Embodiment 1

[0024] Dehull the gardenia seeds, dry them in a microwave at a power of 1.2kW, the thickness of the gardenia seeds is 5-10cm, dry for 1.0h, crush the dried gardenia seeds, put them into the extraction kettle, inject propane for extraction The kettle is mixed with gardenia seed raw materials, the mass volume ratio of propane to raw materials is 1:5~1:8 (g:mL), and 2~3 times, each time for 0.5-1.0h, after the extraction is completed, the propane carrying gardenia seed oil is transported to the separation kettle, and then evaporated under reduced pressure to fully vaporize the propane. During the evaporation process, the temperature is controlled at 30-50°C. After the recovery of propane is complete, the extracted crude gardenia seed oil is discharged from the bottom of the separation tank, the yield is 15-20%, the color is orange, and the fatty acid composition is analyzed by GC-MS. The crude gardenia seed oil is used as a raw material, diatomaceous earth and activated carbon ar...

Embodiment 2

[0026] The gardenia seeds are shelled, and the power of microwave drying is 0.1-1.5kW, the thickness of the gardenia seeds is 5-10cm, and the drying time is 0.5-2.0h. The dried gardenia seeds are crushed and put into the extraction kettle. Inject butane into the extraction kettle and mix it with gardenia seed raw materials. The mass volume ratio of butane to raw materials is 1:5~1:8 (g:mL). Under the same conditions, extract 2 to 3 times, each time for 0.5 to 1.0h. After the extraction is completed, the butane carrying the gardenia seed oil is transported to the separation tank, and then evaporated under reduced pressure to fully vaporize the butane. The evaporation process Control the temperature at 30-50°C. After the recovery of butane is complete, release the extracted crude gardenia seed oil from the bottom of the separation tank. The yield is 15-20%, the color is orange, and the fatty acid composition is determined by GC-MS analyze. The crude gardenia seed oil is used as...

Embodiment 3

[0028] The gardenia seeds are shelled, and the power of microwave drying is 0.1-1.5kW, the thickness of the gardenia seeds is 5-10cm, and the drying time is 0.5-2.0h. The dried gardenia seeds are crushed and put into the extraction kettle. Inject dimethyl ether into the extraction kettle and mix it with gardenia seed raw materials. The mass volume ratio of dimethyl ether to raw materials is 1:5-1:8 (g:mL). The extraction temperature is 30-50°C and the extraction pressure is 0.6-0.8 Under the condition of Mpa, extract 2 to 3 times, each time for 0.5 to 1.0h. After the extraction, the dimethyl ether carrying the gardenia seed oil is transported to the separation kettle, and then evaporated under reduced pressure to fully gas the dimethyl ether. During the evaporation process, the temperature is controlled at 30-50°C. After the recovery of dimethyl ether is complete, the extracted crude gardenia seed oil is released from the bottom of the separation kettle. The yield is 15-20%, an...

Abstract

The invention relates to a preparation method of high-quality cape jasmine seed oil rich in linoleic acid. Cape jasmine seeds are treated as raw materials, and the preparation method comprises the following steps: 1, conducting extraction, wherein microwave drying is conducted for drying the cape jasmine seeds, then the pulverization is conducted, subcriticality is adopted for conducting the extraction, and crude cape jasmine seed oil is obtained; 2, adopting different proportions of adsorption materials for conducting low-temperature decoloration and deodorization treatment, and the high-quality cape jasmine seed oil is obtained. The preparation method is easy to operate, the cape jasmine seed oil can be effectively extracted, no pollution is caused, no solvent residual exists, and the obtained cape jasmine seed oil is rich in the linoleic acid.

Description

technical field [0001] The invention relates to an extraction method of gardenia seed oil, in particular to a preparation method of high-quality gardenia seed oil rich in linoleic acid, belonging to the fields of natural extracts and food. technical background [0002] Gardenia (Gardenia jasminoides Ellis), belonging to Rubiaceae Gardenia, is a small evergreen shrub. Gardenia is born in the mountains and has strong adaptability. It is mainly distributed in tropical and subtropical regions. There are four kinds produced in China, which are gardenia, Hainan gardenia, narrow name gardenia and spoon leaf gardenia. Gardenia is also called yellow gardenia, mountain gardenia, and yellow fruit tree. Distributed from southwest to east, mainly in Henan, Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Taiwan, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Guizhou, Yunnan and other provinces. [0003] Gardenia is not only a kind of medicinal material and pigment raw material, but also a new oi...
