Abstract The growing demand for increased fresh food shelf life as well as the need of protection against foodborne diseases urged the development of antimicrobial food packaging. Among the most efficient methods, the combination of organic–inorganic, packaging, i.e. polymer embedded metal nanoparticles proved to be highly effective. Silver nanoparticles (AgNPs), in particular, have antimicrobial, anti-fungi, anti-yeasts and anti-viral activities and can be combined with both non-degradable and edible polymers for active food packaging. The actual application of AgNPs in food packaging is regulated by EU and USA food safety authorities in a prudent way, due to the inability to make conclusive statements on their toxicity. Therefore, their use is evaluated in terms of Ag+ migration into the packed food. In this mini review, the most recent studies are reported on protection of meat, fruit and dairy products against the most common food pathogens by AgNPs-doped non-degradable and edible polymers and oils are reported.

Abstract Transducing bacteriophage and gene transfer agents (GTAs) are constrained by the structural limits of their capsids, which determine the maximum length of host DNA they can package. Here, we utilise nanopore sequencing of intact, capsid-packaged DNA molecules to recover full-length reads, thereby enabling the precise identification of encapsidated DNA and its bacterial origin. This approach was validated using well-characterised transducing systems and subsequently applied to faecal viromes from three healthy donors. Our analysis reveals that bacterial DNA encapsidation is widespread in the gut microbiome, with up to 5.4% of capsid-packaged DNA derived from bacterial genomes. Generalised transduction and GTA activity were especially prominent in Oscillospiraceae and Ruminococcaceae (e.g. Faecalibacterium spp.), while lateral transduction was observed in Bacteroides. Additionally, we detected induction of prophages in several highly prevalent gut bacterial taxa. These findings reveal the prevalence of bacterial DNA packaging via virus or virus-like capsids in the human gut, shedding light on the diverse mechanisms that drive this process.

Low-density polyethylene (LDPE) is commonly used as food packaging material because of its affordability, convenience and versatility. However, there are concerns regarding the chemical migration of contaminants into food especially at high temperatures, and thus requires further investigation. The study documented the total residual contaminants (TRCs) that migrate into fatty and oily foods from LDPE food contact articles (FCAs) that are sold in the Philippines to fill a major gap in the country’s regulatory system. The study compared two international standard methods 21 Code of Federal Regulations (CFR) Part 177 and Japan External Trade Organization (JETRO 2009)—to assess their suitability for local applications. The researchers collected and analysed 23 LDPE samples across Mega Manila to estimate residue concentrations. Results indicate that TRC levels of FCAs exhibited statistically significant differences among the collection sites which may be influenced by factors such as environmental exposure, transportation and handling. Samples with the lowest and highest TRC concentrations from the 23 LDPE samples were selected for the comparative studies of the two international methods. Each low- and high-level sample underwent analysis using the testing conditions of both methods. A comparative analysis using paired t-test revealed distinct variations between the methods, with US 21 CFR giving higher concentrations at low-level samples (9.34 mg/L TRCs), and JETRO 2009 at high-level samples (19.6 mg/L TRCs). Statistical validation confirmed these differences, highlighting the need for rigorous method validation and harmonization of international and local testing standards. These findings also highlight the significance of the development of regulatory frameworks and robust testing methods that are specific to the Philippines’ environmental and industrial conditions in order to ensure food safety and enhance the country’s global competitiveness.

With the increasing application of terahertz technology in modern military, communications, and automotive radar systems, the need for miniaturized and highly integrated terahertz transceiver designs has become more critical.The ability of terahertz solid-state power combining technology to achieve high power and miniaturization is crucial for system performance. This paper investigates circuit design methods for miniaturized, high-power terahertz transmission front ends and explores packaging integration for advanced monolithic power chips. A three-dimensional stacked integration scheme is employed, comprising a W-band four-channel combining amplifier, a W-band mixing transmission front-end module, and a W-band medium-power drive module. The core modules are integrated into a compact assembly (≤4 cm ^3 ), serving as the key radio frequency (RF) component for a miniaturized W-band solid-state transmitting system. The W-band power synthesis layer achieves a saturated output power exceeding 6.8W and a power density greater than 283 mW cm ^−13 , enabling a complete transmission front-end with the W-band antenna. This design meets the requirements for a miniaturized, high-power terahertz transmission front end, offering potential applications for future high-integration, high-power systems.

