Problems solved by technology

The pressing method is divided into cold pressing and hot pressing, but both of them have the problem of low oil yield, and the residual oil content in the cake is generally 7-10%; the salient feature of the solvent extraction method is the high oil yield, Low residual oil rate, low labor intensity, high production efficiency, small degree of protein denaturation in the meal, good quality, easy to realize large-scale production and production automation, etc., is the main method of tea seed oil extraction at present
The solvents used are all extracted from petroleum fractions from the earliest petroleum ether, 90# solvent oil, 6# solvent oil to the current "vegetable oil extraction solvent" and n-hexane. Although the standards are getting stricter, there are Contains aromatic hydrocarbons that are harmful to the human body, sulfur will corrode equipment, and the extracted camellia oil has many disadvantages such as darker color

Embodiment 1

[0041] An embodiment of the tea seed oil extraction method of the present invention, the method includes the following steps:

[0042] (1) Pretreatment: Clean the camellia seeds, peel them, put them in an oven at 70°C for 24 hours, and crush the dried camellia seeds in a high-speed pulverizer (2800r / min) for 3 minutes;

[0043] (2a) Weigh 30g of crushed camellia seeds, wrap them with filter paper, put them into the extraction tube of Soxhlet extractor, measure 150ml of sec-butyl acetate solvent, and add to the extraction bottle of Soxhlet extractor;

[0044] (2b) Turn on the condensed water integrated into the condenser of the Soxhlet extractor, open the jacketed incubator to heat it, and start to calculate the extraction time when the first drop of pure solvent in the condenser drips. The extraction time is 3 hours; during the extraction process In the middle, by adjusting the power of the sleeve warmer, the heat dissipation effect of the Soxhlet extractor and the contact area betwe...

Abstract

The invention discloses a tea-seed oil extraction method which comprises the following steps that (1), pretreatment is performed: oil-tea camellia seeds are smashed, and (2), sec-butyl acetate is taken as a solvent, and tea-seed oil is extracted with a soxhlet extraction method or a mixing extraction method. The tea-seed oil extraction method takes the oil-tea camellia seeds as raw materials and sec-butyl acetate as the leaching solvent, and sec-butyl acetate is a green and environment-friendly solvent completely free from arene and sulfur, so that compared with the existing commonly-used leaching solvent, the extracted tea-seed oil is safer to eat due to the environment-friendly characteristic of sec-butyl acetate; sec-butyl acetate is free from sulfur, so that corrosion to a system is reduced, and the service life of equipment can be prolonged; the purity of adopted sec-butyl acetate is higher; the extracted tea-seed oil is few in impurity; the quality of the tea-seed oil is ensured; in addition, sec-butyl acetate is an ester solvent, and has better solubility to oil, so that the extracting power to the tea-seed oil is improved; the content of residual oil in pulp can be reduced; a yield of the oil is increased; and the extraction cost is lowered.

Description

Technical field [0001] The invention relates to a method for extracting tea seed oil, in particular to a method for extracting tea seed oil using a solvent extraction method. Background technique [0002] Tea seed oil is a unique woody oil in my country. It is a colorless or light yellow oily liquid. Its fatty acid composition is similar to that of olive oil. It has the reputation of "Oriental Olive Oil". It can reduce cholesterol content, prevent cardiovascular diseases, and improve immunity. Its function is also an important raw material for many cosmetics and medical supplies. [0003] The extraction methods of tea seed oil mainly include pressing method, solvent extraction method, water enzymatic method and supercritical carbon dioxide extraction method. At present, the extraction of tea seed oil in my country generally adopts pressing method and solvent extraction method. The pressing method is divided into cold pressing and hot pressing, but both have the problem of low oil ...
