Raspberry ketone (RK, 4-(4-hydroxyphenyl)-2-butanone), a naturally occurring phenolic compound responsible for the characteristic aroma of raspberries, has attracted significant interest due to its wide applications in the food, fragrance, and health industries. While traditional extraction from fruits is limited by low natural abundance and chemical synthesis raises sustainability concerns, microbial production through precision fermentation offers a promising alternative to address these challenges.
