This research reviews methods for producing valencene, a valuable citrus-scented compound, using engineered microorganisms instead of extracting it from citrus fruits. This work impacts everyday life in several ways: • Enables more sustainable and efficient production of natural flavoring used in beverages, foods and fragrances • Helps reduce reliance on citrus crops for valencene production • Provides potential new ways to create natural insect repellents • Could lead to more affordable and accessible citrus flavoring products • Demonstrates environmentally-friendly manufacturing methods for common consumer products
