Problems solved by technology

This method has obvious improvement compared with the traditional camellia oil production method, and adopts oil phase, water phase, slag phase method to carry out extraction respectively, but the recovery rate of tea saponin is only 85%, has not fully recovered; It is very time-consuming and energy-intensive to crush the camellia seed kernels containing viscous oil to 100 mesh, 160 mesh, and 200 mesh.

Embodiment 1

[0023] A supercritical CO 2 Method for extracting and purifying Camellia oleifera seed oil:

[0024] Step 1: Shelling. Camellia oleifera fruit peeling, using a camellia oleifera fruit peeling machine, peeling off the husk to obtain camellia oleifera seed kernels, the water content of the camellia oleifera seed kernels is 15%;

[0025] Step 2: Crush. Get 100kg camellia oleifera seed kernel and grind, the crushing fineness of camellia oleifera seed kernel powder is 20-50 order;

[0026] Step 3: alcoholysis. Add 1.0-1.5 parts by weight of alcohol solution to 100 kg of Camellia oleifera seed and nut powder, so that the volume percent concentration of the alcohol is 10-15%, the temperature of the mixed solution is 60-70° C., pH 6-8, and the time is 2-3 hours; Then heated to 80-90 ° C, reflux extraction for 2 hours, and then filtered; recovery of ethanol, alcoholysis. Ethanol is 75% ethanol.

[0027] Step 4: Hydrolysis. Mixing 100 kg of alcohol extract of camellia oleifera se...

Embodiment 2

[0033] Get 200kg of camellia oleifera seed kernels and pulverize, and the pulverization fineness of camellia oleifera seed kernel powder is 20-50 mesh. The water content of Camellia oleifera seed kernel is 15%.

[0034] The preparation method is the same as in Example 1. 30.5kg of tea saponin dry powder was obtained; 61.2kg of high-quality camellia oleifera oil was obtained.

Embodiment 3

[0036] Get 300kg of Camellia oleifera seed kernels and grind, and the crushing fineness of Camellia oleifera seed kernel powder is 20-50 mesh. The water content of Camellia oleifera seed kernel is 15%.

[0037] The preparation method is the same as in Example 1. 46.5kg of tea saponin dry powder was obtained; 91.6kg of high-quality camellia oleifera oil was obtained.

[0038] An example of the preparation method for extracting camellia oleifera seed oil and active substances from camellia oleifera seeds. The main component content analysis is shown in the following table:

[0039]

[0040] 1. The determination standard of Camellia oleifera seed oil is determined by GB11765-2003 Camellia oleifera seed oil standard

[0041] 2. The detection of tea saponin adopts the import and export industry standard SN / T1852-2006 Determination of saponin content in tea saponin for export

Abstract

The invention discloses a method for supercritical CO2 extraction and purification of camellia seed oil; camellia seeds are subjected to deshelling, crushing, alcoholysis, hydrolysis, enzymolysis, filtration, supercritical CO2 extraction, separation and purification to obtain the purified camellia seed oil, the extraction rate of the camellia seed oil is more than or equal to 98%, and the extraction rate of tea saponin is more than or equal to 93%. The prepared camellia seed oil is rich in organic acids, amino acids, vitamin E, polysaccharides and other natural active substances, is good in quality and excellent in stability of tea saponin, and has the extraction rate substantially increased compared with a traditional camellia seed oil extraction method; the quality of the grease is higher; and the preparation method is advanced in technology, efficient, environmentally friendly and hygienic, and has remarkable economic benefits.

Description

technical field [0001] The invention belongs to the technical field of edible oil production, processing and extraction, and specifically relates to a supercritical CO 2 A method for extracting and purifying camellia oleifera seed oil. Background technique [0002] Camellia oleifera (camellia oleifera) is another name: tea seed tree, tea oil tree. Camellia oleifera is known as the world's four largest woody edible oil plants together with oil palm, olive and coconut. It grows in the high mountains and hills in the subtropical regions of southern my country, and is a unique pure natural high-grade edible oil crop in China. Mainly concentrated in Fujian, Zhejiang, Jiangxi, Henan, Hunan, Guangxi and other provinces, the national annual output is 1 million tons. The tea saponin content of camellia oleifera seed is about 8.0-15.0%. The Camellia oleifera seed oil content is about 18-30%. Camellia oleifera seed oil has an unsaturated fatty acid content as high as 90%, which is...
