INTRODUCTION
Recent era is known to improvet echno-commerciallys kills in every industrial sector. The
agro-food market is significantly increasing upward. With the dive rsification in agro-food
processingchain,packagingplaysacrucialroleinagricultureandalliedsciencesbyensuring
thesafetransportation,storage,andpreservationofvariousagriculturalproductstotheend
user. It involves the design, development, andimplementation of packaging materials and
techniquestoprotect,contain,andmarketagriculturalcommoditieseffectively.Theprimary
purpose of packaging in this field is to maintain the quality and integrity of agricultural
productsthroughoutthe supplychain, from farmto consumer. Itnotonly helpsto protect
crops,fruits,andvegetablesfromphysicaldamage,suchasbruising,crushing,orpuncturing
duringhandlingandtransportationbutalsoshieldingtheproducefromexternalfactorslike
moisture, pests, a nd disease. Packaging in agriculture serves a s a means of identification,
branding,andinformationdissemination.Labels,tags,andstickersprovideessentialdetails
aboutthe product,includingits origin,qualitystandards, nutritionalcontent,and handling
instructions. Nowadays well-designed and attractive packaging can enhance the visual
appealof fruits,vegetables, andotherproduce,makingthemmoreappealingtoconsumers
without changing its nutritional composition (Tiwari et al., 2021). Present scenario is
dealingwithsustainablepackagingpracticesthathavegainedprominenceinagricultureand
alliedsciences.Theindustryisactivelyexploringenvironmentallyfriendlymaterials,suchas
biodegradable films, compostable bags, and recyclable containers, to minimize the
environmental impact of packaging waste (Tyagi et al., 2021). The field of packaging has
witnessed a significant transformation with the advent of smart packaging technology.
Smart packaging integrates t raditional packaging materials with advanced technologies to

ClassificationofSmartpackaging
Thesmartpackagingsystemis classified intotwocategories asdepicted inFigure1.Active
packaging involves the incorporation of active compounds like antioxidants into the
conventional packaging materials to augment the stability and qualityof the foodproduct
throughouttheirshelflife(Dragoetal.,2020)whileintelligentpackagingisanintegrationof
traditionalpackagingwithmodernizedelectronicsensingdeviceslikesensorstodetectthe
change in the quality of thefood product to ensure thesafety of thefood before it reaches
theconsumers(Ahmedet al.,2022;Alamet al.,2021).Theactiveandintelligentpackaging
systems function as a protective barrier and shield the food material against various
physical, chemical, and biological hazards. They are also functional in indicating the
freshness and quality of the food product and continuously monitoring the time and
temperature of the food product which ensures the overall safety and quality of the
products.Boththeactiveandintelligentpackagingsystemsaimatimprovingfoodsafetyand
qualitybydeliveringsoundandnutritiousfoodtoconsumersbuttoachievethedesiredgoal
therolesplayedbytheactiveandintelligentpackagingsystemsaredifferent(Doderoetal.,
2021;Aminetal.,2022).
SmartPackagingTechnologies
1.ActivePackaging
Absorbers
Oxygen is a reactive gas that can lead to various undesirable changes in food, including
oxidation, spoilage, and degradation of nutritional value. The most commonlyu sed oxygen
scavengers are based on the principle of oxidation-reduction reactions. One widely used
type of oxygen scavenger is based on iron powder. These scavengers consist of iron
particles embedded in a polymer matrix. When exposed to oxygen, the iron particles
undergoachemicalreaction knownasoxidation,whichconvertstheminto ironoxide.This
reactionconsumestheoxygenpresentinthesystem,effectivelyreducingitsconcentration.
Asaresult,thefoodproductremainsprotectedfromoxidative deterioration. Anothertype
of oxygen scavenger is based ont hech emicalcompound so diumb isulfite.This scavenger
works by reacting with oxygen to form sodium sulfate and water. It is commonly used in
productssuchasbeverages,wherethepresenceofdissolved oxygencan lead tooff-flavors

