Recent advancements in food packaging have transitioned from passive containment toward innovative smart systems that integrate active and intelligent functionalities to improve product preservation, safety, and consumer interaction. This review examines the evolution of these technologies, focusing on biodegradable polymers and nanomaterial-enhanced substrates that combine environmental sustainability with superior barriers and antimicrobial performance. Developments in embedded sensing systems, including chemical, temperature, and humidity sensors, enable the continuous monitoring of food quality and environmental conditions, supporting extended shelf-life and early contamination detection. Intelligent packaging further incorporates indicators, sensors, and data carriers that enhance transparency and traceability across supply chains. These systems are often connected through blockchain and Internet of Things (IoT) platforms for real-time data analysis. The review also addresses consumer engagement via interactive labels and personalized nutritional feedback, along with the economic, behavioral, and regulatory aspects influencing large-scale adoption. Life cycle assessments are analyzed to evaluate trade-offs between enhanced functionality and environmental impact, emphasizing recyclability and end-of-life strategies within circular economy frameworks. Finally, the article discusses current technical challenges while highlighting emerging trends such as AI-driven predictive analytics and IoT-enabled connectivity as key enablers of sustainable, efficient, and safe food packaging systems.

The production performance and meat quality of the slow-growing hybrid Hubbard JA757 were monitored under conditions of diets differentiated by crude protein content. A total of 1200 as-hatched day-old chickens were equally and randomly allotted into two treatments (T-1 and T-2), with six replicates provided for each treatment (100 chickens/replicate). T-1 chickens received standard diets (according to Hubbard Company recommendations), and those in T-2 were fed diets supplemented with crude protein (+0.5% CP in the growing phase and +1.0% CP in the finishing phase). At the end of the investigations (age 56 days), the T-2 chickens performed better than the T-1 chickens for growth traits (+2.72% body weight; +2.77% daily growth gain; −0.34% mortality; and −4.15% feed conversion ratio); for slaughtering (+0.66% dressed yield; +1.10% breast weight; and +1.25% thigh weight); and for quality meat (+0.55% dry matter in thigh muscles and +1.52% dry matter in breast muscles) (p > 0.05). Statistically significant differences (p < 0.05) occurred between treatments for body weight, daily weight gain, and feed conversion ratio due to the 0.5% CP feed supplementation during the 15–28 day age period, justifying the usefulness of the CP increasing throughout the grower diet only and not during the finishing period.

Melatonin is a natural hormone synthesized mainly by the pineal gland of vertebrates, and, secondarily, by other tissues and organs as well. It is deemed a bioactive molecule due to the multiple roles and functions it performs in animals and humans. Research conducted up to 2024 has reported the presence of melatonin in a wide variety of plants and bacteria, as well. This review aims to collect some of the scientific data to identify and describe the main sources of melatonin, and to document the functions and roles it plays in animal organisms. It also includes a description of the main technological and nutritional factors that can positively or negatively influence the synthesis and secretion process of melatonin, which is subsequently transported from the animal body into some food products, such as milk. This paper also includes information on the interaction between melatonin and other bioactive compounds present in animal and human bodies, with the aim of identifying what other functions and roles this hormone performs, and whether it interacts with other substances present in the vertebrate organism.

This paper explores an important issue, namely rural tourism, by analyzing the supply and demand of tourism in three rural regions (Gura Humorului, Câmpulung Moldovenesc, and Dorna) in Bucovina, Suceava County, as an alternative economic development for rural areas. The statistical data on tourist traffic in the three regions of Suceava County were taken from the website of the National Institute of Statistics of Romania and analyzed over a period of 10 years (2014–2023). The analysis of the total number of tourist accommodation facilities recorded increases of over 200% in all three regions analyzed. Dynamic analysis of the accommodation capacity in operation, the number of tourists and overnight stays, and the average length of stay was carried out by calculating the absolute and relative indicators with fixed and chained base and average indicators. Despite the increase in the number of tourists and overnight stays, the average length of stay remains relatively low. The calculation of the net utilization rate of the accommodation capacity in operation shows an efficient use of the accommodation facilities in the three regions analyzed. The importance of the research and the originality of this research are closely related to understanding the dynamics of tourism in the rural regions analyzed for the formation of future strategies for sustainable rural development in Bucovina.

Quantitative and qualitative flesh production in the Silurus glanis species was comparatively studied between two fish groups: one from aquaculture (AG) and the other from a natural environment, the Prut River (RG). Morphometry was carried out on the fish, and then biometric and conformational indices were calculated. Better values were found in the aquaculture catfish. The Fulton coefficient was 0.82 in the Prut River fish and 0.91% in the farmed ones. The fleshy index reached 19.58% in the AG fish and 20.79% in the RG fish, suggesting better productive capabilities in the AG fish. Postslaughter, the flesh yield and its quality were assessed at different moments throughout the refrigeration period (0–15 days), and chemical compound loss occurred. In the AG samples, the water content decreased by 8.87%, proteins by 27.66%, and lipids by 29.58%. For the RG samples, the loss reached 8.59% in water, 25.16% in proteins, and 29%in lipids. By studying the fatty acids profile and sanogenic indices, good levels of PUFA (31–35%) were found, and the atherogenic index reached 0.35–0.41 while the thrombogenic index ranged between 0.22 and 0.27. Consequently, it can be stated that fish origin and especially the refrigeration period influence the flesh proximate composition and nutritional value of European catfish.

The aim of this research was to evaluate some characteristics (moisture, total solid substances, specific gravity, pH, FA, ash, electrical conductivity, TPC and TFC, potassium, calcium, magnesium, sodium, phosphorus, zinc, copper, manganese, nickel, cobalt, and lead) of fifteen multifloral honey samples. The quality of the investigated honey was confirmed by the obtained results: moisture, FA, and EC values were below the limit value regulated by the legislation. The average content of total polyphenols and total flavonoids of 29.91 mg GAE/100 g and 2.13 mg QE/100 g confirm the antioxidant properties of honey. Determination of minerals showed that potassium (101.4–1212.6 mg kg⁻¹) was the most abundant mineral in honey, followed by sodium (40.7–302.3 mg kg⁻¹) and calcium (41.8–230.9 mg kg⁻¹). Lead was found in two samples, with a content under the limit stipulation by legislation; nickel was found in one sample of 0.10 mg kg⁻¹, and the content of cobalt was below the detection limit. Significant correlations (p < 0.001) were observed between mm Pfund and electrical conductivity, TPC, TFC, P, Ca, and Zn; strong correlations (p < 0.001) were between electrical conductivity with Ash, TPC, TFC, K, and P. FTIR analysis confirmed the differences obtained by analyzing multifloral honey samples.
