“…This technique constitutes the preferred large‐scale commercial extraction system by the production of essential oils from aromatic plants such as lavender (Gavahian & Chu, 2018). About 90% of essential oils are produced using this method (Radwan et al., 2020). It is a modified distillation system for the recovery of temperature‐sensitive materials.…”

“…The heating and evaporation of the water generate an interaction between the steam and the plant material, carrying out solubilization of the oils (Zhang et al., 2020). Some researchers have tested the use of electric and solar heating systems, finding that the efficiency and performance of the essential oils obtained are influenced by the heat flow and the batch size of the plant material (Kant & Kumar, 2021; Radwan et al., 2020). It should be noted that this type of extraction involves the loss of some chemical components due to the high temperatures applied (Valderrama & Ruiz, 2018).…”

Essential oils are volatile substances of an oily nature present in all plants. They are industrially used as high-value substances for their biological properties in the elaboration of various products in multiple such as pharmaceuticals, food, cosmetics, etc.Today it is known that essential oils have a composite composition and are mainly made up of hydrocarbons and oxygenated compounds, being the trace components contained in these substances, those responsible for providing the odor they possess. Commonly, essential oils are extracted through so-called conventional, where high temperatures and solvents dominate the processes. However, nowadays, multiple emerging techniques have been used to carry out its extraction to achieve better yields, preserve the integrity of the components and reduce the environmental impact that conventional extraction systems imply. This paper addresses a review of conventional systems and emerging technologies that are currently used for the extraction of essential oils.

“…This system used solar cells to generate electricity to operate a vacuum pump along with a box filled with ice as the cooling section. Radwan, Morad, Ali, and Wasfy (2020) used a concentrated solar essential oil extractor to extract lavender oil. This system required 2-4 h of processing time and operated at 100 C. Kumoro et al (2021) utilized ultrasound as a pre-treatment to extract essential oil from Citronella Grass (Cymbopogon nardus) leaves using solar energy hydrodistillation to increase oil yield and decrease extraction time.…”

Conventional essential oil extraction systems cannot meet the green extraction concepts and sustainable development goals (SDGs). Therefore, there is a need to develop alternative systems based on clean energy. The present study aims to investigate the possibility of essential oil extraction using solar energy without utilizing synthetic solvents. Hence, an eco-friendly solar energy-based extraction system (SEE) was developed to extract essential oils from cloves and cinnamon barks, orange and lemon peels, eucalyptus leaves, and cardamom seeds. Essential oils were assessed in terms of yield, physical properties, and chemical composition using gas chromatography-mass spectrometry assay. Also, the process sustainability was analyzed by the green extraction evaluation approach, and results were compared with those of traditional hydro-distillation (THD). Replacing THD with SEE increased the extraction time by 0.65, 0.80, 0.41, 0.61, 0.39, and 0.45 h for processing clove, cinnamon, orange, lemon, eucalyptus, and cardamom, respectively. The optimum solar radiation for extraction was about 1000 W/m 2 . Also, oxygen compounds (96.45, 79.640, 42.98, and 83.76%) comprised the main proportion in the clove, cinnamon, eucalyptus, and cardamom essential oils, while orange and lemon essential oils had a high presence of terpenes. Furthermore, essential oils obtained by SEE had a similar yield and alcohol solubility to THD. According to green extraction process analysis, solar energy-based extraction was 23-34% greener than THD, depending on the type of plant material. Practical ApplicationsThe innovative solar-based extraction system designed and developed in this research can be used at farms and small factories to obtain essential oils using the zero-energy concept. From the energy consumption viewpoint, this technology can be regarded as "free process" which can reduce production costs. Also, the unique design of the heating section of this new system prevents overheating of the sample, making this new solar-based system suitable for the extraction of thermolabile compounds from plant materials. In this sense, obtaining a high-quality essential oil

“…As gas prices are higher especially in Pakistan, the conventional distillation system is becoming expensive in terms of cost of production. On the contrary, a solar-based distillation system turns out to be cost-effective, energy optimal, and coherent [24][25][26]. This study aimed to develop an on-farm solar distillation system to process the fresh supply of different medicinal and aromatic plants with solar energy.…”

Most of the industrial process requires a temperature level below 250?C which is easily achievable using solar energy. Pakistan is fortunate enough to have long sunlight hours and high intensity of solar insolation. The mean total irradiation falling on a horizontal plane is about 200-250 Watt per m2 per day. This precious source of natural energy has tremendous potential in the agro-based industry like the distillation of medicinal plants. The main objective of this study was to conduct a Quantitative and Qualitative analyses of solar distilled oil of the medicinal plant. Solar distillation systems had been installed at Agricultural Engineering Workshop, Faculty of Agricultural Engineering and Technology and Rosa Lab, Institute of Horticultural Sciences, University of Agriculture Faisalabad. This distillation system was designed according to the latitude of Faisalabad. This system comprised of primary reflector, secondary reflector, condenser, and Florentine flask. In this study Eucalyptus Camaldulensis and Eucalyptus Citriodora, essential oils were distilled by solar distillation system and by a conventional distillation system for comparing the results. GC-MS analysis of Eucalyptus Camaldulensis and Eucalyptus Citriodora essential oils were carried out at National Institute of Biotechnology and Genetic Engineering (NIBGE), Faisalabad. The results of quantitative and qualitative analyses of essential oils showed that the quantity and the quality of essential oils of same species of Eucalyptus, distilled by Solar distillation system and conventional controlled distillation system were same. So, it was concluded that the quality and quantity of essential oils of same species don?t differ significantly either distilled by solar distillation system or by conventional controlled distillation system.
