Detailed Description
The invention provides a camellia oil refining method, which comprises the following steps:
1) mixing the crude camellia oil with magnesium silicate under stirring, and mixing with water under stirring to obtain a stirred substance;
2) heating the stirred material obtained in the step 1) to 110-120 ℃ at a constant speed under a stirring state, cooling and filtering to obtain a finished camellia oil product.
The camellia crude oil is mixed with magnesium silicate under stirring, and then is mixed with water under stirring to obtain a stirred material.
The preparation method of the camellia crude oil is not particularly limited, and the conventional preparation method for preparing the camellia crude oil is adopted.
In the invention, the magnesium silicate is preferably food grade magnesium silicate, and the purity of the food grade magnesium silicate is preferably more than or equal to 99%. In the invention, the magnesium silicate is preferably 1.5-3% of the mass of crude camellia oil. In the invention, the magnesium silicate has the functions of removing acid value and peroxide value in oil, and reducing color and luster and benzo (a) pyrene.
In the invention, the water is preferably domestic water, and the water is preferably (0.1-0.4)% of the mass of the camellia crude oil. In the present invention, the purpose of adding water is to accelerate the absorption and sedimentation of the phospholipid, facilitating its filtration.
In the invention, the stirring time of the camellia crude oil and the magnesium silicate is preferably 5-10 min; the mixing time with water is preferably 5-10 min. In the present invention, the stirring speed is preferably 30 to 60 rpm. In the invention, the container pressure of the stirrer is kept below 0.09MPa, so that the stirrer is prevented from being exposed to air, and the formed camellia product oil is prevented from being unstable.
The obtained stirred material is heated to 110-120 ℃ at a constant speed under stirring, cooled and filtered to obtain the camellia finished oil.
In the present invention, the stirring speed is preferably 30 to 60 rpm. In the present invention, the time for raising the temperature is preferably 2 hours. In the invention, the temperature is uniformly increased to 110-120 ℃ so that the magnesium silicate has better adsorption property. Too high a temperature will cause the oxidation of the grease to be accelerated.
In the present invention, the filtration is preferably performed under stirring, and the stirring speed is preferably 30 to 60 rpm. In the invention, the oil is filtered by using 70-90-mesh filtering cotton cloth and food-grade filtering paper, the oil is automatically filtered by utilizing a high potential difference, and then the oil is conveyed and filtered by using a vortex pump until the filtering is finished, so that a finished camellia oil product is obtained.
The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.
