Embodiment 1

[0023] A processing method of high-quality camellia oil, comprising the following steps:

[0024] (1) Pretreatment of camellia seeds: peel the fresh camellia seeds, dry them in the sun, peel off the camellia seeds and ripen them;

[0025] (2) primary pressing: the ripe camellia seed is pressed at a temperature of 50° C. to obtain primary crude oil and tea dry;

[0026] (3) Re-extrusion: pressing the tea dry at a temperature of 60°C to obtain secondary crude oil;

[0027] (4) Refining: After mixing the crude oil obtained twice and decolorizing by silica gel column chromatography, put the camellia oil in a low temperature environment of about 5°C to crystallize, then let it stand for 48 hours to grow crystals, release the crystalline solid fat, and then use the plate frame After the filter is pressed to remove impurities, the finished high-quality camellia oil is obtained.

[0028] The eluent in the silica gel column chromatography is a 1:25 mixed solution of petroleum ether: ...

Abstract

The invention discloses a processing method of high-quality camellia oil, and belongs to the technical field of food processing. The processing method of high-quality camellia oil comprises the following steps of pretreatment of camellia seed, primary squeezing, repeated squeezing, refining and filtering, and obtaining tea oil. The camellia oil prepared through the invention is pure and thick in fragrance, cool in taste; color, smell and taste are just right; besides, the original active nutrient components of the camellia oil is well reserved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing method of high-quality camellia oil. Background technique [0002] Camellia oil is made from the mature seeds of Camellia oleifera or small-leaved camellia oleifera seeds, and the fatty oil is obtained by pressing, leaching and other methods. Camellia oleifera seed oil is a pure natural high-grade woody edible oil. It is of high quality, natural and healthy, and it is a treasure among oils. [0003] Cold-pressed camellia oil is to extract vegetable oil under low temperature conditions with huge pressure of physical machinery, so it is called cold-pressed because the processed camellia oil seeds have not been steamed and fried in the traditional hot-pressed process, and the oil in the raw materials is still distributed. In the undeformed protein cells, so the cold-pressed camellia oil retains many inherent ingredients in camellia oil seeds, such a...
