Packing go bananas and questions about biodegradable alternatives

ZA Only Hanani, University Putra Malaysia (UPM), presented his work with NH Azmi for use of banana peel (drop) as biodegradable packaging films.

Knuth Lorenzen, President of Engineering and European Hygienic Design Group (EHEDG), gave an analysis of the potential savings in Cleaning in Place (CIP) plant foods through the hygienic design based on the work of Andreas Dorner, University of Munich art.

Horst-Christian Langowski, Technische Universität München, spoke of the challenges for food packaging in the coming decades.

Packaging bananas

Speakers and many spoke of his work on innovations in food packaging, shelf life and the Conference of Food Safety in Erding, Germany.

The event is jointly organized by Elsevier and the Fraunhofer Institute for Process Engineering and Packaging IVV organizes. Food packaging and durability is a magazine Elsevier.

ZA Only Hanani biodegradable films developed from peeled banana flour according to the casting process using glycerol, sorbitol and polyethylene glycol (PEG) as a plasticizer.

The products were homogeneous, opaque film with a dark brown green.

Movies banana peel with 40% PEG showed low permeability to water vapor (PVE) value and films with 10% PEG showed an increase in tensile strength (TS) and elastic modulus (EM) (P <0.05), followed by 10% and 20% glycerol ,

He concluded banana films exhibited a good sealability, so it can adapt to the pockets or bags of kibble and an alternative to plastics.

The initial cost discourages Hygienic Design

In his speech, Lorenzen said he chose the theme because the hygienic design is not in higher education to students who come from an engineering environment, have no idea, be informed.

With Dorner, hygienic design compared to tee designs watching valves and connections of sensors in order to provide guidelines for the food processor if you are looking for components to enable effective and easy cleaning.

Lorenzen said no hygienic design is up to 20% of the GMP and the cleaning process can take up to 70% of total water consumption and water treatment consume responsible.

"Hygienic Design offers savings in operational costs and reduced cleaning time, which means more production time, reduce chemicals, additives, electricity, steam, fuel and water treatment costs and water.

"Hygienic Design improved cleaning and sterilization by improving the flow of mass and heat transfer of CIP fluids."

End of life packaged foods

Langowski says what appears to be an opportunity for biopolymers are based on the current end of life issues with plastics, may in fact be a step backwards for the effectiveness of the package as a whole in accordance with the legislation possible.

Pollution from waste plastics is an area of ​​high concentration and biodegradable materials are used as a solution to the problem, he said.

The measure encouraging policies influenced mainly plastic bags so far, but Langowski said it could be a model for other plastic containers with taxes / fees or through compulsory purchase, partial or complete bans and the negative image it to be located towards the public.

Unlike biological function in many plastics and basic plastics is great present, "he said, adding that it will be set up for economic mass production of highly functional materials bioplastics packaging to take" for decades. "

Langowski asked the food packaging industry and efforts to the end of life, such as the recycling and recovery of packaging waste and warned if unsuccessful, the consumer pressure could have the right to enforce.
