A kind of production method of freshly squeezed tea seed oil

Abstract

The invention discloses a production method for freshly-squeezed tea-seed oil. The production method concretely comprises the following steps: (1) picking of tea seeds, where, raw materials must be manually picked tea seeds; (2) husking of the tea seeds through a machine; (3) screening and drying; (4) storage, in which, dried tea seeds are subjected to nitrogen-filled preservation storage; (5) cleaning and grading and hulling separation, in which an impurity-removal grader is adopted to remove impurities from tea seed subjected to low-temperature storage; (6) conditioning and crushing; (7) low-temperature squeezing; (8) filtration, in which crude oil squeezed from tea seeds is obtained; (9) nitrogen pressing of filtered tea seeds into a winterization tank arranged on the second floor; and (10) natural flowing of warmed tea-seed oil to a plate-and-frame filtering machine arranged on the first floor for filtration. Since the raw materials are fresh and the whole production process is performed at low temperature and with nitrogen filled, natural effective constituents, such as vitamin E, squalene and phytosterol, are kept in tea-seed oil, and production of harmful substances, such as peroxide and benzopyrene, is prevented in a conventional production process.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of freshly squeezed tea seed oil. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae. It is a kind of evergreen, long-lived and high oil-bearing fruit tree species unique to China. It is one of the four major woody edible oil source tree species. Originated in China, only a few countries in Japan and Southeast Asia have sporadic distribution, and only China has large-scale cultivation. It can be said that Camellia oleifera is a treasure bestowed by nature on the land of China; Camellia oleifera grows in the subtropical mountains of southern China. The living climate is warm and humid, the ecological environment is excellent, and there is no pollution. The whole growth process does not require auxiliary means such as chemical fertilizers and pesticides, so the fruit has no residues of chemical fertilizers and pesticides...

AI Technical Summary

Problems solved by technology

[0005] However, in the traditional production process of tea seed oil, the use of high temperature leads to the production of harmful substances such as benzopyrene, which makes the hygienic indicators such as acid value and peroxide value of the pressed oil exceed the standard.

At the same time, excessive refining processes such as alkali refining, decolorization, and deodorization will cause the loss of effective nutrients in camellia oil, increase impurities, and increase energy consumption in the production process.
