Special Issue Information

Dear Colleagues,

(1) The sustainability of the food system is one of the key goals for a sustainable society. The global population is growing, and, as a consequence, the carbon footprint of food-processing technologies is increasing. On the one hand, these technologies try to meet the population’s demands by processing more food, but, on the other hand, they use a huge number of resources such as water, raw materials, and energy, contributing to a negative environmental impact. However, there are new trends resulting from consumers’ concern about climate change and health. Consumers are now changing their diets, demanding natural and healthier food products, associated with cleaner and more sustainable technologies. The European Commission have introduced the Circular Economy Action Plan (CEAP), using a Farm to Fork strategy for a fair, healthy, and environmentally friendly food system.

(2) The aim of Special Issue is to explore new methods in food technology and food research which permit the sustainability of the food system. New methods need to valorize all the resources from raw materials, industry practices, provide low pollution packaging and food transportation options, and reduce wastes from retailers by calibrating all the parameters used in food preservation to obtain functional foods or innovative foods.

(3) Suggest themes.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Antioxidant substances extracted from fruit and vegetable wastes;
  • Biodegradable film as active packaging;
  • Microencapsulation methods for new foods;
  • Barrier-enhanced or active packaging materials;
  • Natural sources of pigment;
  • Agricultural practice to reduce food wastes.

We look forward to receiving your contributions.

This article examines the relationship between household food waste and Gross Domestic Product (GDP) in various European regions, aiming to determine how economic prosperity influences the levels of household food waste. Using comparative analysis of secondary and tertiary data, a synthetic indicator (IpFW) was developed to assess the interaction between GDP per capita and household food waste per capita. Linear correlation analysis was also applied for better interpretation of the data. Despite expectations, higher GDP is not consistently correlated with lower household food waste, challenging economic prosperity and environmental stewardship assumptions. This research highlights the complexity of the interaction between economic factors and household food waste management, revealing a lack of significant correlation even at the regional level. The findings indicate a need to re-evaluate current policies and highlight that improving food supply chains and influencing consumer behavior can promote more sustainable consumption patterns, which is in line with the Sustainable Development Goals.

Understanding the motivation behind consumers’ packaging choices is crucial to providing insights for achieving environmental sustainability outcomes. Here, we examined the influence of product attributes (packaging type, packaging claim, product claim, and price) and consumers factors (e.g., diet type, demographic information) driving orange juice selection. Participants residing in the USA (n = 847) responded to an online survey including: (1) a check-all-that-apply (CATA) to valued beverage characteristics question; (2) a choice-based conjoint task with packaging type, packaging claim, product claim, and price as the attributes; (3) a question tasking respondents to rank packaging material from their perception of the least to most sustainable; and (4) demographic questions. The conjoint analysis revealed that price was the most important attribute, particularly the lowest price. This study revealed that the most ideal orange juice option was packaged in glass, labelled as 100% recyclable, locally produced, and priced at $1.10 per 12 fl. oz. Not only was glass the most preferred packaging type, but it was also incorrectly perceived as the most sustainable. The intention to purchase sustainable packaging was the most important predictor of attribute relative importance (RI) and packaging utilities, followed by effectiveness perception, which only predicted the RI of price. Thus, for consumers to make more sustainable choices, education initiatives need to direct consumers to more sustainable, yet affordable, choices, while considering that purchase intention and effectiveness perception are key attitudinal drivers.

The global food system is currently facing significant challenges that make it unsustainable and environmentally harmful. These challenges not only threaten food security but also have severe negative impacts on the environment. Efforts have been made to reform agrifood systems and align them with the built environment, but emerging obstacles have revealed the weaknesses in these systems, particularly in less self-sufficient countries. This review outlines the primary environmental problems associated with global agrifood systems and the challenges in promoting food security. It emphasizes that the increasing global population and urbanization need rational and equitable changes in food systems, including production, distribution, storage, and consumption. These changes should aim to minimize environmental impacts by protecting and efficiently utilizing natural resources such as air, water, soil, and biodiversity, reducing food loss and waste, and mitigating pollution that contributes to ecosystem degradation and climate change. In this context, hydroponics emerges as a sustainable, plant-based food production technique that can be employed as a solution in urban areas. It can be implemented in domestic microproduction systems, serving as a complementary alternative to conventional food production methods. This study also provides insights into the challenges that need to be addressed in order to enhance home hydroponic systems. The integration of hydroponics into urban food production offers the potential to tackle both food security and environmental sustainability issues, providing a path toward more resilient and efficient food systems.
