Problems solved by technology

[0012] Chinese patent 200910307817.2 aims at problems such as excessive loss of camellia oil nutrients due to excessive temperature in the prior art, and provides a method for refining camellia oil with high nutrient content. The main steps include: preparing crude oil at normal temperature; adding warm water, and then using Remove impurities and water in the lower layer by sedimentation separation; add sodium hydroxide solution, and then remove water and soapstock by sedimentation separation; heat tea seed crude oil to 80°C-90°C, add 1-3 parts of activated clay, at -0.1MPa At ~-0.095MPa, after 15-20 minutes, cool to 68°C-72°C, and then filter with cotton cloth; at a temperature of 140-150°C, a vacuum of 200Pa to 260Pa, after distillation, deodorized camellia oil is obtained; deodorized camellia oil is slowly cooled Static pressure filtration to obtain refined camellia oil
[0013] Said patent discloses these basic technological methods of cold-pressing camellia oil at present, but the process is complicated, the technological conditions are high, and a variety of chemical reagents or auxiliary agents are required. It is easy to have problems in safety, taste, flavor, nutrition and health, etc.
[0014] The low-temperature crystallization purification process often used in existing methods is also mostly too simple. Although it can basically achieve the purpose of removing high-melting point saturated fat and solve the problem of solidification or precipitation during low-temperature storage, the control of the cooling process is not specific enough. Crystallization The time is very long, resulting in low production efficiency and high energy consumption, and there is no disclosure of the crystallization of high melting point saturated fat, and the adsorption of harmful substances in the oil such as wax, benzopyrene, heavy metals, pesticide residues, etc. during the crystallization process remove effect problem

Embodiment 1

[0040] The following method is used to prepare a kind of tea oil:

[0041] A. Make the raw material of the special -grade virgin tea oil: Take fresh tea seeds and open it naturally; control the water at 8 quality%; remove all the seed shells of the oral tea seeds to get the oral tea seed kernels;

[0042] B. Virgin: Squeeze the categorine seeds obtained by the step A, and squeeze the seed temperature of the oil. The seed temperature is the environmental temperature, that is, the temperature, and the temperature of the squeezing and the oil of the squeezing oil is lower than 60 ° C.Tea withered;

[0043] C. Frozen removal: Put the virgin tea oil into the freezer tank, and freeze and cool down according to the following three stages.The first stage: first cool down at a speed of 2.0 ° C / hour to 20 ° C, maintain 15 hours, and the mixing speed is 50 R / min; then the speed of 2.0 ° C / hour is cooled to 10 ° C, maintained for 5 hours, the mixing speed is 50 to 50R / min; In the second stage...

Embodiment 2

[0047] Adopting the basic method as the embodiment 1, a special -grade virgin tea oil is prepared. The difference is that before the program in the step C is frozen and cools down, the rough product of the virgin mountain tea oil is added, and the tea obtained from the step B is added to the tea obtained from the step b dry.The 60 -mesh -meter fine powder is grinded. The amount of tea withered powder is 2: 100 with the quality ratio of the rough products of the virgin mountain tea. It acts as a crystal nucleus during the frozen crystallization process to improve the purification effect of refrigeration crystal.

Embodiment 3

[0049] Adopting the basic method as Example 1, a special -grade virgin tea oil is prepared. The difference is that before the program in the step C is frozen and cooling, the rough products of the virgin mountain tea oil are added to the rough products of the virgin mountain.The 200 meter -made powder, the amount of tea dry powder is 0.05: 100 with the quality ratio of the rough tea oil products of the virgin mountain. In the process of frozen crystal, it acts as a crystal nucleus to improve the purification effect of refrigeration and crystal.

Abstract

The invention discloses super virgin camellia oil and a preparation method thereof. The preparation method comprises the following process steps: naturally air-curing or air-drying and unshelling camellia seeds to obtain camellia seed kernels; pressing first camellia seed juice by using a cold press, wherein the feeding temperature of the camellia seed kernels is the environment temperature; controlling the barrel temperature and the expressed oil temperature to be lower than 60 DEG C to obtain a virgin camellia oil crude product; performing programmed cooling and freezing, grain growth, impurity removal and filtration to obtain the super virgin camellia oil. According to the method, a chemical reagent or a chemical aid is not added, the obtained camellia oil is pure in flavor, tastes fresh and cool, does not contain harmful ingredients such as metal, pesticide residue and benzopyrene, and does not contain trans-fat acid; the color, the flavor and the taste are perfect; original active nutritional ingredients of the camellia oil are better maintained; the quality is superior to the first-grade national standard.

Description

Technical field [0001] The present invention involves a kind of woody vegetable oil and its preparation methods, especially a kind of tea oil and its preparation methods, especially a special -grade virgin tea oil and its preparation method. Background technique [0002] Camellia is a unique oil resource in my country. Due to the lack of resources abroad, processing and development is very small.At present, the processing of cash tea in my country is still "rough and early". It is mostly used as a traditional processing method. When the scale is small and the technology is backward, the cashmeal seeds have a high temperature and long temperature. Deep color, large processing energy consumption and high cost, can also lead to damage and loss of biological activity such as tea saponin, polysaccharides, trace nutritional components such as tea saponin, polysaccharides, and trace nutrition.It has been revealed that the storageability of hair tea seed oil is better than refined tea se...
