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.

R2D2, a joint project to analyze and development high-TRL processes and technologies for manufacture of flexible organic light-emitting diodes (OLEDs) funded by the German Federal Ministry of Education and Research (BMBF) has been successfully completed.
In contrast to point light sources like LEDs made of inorganic semiconductor crystals, organic light-emitting diodes (OLEDs) are light-emitting surfaces. Their...

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."
Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is...
Physicists in Innsbruck have realized the first quantum simulation of lattice gauge theories, building a bridge between high-energy theory and atomic physics. In the journal Nature, Rainer Blatt‘s and Peter Zoller’s research teams describe how they simulated the creation of elementary particle pairs out of the vacuum by using a quantum computer.
Elementary particles are the fundamental buildings blocks of matter, and their properties are described by the Standard Model of particle physics. The...
