Embodiment 1

[0016] A method for extracting essential oil from orange peel, comprising the following steps:

[0017] 1 Select fresh orange peels without mildew, and put them in a cool, ventilated and dry place for later use;

[0018] 2 Take 100 g of orange peels from step 1) and soak them in 1 L of calcium carbonate saturated aqueous solution for 24 hours, remove and rinse;

[0019] 3. Cut the orange peel into 5mm square pieces, soak in ethanol with a volume fraction of 70% for 30 minutes, and remove the ethanol by rotary evaporation under reduced pressure;

[0020] 4 Irradiate under ultraviolet light for 15 minutes, send it into a screw press, add 100ml of pH regulator when pressing, the components of pH regulator are: 0.2mol / L NaCl and 0.1mol / L NaHCO 3 ;

[0021] 5. Get the filtrate after filtering the squeezed matter, and take out the filter residue for the subsequent production process of other products; add a mass volume fraction of 5% sodium sulfate solution at a volume ratio of 10...

Embodiment 2

[0023] A method for extracting essential oil from orange peel, comprising the following steps:

[0024] 1 Select fresh orange peels without mildew, and put them in a cool, ventilated and dry place for later use;

[0025] 2 Take 100 g of orange peels from step 1) and soak them in 1 L of calcium carbonate saturated aqueous solution for 24 hours, remove and rinse;

[0026] 3 Cut the orange peel into 5mm square pieces, soak in 70% ethanol for 40 minutes, and remove the ethanol by rotary evaporation under reduced pressure;

[0027] 4 Irradiate under ultraviolet light for 30 minutes, send it into the screw press, add 100ml of pH regulator when pressing, the components of the pH regulator are: 0.2mol / L NaCl and 0.1mol / L NaHCO 3 ;

[0028] 5. Get the filtrate after filtering the squeezed matter, and take out the filter residue for the subsequent production process of other products; add a mass volume fraction of 5% sodium sulfate solution at a volume ratio of 10:1 according to the f...

Embodiment 3

[0030] 1, by the essential oil component analysis that embodiment 1 extracts:

[0031] The components of essential oils were analyzed by GC-MS technology: D-limonene 81.17%, terpinene 6.27%, myrcene 2.96%, linalool 2.468%, 2-thujene 1.28%, terpinolene 1.046%, and other minor components.

[0032] The beneficial effect that extraction process of the present invention brings:

[0033] 2. Appropriate amount of ethanol treatment:

[0034] Using an appropriate amount of ethanol treatment greatly releases the dissolution rate of the essential oil, and the ethanol treatment step avoids being mixed into the essential oil before the pressing step; the influence of the ethanol treatment step on the dissolution rate of the essential oil: according to the operation method of Example 1 , repeating ten batches, removing the ethanol treatment step and repeating ten batches; we found that the embodiment of the ethanol treatment step was not adopted, and the productive rate was 7.18 ± 0.23g / k...

Abstract

The invention relates to a technology for extracting essential oil from a plant, and particularly relates to a preparation technology for extracting essential oil from an orange peel. The technology improves and optimizes the conventional extraction method in the prior art, boldly adopts the steps such as ethanol treatment, ultraviolet irradiation, salt ion aging and the like, and effectively combines and optimizes reaction parameters, thereby greatly improving the production efficiency of essential oil and having wide application prospects.

Description

technical field [0001] The invention relates to a process technology for extracting essential oil from plants, in particular to a preparation process technology for extracting essential oil from orange peel. Background technique [0002] Essential oil exists in the small secretory glands of orange or citrus peel and is an important by-product in orange or citrus processing. Widely used in the production of flavoring agents, beverages, food, cosmetics, alcohol and tobacco products, soap, pharmaceutical products and pesticides. In recent years, it has been reported in the literature that essential oils have the effect of calming the central nervous system of the human body and reducing stress, and can eliminate fatigue. The trace amount of coumarin contained in it has obvious anticancer effect. Its anticancer mechanism is to decompose the toxic functional groups of carcinogens and inhibit the metabolic activation of cancerous cells. [0003] The prior art discloses a variety...