andlossoffreshness.
MoistureAbsorbers
Moisture absorbers, also known as desiccants, are substances ormaterials that have the
ability to remove or reduce moisture content in their immediate environment. These
desiccants are typically employed in packagingor storage containers to prevent moisture-
related issues such asspoilage, mold growth, bacterial contamination, andloss ofproduct
quality (Alam et al., 2021). Silica gel is a porous, granular substance made from silicon
dioxide which has high adsorption capacity and hold moisture molecules from the
surroundinge nvironment. Silicagel is often placedi nsmall packets and insertedinto food
packagesorcontainerstoabsorbexcessmoistureandmaintainthedesiredhumiditylevels.
Calciumchlorideisahygroscopiccompoundthat hasastrongaffinityforwatermolecules.
It is frequently used in food packaging applications, particularly for products like fruits,
vegetables,and snacks.Furthermore,molecularsievesareemployedasmoistureabsorbers
in food processing. These sieves consist of synthetic zeolite materials with highly porous
structuresthatcan selectivelyadsorbmoisturewhileallowingothergasestopassthrough.
Molecular sieves are commonly used in the food industry to remove moisture from
powderedorgranularproducts,suchasspices,bakingmixes,anddryingredients.
EthyleneAbsorbers
Ethyleneisanaturalripeninghormoneemittedbyfruits,vegetables,andflowers,whichcan
acceleratethespoilageofnearbyproduce.Ethyleneabsorbershelpremovethisgasfromthe
packaging environment, extending the freshness and shelf life of the contents. Carbon,
zeolite, or potassium permanganate are the components which have high adsorption
capacities for ethylene. Ethylene absorbers actively remove ethylene gas from the
atmosphere when placed in storage areas or transportation containers. By reducing the
concentration of ethylene, the ripening process is slowed down, extending the shelf life of
freshproduce. This is particularlybeneficialinsituations wherefruits and vegetablesneed
to be transported over long distances or stored for extended periods. In large-scale food
processing facilities,e thyleneabsorbers are often integrated intoadvanced systems. These
systems may include ethylene monitoring and control mechanisms to maintain optimal
ethylenelevels.Bycontinuouslymonitoringtheconcentrationofethylene,theabsorberscan
beactivatedorreplacedasneededtoensuremaximumeffectiveness(Doderoetal.,2021).
AntimicrobialPackaging
Antimicrobial packaging in food processing is an innovative approach aimed at enh ancing
the safety and shelf life of food products by incorporating antimicrobial agents into the
packagingmaterials.Thistechnologyhasgainedsignificantattentioninrecentyearsdue to
theincreasing demandforfoodpreservationmethodsthatcaneffectivelycontrol microbial
growthandminimizetheriskof foodborneillnesses causedbySalmonella, Escherichia coli,
and Listeria monocytogenes. By incorporating antimicrobial agents, such as silver
nanoparticles,essentialoils,ororganicacids,intothepackagingmaterials,thepackaging
itself acts as a barrier against microbial proliferationa nd thusmaintai nthe freshness and
quality of the food f ora longer period. This is particularly beneficial for peris hable foods,
such as meat, seafood, and dairy products, which are highly susceptible to microbial
contamination.Antimicrobialpackagingalsooffersanadditionallayerofprotectionagainst
foodborne pathogens. Furthermore, antimicrobial packaging can reduce the need for
chemical preservatives in food processing which may have potential health risks and can
alterthetasteandqualityoffood(Alametal.,2021).
FlavorandAromaReleaser
Some packaging materials are designed to release flavors or aromas into the packaged
product,enhancingitssensoryappeal.Thisiscommonlyusedinthepackagingoffoodand
beverages.Flavorandaromareleasepackaginginfoodprocessingisaninnovativeapproach

