Problems solved by technology

However, due to this method, the oil cell is immersed in alkaline lime water, saponification reaction occurs, and orange complex is prone to browning reaction under alkaline conditions, so that the aroma of the oil is significantly reduced, and the color is significantly worse.
It is also produced by steam distillation and organic solvent extraction of tangerine complex, but the steam distillation method consumes a lot of energy, and high-temperature distillation is easy to cause the decomposition, hydrolysis, oxidation, and isomerization of aroma components, which reduces the oil quality. Oil with poor aroma and dark color
The organic solvent extraction method has solvent residues, which is not safe

Embodiment 1

[0013] Fresh tangerines, washed and drained. Squeeze with a screw press, and each batch of tangerine raw material is 100 kg. When squeezing, spray 20 kg of water from the nozzle of the squeezer to squeeze out 7 kg. The resulting juice is filtered with a 100-mesh screen. After filtering, add 5% of the filtrate Table salt, stand still for 24 hours, separate the citrus oil of the upper layer, place the citrus oil in a cold room at 5°C for 7 days, separate the upper layer of tangerine essential oil, and obtain 0.96 kg of essential oil. The obtained essential oil was purified by high-vacuum distillation, and the vacuum degree was controlled to 40 Pa. At 90° C., distilled until no distillate was distilled to obtain 0.72 kg of colorless and transparent essential oil.

Embodiment 2

[0015] Fresh tangerines, washed and drained. Squeeze with a screw press, each batch of tangerine raw materials is 100 kg, spray 18 kg of water from the nozzle of the press during pressing, and squeeze out 28 kg of juice, filter the obtained juice with an 80-mesh screen, and add 6% of the filtrate after filtration salt, stand still for 20 hours, separate the citrus oil of the upper layer, place the citrus oil in a 7°C refrigerator for 9 days, separate the upper layer of tangerine essential oil, and obtain 0.87 kg of essential oil. The obtained essential oil was purified by high-vacuum distillation, and the vacuum degree was controlled to be 50 Pa. At 90° C., distilled until no distillate was distilled to obtain 0.61 kg of colorless and transparent essential oil.

Embodiment 3

[0017] Fresh tangerines, washed and drained. Squeeze with a screw press, each batch of tangerine raw materials is 100 kg, spray 22 kg of water from the nozzle of the press during pressing, and squeeze out 26 kg of juice, filter the obtained juice with a 120-mesh screen, add 5% of the filtrate after filtering salt, stand still for 28 hours, separate the citrus oil of the upper layer, and place the citrus oil in a refrigerator at 6°C for 8 days, separate the upper layer of tangerine essential oil to obtain 0.91 kg of essential oil. The obtained essential oil was purified by high-vacuum distillation, and the vacuum degree was controlled to be 40 Pa. At 80° C., distilled until no distillate was distilled to obtain 0.64 kg of colorless and transparent essential oil.

Abstract

The invention discloses a tangerine pith essential oil preparation method. The method includes the steps of firstly, adding tangerine pith and water into a screw extrusion press to be extruded according to the mass ratio of 10 to 1.8-2.2, and filtering liquid obtained through extrusion through a sieve of 80-120 meshes to obtain filtrate; secondly, adding salt accounting for 5-7% of the mass of the filtrate to the filtrate in the first step to be evenly mixed, standing for 20-28 h, pouring out tangerine pith oil on the upper layer to be placed in a refrigerating chamber at a temperature of 5 DEG C to 7 DEG C for 7-9 days, and then separating out the upper layer to obtain a tangerine pith essential oil crude product; thirdly, conducting decompression distilling and purifying on the tangerine pith essential oil crude product, collecting distillate till no distillate is evaporated, and obtaining tangerine pith essential oil, wherein the tangerine pith essential oil is obtained after decompression distilling is conducted at a temperature of 70-90 DEG C and at a vacuum degree of 40-60 Pa. The tangerine pith essential oil has effects on dredging collaterals, regulating vital energy, reducing phlegm and treating meridian qi depression, chronic coughs and chest pain, blood-stained sputum and alcoholism thirst and is quite safe to human bodies.

Description

technical field [0001] The present invention relates to a kind of essential oil, specifically, relate to a kind of preparation method of orange essence essential oil. Background technique [0002] At present, Juluo essential oil is a pure natural product with high safety. Traditional Chinese medicine believes that Juluo has the functions of dredging collaterals, resolving phlegm, smoothing qi and activating blood circulation. The chest and hypochondriac pain and discomfort caused by it have adjuvant therapeutic effect. Its production method is obtained by directly pressing the tangerine pulp as the raw material. In order to improve the yield, lime water is often used to treat the tangerine complex, so that the oil yield of the tangerine complex can be increased during pressing, which is called the lime water impregnation pressing method. However, because the oil cell is immersed in alkaline lime water in this method, a saponification reaction occurs, and at the same time, ...
