Optimisation and scale-up of cellulose fiber based packaging, focused on solid board with the integration of printed intelligence . (Mindaugas Bulota, Bumaga)

This ER will work across WP3 and WP4. In WP3 the research will be directed to market applications of innovative paper and board products. Using a solid board package with printed intelligence as the target product the ER will become proficient in product development and production, project management, project support market exploration and market introductions. In WP4 the ER will minimise losses in production and minimise the wastage in the product package.

Modifying the surface of cellulose to impart active properties. (Seema Saini, INPG PAGORA)

The grafting of polysaccharide nanoparticles, or indeed, cellulose nanoparticles has received little attention Consequently, the ESR will develop efficient strategies for the chemical modification of cellulose whiskers, or MFC, in order to deliver functional, and economically sustainable, grafting processes that will anchor active molecules, or oligomers, to the cellulose surface. The grafting of cellullose will be achieved by: i) evaluation of candidate grafting molecules or oligomers on cellulose fibres or nanocrystals from both traditional sources and waste (beet pulp or sugar cane bagasse), ii) optimising a solvent free/green reagent route, iii) producing useful quantities of surface-modified cellulose, and analysing the active properties, v) producing the end–use packaging material: composite, fibre based material.

Developing active packaging solutions through incorporation of organic/inorganic active components in renewable materials  (Joana Mendes, SSCCP)

This ESR will work across WP3 and WP4. In WP3 the ESR will be trained in the use of several methods of incorporating active functionalities (antimicrobial, antioxidant, anti-ripening, barrier) in renewable packaging materials. The major focus will be on bio-chemical approaches (enzymatic and chemical grafting) and physical modification. Then, as part of WP4, the most promising candidate materials will then be evaluated with respect to Packaging End-of-Life options. The major focus will be on recyclability taking into account both material recyclability and organic recovery. The latter will be studied in both aerobic (compostability) and anaerobic (biogas production) environments. Finally, the impact of different modification routes on Life Cycle Analysis and carbon footprint of selected materials will be assessed.

Active coatings based on multiphase dispersions  (Qihao Tan, ZUT)

This ESR will develop new ‘smart delivery systems’ in which stable emulsion systems, including micro- and nano- capsules, will change their release profile as a function of external parameters including water adsorption, humidity, temperature or pH. For example, pH-dependent antimicrobial release will be achieved using polyelectrolyte complexes of antimicrobial proteins, such as enzymes and bacteriocins with, for example, appropriate combinations of anionic and cationic polysaccharides. The controlled release of other actives e.g. aroma profilers or indicators will also be evaluated. Smart, reactive coatings will be achieved by developing enzyme mediated cross-linking between biopolymeric micro- and nano-carriers and active substances such as enzymes and bacteriocins, thus, simultaneously achieving a higher stability without changing the active properties.

Active packaging materials with the ability to release active substances via physical or chemical triggering and modulating mechanisms. (Sofiya Shopova, ITENE)

The ESR will identify and develop new systems with the ability to incorporate and release active moieties (antimicrobials and antioxidants) after being triggered by changes in physical properties such as temperature, humidity, pH, or via enzymatic action. The ESR will evaluate combinations of biopolymers, encapsulating agents, precursors, antimicrobial and antioxidant agents. The resulting candidate delivery systems will be incorporated into trial packages and the effect of external factors on the release kinetics of the active substances will be systematically evaluated in vitro. In the final phase the optimum active packaging will be tested against the food products and the impact on the microbiota will be analysed taking into consideration the contribution of the head space as a food-package contact mechanism.
