“…The systems produced from natural polymers are associated with poor properties and, often, they have inferior characteristics compared to commodity polymers. As opposed to most synthetic plastics used as packaging materials, most of the currently available bioplastics do not fulfil the key requirements of food packaging, especially in terms of barrier and mechanical properties . Performing a modification technique is one way of improving properties and achieving the property combinations required for specific applications.…”

[76][77][78] Performing a modification technique is one way of improving properties and achieving the property combinations required for specific applications. The chemical structure of biopolymers can certainly open up possibilities for their reactive modification, and the modification strategies of the starting material should be those that enhance water resistance, the barrier effect and mechanical properties, allowing the incorporation of active ingredients to promote adhesion to the surface of food and to increase the stability to storage conditions.…”

Sustainable control strategies for plant protection and food packaging sectors by natural substances and novel nanotechnological approaches

An overview is provided of the current technological strategies (also at the nanoscale level) recently involved in plant and/or food protection. In addition, the potential use of natural and sustainable substances, instead of traditional synthesized molecules or chemical-based compounds, is addressed both with respect to packaging systems and novel pesticide formulations. In this context, nanotechnological approaches represent promising strategies for the entire agriculture industry chain, from the field to consumers. Traditional plant protection strategies are often insufficient and the application of chemical-based pesticides has negative effects on animals, humans and the environment. Novel greener tools could represent efficient alternatives for the management of plant diseases using promising strategies; the use of nanotechnologies allows the promotion of the more efficient assembly and subsequent release of environmentally sustainable active principles, limiting the use of chemicals in terms of economic losses. At the same time, new sustainable, antimicrobial and antioxidant systems have been rapidly promoted and investigated in the food packaging sector as a valid eco-friendly possibility for improving the safety and quality of food products and reducing and/or limiting the environmental impact with respect to traditional materials. Together, the scientific community and the growing interest of consumers have promoted the development of new edible and eco-friendly packaging that reduces waste and any environmental impact. In this context, the aim is to provide evidence of the usefulness of strategies aiming to limit agrochemicals, as well as the potential of nanomaterials, in sustainable plant and food protection for agriculture management and the packaging sector. © 2018 Society of Chemical Industry.

“…Four industrial untreated kraft papers of same chemical composition but different basis weight and pulp refining degree have been chosen as fibrous supports for coating due to their widely available character, and common use for food packaging applications (e.g., sachet for bread or fresh fruits and vegetables). Wheat gluten (WG) have been considered for coating because of its very interesting gas transfer properties: relative humidity dependent gas transfer and surface properties and high permselectivity ratio (CO 2 permeation / O 2 permeation) at high relative humidity, especially for fruits and vegetable packaging . Four WG‐coated papers were produced in identical conditions from the four different supports and their final properties (surface and gas transfer) were discussed in relation with their structure and the in‐bulk structure of their respective coating support.…”

Composite materials made from fibrous support coated with agro-polymers are widely commercialized for different applications. But, their transfer properties have only been sparingly studied despite their importance in membrane technologies or food packaging. Furthermore, most of past studies on the topic have been focused on the impact of surface properties of the support on the final coated material structure and its properties; leaving unexplored the potential impact of the in-bulk structure of the support. This study demonstrated the influence of in-bulk structure and especially fibers refining degree of 4 kraft papers (SP28, 36, 60, and 80) on the structure, and surface and gas transfer properties of their respective wheat gluten (WG) coated papers (WGP28, 36, 60, and 80). Paper presenting a high fibers refining degree (SP28) exhibited very tight and narrow in bulk fibers network which prevented most of the WG-coated layer penetration, maintaining an important WG apparent layer on top of the paper and a small fibers/wheat gluten composite zone inside (WGP28). Such structure gave strong WG-like properties to the final coated material with moderate oxygen permeation and high permselectivity (1.50 x 10(-11) mol m(-2) s(-1) Pa-1 and 8.09, respectively for WGP28) whereas the highly impregnated structure of coated papers built on lowly refined papers (SP80, with wide and loose structure) gave coated materials presenting weak WG-like properties, supposedly due to a thick composite zone presenting interfacial defects, with higher oxygen permeation and very limited permselectivity (11.90 x 10(-11) mol m(-2) s(-1) Pa-1 and 1.06, respectively for WGP80)

“…Most of the MAP in the food industry is still based on a costly and time‐consuming trial and error approach. But recent developments of MAP modelling tools such as the Tailorpack (http://www.tailorpack.com) or the PackinMap (http://www.packinmap.com) online applications allow to design packaging materials specially adapted for MAP via reverse engineering . Respiratory parameters of the produce to be packed, its optimal atmosphere for preservation and the packaging dimensions are the input data for the model.…”

“…Conventional plastic packaging materials are known for their very low Pe O2 and limited S that would often lead to excessive anoxia and induce detrimental metabolic deviations. Macro/micro perforations are used to limit this drawback, but the permselectivity drops to a value of 1, unsuitable for generating the optimal modified atmosphere of most produce.…”

Nanostructuring and Microstructuring of Materials from a Single Agropolymer for Sustainable MAP Preservation of Fresh Food

et al. 2012

The main objective of the present work was to determine whether a single agropolymer [wheat gluten (WG)] could fit the modified atmosphere packaging (MAP) requirements of a range of six different fresh produce in key terms of oxygen permeation (PeO2) and CO2/O2 permselectivity (S) values. The required properties for optimal packaging of fresh fruits and vegetables were first evaluated using the Tailorpack MAP modelling software (UMR IATE, Montpellier, France) with packaging dimensions and respiratory and optimal atmosphere data as input parameters. Then, the modelled values obtained were compared with the properties of a range of WG composite films: monolayer self-supported or multilayer at microscale or nanoscale, cast or thermoplasticised, with different formulations (percentage of plasticisers or nanofillers). The experimental gas transfer properties that could be covered by these materials ranged from 0.05x1010 to 2.00x1010mol/m2sPa for PeO2 and up to 18.0 for S. These ranges are much larger than conventional plastics that exhibit PeO2 from 0.10x1010 to 0.20x1010mol/m2sPa and S up to 4.5. It was demonstrated from a food-requirements-driven (Tailorpack modelling) and a multiscale film structuring (WG-based composites) approaches, that transfer properties of WG-based films would fit the requirements of the six selected fruits and vegetables better than conventional plastics.
