed).

Participating food, packaging and consumer associations promoted the influence of smart labels application on waste reduction, food quality and safety in the European supply chains in Greece, Finland, Norway, France, Romania and Poland. Consumers considered that TTIs would assist them to handle food products in adequate manner (n=2525).

IQ-FRESHLABEL is a research project, partly funded by the European Commission in the 7th Framework programme. The project was running for three and a half years (1st August 2010 to 31st January 2014) with 17 partners from 9 different countries.

ttz Bremerhaven is an independent research institute and performs application-related research and development. Under the umbrella of ttz Bremerhaven, an international team of experts is working in the fields of food, environment and health. ttz has assisted enterprises of all sizes for over 25 years in the planning and implementation of innovation projects and the corresponding acquisition of funding at national and European level. http://www.ttz-bremerhaven.de

Im Focus: Production of an AIDS vaccine in algae

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.

The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...

Im Focus: The most accurate optical single-ion clock worldwide

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Im Focus: Flow phenomena on solid surfaces: Physicists highlight key role played by boundary layer velocity

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.

The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
