Intelligent packaging(Def. EU 1935/2004 and EU 450/2009)

• Intelligent materials and articles:– They monitor the condition of the packaged food or the

environment surrounding the food– No changes in characteristics of food productse.g. Time-Temperature Indicators (TTI)

≠ active packaging:– Intended to extend the shelf-life of packaged food

Or– To maintain or improve the condition of packaged foode.g. Oxygen absorbers© 2012 – Pack4Food


Types of intelligent packaging

In general: two types

1. Measuring the condition of the package onthe outside

2. Measuring directly the quality of the foodproduct inside the packaging



Extension of functionality of food packaging

• Containment

– Related with mechanical properties

• Protection

– Against external factors

• Convenience

– “easy-to-use”

• Marketing

– Providing information

Leak detection systems

Added value by intelligent materials

Quality indicators

• Colour change depending on changes in quality of the food product– Flavour components, ethylene,…

– Microbiological metabolites,…

• Not much commercial applications

• Lots of research/patents

• Focus on:– Following up ripening processes (e.g. fruits)

– Following up amine-production (e.g. fish)



Quality indicators

• Ripesense ®



Quality indicators

• SensorQ™ (Food Quality Sensor International / DSM)– pH-sensing technology (based on anthocyanines)

– Detects freshness/spoilage level of packed meat and poultry by reacting with biogenic amines from microbiological origin

– Label

– Orange-colored center in ‘Q’ turns dark

green if meat is spoiled

• O2-indicators

– Ageless Eye®




• Actually measuring the O2-concentration: exampleOxysense

Project proposal

Optical sensors for integration in food packaging• Extremely cheap optical sensor

• With multiplexed sensing capabilities (specificity!!)

• To be read out contactless by laser/LED beam

Project proposal

Adsorption gas sensor



Project proposal: why silicon photonics optical sensor?

• Cheap (CMOS-technology): order eurocent

• Extremely small: mm2

• Non-contact: read-out through package foil

• Signal of sensor not visible for consumer

• Sensitive and (!) specific

– Sensitive: optical resonant phenomena

– Specific: dense integration of dozens of resonators



Project proposal

• Project proposal to be submitted to IWT in the framework of SBO– “Strategisch Basis Onderzoek”

– Deadline: 7th of January 2013

• Participation companies to users group– Follow up developments project in first line

– Possibility to steer the project

• Based on obtained results, valorisationprojects will be submitted© 2012 – Pack4Food
