Application of Response Surface Methodology for the Optimization of Essential Oils from Pomelo [Citrus grandis (L.) Osbeck] Leaves using Microwave-Assisted Hydrodistillation Method

Abstract

Pomelo leaves oil has many applications regarding hair nourishment and stimulation. Recently, new methods of extracting essential oil used have been increasingly developed to replace traditional methods. In this research, maximization of essential oils yield from Citrus grandis was studied by the combination of microwave assisted hydro-distillation (MAHD) and response surface methodology (RSM). We found that the maximum essential oil yield was 0.3197 % with 91.3 % desirability corresponding to factors such as material and water ratiosof 3.04:1, extraction time at 62.76 min and microwave power of 482.17 W. ANOVA analysis for quadratic model also gives favourable outcome including the high determination coefficient (R2 = 0.9443), significant F-value and p-value of coefficients. All these values indicate that this model is significant between experimental and predicted variables.

Modeling the extraction process of pomelo (citrus maxima (burm.) Merr.) Peel essential oil by steam distillation on a production scale (500kg/batch)

“…It contains minerals that support bone health and correct bone formation and the body's electrolyte balance, such as calcium, phosphorus, salt, and potassium [2,7]. In addition, new research on the fruit's various components, such as its pulp, peel, leaves, seeds, and essential oils, may uncover additional pharmacological actions that could be helpful to people [8][9]. Pomelos have a low percentage of edible sections, one of its issues (being fruit pulp).…”

Central Composite Design, Kinetic Model, Thermodynamics, and Chemical Composition of Pomelo (Citrus Maxima (Burm.) Merr.) Essential Oil Extraction by Steam Distillation

“…This is a common feature of citrus fruits due to their thick exocarp which contributes to 20-50% of total weight. The pomelo by-products such as peels, seeds, and leaves that accrue during processing of the fruit have been drawing the attention of researchers due to their potential beneficial aspects in pharmaceutical, food, or cosmetic industries [2][3][4]. The extraction of essential oils is considered the main solution to utilize this by-product.…”
