Parma Ham Consortium identifies alternative materials for pre-sliced packs
In a bid to reduce the environmental impact of its members’ production activities, Prosciutto di Parma has carried out research to identify more sustainable alternatives to the traditional packaging of pre-sliced products.
Driven by consumption habits that have strengthened considerably during the pandemic period, sales of Parma Ham packs performed exceptionally well in recent years, according to the consortium. Despite the fact that consumers’ purchasing choices have privileged the deli-counter after the limitations imposed by Covid-19, in 2022 more than 90 million packs were sold in Italy and in foreign countries including the UK, a figure well above that of 2019.
Alessandro Utini, president of the Consortium noted the great success of Parma Ham, which has always played a fundamental role for the social and economic resilience of the province of Parma, but insisted the aim now is to strengthen the environmental sustainability and circular economy of Parma Ham.
The Consortium carried out in-depth research in collaboration with the Experimental Station for the Parma Food Conservation Industry (SSICA), to test alternative and more sustainable materials than those traditionally used for packaging pre-sliced ham. Shelf-life tests were carried out with packaging from several sources and with different recycling methods, such as paper, recyclable PET and compostable bioplastics.
The use of these materials stems from the desire to guarantee a supply of raw materials of renewable origin that are sustainable for the planet, and from the need to foster every possible form of reuse or recovery of waste after consumption. The selected materials were combined in different types of packaging and used for packaging trials in a protective atmosphere with Parma Hams from different producers and maturation periods, ranging from 16 to 20 months.
“At the end of the monitoring period, the packs underwent chemical-physical, sensory and microbiological analyses with extremely significant results. We highlight the fact that packs consisting of paper tray and paper top (with or without transparent window), yielded even better preservation performance than traditional materials, also in terms of durability. Paper is therefore an excellent solution for the packaging of our pre-packed products, thanks to its recyclability, ease of reuse and origin from a renewable source,” comments Alessandro Utini.
Tests on other materials showed the PET tray, with a shorter shelf-life than paper, is suitable for sale in transparent packaging, while the compostable bioplastic-based packages guarantee a shorter shelf-life, compatible with a ‘take away’ sales formula.
“The research, completed by our Consortium, has successfully identified valid alternatives to traditional packaging and has provided manufacturing and packaging companies with important tools to support their already substantial commitment to sustainability. The transition to alternative and more sustainable materials, even in a macro-economic and production context that will require commitment and time to be fully implemented, and is therefore not only desirable but finally possible,” President Utini concludes.
