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.