The requirements towards packaging and articles intended to come into contact with food are systematically growing. Due to the growing consumer interest in consumption of fresh products with extended shelf life and controlled quality, manufacturers have to provide modern and safe packaging. It is a challenge for the food packaging industry and also acts as a driving force for the development of new and improved concepts of technology packaging. It is in order to meet these needs that active packaging can be applied. This article presents a new generation of packaging, which allows to maintain and even improve the quality of the packaged product, which is an essential advantage particularly in the food industry. It is to this end that the role and the application of active packaging were discussed. Among the solutions belonging to the active packaging, there are oxygen and moisture scavengers, ethylene regulators, and antimicrobial packaging. Active packaging is an excellent solution for a wide range of applications in the food industry. The most important advantage resulting from their use is reduction in loss of food products due to extension of their shelf life. Active systems are the future direction for development of food packaging and their commercial success should be expected in the coming years. It will undoubtedly result from constantly improved technologies of their production and the knowledge about mechanisms of their functioning and the effectiveness of their operation in ensuring food safety accumulated by both producers and consumers over time.

Background: A package insert is a document within a medication package that provides information about the product. Labels similarly covey information regarding the product but are printed on the packaging rather than separately within. Aims and Objectives: This study aimed to determine whether pharmaceuticals in India adhere to the national guidelines laid down by CDSCO with regards to the packaging and labeling of drugs. Materials and Methods: 100 drugs (labels + package inserts) were collected within duration of 1 month, beginning June 6th, 2023,–July 5th, 2023, from the central drug store of a tertiary care government hospital and nearby pharmacies. After entering pertinent data into a Microsoft Excel sheet, analysis was carried out using descriptive statistics. Results: Most companies (in and around 70%) followed requirements with respect to drug labels barring "warning about the drug" and use of the "red line," while package inserts showed divisive results, with patient-centric information such as posology, special warnings, and contraindications being followed by more than 80% of the manufacturer's while taking a backseat with regards to technical details such as shelf life and incompatibilities. Conclusion: Labels and package inserts do largely convey the information that they intend to, with scope for improvement from both companies and regulatory authorities in order to perfect the balance of information conveyed.

Expanded polystyrene (EPS) polymers are widely used in insulation and packaging applications. If their waste hasn’t been managed well and due to their long degradation time, they will cause severe environmental problems for human beings, plants, and animals. Therefore, recycling could be one of the acceptable solutions to overcome such problems in addition to reinforcing them to recover the decay in properties resulting from recycling. In this work two types of EPS have been recycled at different temperatures from 140 to 260°C, and then reinforced by E-glass fibers in mat form and as random short fibers with varied composition from 5 to 25 wt%. The samples have been prepared by homemade thermal press and the tensile properties such as strength, modulus, and ductility have been investigated showing an obvious enhancement of these properties upon an increase in temperature to certain level and with fiber content and length exceeding their critical lengths. Furthermore, interfacial adhesion has been stud-ied by estimating the strength and modulus efficiency factors. The results show that the E- glass fibers could im-prove the strength with more than 300%.

Abstract Novel food packaging technologies arose as a result of consumer’s desire for convenient, ready to eat, tasty and mild processed food products with extended shelf life and maintained quality. Recent trend of lifestyle changes with less time for consumers to prepare foods posed a great challenge toward food packaging sector for the evolution of novel and innovative food packaging techniques. The novel food packaging techniques, viz. active packaging, intelligent packaging and bio active packaging which involve intentional interaction with the food or its surroundings and influence on consumer’s health have been the major innovations in the field of packaging technology. These novel techniques act by prolonging the shelf life, enhancing or maintaining the quality, providing indication and to regulate freshness of food product. The advancement in novel food packaging technologies involves retardation in oxidation, hindered respiratory process, prevention of microbial attack, prevention of moisture infusion, use of CO2 scavengers/emitters, ethylene scavengers, aroma emitters, time-temperature sensors, ripeness indicators, biosensors and sustained release of antioxidants during storage. The novel food packaging technologies besides the basic function of containment increase the margin of food quality and safety. The novel food packaging techniques thus help in fulfilling the demands throughout the food supply chain by gearing up toward persons own lifestyle. The main objectives of this review article are to provide basic knowledge of different new and innovative food packaging techniques about their way of preservative action, effectiveness and suitability in various types of foods.

Abstract Conventional food packaging materials are derived from nonrenewable fossil resources and face difficulties in disposal and recycling. The development of green and ecologically balanced food packaging materials has received much attention as a prospective solution that can partially substitute for the imperishable fossil fuel-derived plastic. Polylactic acid (PLA) is known as a promising biopolymer, and the incorporation of nanocellulose can further enhance the properties of this biopolymer. The combination of PLA and nanocellulose enables the development of a sustainable eco-friendly food packaging as PLA can be obtained from agricultural resources and nanocellulose can be extracted from agricultural waste. This critical review demonstrates the current developments, and the advantages of PLA and nanocellulose for the purpose of food packaging are introduced. The nanocellulose produced from agricultural waste is summarized along with specific references to food packaging applications. In addition, the antimicrobial agents used in PLA/nanocellulose-based packaging are discussed. Overall, greener food packaging with enhanced antimicrobial properties with a suitable combination of bio-based nanocellulose is highlighted in this review.
