Problems solved by technology

[0002] Most of the existing camellia oil preparation methods use drying, crushing, flaking, steaming and frying at a high temperature above 110°C, and then press the oil through high-temperature hot pressing. The processing procedures are relatively complicated, the equipment investment is large, and the production cost is high. The oil color is darker and the quality is poor. It must go through deacidification, dehydration, decolorization, deodorization, degreasing and other refining processes before it can become first-class pressed oil. The refined oil yield is low, and the natural flavor of camellia oil is lost after refining.

Embodiment 1

[0009] (1) Spread the fresh camellia seeds in a cool and ventilated place, let the peels split naturally, then remove the peels, and dry the peeled camellia seeds in the sun or at 70°C until the water content is 10%;

[0010] (2) Hulling: peel the dried camellia seeds, separate the kernel and shell, select the tea seed kernels, remove discoloration, deterioration, and immature tea kernels, and control the shell content in the kernels to 1% Inside, tea seed husks contain more pigments, reducing the amount of tea seed husks will help to obtain pressed oil with lighter oil color;

[0011] (3) heating the selected tea seed kernels to 75°C under a vacuum degree of -0.09MPa, drying until the water content is 2%, and then naturally cooling to room temperature;

[0012] (4) Mix 4kg of chaff into 100kg of tea seed kernels cooled to room temperature, and stir evenly. The bran helps to increase the pressure, produce more oil, and reduce the amount of slag in the oil; then use a screw pre...

Embodiment 2

[0018] (1) Spread the fresh camellia seeds in a cool and ventilated place, let the peels split naturally, then remove the peels, and dry the peeled camellia seeds at 80°C until the moisture is 13%;

[0019] (2) shelling the camellia seeds after moisture drying to separate the kernel and the shell, requiring that the shell content in the kernel be controlled within 1%;

[0020] (3) Heat the tea seed kernel to 110° C. under a vacuum degree of -0.085 MPa, dry until the water content is 4%, and then naturally cool to room temperature;

[0021] (4) 100kg of tea seed kernels cooled to room temperature are mixed with 5kg of bran husks, stirred evenly, and then cold pressed to obtain 41.8kg of slag-containing pressed oil;

[0022] (5) Heating the squeezed oil containing slag to 80° C., filtering to remove impurities, so that the impurity content in the oil is less than 0.1%, and obtaining 40.96 kg of pressed oil;

[0023] (6) Add 204.8 g of activated carbon to 40.96 kg of pressed oil...

Abstract

The invention relates to a preparation method of pure camellia oil. Impurities are removed by filtration in a pure physical cold pressing way to obtain the pure camellia oil and the active components of the camellia oil are effectively reserved by a pure physical method without using any chemical agents during oil refining. The invention has light oil color, can obtain the camellia oil fit to a national GB1 1765-2003 pressed tea-seed oil standard without processing processes, i.e. deacidification, decoloration, deodorization, and the like, during the oil refining, reservess the natural flavor and aroma of the camellia oil, and has simple process, low cost and high oil yield.

Description

technical field [0001] The invention relates to a preparation method of pure camellia oil. Background technique [0002] Most of the existing camellia oil preparation methods use drying, crushing, flaking, steaming and frying at a high temperature above 110°C, and then press the oil through high-temperature hot pressing. The processing procedures are relatively complicated, the equipment investment is large, and the production cost is high The oil has a darker color and poor quality. It must undergo refining processes such as deacidification, dehydration, decolorization, deodorization, and degreasing before it can become first-grade pressed oil. The refined oil yield is low, and the natural flavor of camellia oil is lost after refining. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of pure camellia oil with simple and convenient process, effectively retaining the active ingredients of camellia oil and natural fla...
