Physiological quality of Passiflora edulis Sims seeds evaluated by different processing methods, storage times and packages

ABSTRACT Maintaining seed vigour during the storage process is essential for the success of germplasm banks of sexually propagated species such as Passiflora edulis. However, the literature is still scarce regarding efficient preservation methods, especially for long periods. The objective of this study was to evaluate the effect of different seed processing methods, types of packaging and storage conditions of Passiflora edulis seeds for a period of five years. Different seed processing methods (natural fermentation and use of a mixer), packaging (Falcon tubes, plastic bags and paper bags), storage temperatures (room temperature, cold chamber and refrigerator) and evaluation times (one, three and five years) were analysed. Seeds stored in a refrigerator and cold chamber maintained high germination (>90%) for up to five years. However, seeds stored at room temperature reduced their viability after one year of storage. No significant variations were observed between the seed processing and packaging methods evaluated. Absence of respiratory activity was confirmed by the tetrazolium test performed on seeds stored for five years at room temperature. To maintain the vigour of P. edulis seeds, it is recommended to store them in a cold room or refrigerator in different packaging and using different methods for seed extraction.

Effects of Different Packaging Types and Storage Periods on Physicochemical and Antioxidant Properties of Honeys

Preserving the nutritional value of honey without compromising its properties until consumption is crucial. However, different types of honey may respond differently to packaging and storage conditions. This study aimed to assess the effects of different packaging materials (tin cans, light-colored glass jars, and dark-colored glass jars) and storage durations (initial, 6 months, and 12 months) on the physicochemical and antioxidant properties of pine, flower, and thyme honey. Nine samples were collected to conduct study on the three different types of honey. Honey samples were packaged in these materials and analyzed at the start, after 6 months, and after 12 months. The results showed that the moisture, proline content, sugar, total oxidant status (TOS), and oxidative stress index (OSI) levels were unaffected by honey type. Over time, there was a decrease in moisture, pH, proline content, diastase number, sugar, total phenolic content (TPC), total antioxidant status (TAS), and catalase (CAT) activity, alongside an increase in the electrical conductivity, hydroxymethylfurfural (HMF), free acidity, TOS, and OSI levels. The packaging type did not influence the moisture, pH, electrical conductivity, proline content, diastase number, sugar, HMF, TPC, TAS, TOS, OSI, or CAT activity levels. The findings suggest that storing pine, flower, and thyme honey in light- or dark-colored glass jars or tin cans for 12 months does not significantly impact these properties. However, given the reduction in TPC and TAS across all honey types and packaging methods after 12 months, further studies are needed to explore ways to maintain honey quality in this regard.

Effect of Extracted Walnut Pomace Cake Edible Coating and Packaging Type on Quality Parameters of Walnut (Juglans regia L.) Kernels During Long Storage Periods

Walnuts are highly valued for their rich nutritional content, but their quality degrades during storage due to oxidation and other quality reducing processes. This study investigated the use of bioactive compounds extracted from walnut pomace, a by-product of walnut oil production, to develop an edible coating that extends the shelf life of ‘Milotai 10’ walnut kernels. Walnut kernels were stored for eight months in four different packaging materials (PE, PP, MPP, PLA) and three treatments were used (air or without treatment, nitrogen gas, and walnut pomace extract coating). The effects of these combinations on walnut quality parameters, including polyphenol content, vitamin E, fatty acids, peroxide value, and color, were analyzed. The results show that the combination of metallized polypropylene packaging under nitrogen treatment or with atmospheric air and walnut pomace extract (MPP-A-E+) best preserves walnut quality, making it a promising option for extending shelf-life.

Investigation of battery safety states based on thermal propagation and expansion analysis: Experimental studies on different packaging forms

Lithium-ion batteries are highly susceptible to thermal runaway under harsh conditions, posing significant safety risks for electric vehicles. The differences in thermal runaway propagation across battery systems with varying manufacturing methods (including packaging and internal stacking) and the study of changes in expansion force within battery modules are crucial for improving safety and developing early warning systems for battery systems. This study investigates the thermal runaway and propagation behavior of lithium-ion batteries under various conditions, focusing on state of charge (SOC), internal manufacturing processes (electrode stacking and winding), and packaging types (pouch and prismatic) through a series of novel experiments. The results show that batteries at high SOC levels are at a greater risk of thermal runaway propagation, with winding pouch cells displaying more severe runaway behavior. In contrast, prismatic cells, despite experiencing intense explosions with an equivalent force of up to 42.3 g of TNT, exhibit relatively milder propagation. Furthermore, the study incorporates heat transfer analysis during thermal runaway propagation, identifying key phenomena such as the formation of negative pressure zones before explosions and changes in expansion forces at the module level. Based on these findings, a new safety evaluation method is proposed to assess the risk, hazards, and severity of thermal runaway, offering valuable insights for enhancing battery safety management and fire prevention strategies.

