Nutritional and medicinal assessment of seaweeds from Mozambique Juliao Monjane, Dulce Chemane, Maisha Kunchendje, Amalia Uamusse Eduardo Mondlane University, Mozambique Global demand for macro- and microalgae-based foods is growing worldwide, and seaweed is being consumed not only for functional benefits but also for nutrition and health-related benefits. There is limited knowledge about the nutritional and medicinal composition of various species of seaweed, as the geographic location and time of year in which they are harvested substantially affect their nutritional and medicinal value. The nutritional and medicinal value of the seaweed Sargassum crassifolium and Cladofora vagabunda was evaluated to determine their physicochemical and antibacterial properties. Based on the results obtained in this work, it can be concluded that algae (Cladophora vagabunda and Sargassum crassifolium) are rich in secondary metabolites. Regarding antimicrobial activity against Candida albicans and Staphylococcus aureus, the C. vagabunda demonstrated better results in inhibiting microbial growth, while the S. crassifolium alga could be used as an antioxidant agent withEC 50 values 101,403 μg/mL e 176,853 μg/mL. The nutritional values of S. crassifolium: humidity 8,633±0,234%; Total ash 23,836±4,495%; Lipids 1,495±0,212%; Proteins 0,204±0,125%; carbohydrates 65,801±3,918%; Total chlorophylls 7,2486±0,0605 μg/mL μg/mL; carotenoids 1,3735±0,1257 μg/mL. Both seaweeds have high content ofCa, Na, K, and Mg. References 1. Alexandre, J., & Arroz, H. (2016). Increase in cases of malaria in Mozambique, 2014: epidemic or new endemic pattern?
