The potential for essential oil production in Vietnam is huge, but sadly, after producing crude oil, we often have to sell cheaply and import refined essential oil at a high price because of lack of technology!
Dr. Trinh Van Dung, Department of Chemical Technology, Ho Chi Minh City University of Technology commented.
Due to lack of refining technology, after selling crude oil, Vietnam often has to import refined oil several times higher to use in cosmetics, food, pharmaceuticals ... The method is used quite popular. Variable to purify essential oil is distilled. To achieve this method, refiners must go through a lot of complicated steps.
Essential oils extracted from plants of natural origin are a mixture of high-value substances in the fields of medicine, pharmaceuticals, food, cosmetics, flavoring and export.
The essential oil is highly valuable when the mixture is separated from each other. For example, rosin crude oil has a price of 300 USD / liter, when processed into refined essential oil, the price increases to 700 USD / liter.
Essential oils are found in all parts of plants: flowers, leaves, branches, stems, shells, roots, tubers ... Currently in Vietnam there are about 20 types of plants for essential oils that have been grown and exploited. The content of essential oils in plants depends on factors such as: seed, soil, cultivation conditions, harvesting and processing methods.
