Recent Developments

Food packaging has a crucial function in the modern food industry. New food packaging technologies seek to meet consumers and industrial's demands. Changes related to food production, sale practices and consumers' lifestyles, along with environmental awareness and the advance in new areas of knowledge (such as nanotechnology or biotechnology), act as driving forces to develop smart packages that can extend food shelf-life, keeping and supervising their innocuousness and quality and also taking care of the environment. This review describes the main concepts and types of active and intelligent food packaging, focusing on recent progress and new trends using biodegradable and biobased polymers. Numerous studies show the great possibilities of these materials. Future research needs to focus on some important aspects such as possibilities to scale-up, costs, regulatory aspects, and consumers' acceptance, to make these systems commercially viable.

Historically, chemicals exceeding maximum allowable exposure levels have been disastrous to underdeveloped countries. The global food industry is primarily affected by toxic chemical substances because of natural and anthropogenic factors. Food safety is therefore threatened due to contamination by chemicals throughout the various stages of food production. Persistent Organic Pollutants (POPs) in the form of pesticides and other chemical substances such as Polychlorinated Biphenyls (PCBs) have a widely documented negative impact due to their long-lasting effect on the environment. This present review focuses on the chemical contamination pathways along the various stages of food production until the food reaches the consumer. The contamination of food can stem from various sources such as the agricultural sector and pollution from industrialized regions through the air, water, and soil. Therefore, it is imperative to control the application of chemicals during food packaging, the application of pesticides, and antibiotics in the food industry to prevent undesired residues on foodstuffs. Ultimately, the protection of consumers from food-related chemical toxicity depends on stringent efforts from regulatory authorities both in developed and underdeveloped nations.

The aim of the paper is an attempt to prepare draft about the matrix: drivers and research area in the C-PC with an intension to identify future research needs and priorities with relevance to C-PC development. The approach adopted in the paper is limited to the two terms: “drivers” and “research area”. Drivers have been selected to the research areas defined on the base of the 14thICPIC which reflect general scope of the C-PC domain. However, the identification and prioritization is not yet precise and do not define the result but try to establish the starting point. The purpose is that the paper is going to be used as a catalyst to guide discussion among the members of the C-PC community and to maximise the output in C-PC.

The Cost

The rising global consumption and industrialization has resulted in increased food processing demand. Food industry generates a tremendous amount of waste which causes serious environmental issues. These problems have forced us to create strategies that will help to reduce the volume of waste and the contamination to the environment. Waste from food industries has great potential as substrates for value-added bioproducts. Among them, polyhydroxyalkanaotes (PHAs) have received considerable attention in recent years due to their comparable characteristics to common plastics. These biodegradable polyesters are produced by microorganisms during fermentation processes utilizing various carbon sources. Scale-up of PHA production is limited due to the cost of the carbon source metabolized by the microorganisms. Therefore, there is a growing need for the development of novel microbial processes using inexpensive carbon sources. Such substrates could be waste generated by the food industry and food service. The use of industrial waste streams for PHAs biosynthesis could transform PHA production into cheaper and more environmentally friendly bioprocess. This review collates in detail recent developments in the biosynthesis of various types of PHAs produced using waste derived from agrofood industries. Challenges associated with this production bioprocess were described, and new ways to overcome them were proposed.

AbstractSingle-use plastic food packaging is a major contributor to the global solid waste problem. Although the food industry is developing strategies to reduce single-use plastic packaging, it needs to better understand consumer awareness and attitudes about the issue. As consumer awareness about single-use plastic waste outpaces private sector practices, this study considered personal motivation factors, government policies, and innovative solutions related to single-use plastic food packaging. This Canada-wide study surveyed 1014 consumers and their willingness to pay premiums for sustainable food packaging alternatives and motivations to reduce single-use plastic waste. Overwhelmingly, most (93.7%) respondents were personally motivated to reduce consumption of single-use plastic food packaging. Canadians were highly motivated to reduce single-use plastic food packaging, but less willing to pay for sustainable alternatives. While environmental concerns were more critical than food safety, Canadians acknowledged that sustainable packaging alternatives were more desirable than outright plastic bag bans, despite not willing to pay for them. Using approaches that consider multiple driving factors on consumer behavior and opinions towards use of single-use plastic food packaging, limitations, recommendations and future research are proposed.

The Impact

Although social change is diverse and ubiquitous, there is to date little research on the impact of social change on individual development, nor on the variables that may mediate and moderate this impact. This lack is, in part, based on insufficient consideration of psychological theories that may be applied to social change, but particularly on the lack of specific theories on psychological consequences of social change. In addition, methodological problems in measuring the complexity of social change have limited research on the consequences of social change on human development. With a focus on the effects of the breakdown of the communist system in Eastern Germany and Eastern Europe on individual development, the present paper analyses how prominent psychological theories can be applied to research on human development in times of social change, namely, Bronfenbrenner’s ecological paradigm, the transactional stress theory, and recent developments of lifespan theories of control and coping. A behavioural model is introduced that analyses developmental consequences of individual’s coping with social change. Finally, we discuss methodological implications for studying social change and set out future research needs.
