Embodiment 1

[0020] see figure 1 , select the column height of the pulse extraction column to be 1m-3m, and the column height-to-diameter ratio is 10-50. In this embodiment, the column diameter is 50mm and the column height is 1100mm. The column body is made of glass with a thickness of 2.5mm, and the column is filled with stainless steel CY700 type filler. The binary solvent selects ethanol and water, 70% ethanol-water solution, totally 2500g, tangerine oil 500g. The extraction is carried out under normal pressure at 1 to 1.2 atmospheres, and at room temperature between 15°C and 25°C. The pulse generator is composed of an air compressor, compressed air, nitrogen or carbon dioxide cylinder, and a solenoid valve. This embodiment uses a pulse generator composed of a compressed air cylinder and a solenoid valve. The vibration frequency is controlled by the solenoid valve, and the pulse amplitude is controlled by the gas pressure. , The pulse amplitude is 12.5 ~ 25mm. The debugging process ...

Embodiment 2

[0031] The same as in Example 1, the difference is that 500 g of sweet orange oil is placed in the pulse extraction column of Example 1, methanol and water are selected as the binary solvent, and 65% methanol-water solution is made, and about 10 g of citric acid is obtained through extraction and salting out. Sesquiterpene-free sweet orange oil. Wherein the total aldehyde content (calculated as decanal) is 30.12%.

[0032] Methanol was not detected by chemical method, and the aroma of sesquiterpene-free sweet orange oil was found to have a very strong sweet orange characteristic aroma, and the fragrance retention time was 4 times longer than that of sweet orange essential oil, up to 20 hours. The aroma is transparent, realistic and fruity.

Embodiment 3

[0034] Same as Example 1, the difference is that 500g of lime oil is placed in the pulse extraction column of Example 1, and 75% ethanol-water solution is selected for binary statistics. In order to ensure complete separation of the two phases, the density of ethanol-water solution is controlled to be greater than that of the terpene phase. If 0.03g / cm3 is insufficient, add some sodium chloride to the solution to increase the density. Finally, about 35g of sesquiterpene-free white lemon oil is obtained, which has a strong white lemon aroma and cola-like aroma, and the fragrance lasts for as long as 48 hours.

Abstract

The invention discloses a production method of sesquiterpene-free orange oil. The sesquiterpene-free orange oil is finally obtained by performing pulse reverse current liquid-liquid extraction on orange oil and salting delamination. The production method comprises the following steps of: supplying pulses to an extraction column through a pulse generator to fully mix the orange oil with a binary solvent; realizing reverse current liquid-liquid extraction in a pulse state; removing terpene compounds from the orange oil to obtain a terpene phase and a solvent phase, wherein the solvent phase only comprises an aldehyde, a ketone, an alcohol, an ester and a solvent, and the terpene phase only comprises terpene compounds; and adding saturated saline solution, performing salting delamination to separate the aldehyde, ketone, alcohol and ester out of the solvent phase, and centrifugally skimming to obtain the sesquiterpene-free orange oil. According to the method, the problem of the need of heating in a production process is solved, extraction efficiency is increased and a separation effect is enhanced by performing pulse extraction, the aldehyde, ketone, alcohol and ester are completely separated from the terpene compounds, and the obtained sesquiterpene-free orange oil has strong fragrance, lasting fragrance and rich characteristic feel.

Description

technical field [0001] The present invention relates to a kind of production method of natural fragrance, especially a kind of production method of sesquiterpene-free citrus oil. Background technique [0002] Citrus oil is obtained from the peel by cold grinding and pressing. It is the most commonly used fruity oil and is widely used in the field of essence. The main components of citrus oil are terpenes and oxygen-containing compounds. Terpenes are composed of carbon and hydrogen elements. According to the number of carbon atoms, they are generally divided into monoterpenes, sesquiterpenes, diterpenes, and triterpenes. , wherein monoterpenes include D-limonene, myrcene, α-pinene, etc.; sesquiterpenes are mainly represented by caryophyllene, bergamotene and valenciaene. The content of terpenes in citrus oil is as high as 95%. [0003] Table 1 Contents of various terpenes in sweet orange oil [0004] [0005] It can be seen from the above table that terpenes account for...
