Current environmental and safety considerations urge innovation to address the need for sustainable high-value chemicals that are embraced by consumers. This review discusses the concept of sustainable fragrances, as high-value, everyday and everywhere chemicals. Current and emerging technologies represent an opportunity to produce fragrances in an environmentally and socially responsible way. Biotechnology, including fermentation, biocatalysis, and genetic engineering, has the potential to reduce the environmental footprint of fragrance production while maintaining quality and consistency. Computational and in silico methods, including machine learning (ML), are also likely to augment the capabilities of sustainable fragrance production. Continued innovation and collaboration will be crucial to the future of sustainable fragrances, with a focus on developing novel sustainable ingredients, as well as ethical sourcing practices.

Article Synopsis
- The yeast Pichia caribbica from the Meyerozyma guilliermondii species complex shows diverse abilities that help it adapt and survive in various environments.
- The study explored how phytic acid (PA) can improve P. caribbica's effectiveness in protecting table grapes from decay and preserving their quality, with findings indicating that PA enhances yeast growth and biofilm formation.
- Treatment with PA not only increased antioxidant enzyme activity in P. caribbica but also led to better control of grape decay during storage, demonstrating potential for sustainable postharvest solutions that consumers found appealing based on improved grape quality.

Citronellol is widely utilized in consumer products, including cosmetics, fragrances, and household items. However, despite being considered a relatively safe chemical, the health effects and toxicity mechanisms associated with exposure to high concentrations of citronellol, based on product content, remain inadequately understood. Here, we aimed to analyze the neurological effects of citronellol in zebrafish larvae using behavioral and histological analyses and elucidate the mechanisms underlying its neurotoxicity in vivo.