Quality changes of durian pulp (Durio ziberhinus Murr.) in cold storage

Abstract In this study, the effects of four types of polystyrene (PS) plastic box with polyethylene terephthalate (PET) lid (PSPET), PS tray with polyethylene (PE) bag (PSPE), PS tray with a vacuumed PE bag (PSVPE), and PET box with a sealed lid (PET) on the quality of durian fruit during storage at 10°C were investigated. The analysis results showed that in all four types of packaging, the total aerobic bacteria count in the durian pulp ranged from 101 to 105 CFU/mL after storage. However, total yeast and mold count was not detected. During the same survey period, PET packaging for the product had the lowest weight loss of 0.58–3.07%. Next, the impact of temperature, at 0 and 10°C, on the quality stability of durian fruit during storage was also studied and evaluated. Durian pulp preserved in PET at two different cold temperatures did not show any significant difference in microbial content and phytochemical composition. Total aerobic bacteria count in the samples was recorded at about 104 CFU/g after storage; total yeast and mold count was not detected, and the weight loss reached 1.82 and 1.72% at temperatures of 0 and 10°C, respectively.

Study of quality indicators of white amaranth bread during storage

A study was carried out on the moisture content, porosity, acidity, and crumbling of bread made from fi rst grade wheat baking fl our with the addition of amaranth extrudate fl our. The use of various types of packaging was considered; the parameters were measured over three days.

The Application of Nanotechnology in Various Food Categories and Packaging

Nanotechnology has the potential to revolutionize the food industry by enhancing safety, quality, and shelf life. However, public acceptance is crucial for successful commercialization. This study provides a comparative analysis of consumer perceptions, attitudes, and willingness to purchase nanotechnology-based products across various food categories (processed foods, beverages, dairy, meat, fresh produce) and packaging applications (active, intelligent, biodegradable). Findings indicate that acceptance varies significantly based on food category and packaging type. Key influencing factors include perceived risks/benefits, knowledge/awareness, trust in regulations, and sociocultural/demographic variables. The study emphasizes the need for effective risk communication, transparent labeling, and public engagement to enhance consumer trust. Insights can guide policymakers, researchers, and industry in developing targeted strategies to address concerns and promote responsible nanotechnology development in the food sector.

A Viability Study of Thermal Pre-Treatment for Recycling of Pharmaceutical Blisters

Pharmaceutical packaging is one of the most used packaging types which contains aluminum and plastics. Due to increasing amounts of waste and rising environmental concerns, recycling approaches are being investigated. Since blisters usually contain a balanced amount of plastics and metals, most of the approaches focus on recycling only one material. Therefore, more sustainable recycling approaches which recover both plastic and aluminum fractions are needed. This study investigates the thermal behavior and degradation mechanisms of plastic-rich and aluminum-rich pharmaceutical blisters using various analytical techniques. Structural characterization revealed that plastic-rich blisters have a thicker profile with plastic and aluminum layers, while aluminum-rich blisters consist of plastic layers between aluminum sheets. Thermal degradation analysis showed two main stages for both types: plastic-rich blisters (polyvinyl chloride) exhibited significant weight loss and long-chain hydrocarbon formation between 210 and 285 °C, and aluminum-rich blisters (polyamide/nylon) degraded from 240 to 270 °C. Differential Scanning Calorimetry and Fourier Transform Infrared Spectroscopy analyses confirmed the endothermic behavior of such a transformation. The gas emissions analysis indicated an increased formation of gasses from the thermal treatment of plastic-rich blisters, with the presence of oxygen leading to the formation of carbon dioxide, water, and carbon monoxide. Thermal treatment with 5%O2 in the carrier gas benefited plastic-rich blister treatment, reducing organic waste by up to 80% and minimizing burning risk, leveraging pyrolytic carbon for protection. This method is unsuitable for aluminum-rich blisters, requiring reduced oxygen or temperature to prevent pyrolytic carbon combustion and aluminum oxidation.

