Plant essential oils, also known as volatile oils or essential oils, are oily liquids with an aromatic scent, derived from flowers, bracts, leaves, branches, roots, bark, fruits, seeds and resins of herbs, extracted by distillation, pressing, solvent extraction, etc. These highly volatile substances, which can be absorbed into the body by the mucous membrane tissue of the nasal cavity, send messages directly to the brain and regulate emotions and physiological functions of the body through the limbic system of the brain. BOC Sciences provides essential oil extraction services for plants.
Water steam distillation is one of the main methods for producing aromatic oils due to the simplicity of the equipment and the ease of operation. The main points to consider when extracting are the following.
Based on the professional laboratory instruments and equipment owned by BOC Sciences, we can provide our clients with natural product extraction services. We have a full range of integrated services for plant essential oil extraction, including raw material pretreatment, essential oil extraction, refining, separation and purification services, you can find the corresponding services.
Harvesting of raw materials - Although various raw materials are different and have different requirements, they should be stored for a period of time after harvesting and then distilled to help improve the content of essential oils.
Storage and storage of raw materials - if you can not process in time, can be stored in a dry, cool, well-ventilated warehouse, if necessary, you can install air conditioning equipment. But we should pay attention to the airflow should not be too strong, otherwise it will cause the volatilization of essential oil. If the temperature of the warehouse is too high, it will make the essential oil oxidation, etc.
Crushing of raw materials - the purpose of crushing is to expose more oil cells for fast distillation.
The chemical composition of essential oils is very complex, mainly terpenes and their derivatives, but also contains aromatic compounds, but their common point is that they are volatile and can be distilled out with water vapor. Depending on the source of raw materials, parts of the essential oil extraction methods also vary, commonly used methods are water vapor distillation, leaching method, pressing method and adsorption method four categories.
