Production method of natural tea seed oil free of refining

Abstract

A production method of natural tea seed oil free of refining includes the following steps: (1) seed selection: selecting full tea seeds with normal color and luster, free of mildew and impurity and drying the tea seeds; (2) shell removing: removing shells of the tea seeds through a husking machine and enabling kernels to be separated from the shells to obtain tea kernels; (3) low temperature drying: drying the tea kernels under the temperature of 70 DEG C to 98 DEG C till moisture content of the tea kernels reaches 9% to 13%; (4) squeezing: squeezing the dried tea kernels in an air pressure cylinder for 40 to 50 minutes with the pressure ranging from 20kPa to 90kPa; (5) filtering: filtering squeezed tea seed oil through filtering cloth; and (6) precipitation: placing the filtered tea seedoil statically and obtaining boiled oil for package to obtain products. The production method removes steaming, frying and smattering work procedures, does not require refining processes including dephosphorization, deacidification, deodorization, freezing and the like and retains pure natural activity of the tea seed oil. The obtained tea seed oil is light yellow, transparent and bright in colorand luster, free of bitter and odd smell and pure in smell and tastes good.

Description

technical field [0001] The invention relates to a production method of edible oil processing, in particular to a production method of non-refining natural tea seed oil. Background technique [0002] Edible oil is a necessary consumer product for people's life, and it is an important food that provides human body heat energy and essential fatty acids, and promotes the absorption of fat-soluble vitamins. With the rapid development of my country's economy and the substantial improvement of people's living standards, people's requirements for the quality and quantity of edible oil are also constantly improving. Eating natural, green and healthy oil products has become an important requirement for people to choose edible oil. Tea seed oil is derived from the woody plant tea tree, which is mainly distributed in the hilly areas of Hunan, Guizhou, Jiangxi, Guangxi, Anhui, Sichuan, Shaanxi and other provinces. It is far away from urban "three wastes" pollution sources, and is not po...

Problems solved by technology

This invention adopts the method of shelling first and then baking, which can not only prevent the harmful substances in the shell from penetrating into the tea kernels during the baking process, but also shorten the baking time, reduce energy consumption, and save energy; its disadvantages are: Camellia oleifera seeds have to go through the process of steaming and frying, and the high temperature of steaming and frying is easy to lose the nutrients in the oil, the active substances and the fragrance of the camellia oil itself

But the disadvantage is that the tea kernel needs to be crushed, which destroys its composition structure, and stacking and retting will make the tea seed oil not fragrant and pure enough

Its shortcoming is that during the oil refining process, while removing some harmful substances, it also loses most of the carotene and chlorophyll, which have the functions of inhibiting cancer cell proliferation, improving immunity, light absorption and anti-oxidation, and phytosterols are lost. 35%~40%, 70% loss of vitamin E, 80% loss of squalene; at the same time, trans fatty acids are produced during the high temperature deodorization process, and the activated clay used in decolorization may bring heavy metals, which will affect the quality and safety of edible oil. harm