Advancements in metal oxide bio‐nanocomposites for sustainable food packaging: Fabrication, applications, and future prospectives

AbstractThe research on metal oxide bio‐nanocomposites for sustainable food packaging has witnessed significant advancements, offering a promising alternative to traditional food packaging materials. This review briefly describes their fabrication techniques, applications, superiority over conventional packaging, challenges, limitations, and potential trends. These new materials are derived by incorporating metal oxide nanoparticles into the biopolymers and show better properties, such as better antimicrobial properties, which are vital in food packaging. The advantages of using metal oxide bio‐nanocomposites over typical food packaging films include enhanced mechanical properties, better moisture and oxygen resistance, bacterial resistance, and light protection. These versatile materials not only serve the purpose of properly preserving the quality and possibly even the wholesomeness of packed food products, but they are also environmentally friendly. Moreover, the review presents current developments and areas of use of metal oxide bio‐nanocomposites in food packaging and it also proposes future developments to meet the modern challenge of the food industry in the development of advanced packaging technologies.

Analysis of the Impact of Plastic Packaging on Food Waste Behavior in UK Households

This research is designed to analyse the impact of plastic packaging for food products on households’ food waste behaviour in the UK. The photo-elicitation approach is employed to achieve this research goal, and the sample consists of fifteen respondents in the Wales region and in particular in Bangor. As a result, this research finds that most of the respondents are in favour of a significant impact of food packaging on food waste, and most of them indicate that plastic food packaging can contribute relatively more to food waste than other types of food packaging. On the other hand, there also exist a few respondents who consider that there is no relationship between food packaging and food waste.

Interactive hygiene training using free open source software.

Regular hygiene trainings are an important way to refresh and improve knowledge about hygiene measures and the prevention of healthcare-associated infections. We aimed to develop an e-learning course to allow healthcare workers (HCWs) to learn these contents through a self-paced online format. We developed an interactive hygiene training for HCWs of a tertiary care hospital using different content types of the HTML-5 package (H5P) plugin embedded into a Moodle-based learning management system. We evaluated the course using a short online questionnaire. We present various suitable topics for online hygiene trainings as well as their implementation in an e-learning course. Examples include content on hand hygiene indications and techniques, information on multidrug-resistant organisms and other current topics in infection control. HCWs reported high overall satisfaction, perceived increase in knowledge, practical relevance as well as good usability and comprehensibility. Currently available commercial and non-commercial hygiene trainings present a number of specific advantages but also drawbacks. The presented approach combines the advantages of both approaches. The majority of the presented content can be readily adapted to suit various hospitals and care facilities or serve as inspiration for creating similar courses while remaining cost-effective. H5P course presentations are a low-threshold, cost-effective way to implement digital hygiene trainings in a wide variety of clinical settings.

Abstract To meet the need of storing the nuclear facility dismantling wastes in Taiwan, National Atomic Research Institute (NARI) plans to develop a new type of low-level radioactive waste container based on the exterior specifications of the existing C1 container but with higher payload. Currently, the design of this container has been finished, and the associated structural analyses specified in the regulations have also been done. In this article, it summarizes what NARI has performed and what NARI plans to do for the development of this container. It includes not only the information of C1 container and its actual applications but also the design specifications and the associated numerical analyses of the container under development. Based on the analysis results, the container under development satisfies the requirements of the low-level radioactive waste storage container and the industrial package type 2. Currently, NARI has entrusted a local vendor to fabricate the prototypes of this container and perform the specified tests in the second half of 2024. The usage permit application of this container will be submitted to the authority agency in the first half of 2025. Hopefully, the usage permit could be granted in 2026.

Formulation and Characterization of Deep Eutectic Solvents and Potential Application in Recycling Packaging Laminates.

Deep Eutectic Solvents (DESs) show promising abilities for the delamination of multilayer packaging films that are used in food packaging and in pharmaceutical blister packs. Due to the complexity of their structure, the recycling of such materials is a challenging task, leading to the easiest or cheapest disposal option of either landfill or incineration. Towards the development of 'green' solvents for efficient waste management and recycling, this research focuses on the preparation of a range of hydrophobic and hydrophilic DESs based on carboxylic acids in combination with various naturally derived aliphatic and aromatic organic compounds as well as amino acids. Chemical and physical characterization of the solvents was undertaken using differential scanning calorimetry, rheometry, and density measurements for the determination of their properties. Subsequently, batches of solvent were tested against different types of consumer packaging to evaluate the ability of the DES to delaminate these structures into their component materials. The laminate packaging waste products tested were Al/PE, PE/Al/PET, Al/PE/paper, and PVC/PE/Al. Separated films were collected and studied to further examine the effect of solvent delamination on the materials. Depending on the DES formulation, the results showed either partial or full delamination of one or more of the packaging materials, albeit there were challenges for certain solvent systems in the context of delivering a broad delamination efficiency. Variables including temperature, agitation rate, mixing time, and solvent ratios were investigated via a Design of Experiments process to assess the effects of these parameters on the delamination outcome. The results showed that the DESs presented in this research can offer an efficient, low-energy, affordable, and green option for the delamination of laminate packaging materials.