aimed at enhancing the sensory experience and overall quality of packaged foodp roducts.
Thistypeofpackagingfocusesonpreservinganddeliveringthedesiredflavorsand aromas
of the food to the consumer, ensuring a more enjoyable eating experience (Tiwari et al.,
2021). There are several methods and technologies employed to achieve this goal. One
common approach is the use of barrier materials that help maintain the integrity of the
packaging, preventing the escape of volatile flavor and aroma compounds. These barrier
materialsmayincludelaminatedfilms,coatings, or encapsulationtechniquesthatcreate
a protective layer around the food product, effectively trapping the flavors and aromas
within.Additionally,activepackagingsystemsareemployedtoactivelycontrolthereleaseof
flavors and aromas (Janjarasskul and Suppakul, 2018). These systems often involve the
incorporation of additives or active ingredientsinto the packaging materials. For example,
controlled-release systems can be utilized, where microcapsules containing the desired
flavor compounds are embedded in the packaging. These microcapsules gradually release
the flavors and aromas over time, enhancing the sensory experience and prolonging the
shelflifeoftheproduct.
ActiveModifiedAtmospherePackaging(AMAP)
AMAPmodifyingthegaseouslevelssuchasoxygen,carbondioxide,andnitrogenwithinthe
package. Oxygen is usually reduced to inhibit the growth of aerobic bacteria, molds, and
yeasts, which are responsible for food spoilage (Janjarasskula nd Suppakul, 2018).C arbon
dioxide is increased to inhibit thegrowt h of spoilage microorganisms that are sensitive to
highcarbondioxidelevels.Nitrogenisaddedtodisplaceoxygenandmaintainthepackage's
structuralintegrity.Themodifiedatmosphereisachievedusingvarioustechniques, suchas
gasflushing,gaspermeablefilms,andoxygenscavengers(Lee,2021).Gasflushinginvolves
replacing the air inside the package with a predefined gas mixture. Gas permeable films
allowthecontrolledexchangeof gasesbetweenthe foodandtheenvironment,maintaining
the desired atmosphere. Oxygen scavengers are substances added to the package that
removeexcessoxygenandmaintainlowoxygenlevels.
2Intelligentpackaging
Time-TemperatureIndicators(TTIs)
Time-TemperatureIndicators(TTIs)areessential tools used infoodprocessingtomonitor
and ensure the safety and quality of perishable food products. They provide valuable
information about the cumulative effects of time and temperature on the food, allowing
producers,distributors,andconsumerstomakeinformeddecisionsregardingthefreshness
andedibilityoftheproduct.TTIsfunctionbyincorporatingachemicalorbiologicalindicator
thatreactstochangesintemperature over a specificperiod.Theseindicatorsare designed
tomimicthebehaviorofthefoodandprovideavisualindicationoftheproduct'squalityor
safety (Ahmed et al., 2022). They are typically placed on the packaging or directly on the
fooditemitself.TheprimarypurposeofTTIsistohelppreventfoodborneillnessescaused
bybacterialgrowthandtheformationoftoxins.Bacteriamultiplyrapidlyinthetemperature
dangerzone,whichisbetween40°F(4°C)and140°F(60°C).Bymonitoringthetemperature
history of a food product, TTIs can indicate whether it has been exposed to unfavorable
conditionsforanextendedperiod, potentiallyrenderingitunsafeforconsumption(Dodero
etal.,2021).TherearedifferenttypesofTTIsavailableforvariousapplications.SomeTTIs
employ time-temperature integrators that calculate the cumulative effect of temperature
exposureovertime. These indicatorschangecolorordisplay a visual signalwhenthefood
has been stored or transported at temperatures above a certain threshold for a
predeterminedduration.OtherTTIsutilizebiochemicalreactions,suchasenzymeactivityor
microbial growth, to indicate food quality. These indicators are particularly useful in
assessing the freshness of perishable items, such as meats, seafood, and dairy products.
Changesintheactivityorgrowthof specific enzymesormicroorganismscanbecorrelated


