Embodiment 1

[0019] The method for present embodiment refining tea seed oil may further comprise the steps:

[0020] A. Heat the tea seed oil crude product to 45-56°C, mix the solution with the inorganic acid solution, mix evenly, keep warm for 0.6 hours, centrifuge, remove the precipitate, and collect the tea seed oil centrifugate;

[0021] B, the centrifugal liquid is evaporated to a mass percentage concentration of 47%, to obtain the tea seed oil evaporation liquid;

[0022] C. Add lye to the tea seed oil evaporated liquid, adjust the temperature to 55°C-60°C, and keep warm for 45 minutes; wherein, the lye is 1.5% sodium hydroxide solution by mass percentage, and the tea seed oil evaporates The volume ratio of liquid to sodium hydroxide solution is 1:1;

[0023] D. After step C is finished, add a salt solution to carry out salting out, so that the mass percentage of solid matter in the tea seed oil is ≤0.06%, and obtain a tea seed oil salting out solution; wherein, the salt solution is...

Embodiment 2

[0027] The method for present embodiment refining tea seed oil may further comprise the steps:

[0028] A. Heat the tea seed oil crude product to 45-56°C, mix the solution with the inorganic acid solution, mix evenly, keep warm for 1.2 hours, centrifuge, remove the precipitate, and collect the tea seed oil centrifugate;

[0029] B, the centrifugal liquid is evaporated to a mass percentage concentration of 55%, to obtain the tea seed oil evaporation liquid;

[0030] C. Add lye to the tea seed oil evaporated liquid, adjust the temperature to 55°C-60°C, and keep warm for 37 minutes; wherein, the lye is 2% sodium hydroxide solution by mass percentage, and the tea seed oil evaporates The volume ratio of liquid to sodium hydroxide solution is 1:1.2;

[0031] D, after step C is finished, add salt solution to carry out salting-out, make the mass percent of solid matter in tea seed oil≤0.06%, obtain tea seed oil salting-out liquid; Wherein, described salt solution is 10% by mass perce...

Embodiment 3

[0035] The method for present embodiment refining tea seed oil may further comprise the steps:

[0036] A. Heat the tea seed oil crude product to 45-56°C, mix the solution with the inorganic acid solution, mix evenly, keep warm for 0.9 hours, centrifuge, remove the precipitate, and collect the tea seed oil centrifugate;

[0037] B, the centrifugal liquid is evaporated to a mass percentage concentration of 40%, to obtain the tea seed oil evaporation liquid;

Abstract

The invention discloses a method for refining tea seed soil, and relates to the technical field of vegetable oil refining. The method comprises the steps of heating a crude product of the tea seed soil, then mixing the heated tea seed soil with an inorganic acid solution, carrying out centrifugal separation, evaporation, alkali refining and salting-out, and filtering. According to the method, thesolid content of the tea seed soil is reduced by means of the step of salting-out; in a refining process, a ceramic membrane filter is used for filtering, so that colloid, pigment and other impuritiesare removed. The refining method provided by the invention does not involve the steps of high temperature treatment, thus avoiding the damage of high temperature to the nutrients in tea seed oil andimproving the quality of the refined tea seed oil. After the method is adopted, the refined tea seed oil is light in color.

Description

technical field [0001] The invention relates to the technical field of vegetable oil refining, in particular to a method for refining tea seed oil. Background technique [0002] Tea seed oil is refined from the fruit of Camellia oleifera, a plant of the genus Camellia in the family Theaceae. It is light yellow in color, clear and transparent, and has a delicate smell. Tea seed oil is a unique oil in my country. Its fatty acid composition is similar to that of olive oil, the best vegetable oil recognized in the world. Tea seed oil does not contain components that are difficult to digest and absorb. The content of unsaturated fatty acids is more than 90%, and it is rich in Containing various functional ingredients such as vitamins A, B, D, E, etc., it has the effect of preventing cardiovascular diseases such as hypertension, coronary heart disease, and atherosclerosis. [0003] The crude product of traditional tea seed oil obtained by pressing or solvent leaching needs to be f...
