Inclusion complex of lemongrass essential oil with γ-cyclodextrin: preparation, characterization, and its impact on...

Mango, a nutritious fruit grown in tropical regions, is vulnerable to fungal diseases that can significantly compromise its post-harvest quality. To address this challenge, our study concentrated on the creation of an inclusion complex involving lemongrass essential oil (LEO) and γ-cyclodextrin (γ-CD) through the co-crystallization method, referred to as LEO-γ-CD. The complex was characterized using standard analytical techniques, and its effectiveness in preserving mangoes was evaluated. Results confirmed successful complex formation. Application of LEO-γ-CD at a concentration of 10 mg/g of mango extended the shelf-life by an impressive 33.33%, concurrently reducing the occurrence of rot on the fruit skin. Further analysis of key physical and chemical parameters revealed that the LEO-γ-CD significantly improved overall fruit quality, demonstrated by reduced weight loss, greater firmness, minimal changes in peel coloration, enhanced sweetness, and elevated vitamin C levels. These findings highlight its potential as a natural and effective preservative for post-harvest mango preservation.
