Problems solved by technology

[0003] At present, there are few researches on the method of extracting tea seed oil from tea tree seeds, and the traditional oil extraction methods are generally pressing method and organic solvent extraction method. These methods not only have long extraction process, high energy consumption and low yield , seriously pollute the environment, and the quality of the extracted product is poor and the purity is low; the product obtained by the organic solvent extraction method also has odor and solvent residues harmful to the human body

Embodiment 1

[0012] refer to figure 1 : (1) Dry 2Kg tea tree seeds, crush them to 20 mesh and put them into the barrel of 5L extraction tank 8; (2) Set the temperature of cold box 5 to 0°C, and set the temperature of extraction tank 8 to 35 ℃, the temperature of the separation tank I10 is set to 55 °C, the temperature of the separation tank II12 is set to 55 °C, and the CO 2 Cylinder 2, CO 2 Come out of the steel cylinder 2, enter the cold box 5 for liquefaction through the gas purifier I3, and then start the high-pressure pump 6 to remove the CO 2 After purifier Ⅱ4 and preheater Ⅰ7, it enters the extraction cylinder 8, boosts the pressure to 30MPa, makes it a supercritical fluid for extraction, and enters the preheater Ⅱ9 to preheat before entering the separation system. The complete separation of similar substances can reduce the follow-up processing work, adopt secondary separation, adjust the pressure of the separation tank I10 to 10MPa, and keep the pressure of the separation tank I...

Embodiment 2

[0015] Dry 2Kg tea tree seeds, crush them to 30 mesh, control the pressure of the extraction tank to 35MPa, set the temperature to 40°C, adjust the pressure of the separation kettle I to 9MPa, set the temperature to 55°C, and set the temperature of the separation kettle II to 55 ℃, other with embodiment 1, extract 3 hours, collect grease 308g, extraction rate is 15.4%.

[0016] The content of unsaturated fatty acid in the sample was determined by GC-MS method to be 82.7%; the content of tea polyphenols in the sample was determined by iron tartrate chromogenic method to be 8.3%; the content of vitamin E in the sample was determined to be 1.34 mg / g by UV spectrophotometry.

Embodiment 3

[0018] Dry 2Kg of tea tree seeds, crush them to 40 meshes, control the pressure of the extraction cylinder to 25MPa, set the temperature to 55°C, adjust the pressure of the separation kettle I to 8MPa, set the temperature to 60°C, and set the temperature of the separation kettle II to 60°C ℃, other is the same as embodiment 1, extracts 2.5 hours, collects fat 254g, and extraction rate is 12.7%. The content of unsaturated fatty acid in the sample was determined by GC-MS method to be 83.4%; the content of tea polyphenols in the sample was determined by iron tartrate chromogenic method to be 7.9%; the content of vitamin E in the sample was determined to be 1.49 mg / g by UV spectrophotometry.

Abstract

The invention relates to a method for extracting tea seed oil from tea tree seeds, which comprises the following steps: (1) crushing: drying the tea tree seeds, crushing to 16-40 meshes and putting in an extraction cylinder; (2) extracting: setting the temperature of an ice chest to be -3 DEG C-3 DEG C, pumping liquefied CO2 into the extraction cylinder by using a high-pressure pump through a purifier II and a preheater I, increasing pressure to 20MPa-40MPa and then extracting for 2h-4h under controlling the temperature of the extraction cylinder to be 35-60 DEG C; (3) separating: CO2 fluid containing grease enters a separating kettle from the extraction cylinder for separation, wherein the pressure of the separating kettle is 6MPa-12MPa, and the temperature thereof is 35-60 DEG C, the pressure of a separating kettle II is balanced with the posterior pressure, and the temperature is 35-55 DEG C. The invention has high extraction efficiency, low energy consumption, no environmental pollution, high product quality, high purity and no solvent residuals.

Description

technical field [0001] The invention relates to a method for extracting tea seed oil from tea tree seeds, in particular to a method using supercritical CO 2 Extraction technology is a method of extracting tea seed oil from tea tree seeds. Background technique [0002] Tea tree (Camellia sinensis) belongs to the genus Camellia of the family Theaceae, and is a perennial evergreen woody plant. The leaves of the tea tree are oval, with sawtooth on the edge, and five petals of white flowers are opened between the leaves. The fruit is oblate and triangular in shape, and the seeds are exposed after the fruit is opened. In spring and autumn, the young leaves of the tea tree can be picked to make tea, and the seeds can be used to extract oil. At present, the utilization value of the tea tree is mainly in the tea leaves, and the utilization value of the seeds has not been developed. [0003] At present, there are few researches on the method of extracting tea seed oil from tea tree ...
