TÓM TẮT
Melaleuca oil serves as a potent immune system booster, swiftly combating various viral, bacterial, and fungal infections. Despite its potential, Melaleuca oil production in Vietnam remains limited due to outdated techniques. This research focused on enhancing production by employing the steam explosion method prior to steam distillation for two Melaleuca species: alternifolia and quinquenervia. Steam explosion, which plays as a preliminary treatment, subjects Melaleuca material to rapid pressure changes, causing a mechanical 'explosion.' This process fractures the material's structure, facilitating essential oil migration from the interior to the surface, and significantly shortening distillation time. Experiments varying steam explosion duration (1, 3, and 5 minutes) were conducted at the steam pressure of 5 barg. With a 5-minute steam explosion, approximately 9.6 mL of essential oil was extracted from 3 kg of raw Melaleuca quinquenervia – nearly doubling traditional non-explosive methods. Moreover, distillation time was reduced by 60%. The needle-like leaves of alternifolia contributed to steam explosion's efficacy, yielding more oil. These findings underscore the importance of pretreatment in enhancing oil extraction efficiency, including yield and energy consumption
