Experts are increasingly relying on optical technologies to drive a meaningful reduction in food waste while enabling real-time monitoring of food conditions. This approach supports better decision-making across the supply chain, with a strong focus on human health, safety, and commercial value.

What is Smart Photonic Packaging?

Three Major Types of Packaging Technology

There are three major types of packaging technologies employed globally to ensure food safety and preservation. Active food packaging extends the shelf-life of food products by releasing substances like antioxidants and anti-microbials from the packaging to interact with the food and the environment.²

Intelligent food packaging continuously monitors the food products and the surrounding environmental parameters, ensuring food quality, minimizing food spoilage, and ensuring human safety.³

The most advanced type of packaging is the photonics-enabled or smart photonics packaging for the food industry. It involves the integration of optical sensing mechanisms and photonic components into packaging devices, enabling real-time food monitoring, chemical changes analysis, and multisensory smart monitoring of chemical changes and ecological parameters.

Integration of Optical and Photonic Components into the Packaging Material

The photonic packaging involves the integration of optical sensors within the packaging devices, allowing for high-speed signal and data transmission from the sensing platform, with low latency and high energy efficiency.⁴

The integration of smart optical sensing intelligent components, like sensors using quantum dots (QDs), and fluorophores can be done by directly embedding them into packaging films using printing or mixing them into the polymeric film during fabrication. These optical sensors allow for monitoring of oxygen levels, moisture levels, gas levels, and various contaminants.⁵

The detection mechanisms of these optical sensors integrated within modern photonic food packaging include fluorescence dye quenching, colorimetric detectors, and the utilization of Surface-enhanced Raman spectroscopy (SERS) substrates.

Optical Sensing Technologies Enabling Food Safety Monitoring

Fluorescence-Based Spoilage Detection

The degradation of food leads to changes in pH levels due to microbial activity and protein degradation. The pH-responsive fluorescence-based packaging systems have become critical in recent years to ensure food freshness and safety. Fluorescent materials with excellent biocompatibility and lower toxicity are the most promising materials for pH-responsive sensing packaging platforms.

At present, most systems rely on either visible color-change detection or fluorescence-based sensing. More recently, researchers have developed dual-mode sensing packaging films that combine fluorescein isothiocyanate (FITC) with anthocyanins extracted from dragon fruit peel. These films leverage both FITC fluorescence and the visible color-change properties of the anthocyanins, creating a complementary sensing approach.

The result is a packaging solution that has proven effective for both meat and fruit-based products, enabling non-destructive, real-time monitoring of food quality.⁷

The real-time monitoring of biogenic amines like histamines by fluorescent sensors makes them a good choice for integration with food packaging. Research studies have demonstrated their efficiency as sensor-based hydrogels, smart photo-responsive labels for industrial use, and logic devices enabling real-time monitoring of biogenic amines, for the indication of food spoilage.⁸

Raman and SERS-Based Packaging Sensors

Raman spectroscopy is becoming crucial for applications in food quality monitoring and safety analysis. Food components inherently have weak Raman scatterer constituents, rarely interfering with Raman signals. Furthermore, deep penetration of food samples during Raman spectroscopy allows for inelastic scattering, revealing critical information about food molecules.⁹

In particular, Surface-Enhanced Raman Scattering (SERS)-based sensors have proven highly effective for detecting food contaminants. These simultaneous detection strategies are generally classified into two approaches: label-free and labeled methods.

