– NFCs
8. TTIs are a refined proven technology
Remain relevant since temperature governs reaction rates
and controls microbial growth
Convey end of shelf life-TTIs

Convey end of shelf life-TTIs
• L5-8 Smart Seafood
• irreversible color
change from the
hydrolysis of
triglycerides
• CoolVu
• aluminum
layer thins
causing a
reaction
• FreshCode, Varcode
andTempix, Tempix
• fading barcodes
• FreshMeter
• turns from blue to
gray via
benzopyridine
photoactivation
10. Beyond a “sniff” test
Degradation sensors – advanced materials research needed to link
deteriorative reactions to action
Convey end of shelf life-Degradation sensors
11. Seamless integration into packaging
Graphene printing and conductive polymers
Convey end of shelf life-Degradation sensors
12. Seamless integration into packaging
TVB-N, VOC or H2S indicators (VTT Finland)
UV activated CWI (Chulalongkorn; CIFP; FoodFresh)
When CO2 drops below defined value (NOVAS)
pH sensors
Florescence sensors; Sentinel Wraps; Toxinguard
Convey end of shelf life-Degradation sensors

13. Increase shelf responsive packaging
Microbial activity is sensed and then reduced
Gonzalez-Solino, Di Lorenzo (2018) Rana, Kumar and Ramalingam (2015)
14. Increase shelf responsive packaging
Microbial activity is sensed and then reduced
Gupta et al. 2002
Zhang et al. 2017
15. Key TakeawaysIncrease shelf responsive packaging
Oxidative activity is sensed and then reduced
Cruz et al. 2012
16. Key TakeawaysIncrease shelf responsive packaging
Oxidative activity is sensed and then reduced
Wang et al 2015
17. Key TakeawaysIncrease shelf responsive packaging
Oxidative activity is sensed and then reduced
Thanyacharoen et al. 2017
Basuki et. al. 2016
18. Design for secondary markets
Food shelf and diversion to allow short shelf life foods to be used within limited
time frame
Mechanisms to gather, track, trace and provide rigid COC
Mechanisms to increase shelf life on short shelf life products
Additive shelf life packaging to add shelf life
22. Link to Consumer use:
Home services (oven, refrigerators, pantry)
Recipe systems (allrecipes.com)
Grocery orders
Fitness apps
IoT & IoP
23. Intelligent and responsive packaging can improve sustainability, decrease food waste and
enhance the consumer experience
Design for recycle, separation and accompanying identity technology will improve collection
and sorting of post-consumer packaging
Food waste reduction involves wider value chain to meet consumer and manufacturer needs
CWI technology is moving ahead of traditional TTIs and freshness indicators
Oxidation can be reduced via light responsive packaging, reversible polymers, and
application of hydrogels
Microbial activity can be reduced via bioresponsive hydrogels, pH responsive
polysaccharides and biofilms
Enchanced consumer experience can align with IoT to provide a rich brand experience
