Problems solved by technology

Because this kind of camellia oil has not been refined, it contains more harmful substances, and it will produce thick smoke when cooking, which not only affects the environment, but also is harmful to the human body.
In recent years, some domestic oil companies and relevant units have conducted research on the refining process of camellia oil, and developed some tea oil refining processes suitable for industrial production, such as the Chinese patent "Camellia oil refining method with high nutrient content" (patent application No. 200910307817.2), this invention aims at the problem of excessive loss of camellia oil nutrients caused by excessive temperature in the prior art, and provides a method for refining camellia oil with high nutrient content. The main steps include: producing crude oil at room temperature; Add warm water, then use sedimentation separation method to remove the impurities and water in the lower layer; add sodium hydroxide solution, then use sedimentation separation method to remove water and soapstock; heat tea seed crude oil to 80 ℃ ~ 90 ℃, add 1 to 3 parts of activated clay , at -0.1MPa~-0.095MPa, cooled to 68℃~72℃ after 15~20 minutes, and then filtered with cotton cloth; deodorized camellia oil was obtained after distillation at a temperature of 140~150℃ and a vacuum of 200Pa to 260Pa; deodorized The camellia oil is cooled slowly and filtered under static pressure to obtain refined camellia oil

Embodiment 1

[0021] a, get 3000kg of fresh camellia oleifera seed as raw material, process according to conventional low-temperature cold pressing technology, make crude oil 450kg, standby;

[0022] b. Measure the acid value of the spare crude oil (the acid value measured in this example is 3.1%), heat to 55°C, stir for 2 hours while heating, and then add NaOH aqueous solution with a concentration of 35% (the amount of alkali added T is calculated according to the formula: T=7.13×10 -4 × crude oil weight × acid value, the amount is 2.98 kg), precipitated for 12 hours, filtered off soapstock, and obtained 410 kg of alkali-refined crude oil, which was set aside;

[0023] c. Slowly raise the temperature of the spare alkali-refined crude oil to 85°C, add 0.2% by weight of alkali-refined crude oil and a 50% sodium chloride aqueous solution, stir evenly while adding, and then, at 60-80°C Precipitate at constant temperature for 2 hours, filter out the soapstock again; then add hot water above 80...

Embodiment 2

[0028] This embodiment is a further processing carried out on the basis of Embodiment 1.

[0029] a, get the high-quality camellia oil 110kg prepared by embodiment one and place in the container, add and account for high-quality camellia oil weight 0.5-5%, concentration is 10% Na 2 CO 3 aqueous solution (in this case Na 2 CO 3 The addition amount of aqueous solution is 50 kilograms), stir evenly, leave standstill, separate, collect 82 kilograms of upper strata oil solutions, set aside;

[0030] b. Put the reserved upper layer oil solution into the extraction tank, add neutral activated carbon accounting for 1-10% of the weight of the upper layer oil solution (in this example, the amount of activated carbon added is 7 kg), fully stir, filter, remove activated carbon, etc. For impurity particles, collect the tea oil after filtration for subsequent use, repeat the above steps 3 times; 70 kg of tea oil after filtration, for subsequent use;

[0031] c. Put the spare camellia oil ...

Abstract

The invention discloses a preparation method of high-quality tea oil, relating to the technical field of biomedicine and food processing. The process flow comprises the steps of: preparing crude oil; performing alkali refining to remove soapstock; washing by water to remove colloid; decoloring by using argil; deodorizing at high temperature and the like. The preparation method of the high-quality tea oil has the characteristics that the activity of target components in the tea oil can be maintained, useless or harmful impurities can be removed, the energy consumption is low, the environmental pollution is light, the production period is short and the like; and the preparation method of the high-quality tea oil can be used for processing the tea oil suitable for common people, and the health tea oil suitable for pregnant women and children.

Description

technical field [0001] The invention relates to the technical fields of biomedicine and food processing, in particular to a method for preparing high-quality camellia oil. Background technique [0002] Camellia oleifera is a unique woody oil crop in my country, and it is also an oil crop vigorously developed in China. The comprehensive utilization value of camellia oleifera is very high. It is rich in unsaturated fatty acids, monounsaturated fatty acids, vitamin E, squalene, tea polyphenols and other biologically active substances. Among them, monounsaturated fatty acids can improve blood antioxidant capacity, reduce cholesterol, It can prevent the occurrence of cardiovascular and cerebrovascular diseases, and can also reduce the incidence of diseases caused by metabolic disorders such as insulin-resistant diabetes. Not only does it not accumulate in the internal organs and subcutaneously, but it also prevents fat deposition and prevents obesity. In medicine, tea oil is use...