withthe product'sdeterioration,enabling consumersto make informeddecisionsaboutits
freshness.TTIsplayacrucialroleinthefoodsupplychain,allowingstakeholderstoidentify
potential temperature abuse during processing, storage, and transportation (Chen et al.,
2020). They help reduce food waste by ensuring that only safe and high-quality products
reach the consumer. Additionally, they provide a means for consumers to assess the
conditionofpackagedorpre-preparedfoods,promotingtransparencyandinformedchoices
(Poyatos-Racioneroetal.,2018;Alametal.,2021).
OxygenandMoistureSensors
Oxygen and moisture sensors play a crucial role in food processing, ensuring product
quality,safety,andshelflife.Oxygensensorsaredesignedtodetectandmeasurethelevelof
oxygenpresentinfoodpackagingenvironments,whilemoisturesensorsareusedtomonitor
andcontrolthemoisturecontentoffoodproducts.Bothsensorsareessentialinmaintaining
optimalconditionsduringprocessingandstorageto preventspoilage,extendshelflife,and
preserve the sensory and nutritional attributes of the food. Oxygen sensors are commonly
used in modified atmosphere packaging (MAP), which involves altering the atmospheric
compositioninsideafoodpackagetoslowdownthe deteriorationprocess.Oxygensensors
canalsobeusedinheadspaceanalysis,wherethegascompositionwithinasealedcontainer
ismeasuredtoassessproductquality(Aminetal.,2022).Moisturesensorsaremainlyused
in various food processing applications, such as drying, baking, and extrusion. Moisture
sensors measure the amount of water vapor present in the processing environment or
directly in the food. This information allows processors to adjust processing parameters,
suchastemperatureandhumidity,toachievethedesiredmoisturelevelsandpreventunder
or over-drying.P ropermoisture control helps maintain product texture, prevent microbial
growth,andensureproductsafetyandstability.
Radio-FrequencyIdentification(RFID)
RFID tags orlabels use radio waves to track and monitorthe movement offoo dproducts
throughout the supply chain.T heyprovide real-time data about the location, temperature,
and other conditions, enabling better inventory management and quality control. Radio-
FrequencyIdentification(RFID) tagsplayasignificantroleinfoodprocessing,providingan
efficientandreliablemeansoftrackingandmanagingvariousstagesofthefoodsupplychain
(Chenetal.,2020).Thesetagsaresmallelectronicdevicesthatuseradiowavestotransmit
data to a reader, enabling the identification and monitoring of products throughout their
journeyfromproductiontoconsumption.Infoodprocessing,RFIDtagsareusedinmultiple
ways to improve efficiency, traceability, and safety (Yu et al., 2022). RFID tags can store
importantinformationsuchasbatchnumbers,expirationdates,andmanufacturingdetails.
This enables streamlined inventory management, as the tags can be scanned quickly,
eliminating theneed formanual data entry and reducinghumanerror.Secondly,RFIDtags
are invaluable in tracking the movement of food items along the supply chain. From the
warehousetodistribution centresandretailstores,thesetags enablereal-timevisibility of
product location and quantity. RFID tags aid in traceability and recall management. In the
eventofafoodsafetyissueorproductrecall,theRFIDtagscanprovidedetailedinformation
about the affected products, allowing for targeted and efficient recalls. This capability
significantly reduces the time and cost associated with identifying and removing
contaminated or unsafe food from themarket, protecting both consumerhealth and brand
reputation.
Nanosensors
Nanotechnology-based sensors are used to detect and monitor specific compounds or
conditions in food. They can identify the presence ofpathogens, contaminants, or spoilage
markers, providing early warning signs and improving food safety. Intelligent packaging
utilizing nanosensors can provide consumers with interactive experiences. For example,

Food packaging encompasses the topical role of preserving food, hence, extending the shelf-life, while ensuring the highest quality and safety along the production chain as well as during storage. Intelligent food packaging further develops the functions of traditional packages by introducing the capability of continuously monitoring food quality during the whole chain to assess and reduce the insurgence of food-borne disease and food waste. To this purpose, several sensing systems based on different food quality indicators have been proposed in recent years, but commercial applications remain a challenge. This review provides a critical summary of responsive systems employed in the real-time monitoring of food quality and preservation state. First, food quality indicators are briefly presented, and subsequently, their exploitation to fabricate intelligent packaging based on responsive materials is discussed. Finally, current challenges and future trends are reviewed to highlight the importance of concentrating efforts on developing new functional solutions.

