Problems solved by technology

Most of them adopt the workshop-style pressing process, which not only has high cost and low yield, but also tea seeds contain more reducing sugars, which are prone to browning due to high temperature during the pressing process, making the oil darker, making the oil quality poor and The price is not high, the use is limited, and its pressed cake is also difficult to use
Some factories also use the leaching method, but the organic solvents used are volatile, and it is difficult for small factories to meet the requirements of safe production. The cost is high, the environment is polluted, and the solvents in the finished oil are easy to remain, and even the carcinogens exceed the standard, which endangers consumers. Healthy body

Embodiment Construction

[0014] It can be seen from the accompanying drawings that the dried camellia seed shells are crushed with a disc sheller to separate the kernels and shells, and the peeled camellia seed kernels are baked at 180°C for 30 minutes, then crushed and ground to a particle size of <10 μm. The pulverized and ground camellia seed slurry was uniformly mixed with water at a mass ratio of 1:4, heated and stirred at a temperature of 70°C for extraction, and the extraction reaction was carried out for 30 minutes under microwave radiation with a power of 800W. The extract liquid obtained by the reaction is separated by a decanter decanter centrifuge to separate emulsified oil and protein slurry. After adding a demulsifier to the emulsified oil and stirring to break the emulsified oil, add 10% hot water to wash, centrifuge to remove water residues, and vacuum dehydrate to obtain camellia oil. The method of extracting camellia oil by using microwave-assisted water substitution method has the c...

Abstract

The invention discloses a method for extracting camellia oil by using a microwave assisted aqueous extraction method, belonging to the technical field of grease preparation. In the method, dried tea seeds are husked, baked, crushed and ground and then are subjected to water feeding, microwave extraction, centrifugal separation, emulsion breaking, washing and vacuum dehydration to obtain the camellia oil. The method has the advantages of simpleness in process operation, favorable grease quality, high extraction speed, high extraction rate, less pollution to the environment and low cost and is suitable for industrial scale production.

Description

technical field [0001] The invention relates to the technical field of oil preparation, in particular to a method for extracting camellia oil by a microwave-assisted water substitution method. Background technique [0002] Camellia oleifera seed is one of the four major woody oil plants in the world. It is mainly distributed in Jiangxi, Hunan, Anhui, and Guangxi provinces in my country, with Hunan being the most. Camellia oil is the oil obtained by pressing or extracting camellia seed kernels. According to literature reports, camellia oil has a clear and fragrant taste, and the content of unsaturated fatty acids in its fatty acid composition-oleic acid and linoleic acid is as high as 83% to 90%. Long-term consumption is beneficial to prevent diseases such as arteriosclerosis, high blood pressure and obesity. It has the reputation of "Oriental olive oil" and "treasure in oil". [0003] In the main producing areas of camellia oleifera seeds in my country, the pressing method...
