What is that?
In brief, active packaging is, of course, packaging which, on top of the traditional passive barrier and information functions, is specifically designed to change the condition of the packed food to extend shelf-life, improve safety or enhance sensory properties.
How about the Artibal's concept?
In ARTIBAL´s concept, the active material is included in the packaging as a coating in the inner part of the material, instead of being introduced in the structure of the polymer. It is based on the inclusion of the structure of the coating of the active natural components.
What's the good thing about that?
Since the coating is used only as a very thin layer, the amount of the material used is very small compared to other options. Also, it is active both in direct contact (as traditional materials) and in vapour-phase migration, thus reducing the risk of product alteration as well as chances for undesirable migration.
These examples provide general information of the antioxidant (AOX) protection provided by our active coatings.
It is interesting to highlight that the AOX effects are in some cases additives to the antimicrobial ones, therefore a single product can provide complete protection for a given foodstuff.
Following set of pictures illustrate the preservative effect obtained with one of our active coatings in combination with modifed atmosphere for lamb meat stored for 11 days at 1 ºC.
As can be seen, there is a clear effect on red colour and packaging also prevents the black-bone effect. Control is a usual modified atmosphere packaging. Graph below gives the CIE a* value as a function of storage days.
Blue line represents control, whereas green circle, red line and green triangle represent ATOX 101 AV, 102 AV and 104 AV active solution, respectively.
Not only red colour preservation, but also prevention of lipid oxidation is another key feature of our active packaging. Here is a graph illustrating this effect, with the same colour code as before.
Following set of pictures illustrate the preservative effect obtained with one of our active coatings in combination with modifed atmosphere for beef meat stored for 20 days at 1 ºC.
As illustrated, red colour preservation is also obtained. Graph below shows the CIE a* value as function of storage time.
Blue line represents control, whereas orange triangle, orange square, orange circle, and red line, represent ATOX AV 1005, 101, 102, and 104 active solutions, respectively. Ligth blue straight line represents minimum acceptable a* value.
Again, prevention of lipid oxidation is another key feature of our active packaging. To the right, there is a graph illustrating this effect, with the same colour code as before.
Not only meat, but also a wide range of different products including but not limited to fish, fruits, snacks, and so on, are nowadays being protected using our products.
If you want to find out how to use our system in your own situation, please do not hesitate to ask
Following examples illustrate the usefulness of different ARTIBAL´s active packaging solution against diferent microorganisms prevalent in food-related diseases.
All pictures in this page have been obtained in tests performed against microorganisms inoculated in their specific culture media under their optimum conditions. Also, it has to be highlighted that initial population is about 100,000 CFU per mL.
This conditions are, obviously, much more critical than these found in real-life situations. Finally, only plastic material is depicted, but our active coatings can be successfully applied to other materials such as paper and board, aluminum and more…
First picture set demonstrates inhibition against a variety of fungi: (A) Penicillium nalgiovense, (B) Eurotium repens, (C) Zygosaccharomyces rouxii and (D) Debaryomyces hansenii.
Next picture set demonstrates inhibition against a variety of Gram positive bacteria: (A) Staphylococcus aureus, (B) Bacillus cereus, (C) Enterococcus faecalis and (D) Listeria monocytogenes.
Final picture set demonstrates inhibition against a variety of Gram negative bacteria: (A) and (B) Yersinia enterocolitica, (C) Escherichia coli and (D) Salmonella choleraesuis.
Due to Secrecy/Confidentiality Agreements with our Clients, we are not allowed to disseminate information for all products under this section. Therefore, only a couple of examples are shown in order to illustrate effectiveness and applicability of ARTIBAL´s active coating to different materials and foodstuffs.
Antimicrobial PET & peaches
To the left, inactive PET packaging. As can be seen, “healthy” proliferation of Rhizopus stolonifer (aka. nigricans) was found. To the right, active PET packaging, including an inner coating of an ARTIBAL´s active product. Peaches were collected and stored identically as these on top of this paragraph.
Images speak by themselves.
Antimicrobial paper & dessert
On top of this letters, another example of an ARTIBAL commercial active product. Protective coating was applied to the paper in contact with the product (product to the left), and completely prevent fungi proliferation (please compare to control to the right), without organoleptic alteration. Shelf-life was increased a grand total of 50%.
