Embodiment 1

[0017] Step 1. The fresh orange peel is vacuum dried at 45°C for 1.5 hours, and then crushed to 60 mesh to make orange peel powder;

[0018] Step 2: Spray a small amount of ethanol on the orange peel powder, then place it in the extraction kettle, put carbon dioxide in, and extract for 3 hours at a pressure of 20MPa and a temperature of 40°C, and the flow rate of the carbon dioxide fluid is 20L / h;

[0019] Step 3. The supercritical carbon dioxide fluid with the extract dissolved in it undergoes primary separation and secondary separation, the primary separation pressure is 6MPa, the temperature is 60°C, the secondary separation pressure is 5MPa, and the temperature is 55°C to obtain orange peel essential oil;

[0020] Step 4: Filter the orange peel extract with qualitative filter paper, then filter with organic microporous membrane, then heat it in a water bath at 40°C for 30 minutes, and separate it through a centrifuge at 10,000 r / min to obtain orange peel essential oil.

Embodiment 2

[0022] Step 1. The fresh orange peel is vacuum dried at 55°C for 1 hour, and then crushed to 100 mesh to make orange peel powder;

[0023] Step 2: Spray a small amount of ethanol on the orange peel powder, then place it in the extraction kettle, put carbon dioxide in, and extract at a pressure of 40MPa and a temperature of 60°C for 1 hour, and the flow rate of the carbon dioxide fluid is 30L / h;

[0024] Step 3. The supercritical carbon dioxide fluid in which the extract is dissolved undergoes primary separation and secondary separation, the primary separation pressure is 10MPa, the temperature is 50°C, the secondary separation pressure is 7MPa, and the temperature is 30°C, to obtain orange peel essential oil;

[0025] Step 4. Filter the orange peel extract with qualitative filter paper, then filter with organic microporous membrane, then heat it in a water bath at 50°C for 30 minutes, and separate it through a centrifuge at 5000 r / min to obtain orange peel essential oil.

Embodiment 3

[0027] Step 1. The fresh orange peel is vacuum dried at 50°C for 1.2 hours, and then crushed to 80 mesh to make orange peel powder;

[0028] Step 2: Spray a small amount of ethanol on the orange peel powder, then place it in the extraction kettle, put carbon dioxide in, and extract for 2h at a pressure of 30MPa and a temperature of 40℃-60℃, and the flow rate of the carbon dioxide fluid is 25L / h;

[0029] Step 3. The supercritical carbon dioxide fluid in which the extract is dissolved undergoes primary separation and secondary separation, the primary separation pressure is 8MPa, the temperature is 55°C, the secondary separation pressure is 6MPa, and the temperature is 40°C to obtain orange peel essential oil;

[0030] Step 4. Filter the orange peel extract with qualitative filter paper, then filter with organic microporous membrane, and then heat it in a water bath at 45°C for 30 minutes, and separate it through a centrifuge at 8000r / min to obtain orange peel essential oil.

Abstract

The invention relates to the field of essential oil extraction, and particularly relates to a method for extracting tangerine peel essential oil. The method comprises the following steps: drying fresh tangerine peels in vacuum, and grinding to obtain tangerine peel powder; spraying a small amount of ethanol on the tangerine peel powder, and putting the tangerine peel powder having ethanol in an extraction kettle, introducing carbon dioxide, and extracting; carrying out primary separation and secondary separation on supercritical carbon dioxide in which extract is dissolved to obtain tangerine peel essential oil; filtering the tangerine peel extract with qualitative filter paper and an organic microfiltration membrane sequentially, then heating in a water bath, and separating by virtue of a centrifugal machine to obtain the tangerine peel essential oil. The method is simple and reasonable, and the product has high extraction rate and high purity, usage of massive organic solvent is avoided, the tangerine peel essential oil is non-toxic and purely natural, and has high quality, rich fragrance, comprehensive effective ingredients and high edible and medicinal values.

Description

Technical field [0001] The invention relates to the field of essential oil extraction, in particular to a method for extracting orange peel essential oil. Background technique [0002] Orange peel, as the name suggests, refers to the peel peeled from an orange. Orange peel is rich in vitamin C, which has medicinal, beautifying and cooking delicacies. The orange peel essential oil obtained by the existing extraction method is not comprehensive, and some effective ingredients of the orange peel cannot be extracted, which makes the taste of the orange peel lack and reduces the edible and medicinal value. Summary of the invention [0003] The purpose of the present invention is to provide a method for extracting orange peel essential oil to solve the defects in the prior art. [0004] In order to achieve the above objectives, the following technical solutions are adopted. A method for extracting essential oil from orange peel includes the following steps: [0005] Step 1. The fresh or...
