“…What is more, some firms have incorporated initiatives such as assigning a carbon rating to their products [48]. Moreover, the energy waste in the production of materials is an environmental concern that requires us to establish appropriate actions [63]. In addition, packaging processes must be safe not only for the environment but also for human health [2], making it important to research, for example, the use of antimicrobial packaging strategies [64], especially for food and cosmetics [65].…”

Green Packaging from Consumer and Business Perspectives

Sustainable development is a global objective that aims to address the societal challenge of climate action, the environment, resource efficiency, and raw materials. In this sense, an important strategy is the promotion of green packaging, that is, the use of sustainable materials and designs for the packaging of goods. In recent years, many research works have been published in the specialised area covering the different perspectives and dimensions of green packaging. However, to our knowledge, no previous investigations have analysed the research activity on green packaging from business and consumer perspectives. The present study intends to fill this gap by analysing all of the publications found in the Scopus database with the help of visual analytic tools, including word clouds and Gephi network visualization software. More specifically, our study analyses the impact of green packaging from business and consumer viewpoints, including some specific issues such as the design and materials used in green packaging, green packaging costs, marketing strategies and corporate social responsibility related to green packaging, and the impact of green packaging in waste management, the circular economy, logistics, and supply chain management. The results obtained reveal the growing interest of scholars and researchers in all of these dimensions, as is made patently clear by the increasing number of journal publications in recent years. The practical implications of this study are significant, given the growing awareness among companies and consumers about the importance of the promotion of sustainable development through green packaging alternatives. More specifically, the results of this research could be very useful for all of those agents who are interested in learning about the main lines of research being developed in the field of green packaging.

“…Researchers specialising in important industries are investigating how to develop sustainable initiatives, not only to overcome the challenges of reducing gas emissions, but also in terms of energy costs [52,63]. With respect to green packaging, manufacturers choose packaging based on costs and consumer preferences [69].…”

“…Moisture content was determined by recording the sample mass at similar time intervals, and moisture content was calculated as shown in Equation (2).

where Mcws is the container plus wet sample mass (mg), Mcs is the mass of the container plus dried sample (mg), and Mc is the container mass (mg) [ 26 ].…”

Impact of Drying Regimes and Different Coating Layers on Carboxymethyl Cellulose Cross-Linked with Citric Acid on Cotton Thread Fibers for Wound Dressing Modification

et al. 2022

The oldest preservation techniques used are drying techniques, which are employed to remove moisture and prevent microorganisms’ growths, prolonging a material’s shelf life. This study evaluates the effects of drying methods on carboxymethyl cellulose (CMC) + citric acid (CA) coating layers on cotton threads. For this reason, cotton threads were washed and then coated with different layers of CMC cross-linked with CA, followed by drying using an oven (OD), infrared (IR), and a combination of oven + IR (OIR) drying methods at 65 °C. Our investigations revealed that CMC + CA yields a pliable biopolymer. The differences in drying regimes and coating layers of CMC + CA have a significant effect on the coated cotton thread strength and absorption capability. The study concluded that the IR drying regime is more effective to dry a single-layered cotton thread with a single layer of CMC + CA coating to enhance desirable properties for wound dressing modification.

“…Other researchers reported that spraying a NC suspension on solid surfaces represent a valid alternative technique to vacuum filtration to obtain high-quality thin films. Therefore, spraying offers significant advantages in specialized applications, such as contouring or contour coating (the coating solution freely falls across the substrate and forms a curtain, which follows the substrate contours) and contactless coating (no mechanical contact takes place between the base substrate and the distributor of the coating solution), especially because a high NC content can be usedthan in vacuu-filtration, hence reducing the amount of water to be removed by drying [19,20].…”

The Use of Nanocellulose in Edible Coatings for the Preservation of Perishable Fruits and Vegetables

2021

View full text Add to dashboard Cite

The usage of edible coatings (ECs) represents an emerging approach for extending the shelf life of highly perishable foods, such as fresh and fresh-cut fruits and vegetables. This review addresses, in particular, the use of reinforcing agents in film-forming solutions to tailor the physicochemical, mechanical and antimicrobial properties of composite coatings. In this scenario, this review summarizes the available data on the various forms of nanocellulose (NC) typically used in ECs, focusing on the impact of their origin and chemical or physical treatments on their structural properties (morphology and shape, dimension and crystallinity) and their functionality. Moreover, this review also describes the deposition techniques of composite ECs, with details on the food engineering principles in the application methods and formulation optimization. The critical analysis of the recent advances in NC-based ECs contributes to a better understanding of the impact of the incorporation of complex nanoparticles in polymeric matrices on the enhancement of coating properties, as well as on the increase of shelf life and the quality of fruits and vegetables.
