How does it work?
|Primary objective||to monitor the growth of microorganisms in packaged food product|
|Working principle|| Chemical, physical principle: Intelligent packaging systems in food processing include the application of different indicators which are able to monitor the state and quality of the product. The indicators monitoring the microorganisms growth in packaged products can facilitate the visual differentiation of quality and spoiled products.
Working principle of microorganism growth indirect indicators consists of visible monitoring of gas and/or volatile substances produced in the package (CO2, H2S, volatile amines, ammonia, hydrogen sulfide, diacetyl, etc.), change of pH value of the packaged foodstuff, etc.[3,6,11,16].
Biological principle: Packaging indicators with visual response based on immunochemical reactions (antibody reaction based indicators), (antibody is gained from blood of immunised experimental animal (e.g. rabbit)) were already developed for the monitoring of the growth of particular type of microorganisms, e.g. Escherichia coli, Pseudomonas. Some indicators are based on detection of specific metabolites (microbial enzymes, toxins, etc.). Application of biosensors in this context could be expected in the future [2, 10, 21].
Further details of the topic can be received by the studying the literature, see e.g. [1,4,5,7,8,9,12,13,14,15,17,18,19,20,22,23].
|Additional effects||Instant information about the microbiological quality of packaged product, consumer convenience.|
|Important process parameters||Design of the indicator, package suitability for indicator application, treshold level of indicator, qualitative or quantitative output, range of validity.|
|Important product parameters||Composition of the product should be related to indicator selected.|
What can it be used for?
|Products||All perishable food products, e.g. minimally processed food, ready to eat products that are stored chilled|
|Operations||Packaging, storage of packaged products.|
|Solutions for short comings||Food shelf-life extension, food safety|
What can it NOT be used for?
|Other limitations||Hygienic restriction, acceptable price|
|Risks or hazards||Food contamination|
|Maturity|| Production of packaging indicators based on chemical reactions with microorganism metabolites is the mature process. Other packaging indicators monitoring microorganism growth in packaged food are in the stage ranging from theoretical speculation to laboratory testing.
At the commercial level: - Application of CO2 indicators, e.g. Reflex (Cryovac Sealed Air), volatile amine indicators, e.g. FreshTag (Cox Recorders), hydrogen sulfide (VTT) - Application of immunochemical indicators for detection of Escherichia coli growth (Food Seantinel System) or Pseudomonas contamination (Toxin Guard).
At the research level: - Immunochemical indicators for wider scale of pathogenic microorganisms.
Indicators on the base of biosensors and/or nano-sensors.
|Modularity /Implementation||Production of the indicators of microorganisms’ growth suitable for application on food package can be inserted in existing production lines.|
|Consumer aspects||It can be expected that consumers will accept food packaging systems with the indicators of microorganisms’ growth.|
|Legal aspects||There is a general hygienic legislation on practical application of active and intelligent packaging systems for food processing in EU (Regulation No. 1935/2004 and 450/2009)|
|Environmental aspects||There is little information concerning environmental impact of wide scale indicator production.|