Can reusable packaging revolutionise e-commerce? Unveiling the environmental impact through a comparative carbon footprint analysis

E-commerce is a rapidly growing, evolving sector. Its environmental impact has also increased, with shipping packaging being a key contributor. The sector is, however, struggling to tackle this environmental impact, as well as to follow new packaging regulations. Previous studies on reusable packaging have predominantly been qualitative or concentrated on material selection, overlooking essential elements of supply chain design and consumer behaviour. Industry reports attempting to quantify the sustainability of reusable packaging have produced varied results that lack generalisability or transferability to other contexts. Consequently, it is difficult to determine the actual environmental sustainability of reusable packaging in e-commerce. In this research, we assess the carbon footprint of reusable packaging in e-commerce, through a comparison of eight case studies. A multiple case study approach is followed, employing an embedded design where more than one unit of analysis is explored in each case. We evaluate the CO2 emissions of all processes related to the circular supply chain of reusable packaging employing a method that can evaluate different solutions and situations and a sensitivity analysis. Findings highlight three specific factors influencing the carbon footprint of reusable packaging: (1) reusable packaging material, (2) return and reuse rate, and (3) supply chain design (i.e., centralised versus decentralised design, travel distance, transport mode). For the same type of reusable packaging, we found that polyester generates 215% more CO2 emissions than cardboard in production and waste management. However, by analysing the same reusable packaging and supply chain, these same emissions can drastically increase if the return and reuse rate decreases. Changes in the return and reuse rate mainly linked, among others, to customer behaviour and involvement. Furthermore, for the same reusable packaging and return and reuse rate, a decentralised supply chain can reduce the CO2 emissions compared to a centralised structure. Interestingly, reusable packaging is environmentally sustainable long before it reaches its maximum life cycle. Most of the analysed solutions were more environmentally friendly than a cardboard box when they reached 10% of their estimated life cycle.

QUALITY AND SAFETY MANAGEMENT OF FERMENTED MILK PRODUCTS FROM CAMEL MILK BASED ON HACCP PRINCIPLES

Currently, the main task of domestic producers of milk and dairy products is to provide consumers with high-quality and safe dairy products. At the same time, the main guarantee of safe production is the introduction of the HACCP system at enterprises.The main advantage of the HACCP system is error detection, namely prevention and prevention, through step-by-step control of the entire food production chain.The research work was carried out on the basis of the national standard SS RK 1179-2003 «Quality systems. Food quality management based on the principles of HACCP. General requirements». At the first stage, the necessary information about the fermented milk product from camel milk was collected (composition, organoleptic characteristics, indicators characterizing quality and safety, application, type of packaging, storage and delivery conditions) and a flowchart of its production process was compiled. At the second stage, the results of scientific research by other authors and regulatory documents related to the quality and safety of camel milk and products from it were examined to analyze chemical, biological and physical risks. Then an assessment of the probability of the identified dangerous risks was carried out. Further, using the Decision Tree tool, critical control points in the technology of the research object were identified, allowing to manage safety and improve quality in their production.

Pollen dispersal units of selected Orchidoideae and their morphological, ultrastructural, and chemical features

This study focusses on the structural diversity of pollen dispersal units and pollen wall ultrastructures within Orchidoideae, the second largest of the five orchid subfamilies. Orchidoideae are monandrous, i.e. they have only one fertile anther producing predominantly sectile pollinia. Using a variety of methods, including combined light and electron microscopy and various staining and contrasting media, this research aims to expand playnological knowledge of orchidoid pollen. The study provides new insights into pollen morphology and ultrastructure of six Orchidoideae species and compares them with previously studied epidendroid species to identify shared and/or distinctive characteristics within these subfamilies. Our findings revealed not only deviations from the classic angiosperm pollen wall depending on the pollen package type but also differences in pollen wall structures both within the Orchidoideae and compared to the Epidendroideae. Detection reactions and contrasting methods provide further insights into the chemical composition of elastoviscin, essential for pollinia/pollinaria formation, and suggest, that the term elastoviscin encompasses a range of chemically distinct substances.

