Summary: The olive tree is a widely cultivated crop in Mediterranean countries, rich in antioxidant compounds like hydroxytyrosol which offer health benefits. Hydroxytyrosol has anti-inflammatory, antioxidant, antimicrobial, and anticancer properties, making it a valuable preservative agent for meat. However, its unpleasant odor and flavor can be mitigated by using synthetic sources of hydroxytyrosol.

Summary: The green synthesized OE-Ag NPs exhibited excellent antibacterial activity against different bacterial strains, comparable to standard antibiotic drugs. They also showed superior cytotoxic efficacy against MCF-7 carcinoma cells compared to plant lead extract and Com-Ag NPs. Furthermore, OE-Ag NPs demonstrated higher biocompatibility with hMSC and 293T cells compared to Com-Ag NPs. These biological results suggest that OE-Ag NPs have potential applications in various biological and nutraceutical fields, opening up new possibilities for producing biocompatible nanoparticles with enhanced biological functionalities from plants.

Summary: The food industry generates significant amounts of organic waste, and incorrect disposal can have negative environmental and economic impacts. The jaboticaba peel is a widely-used organic waste in the industry due to its sensory characteristics. This study developed a low-cost adsorbent material, using chemically activated residues from jaboticaba bark, for the removal of the cationic dye methylene blue. The results showed that the chemically activated jaboticaba bark had the highest adsorption capacity and can be a sustainable alternative for water decontamination.
