“…The isolation time during the hydrodistillation process significantly affected the yield increase (YI%) for all the treatments, with a YI% of 14.5% between the CrBL-EO EUS1 and CrBL-EOE US2 treatments, 11.86% between the CrBL-EO C1 and CrBL-EO C2 treatments, 7.47% between the CrBL-EO E2 and CrBL-EO US1 treatments, and 7.07% between the CrBL-EO US2 and CrBL-EO EUS1 treatments. The importance of enzymatic treatment is in its ability to dismantle the cellular structure of the cell wall in the plant tissue and depolymerize the polysaccharides of plant cell walls [23,[35][36][37][38][39]. Hence, it would significantly increase the effectiveness of the subsequent ultrasound-microwave integrated treatment [29], thus enhancing the qualitative and quantitative (excluding yield%) quality of isolated CrBL-EO.…”

Combined ultrasound–microwave techniques and pre-enzymatic treatment (hemicellulase and cellulase) enhance essential oil isolation from Citrus reticulata Blanco (tangerine) leaves (CrBL). Subsequently, synergistic effects of modified amorphous octenyl succinic anhydride starch (OSA-MS), almond oil, and high-energy microfluidics were studied in synergy with ultrasound techniques in the production of CrBL essential oil (CrBL-EO) nanoemulsion (CrBL-EONE). GC–MS was used to study the extraction technique. Dynamic light scattering (DLS) analysis was used with confocal laser scanning microscopy (CLSM) techniques to investigate the nanoemulsion matrices’ physical and chemical properties. The D-limonene nanoemulsion (D-LNE) reached the optimal size of droplets (65.3 ± 1.1 r.nm), polydispersity index (PDI) (0.167 ± 0.015), and ζ-potential (−41.0 ± 0.4 mV). Besides, the CrBL-EONE obtained the optimal size of droplets (86.5 ± 0.5 r.nm), PDI (0.182 ± 0.012), and ζ-potential (−40.4 ± 0.8 mV). All the nanoparticle treatments showed significant values in terms of the creaming index (CI%) and inhibition activity (IA%) in the β-carotene/linoleate system with a low degradation rate (DR). The current study’s findings showed that integrated ultrasound–microwave techniques and pre-enzymatic treatment could enhance the extraction efficiency of the CrBL-EO. In addition, OSA-MS and almond oil can also be employed to produce CrBL-EONE and D-LNE.

“…However, based on our knowledge, only a few works have been published that used the extraction of DESs and cloves. In the work of Chen et al [69], DESs were used as pretreatment solvents; they were combined with microwave-assisted hydrodistillation for the extraction of essential oils from the clove buds. They used five DES systems (Choline chloride Fructose 1:2; Choline chloride Lactic acid 1:2; Choline chloride Glucose 1:2; Choline chloride Phenol 1:2; Choline chloride Ethylene glycol 1:2) and the most suitable was evaluated system chloride and lactic acid (1:2).…”

Utilizing a deep eutectic solvent-like mixture such as choline chloride and lactic acid in a 1:2 molar ratio, clove buds underwent extraction. Furthermore, the determination of the primary components in the clove extracts, namely eugenol, eugenol acetate, and β-caryophyllene, was conducted using the HPLC-DAD method. The total phenolic content (TPC) was also established. Extraction conditions using choline chloride and lactic acid encompassed variables such as extraction temperature (within the range of 40 to 80 °C), water addition (ranging from 5.6 to 40%), and extraction time (ranging from 30 to 90 min). Optimal operational conditions for TPC were pinpointed at 77 °C, 30 min, and a water addition of 40%. The findings showed that clove extracts obtained at 60 °C, 22.8%, and 30 min had the highest amount of eugenol (307.26 ± 8.44 mg/g dry raw material).
