Embodiment Construction

[0022] Now take the laboratory implementation as an example, and the non-limiting examples are described as follows:

[0023] The camellia seed is dried under vacuum at 40-60°C, then shelled and pulverized. Take 200g of pulverized raw material powder, add 600mL of n-hexane extractant, keep it in a closed state, add the material liquid into the ultrasonic extractor at the same time, extract at room temperature for 30min, then increase the temperature to 55°C, and keep the extraction for 45min. After the extraction, Suction filtration to remove dregs to obtain the suction filtration mixture, centrifuge at 2500r / min for 20min, and obtain the supernatant as the extract. Evaporate the extract under reduced pressure with a rotary evaporator, recover the solvent to obtain camellia oil, and then vacuum-dry the obtained camellia oil to obtain the final camellia oil product.

Abstract

The invention provides an ultrasound-assisted tea oil extraction method. Tea seeds are used as raw materials and the ultrasound-assisted tea oil extraction method comprises the following steps of: harvesting and sorting tea seeds, drying, shelling and crushing, sieving, weighing, adding an extraction solvent, performing ultrasound-assisted extraction, separating, evaporating and recovering the solvent, and obtaining tea oil. The extraction process is simple, processing cost is low, extraction efficiency is high, and tea-oil tree resources can be fully utilized.

Description

technical field [0001] The invention relates to a method for extracting camellia oil, in particular to a method for extracting camellia oil assisted by ultrasonic waves. Background technique [0002] Camellia oleifera (Camellia oleifera Abel.) is a plant of the Theaceae family Camellia, which originated in China and has a long history of cultivation. Camellia oil (Camellia oil) is the edible oil obtained by pressing the mature seeds of Camellia oleifera, also known as tea seed oil and camellia oil. It is a unique woody oil in my country. "Oriental olive oil" reputation. The content of unsaturated fatty acids in camellia oil - oleic acid, linoleic acid and linolenic acid is as high as 83% - 95%, which is the crown of various edible vegetable oils. Tea oil contains vitamin E, vitamin D, vitamin K and carotene. Camellia oil also contains biologically active substances such as camellia saponin, tea polyphenols and squalene. [0003] At present, there are generally methods for...
