The goal is to evaluate environmental impacts, identify hotspots, and propose improvements. Osmotic dehydration is the main contributor to environmental impact, particularly due to the energy and resources required by apple juice as the osmotic agent. It contributes up to 0.64 kg CO 2 eq. per kg of blueberries, 1.36 kg CO 2 eq. per kg of raspberries, and 0.66 kg CO 2 eq. per kg of strawberries. The edible coating, however, has minimal environmental impact due to its low energy consumption and biodegradable materials. Packaging has a lower carbon footprint but contributes more to fossil fuel depletion and human toxicity. Raspberries show the highest human health impact (3.5 ×10−6DALY/kg) and ecosystem impact (9.5 ×10−8species.yr/kg) , followed by strawberries (1.78 ×10−6DALY/kg, 4.97 ×10−8species.yr/kg ) and blueberries ( 1.7 ×10−6DALY/kg, 5.1 ×10−8species.yr/kg ), highlighting the greater environmental and health costs of raspberries. Despite the environmental burden of osmotic dehydration, it offers economic benefits by extending the shelf life, reducing losses, improving supply chain efficiency, and enhancing product quality, which leads to higher prices and profit margins. The study concludes that, while the environmental impacts of osmotic dehydration should be optimized, its economic and logistical benefits make it a promising preservation solution. Further research into eco-friendly practices is recommended to reduce ecological costs while maintaining commercial advantages.

Introduction Modern lifestyles are intricately linked to dietary habits, with fruits and vegetables being integral components of a healthy diet due to their abundance of bioactive compounds [ 1 ]. Berries are a valuable component of a healthy diet, known for their rich nutritional profile, including essential vitamins (C and K), minerals (manganese and potassium), and bioactive compounds such as flavonoids and anthocyanins [ 2 ]. These phytochemicals offer potent antioxidant and anti-inflammatory benefits, supporting heart health, brain function, and reducing the risk of chronic diseases like diabetes and cancer [ 3 , 4 ]. Due to their low-calorie content and natural sweetness, berries are increasingly popular among health-conscious consumers [5,6]. The shelf life of berries is a crucial factor in ensuring their availability and minimizing losses throughout the food supply chain. Due to their high perishability and rapid deterioration, berries are particularly susceptible to spoilage, which leads to significant food Foods 2025,14, 1167 https://doi.org/10.3390/foods14071167
Foods 2025,14, 1167 2 of 17 waste, especially during the transportation and storage stages [ 7 ]. The seasonal nature of berry production often results in periods of oversupply, which, if not efficiently managed, can lead to excess product that spoils before reaching consumers [ 8 , 9 ]. The losses incurred not only affect the economic viability of berry producers but also contribute to the broader environmental issue of food waste [ 10 , 11 ]. According to the United Nations Food and Agriculture Organization (FAO), 13.8% of global food production is lost annually before it even reaches consumers, with fruits and vegetables being particularly vulnerable, experiencing a loss rate of 21.6% [ 12 ]. This loss has profound economic implications, particularly in the berry industry, where oversupply and inadequate storage systems can drastically reduce profitability [13]. To mitigate these losses, various preservation techniques have been developed to extend the shelf life of berries while maintaining their quality and nutritional value. The ability to extend the freshness of berries provides significant economic benefits, reducing the volume of product waste and improving supply chain efficiency [ 5 , 14 ]. Preservation methods such as osmotic dehydration and edible coatings are gaining attention for their effectiveness in prolonging berry freshness and minimizing spoilage. Osmotic dehydration works by immersing berries in hypertonic solutions, which reduces the moisture content and inhibits microbial growth, thus slowing down spoilage and extending the shelf life [ 15 ]. Edible coatings, typically made from natural biopolymers such as polysaccharides, proteins, and lipids, create a protective barrier that limits moisture loss, prevents oxygen ingress, and reduces microbial contamination [ 16 ]. These coatings help maintain the quality and texture of berries, extending their freshness during storage and transportation [ 17 , 18 ]. Additionally, the extended shelf life made possible by these methods not only reduces food waste but also improves the overall efficiency of the berry supply chain, allowing for better inventory management, fewer transport-related losses, and greater profitability for producers [19]. Life Cycle