Food supply chain is a rapidly growing integrated sector and covers all the aspects from farm to fork, including manufacturing, packaging, distribution, storing, as well as further processing or cooking for consumption. Along this chain, smart packaging could impact the quality, safety, and sustainability of food. Packaging systems have evolved to be smarter with integration of emerging electronics and wireless communication and cloud data solutions. Although there are many factors causing the loss and waste issues for foods throughout the whole supply chain of food and there have been several articles showing the recent advances and breakthroughs in developing smart packaging systems, this review integrates these conceptual frameworks and technological applications and focuses on how innovative smart packaging solutions are beneficial to the overall quality and safety of food supply by enhancing product traceability and reducing the amount of food loss and waste. We start by introducing the concept of the management for the integrated food supply chain, which is critical in tactical and operational components that can enhance product traceability within the entire chain. Then we highlight the impact of smart packaging in reducing food loss and waste. We summarize the basic information of the common printing techniques for smart packaging system (sensor and indicator). Then, we discuss the potential challenges in the manufacturing and deployment of smart packaging systems, as well as their cost‐related drawbacks and further steps in food supply chain.

The dynamic interplay of food, environment, and human factors has expanded the role of active packaging in maintaining and improving food safety and quality, extending product shelf life, and promoting marketability. Given the desirability of active food packaging, continuous assessment of its safety and effectiveness is required. Recognizing the gap between research and commercialization, the latest innovations and technologies must comply with regulatory standards. This article provides an overview of the basic scientific work on active packaging, its existing industrial applications, future perspective, and market outlook. This review is based on related articles published from 2013 to present, focusing on three main modes of action: chemical absorption and scavenging, chemical release, and microbial control. Examples of commercial brands and European Food Safety Authority (EFSA)-endorsed active packaging systems were included to illustrate how the market potential of active packaging is hampered by current limitations in technology, consumer behavior, and legislation.

This review aims to provide an overview of the developments in biodegradable intelligent, active, and smart packaging for food application by highlighting their challenges and limitations. Essential oils and plant extracts has been successfully used in the development of intelligent and active biodegradable packages for foods. Polyphenols (especially anthocyanins) play a central role in the main application of intelligent and active packaging by indicating changes in food characteristics or improving shelf life, respectively. Smart biodegradable packaging is an emerging and promising area of research that has been receiving increasing attention in the last years as a major development from its two predecessors' strategies. Improvements are necessary to reduce the dependency on pH change in intelligent packaging, improve the controlled release of bioactive compounds in active packaging, and develop strategies to preserve film integrity in smart packaging.

Background: The technology of food packaging is responding to significant market dynamics such as the rapid growth in e-commerce and preservation of fresh food, a sector that accounts for over 40% of plastic waste. Further, mandates for sustainability and recent changes in national governmental policies and regulations that include banning single-use plastic products as observed in sweeping reforms in Europe, Asia, and several US States are forcing industries and consumers to find alternative solutions. Scope and approach: This review highlights an ongoing shift of barrier coatings from traditional synthetic polymers to sustainable breakthrough materials for paper-based packaging and films. Advantages, challenges and adapting feasibility of these materials are described, highlighting the implications of selecting different materials and processing options. A brief description on progress in methods of coating technologies is also included. Finally, the end fate of the barrier materials is classified depending on the packaging type, coating materials used and sorting facility availability. Key findings and conclusions" Different types of coatings, such as water-based biopolymers, due to their greater environmental compatibility, are making inroads into more traditional petroleum-based wax and plastic laminate paperboard products for fresh food bakery, frozen food, and take-out containers applications. In addition, nano-biocomposites have been studied at an accelerating pace for developing active and smart packaging. Based on the momentum of recent developments, a strong pace of continuing developments in the field can be expected.

Current food production faces a tremendous challenge due to the growing human population. The global population is estimated to reach 9 billion by 2050 with 70% more food being required. Safe food is an important dimension of food security, and food traceability across the supply chain is a key component of this. However, current food traceability systems are challenged by frequent occurrences of food safety incidents and food recalls that have damaged consumer confidence, caused huge economic loss, and put pressure on food safety agencies. This review focuses on smart food traceability that has the potential to significantly improve food safety in global food supply chains. The basic concepts and critical perspectives for various detection strategies for food safety are summarized, including portable detection devices, smart indicators and sensors integrated on food packages, and data-assisted whole-genome sequencing. In addition, new digital technologies, such as Internet-of-things (IoTs) and cloud computing, are discussed with the aim of providing readers with an overview of the exciting opportunities in smart food traceability systems.