On the issue of digitalization of banking services

In this article, we will identify and analyze banking services provided during the use of modern information technologies in remote customer service of the bank. The author highlights the features, issues, and prospects of the digitalization process in Ukraine. Today, dozens of banks offer their clients, both legal entities and individuals, as well as individual entrepreneurs, remote servicing systems and Internet banking, providing full banking services through the «Internet» from anywhere on the globe. Internet banking is a service that allows managing one’s bank account over the internet, offering great convenience and speed, the ability to carry out operations with one’s account, opened in one’s bank, without visiting the bank’s office and forgetting about queues at the cash desks and settlement departments of other organizations. On the other hand, internet banking is a general term for remote servicing technologies, as well as access to accounts and operations (on them), provided at any time from any computer with internet access. The article notes the lack of a unified approach to defining retail banking services, as well as a universally accepted interpretation of the concept of a «banking service.» A definition of a banking service is proposed, namely, a banking service is the result of a set of banking operations aimed at satisfying the client’s needs, bringing certain benefits to the consumer, related to the movement of financial assets or providing financial information. Accordingly, the provision of banking services is the main activity of any bank. In order to make a profit, a banking institution must create a service necessary for the client, determine its price, enter the market with it, implement it, and also ensure proper legal regulation. As a result of the study, conclusions were made that the range of banking services provided to individuals is constantly expanding. This will allow banks in the future to create various types of service packages.

Design of Experiment Applied in the Chemical Separation Process of Plastic and Aluminum Present in Aseptic Carton Packages

Objective: This study aimed to investigate the separation of polyethylene and aluminum residue layers from Tetra Pak post-consumer packaging. This was achieved by facilitating a spontaneous reaction between aluminum and water, with the assistance of NaOH as a catalyst. Theoretical Framework: Aseptic carton packaging is widely recognized as safe and high-quality in the food and beverage industry. This type of packaging offers several properties, acting as a barrier against gases, light, loss of flavor, and water vapor while providing shape and flexibility. These characteristics are achieved by combining plastic, paper, and aluminum. Despite the significant advantages of multilayer films, recycling this material presents challenges. Methodology: During the initial planning phase, a 26-2 fractional factorial experiment was conducted to evaluate 6 different process variables: agitation (rpm), pre-treatment, NaCl concentration (g/L), time (minutes), temperature (°C), and NaOH concentration (mol/L). Subsequently, a second experimental design called the Design Central Composite (DCC) was implemented. The results indicated that only temperature and time remained statistically significant. Results and Discussion: Based on the experimental results, were able to identify the most effective conditions for separating polyethylene and aluminum waste from Tetra Pak post-consumer packaging using response surfaces an optimal region can be defined with a minimum temperature of 50°C, a minimum time of 30 minutes, and a minimum NaOH concentration of 3 mol/L. Originality/Value: This study adds to the existing literature by examining the application of experimental planning techniques in the chemical separation process of plastic and aluminum in Tetra Pak® packaging through two consecutive experimental plans.

Quality of Castor the Seeds Stored in Different Environments and Type of Packaging

One of the ways to offer high quality seeds to the market is to work on better storage conditions to keep the physiological quality of the seeds high. Thus, this work aimed to evaluate the physiological quality of hybrid castor seeds during storage in different environments and packaging in the Cerrado conditions. A completely randomized design with plots subdivided over time was used, with four replications. In the plots the factorial 2x3x7 was designated, being: 2 environments (cold chamber and laboratory environment) and 3 packages (kraft paper, plastic bag and PET bottle) and in the subplots the 7 storage times (0, 2, 4, 6, 8, 10 and 12 months). The castor seeds used were from the hybrid cultivar AG IMA 110204 and were stored in the laboratory of the State University of Goiás, Câmpus Anápolis. The following tests were carried out: water content, germination test, first count, electrical conductivity, length, seedling dry mass and seedling dry mass density. The data were submitted to analysis of variance, the qualitative treatments when significant were compared by the Tukey test, while the quantitative treatments were submitted to the regression analysis. It is recommended to use both a plastic bag and a PET bottle to package AG IMA 110204 hybrid castor seeds during twelve-month storage, both in cold storage and in a laboratory environment.
