“…The results indicated that essential oils of C. maxima peels were rich in D-limonene (33.61%), β-sitosterol (17.99%), α-sitosterol (12.19%), stigmasterol (5.22%) and α-pinene (4.32%). Furthermore, several reports showed that C. maxima peels are rich in D-limonene and α-pinene as their major chemical constituents [ 43 , 44 , 45 ]. The difference in oil yields and chemical composition could be explained by genotypic variations, environmental factors, and external factors such as climate, collection time, extraction methods and soil composition [ 46 , 47 ].…”

The wastes generated during the post-harvest handling of various agricultural commodities is rather under-utlilized. The peels of citrus fruits are often discarded as waste. Citrus peels are rich in essential oils and exhibit toxicity towards various insect species. The essential oils are also an eco-friendly option for insect pest management. The Citrus maxima peel essential oil (CMEO), a waste product, characterized it, and evaluated its potential for insect pest management. The major terpenoids present in CMEO are Limonene and α-Pinene. The CMEO displayed potentials in controlling the insect pests via contact and fumigant toxicity. Moreover, CMEO showed significant larvicidal activities against Culex tritaeniorhynchus and Aedes aegypti species of mosquitoes; however, Armigeres subalbatus was more resistant. The biological safety of the essential oil was also tested against the stored seeds, where no significant inhibition of seed germination was noticed compared to the control. Utilizing a waste product such as citrus peel for pest management can achieve the dual objective of waste utilization and eco-friendly pest management. Overall, the CMEO is therefore found to be a bioactive essential oil extracted from the wastes of pomelo (C. maxima).

“…This result was due to the higher coefficient of determination. R 2 and deviation of the actual and calculated essential oils were within the allowable range (less than 5%) which was considered as a supporting factor in assessing the fit of the model [20]. More specifically, the coefficient R 2 at the optimal position (2.1 mL/min) of the model 3 was shown to obtain a high value (0.99576).…”

“…In the batch desorption system, models describing the solubility of the essential oil from the surface and diffusing the essential oil within the materials were developed to explain the desorption kinetics of the extraction process. The pseudo-first model with nonlinear regression is widely used with high compatibility to explain the mechanism of the process in solid-liquid interaction [14,15,19,20].…”

“…This in turn causes the initial increase in oil distillation rate and final essential oil yield. Moreover, the degradation of thermally unstable components can also occur during prolonged heating, reducing the yield of pomelo peel essential oil at lower steam flow rate [11,20].…”

“…The experimental kinetic curves showed the typical extraction performance, which mainly comprised of two stages: (1) rapid extraction (washing phase), in which the essential oils were located on the outer surface of the washed material and ( 2) slow extraction stage (diffusion stage), in which the essential oils localized inside raw materials moved to the external environment. The second stage is characterized by a slow process, showing the gradual improvement of essential oil yield [11,20]. The curves, showing the variations of pomelo peel essential oil yield, were sigmoid or S-shaped with upward curvature.…”

Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.
