In the domain of essential oil production, the process of steam distillation stands out as a natural and effective method for extracting pure oils with preserved therapeutic benefits. Steam distillation involves passing steam through plant materials to extract oils gently without harsh chemicals.
Steam distillation is a method of extracting essential oils from plants using hot steam to separate the oil from the plant material. Steam distillation is preferred for isolating essential oils because it is a gentle process that preserves the natural properties and aroma of the oils.
The concentrated natural plant components containing volatile fragrant com-pounds are essential oils (EOs), otherwise called volatile oils. Most EOs are inferred by steam distillation and have remarkable properties, which bring about different opportunities for application, likewise in the present medical context [5].
The most-used method for essential oil extraction is steam distillation due to its simplicity and low investment requirements. Due to the importance of this extractive method, technological updates represent an immense opportunity for improving this component of essential oil production.
There are various techniques for extracting essential oils, such as steam distillation (SD), hydrodistillation (HD), subcritical water extraction (SWE), supercritical CO 2 extraction (SCOE), and superheated steam distillation (SHSD). HD and SD are two conventional methods that employ heat and steam to extract essential oils from plant biomass.
Steam distillation is the most widely used method for extracting essential oils. This classic technique involves using hot steam to release the aromatic compounds from the plant material. Here’s a step-by-step breakdown of the steam distillation process:
