Embodiment

[0026] Embodiment: Take 100 kg of dehulled camellia oleifera seed kernels containing 50.2% oil as raw material, use water as soaking agent, and ultrasonically soak the camellia oleifera kernels under normal temperature conditions to remove tea saponin. Ultrasonic the Camellia oleifera seed aqueous solution for 20-25 minutes every hour, change the water every 5 times of ultrasound, change the water three times in total, remove the soaking water, collect the Camellia oleifera seed kernel, dry and pulverize the Camellia oleifera seed kernel;

[0027] Immerse the dried and pulverized Camellia oleifera seed kernels in No. 6 extraction solvent oil at a ratio of 4:1 to the oil-plant ratio, and add tea seed oil as a thickener at a ratio of 3.5% of the volume of No. 6 extraction solvent oil and stir evenly. Then do low-pressure treatment and process the Camellia oleifera seed kernel with the method of ultrasonic wall breaking at the same time, do first-level ultrasonic wall breaking tre...

Abstract

The invention discloses a method for extracting tea-seed oil, which is used for extracting the tea-seed oil by carrying out ultrasonic wall-breaking treatment on camellia seeds, and comprises the following steps of: soaking shell-less camellia seeds with water to remove tea saponin; immersing the dried and crushed camellia seed kernels into No.6 extraction solvent oil, adding a proper amount of tea seed oil as a thickening agent, uniformly stirring, carrying out low-pressure treatment, and carrying out multistage treatment on the camellia seed kernels by using an ultrasonic wall breaking method; centrifugally separating, and collecting a No.6 extraction solvent oil solution; distilling and separating the No.6 extraction solvent oil solution to obtain high-quality tea seed oil with a high oil yield. According to the invention, during ultrasonic wall-breaking treatment, a certain amount of tea seed oil is added to improve the viscosity of petroleum ether, the ultrasonic cavitation effectis improved, and the camellia seed wall breaking effect is further improved. Ultrasonic wall breaking and low-pressure treatment are combined, so that the cavitation generation time is shortened, thecavitation effect is improved, the ultrasonic wall breaking efficiency is improved, and the oil yield is increased.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to a method for extracting tea seed oil. Background technique [0002] Tea seed oil is extracted from the fruit of Camellia oleifera in the family Theaceae. Tea seed oil is a unique oil in my country. Its fatty acid composition is similar to olive oil, the best vegetable oil recognized in the world. Tea seed oil is unsaturated The fatty acid content is above 90%, and it is rich in protein and vitamins A, B, D, E, etc., especially the rich linolenic acid it contains is necessary for the human body but cannot be synthesized. [0003] A method for extracting tea seed oil with the application number "CN201710901191.2" in the prior art. The extraction method steps include: selecting peeled fresh camellia seeds, drying at 65-75°C, shelling and crushing, and Use petroleum ether as the extractant for ultrasonic extraction, use Soxhlet extractor for reflux extraction, collec...
