AI Technical Summary

Problems solved by technology

The oil extraction rate of the pressing method is low, and the important components such as unsaturated fatty acids in the oil are severely damaged under the high temperature state of pressing, which also leads to protein denaturation; however, there are solvent residues in the leaching method, the post-treatment process is complicated, the operation is cumbersome, and it is easy to cause environmental pollution.
At present, no more effective solution has been found

Embodiment 1

[0018] A kind of method adopting supercritical carbon dioxide to extract Xantho sorbifolium seed oil, comprises the following steps:

[0019] (1) Select fresh radix sorbifolium seeds, peel and separate them to obtain 100g of radix sorbifolium seed kernels, and crush the radix sorbifolium seed kernels to 10-120 mesh;

[0020] (2) Use supercritical carbon dioxide to extract the crushed sorbifolia seed kernels in step (1). The final sorbifolia seed kernels are placed in the extraction kettle of the supercritical fluid device. When the temperature of the separation kettle I reaches 30°C and the temperature of the extraction kettle reaches 35°C, the carbon dioxide gas storage tank is opened to charge the extraction kettle. pressure, when the pressure of the extraction kettle reaches 25MPa, adjust the flow rate of carbon dioxide to be 12L / h, keep the temperature and pressure, extract for 2 hours, collect the extract, and obtain the seed oil of Xanthomonas xanthus. scum.

Embodiment 2

[0023] A kind of method adopting supercritical carbon dioxide to extract Xantho sorbifolium seed oil, comprises the following steps:

[0024] (1) Select fresh radix radix sorbifolium seeds, peel and separate them to obtain 1 kg of radix sorbifolium seed kernels, and crush the radix sorbifolium seed kernels to 10-120 meshes;

[0025] (2) Use supercritical carbon dioxide to extract the crushed sorbifolia seed kernels in step (1). The final sorbifolia seed kernels are placed in the extraction kettle of the supercritical fluid device. When the temperature of the separation kettle I reaches 40°C and the temperature of the extraction kettle reaches 45°C, the carbon dioxide gas storage tank is opened to charge the extraction kettle. pressure, when the pressure of the extraction kettle reaches 28MPa, adjust the flow rate of carbon dioxide to be 12L / h, keep the temperature and pressure, extract for 1 hour, collect the extract, and obtain the seed oil of radix radix radix radiata, and t...

Embodiment 3

[0028] A kind of method adopting supercritical carbon dioxide to extract Xantho sorbifolium seed oil, comprises the following steps:

[0029] (1) Select fresh radix sorbifolium seeds, peel and separate them to obtain 100g of radix sorbifolium seed kernels, and crush the radix sorbifolium seed kernels to 10-120 mesh;

[0030](2) Use supercritical carbon dioxide to extract the crushed sorbifolia seed kernels in step (1). The final sorbifolia seed kernels are placed in the extraction kettle of the supercritical fluid device. When the temperature of the separation kettle I reaches 45°C and the temperature of the extraction kettle reaches 55°C, the carbon dioxide gas storage tank is opened to charge the extraction kettle. pressure, when the pressure of the extraction kettle reaches 30MPa, adjust the carbon dioxide flow rate to be 24L / h, keep the temperature and pressure, extract for 1.5h, collect the extract, and get the seed oil of Xanthomonas sorbifolium, and the remaining materi...

Abstract

The invention discloses a method for extracting shinyleaf yellowhorn seed kernel oil with a supercritical or subcritical fluid, which comprises the following steps: (1) selecting shinyleaf yellowhorn seed kernel, and pulverizing to 10-120 meshes; and (2) extracting the pulverized shinyleaf yellowhorn seed kernel in the step (1) with a supercutical fluid or subcritical fluid to obtain the shinyleaf yellowhorn seed kernel oil, wherein the residual material is shinyleaf yellowhorn dregs. Compared with the traditional pressing method, the method disclosed by the invention obviously enhances the oil extraction rate, and avoids the problems of severe damage of unsaturated fatty acids and other components in oil, and protein denaturation at high temperature in the pressing method. Compared with the leaching method, the method disclosed by the invention solves the problems of solvent residues, complex after-treatment process and high tendency of environmental pollution. According to the method disclosed by the invention, the oil extraction rate is not lower than 50%, the protein content in the shinyleaf yellowhorn dregs is not lower than 55g/100g, and the obtained oil product has high quality.

Description

technical field [0001] The invention relates to a method for extracting radix sorbifolia seed kernel oil from radix radix sorbifolium seed kernels, in particular to a method for extracting radishes sorbifolium seed kernel oil from radix sorbifolia seed kernels by using a supercritical or subcritical fluid. Background technique [0002] Xanthouras sorbifolia Bunge. is a plant of the Sapindaceae genus Xanthouras sorbifolia, a shrub or tree, also known as Xanthuras sorbifolia, Xanthuras sorbifolia, etc. It is distributed in various regions in northern my country. It is especially commonly used by the Mongolian people. Its kernels taste like chestnuts, benefit qi, moisten the five internal organs, calm the nerves, nourish blood and strengthen muscles. It can be used for a long time to treat enuresis, mental retardation, dementia and other diseases caused by low brain function. Its components are fatty oils, saponins, proteins and so on. The kernel of Xantho sorbifolium contains...