Assessment (LCA) plays a crucial role in evaluating the environmental impacts of these preservation methods [ 20 ]. By examining the entire lifecycle of a product or process—from raw material extraction to disposal—LCA provides valuable insights into the resource use, energy consumption, and emissions associated with different preservation strategies [ 21 ]. In the case of osmotic dehydration and edible coatings, LCA can help determine their environmental sustainability by comparing their ecological footprint and identifying opportunities for improvement [ 22 ]. This comprehensive evaluation enables the identification of the most sustainable practices within the food industry, particularly in the context of berry preservation. The aim of this study is to conduct an LCA of sustainable techniques for preserving the quality and extending the shelf life of berries. Specifically, the research analyzes the environmental impacts of osmotic dehydration and edible coatings as methods to prolong the shelf life of berries, with the primary goal being to assess the feasibility and sustainability of these technologies. This study takes a comprehensive approach to evaluating these preservation methods from an environmental perspective, focusing on their long-term sustainability and potential to reduce the ecological footprint of berry preservation. 2. Materials and Methods Life Cycle Assessment (LCA) was performed following the guidelines outlined in ISO 14040 and 14044:2006 [ 23 ], and it consists of four steps: (i) Goal & Scope Definition, (ii) Inventory Analysis, (iii) Impact Assessment, and (iv) Interpretation.
Foods 2025,14, 1167 3 of 17 2.1. Goal and Scope The Goal of the LCA analysis was to determine the effect of the implementation of mild processing methods, such as osmotic dehydration and edible coatings, in the development of innovative berries with an increased shelf-life and high nutritional value. A gate-to-gate approach was selected for the evaluation of the environmental footprint of processed berries. Specifically, the system boundaries encompass production processes from berries pickup to processing and packaging. The data utilized in this study were sourced from the GaBi professional and Ecoinvent databases, which pertain to the geographical area of the European Union 28 (EU-28). All the studies and data collected are relevant to the past five years. The Scope of the LCA analysis involves defining the goals and boundaries of the study, collecting data on resource inputs and environmental outputs throughout all stages of the life cycle, evaluating potential environmental impacts, and interpreting the results to guide decision-making and foster sustainability. The Life Cycle Assessment (LCA) was performed following the recommendations proposed by the ISO 14040 recommendations series (14040:2006 and 14044:2006) [ 23 ]. ReCiPe 2016 (H, hierarchist) was selected as a method to perform the impact assessment, with its main objective being the transformation of Life Cycle Inventory results into a limited number of environmental impact scores using characterization factors. Finally, GaBi ts software (v10.6.2.9, Sphera Solutions GmbH, Echterdingen, Stuttgart, Germany) was used for the calculation of the impact categories [24]. The ReCiPe 2016 methodology defines impact indicators at two levels: midpoint and endpoint indicators. Midpoint indicators focus on specific environmental impacts, providing detailed insights into areas such as climate change, particulate matter formation, and resource depletion. These indicators cover issues like climate change (with and without biogenic carbon), particulate matter, mineral resource depletion, freshwater consumption and ecotoxicity, eutrophication, human toxicity (carcinogenic and non-carcinogenic), ionizing radiation, land use, marine ecotoxicity, photochemical ozone formation, stratospheric ozone depletion, and terrestrial acidification and ecotoxicity. Endpoint indicators aggregate the midpoint indicators to simplify result interpretation. However, as aggregation increases, so does the uncertainty of the results. Endpoint indicators offer a broader overview of environmental impacts, assessing damage to human health (measured in Disability-Adjusted Life Years, DALY), ecosystems (measured in species.yr), and resource availability (measured in monetary terms, $). 2.1.1. Product Systems and System’s Boundaries The evaluation was conducted on the innovative berry production line with extended shelf life. The system studied includes the process of receiving, processing, and packaging berries in an innovative production line, as shown in Figure 1. Specifically, compared to conventional berries that are received and directly packaged, processing methods of osmotic dehydration and edible coating have been added to the production phase.

