Embodiment 1

[0030] (1) Collection and drying of green tea seeds: collect mature green tea seeds, store them indoors for 8 days, and dry them in the sun until the moisture content is within 12%.

[0031] (2) Green tea seed dehulling: the green tea seeds treated in step (1) are dehulled with a sheller to obtain tea kernels.

[0032] (3) Low-temperature drying of tea kernels: select the obtained tea kernels, remove impurities, moldy, moth-eaten, and deformed bad tea kernels, and dry the selected tea kernels at low temperature in a baking machine. The drying temperature is controlled within 60°C, and the moisture content of the dried tea kernels is controlled within the range of 4-8%.

[0033](4) Pre-mixing of tea kernels and rice husks: Mix the dried tea kernels and rice husks evenly in step (3), the mixing weight ratio is tea kernels: rice husks = 12:1, and the rice husks are clean and dry rice Husk, the moisture content of rice husk is within 10%.

Abstract

The invention discloses a production method of squeezed green tea seed oil. The production method comprises the main steps of green tea seed collecting and drying, green tea seed hulling, low-temperature drying of tea seed kernels, tea seed kernel and rice hull premixing, low-temperature mechanical squeezing, filtering and purifying and the like. The oil yield of the squeezed tea seeds accounts for over 90% of the total oil content of the tea seeds, and the residual oil ratio is within 10%, so that the problem of low oil yield of the traditional green tea seed oil squeezing method is solved, and the oil yield is increased by over 10% as comparison with the oil yield obtained by using the traditional squeezing technology. By using the direct squeezing method, the production capacity is improved, the production cost is reduced, the processing time is shortened, and no waste water and waste gas are generated. The produced squeezed commercial oil prepared from the green tea seeds is moderate in color and luster, few in impurity, free of bitterness and capable of ensuring that the quality of a finished product of green tea seed oil is up to the national edible oil standard while retaining original fatty acid components, tea polyphenol and natural active beneficial components to the maximum extent.

Description

technical field [0001] The invention relates to a production method of tea seed oil, in particular to a production method of pressed green tea seed oil. Background technique [0002] Tea tree and Camellia oleifera belong to the same order, same family, and the same genus, that is, Genus camellia L.. Camellia plants can be divided into 22 groups, among which, the tea group is the most widely used as tea drinks, the camellia group is developing rapidly as high-grade edible oil, and the camellia group plants are widely planted as ornamental plants because of their bright colors. Tea seeds are the seeds grown from the tea tree in the tea group. For a long time, tea seeds have been used as waste by-products, and only a very small part has been utilized. China is a big tea-producing country in the world, with rich tea seed resources and more than 1.8 million hectares of tea gardens. Seventy percent of the provinces in the country have tea industry, and there are about 80 million...
