Abstract

The invention discloses a preparation method of high-purity citrus aurantium flower essential oil and flavor addition essence used for cigarettes and blended with the high-purity citrus aurantium flower essential oil. The preparation method of the high-purity citrus aurantium flower essential oil takes fresh citrus aurantium flowers as raw material and comprises the following steps: carrying out atomizing, pre-freezing, vacuum sublimation and drying and crushing treatment on the raw materials in sequence, and filling the crushed citrus aurantium flower raw material and fluid at a supercritical state into an extraction kettle; extracting to obtain crude oil extracted from the citrus aurantium flower supercritical fluid; and carrying out secondary molecular distillation on the citrus aurantium flower crude oil and purifying and separating to obtain the high-purity citrus aurantium flower essential oil. Then the high-purity citrus aurantium flower essential oil is blended with California lemon oil, Brazilian sweet orange oil, caraway oil and alcohol to prepare the flavor addition essence used for the cigarettes. According to the preparation method disclosed by the invention, the citrus aurantium flower oil can be rapidly, efficiently and sufficiently extracted and separated; the operation is simple and convenient, the separation speed is rapid and the production efficiency is greatly improved; and the prepared flavor addition essence used for the cigarettes and blended with the citrus aurantium flower essential oil has soft, fine and smooth smoke and the effect of increasing the sweet taste of the smoke is enhanced.
