This study aimed to highlight the plant species used as food packaging in southern Benin. A survey questionnaire was administered in local markets, and informed consent was obtained from native guides. Data were processed using Google Forms, and a phytochemical screening was conducted on the sampled species. A total of 311 individuals, including elders, vendors, and consumers, participated in the survey. The most commonly used plant species identified were Tectona grandis, Thalia geniculata, Musa sapientum, Gmelina arborea, Manihot esculenta, and Terminalia catappa. Several reasons, primarily cultural, explain the preference for these species. Notably, Tectona grandis and Musa sapientum demonstrated superior morphological, physical, and organoleptic qualities, measuring 79 cm by 53.5 cm and over 2 m by 50 cm, respectively. They accounted for 33.33% and 32.35% of usage. Additionally, fermented corn paste, making up over 53% of offerings, was the most popular food item. The mechanical properties of these leaves, such as flexibility, toughness, and relative impermeability, along with identified phytochemicals like terpenes, alkaloids, gallic acid, flavonoids, and coumarins, enhance food preservation and limit microbial activity. Promoting the use of these natural packaging materials over plastic alternatives could significantly reduce environmental pollution and mitigate the risks associated with toxic microorganisms in food, contributing to both ecological health and food safety.展开更多

Among them, <em>C.</em> <em>nigrodigitatus</em> could represent, at certain periods of the year the highest biomass of the littoral ichthyofauna, accounting for 17 to 43.8% of total catches. In this paper, its diet in the hydrosystem Lake Togo-Lagoon of Aného was investigated focusing on how differences in diet and food consumption are related to size, season and sexual maturity. A total of 195 males and 137 females were sampled from January to December 2017. The digestive tract of each individual was dissected and its content was analyzed, using indexes of stomach contents analysis method. Diet variability in relation to season and biometric <em></em>parameters was also studied. About 99 stomachs were empty with an overall vacuity index of 29.82%. However, vacuity index was found to vary in relation to fish size and months. The fish has been found to be omnivorous with a carnivorous tendency consuming a wide range of prey items (H = 3.34). Juvenile and adult freshwater clams (<em>Galatea paradoxa</em>) were the numerical dominant preys (%N = 44%) while the penaeid shrimps (<em>Farfantepenaeus notialis</em>) with an annual frequency of occurrence (Fo) of 49.36% and all species confused of fish (33.91%) were the most preferred preys. The index of relative importance (IRI) reveals that freshwater clam (40.49%), penaeid shrimps (35.85%) and all species confused of fish (14.58%) were the most important preys of <em>C. nigrodigitatus</em>. The dominance of Malacostraca and Mollusca in the diet of <em>C. nigrodigitatus</em> in the hydrosystem Lake Togo-Lagoon of Aného is likely one of the more important considerations for future management plans.展开更多
