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.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