SERS-based sensing relies on substrates composed of noble metal nanoparticles, which amplify the Raman signal of target food analytes. This signal enhancement enables the detection of contaminants at extremely low, trace-level concentrations, making SERS a powerful tool for food safety monitoring.¹⁰

While SERS-based packaging sensors are quite reliable, the cost of developing reliable substrates is quite high. Experts are working hard to develop reusable and low-cost substrates with analyte enrichment features to facilitate food quality analysis in complex environments.¹¹

Time–Temperature Indicators (TTIs) Using Optical Readouts

Precise temperature regulation is critical for preserving food quality and ensuring adherence to quality standards. Time–Temperature Indicators (TTIs) are a critical technology for contact-based thermal sensing, easily attached to modern food packaging, monitoring real-time changes. They are critical for comprehensive temperature traceability, ensuring cold chain integrity, allowing for uninterrupted, thermally-regulated supply-chain process optimized for storage and transportation of food products.¹²

The temperature fluctuations in perishable food products lead to irreversible changes in color. The integration of photonic TTIs allows for the provision of visual information, allowing consumers to judge the quality of food.¹³

Industry Drivers Behind Smart Photonic Packaging Adoption

The demand for smart photonic packaging in the food industry has increased significantly due to different factors. Firstly, the food safety regulations and standards are becoming stricter to ensure a decline in food-related diseases. The U.S. Food and Drug Administration has implemented the FDA Food Safety Modernization Act (FSMA), which is a transformative safety system focusing on preventing foodborne illness, rather than reacting to it.¹⁴

There has also been a sharp rise in demand for preservative-free, fresh food products, making an intelligent packaging system essential for monitoring environmental parameters. Furthermore, cold logistics and supply chain systems are also being optimized for reducing the amount of food waste generated before reaching the consumers. In this regard, photonic packaging is crucial for ensuring the safe storage and transportation of perishable goods.

The European Union is funding a project titled FoodPackLab 2, in which companies and organizations from 5 different countries are focusing on the development of smart, photonic packaging for food items.¹⁵ Photonic Biosystems has also been developing optical intelligent sensing systems for food packaging, with their intelligent non-invasive optical sensing platforms for food packaging enabling real-time measurements.¹⁶ These examples highlight the commercial importance of photonic smart packaging systems for achieving Sustainable Development Goals (SDGs), by ensuring less food spoilage.

Manufacturing and Integration Challenges

While photonic smart packaging is a game-changer for the food industry, the manufacturing, printing, and integration costs for photonic components and nano-sensors are limiting their widespread usage in industrial settings.¹⁷ Studies have also revealed that optical components and photonic packaging materials degrade with varying temperatures and time. These factors significantly affect the shelf life of the photonic packaging, with companies working to improve the shelf life of sensors.

To tackle these challenges, the focus has been shifted towards other technologies, such as printable smart photonic packaging with longer shelf life and lower manufacturing costs.¹⁸ Another crucial technology is the Roll-to-Roll (R2R) processing, allowing for industrial-scale fabrication of large-area photonic devices on flexible substrates, making them perfect for food packaging and safety monitoring.¹⁹

How Smart Photonic Packaging Reduces Food Waste?

The components within the photonic smart packaging allow for optical analysis of food products to predict a dynamic expiration date based on real-time quality of food items and environmental parameters. If the condition of fruit or meat-based products is deteriorating rapidly, photonic smart packaging sends alerts to the consumer, even if the printed expiration date is much further away.

Future Developments

Many developments are being made in the field of photonic smart packaging, where Optical Phased Array (OPA) components are being integrated within photonic smart packaging. These optical systems have much lower power consumption while providing high-speed monitoring capabilities for food products.²⁰ Multi-phase and multi-modal photonic sensing platforms are being tested and integrated with traditional packaging systems to enable high-quality smart monitoring systems optimized for food products. Modern manufacturing techniques like nanoimprint lithography (NIL) allow for the manufacturing of complex optical structures for photonic smart packaging, allowing for cheaper large-scale fabrication of smart food packaging.

The implementation of smart photonic packaging in the food industry is proving to be revolutionary, paving the way for next-gen food monitoring systems. The integration of digital systems like AI models and Convolutional Neural Networks (CNNs) has improved monitoring capabilities while reducing power consumption. The future holds great promise for smart photonic packaging, with large-scale industrial implementation looking possible in the next 15-20 years.