Process Analysis Figure 2 provides a graphical representation of the production chain, illustrating the process from start to finish. It begins with the addition of freshly harvested berries into the osmotic solution, followed by their immersion in the edible coating solution, and concludes with the packaging of the berries as the final product. Figure 2. Process of the innovative production of berries. Osmotic Dehydration Osmotic dehydration is a natural and mild method of removing water from food using osmotic solutions. Based on the principle of osmosis, the process exploits the movement of water from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane [18]. In the osmotic dehydration of berries, apple juice at 42°Brix has been selected as the optimum solution, after an optimization conducted in the laboratory regarding the dehydration kinetics, the quality characteristics of the final product, and the shelf life [25]. The duration of dehydration varies between the different types, with blueberries and raspberries at 360 min and strawberries at 200 min to achieve the optimal result. The process is carried out at 40 °C, maintaining the nutritional value and organoleptic characteristics of the berries and making it suitable for industrial application. This method helps preserve the natural texture, aroma, and flavor of the berries, as it does not require high temperatures or mechanical stresses that could damage the cell walls [26]. At the same time, osmotic dehydration reduces the need for preservatives and extensive processing, making the berries healthier and more appealing to consumers seeking naturally processed products. Finally, this method offers economic and environmental benefits, as it reduces energy and resource consumption, contributing to a sustainable and efficient production of products. Edible Coating Edible coating is an innovative technology applied in food processing, aimed at improving their quality and shelf life. This process involves coating the berries with an edible film made from natural materials such as polysaccharides, proteins, and lipids [27]. Edible coatings are designed to create a protective barrier that reduces moisture loss and prevents oxygen ingress while simultaneously protecting the berries from microbial contamination [28]. The edible coating was selected based on the evaluation of various coatings conducted by Mari et al. (2024) [29]. In their study, the coating derived from the protein of Chlorella vulgaris was identified as the most effective for enhancing the shelf life of berries. The system studied includes the process of receiving, processing, and packaging berries in an innovative production line, as shown in Figure 1. Specifically, compared to conventional berries that are received and directly packaged, processing methods of osmotic dehydration and edible coating have been added to the production phase. Packaging The berries were packaged using High-Density Polyethylene (HDPE) plastic, selected for its durability and protective qualities. The packaging was designed to minimize Figure 2.

The packaging was designed to minimize physical damage during handling, transportation, and storage. HDPE serves as an effective barrier
Foods 2025,14, 1167 5 of 17 against moisture, oxygen, and contaminants, helping to maintain the freshness, appearance, and quality of the berries over time. The material’s structural integrity ensures that the berries remain intact, reducing the risk of bruising or other damage [ 11 ]. The packaging was sealed to prevent moisture loss and exposure to air, thereby slowing down the deterioration process. HDPE’s transparent nature allows for easy visibility of the product, aiding in consumer decision-making while also providing a stable surface for labeling and branding. Furthermore, the choice of HDPE was based on its cost-effectiveness and widely recognized performance in extending the shelf life for perishable items [ 28 – 31 ].This packaging method is commonly used for fresh produce due to its effectiveness in protecting the product and facilitating handling and transport. However, the environmental impact of HDPE packaging was also considered, with a focus on exploring more sustainable alternatives for future applications. 2.1.3. Functional Unit The functional unit for the berry systems is defined as 1 kg (1 kg), while an analysis was also conducted using 1 euro (EUR) of revenue as a functional unit. 2.1.4. Assumptions and Limitations The data used for berry production in both cases is derived from experimental studies and supplemented with literature reviews to ensure accuracy and represent the current industry conditions. This study primarily aims to assess the environmental footprint of the proposed methods and evaluate their feasibility for managing solid and liquid waste. Additionally, energy consumption is carefully considered, particularly in the osmotic dehydration process, where the highest energy losses occur. 2.1.5. Data Requirements For the collection of data and the establishment of the inventory, values were obtained from experiments conducted by our research team between 2021 and 2024. These experimental data were combined with relevant literature data, and all figures were appropriately adjusted and verified through direct communication within the team. 2.2.
