Problems solved by technology

Although the pressed oil has a high degree of retention of various nutrients, hot pressing still destroys the activity of some nutrients in the tea seed oil due to heating; the traditional low-temperature pressing of the traditional soil method produces camellia oil with black color and bitter taste, which is not suitable for direct consumption
In addition, the tea seed oil is produced by low-temperature pressing method. After shelling, the tea seed kernel has a high oil content, it is difficult to pressurize, and it is easy to knot the chamber. Ordinary oil presses cannot operate normally.
Moreover, there are various sources of tea seeds, and the oil composition and active components vary greatly, resulting in problems such as low oil yield and high residual oil.

preparation example Construction

[0025] The high-purity camellia seed oil pressing preparation method of one embodiment comprises the following steps:

[0026] S110. Seed selection: select the seeds of the alpine camellia oleifera tree, remove disabled and diseased fruits, and then place them in a ventilated room for stacking and retting to make the alpine camellia oleifera seeds crack naturally.

[0027] Specifically, the mature seeds of alpine camellia oleifera trees, that is, camellia oleifera fruit, are selected. After removing the disabled and diseased fruits, those with similar quality are screened and piled up. They are placed in a ventilated room and stored at room temperature for stacking. The stacking time is 10 to 30 days. Camellia seeds are naturally cracked. Camellia oleifera seeds are further matured by stacking retting, and its soluble sugar and other organic matter are fully converted into oil, which improves the oil yield and oil quality.

Embodiment 1

[0051] S110. Seed selection: select the seeds of alpine camellia oleifera trees, remove disabled and diseased fruits, and then place them in a ventilated room for stacking and retting for 10 days. During this period, turn the pile every 2 to 3 days and remove moldy and rotten fruits in time to make the alpine camellia oleifera seeds natural cracking.

[0052] S120, treatment of camellia oleifera seeds, extracting camellia oleifera seeds from the cracked alpine camellia oleifera fruit, screening and cleaning, and then shelling the camellia oleifera seeds to separate the kernel and shell. Through the camellia seed treatment step, dehulled and screened and graded tea seed kernels are obtained.

[0053] S130. Freeze-drying the tea seed kernels, rinsing the tea seed kernels separated from the camellia oleifera seeds with clean water, draining and crushing into granules, with a particle size of 1~1.5mm; freezing at -45°C for 4 hours, taking them out and putting them under a pressure...

Embodiment 2

[0059] S110. Seed selection: select the seeds of alpine camellia oleifera tree, remove disabled and diseased fruits, and then place them in a ventilated room for stacking and retting for 15 days. During this period, turn the pile every 2 to 3 days and remove moldy and rotten fruits in time to make the alpine camellia oleifera seeds natural cracking.

[0060] S120, treatment of camellia oleifera seeds, extracting camellia oleifera seeds from the cracked alpine camellia oleifera fruit, screening and cleaning, and then shelling the camellia oleifera seeds to separate the kernel and shell. Through the camellia seed treatment step, dehulled and screened and graded tea seed kernels are obtained.

[0061] S130. Freeze-drying the tea seed kernels, rinsing the tea seed kernels separated from the camellia oleifera seeds with clean water, draining and crushing into granules, with a particle size of 1.5~2.5mm; freezing at -47°C for 4.5h, taking them out and placing them at 70Pa The press...

Abstract

The invention relates to a squeezing preparation method for high-purity mountain tea-seed oil and prepared tea-seed oil capsules. The preparation method comprises the steps: carrying out seed selecting and stack retting till natural cracking; stripping oil tea seeds, and carrying out kernel-shell separation; crushing tea seed kernels into granules, and carrying out low-temperature freezing and vacuum drying; carrying out primary squeezing, so as to squeeze out 30% to 40% of crude oil and prepare tea seed cakes; carrying out secondary squeezing, so as to squeeze out remaining crude oil; carrying out standing oil clarifying, so as to settle impurities in the crude oil and achieve oil-water separation; and carrying out filtering, selecting crude oil of a middle-upper section of an oil clarifying tank, carrying out centrifugal filtering-standing cycling for 2 to 3 times, and carrying out refining, thereby preparing the high-purity mountain tea-seed oil. According to the method, the retention rate of effective ingredients is high, the oil extraction rate is high, the oil quality is high, and the tea-seed oil and the tea-seed oil capsules, which are suitable for being directly eaten, canbe prepared without decolorization and deodorization; and an entire process is free of any chemical assistant, pure physical methods are adopted, and thus, natural flavors and fruity flavors of mountain tea-seed oil are effectively reserved.

Description

technical field [0001] The invention relates to the technical field of edible oil production technology, in particular to a method for preparing high-purity camellia seed oil by pressing and the prepared tea seed oil capsule. Background technique [0002] The physical and chemical properties of tea seed oil are similar to those of olive oil, in which the unsaturated fatty acid content exceeds 80%, especially the linoleic acid content is as high as 20.6%. The main component of camellia oil is glycerol trioleate, which contains sterols, triterpenoids, tocopherols, etc., which is beneficial to the prevention and treatment of cardiovascular and cerebrovascular diseases, obesity and many other affluent diseases, improves human immunity and the function of the gastrointestinal tract, and is beneficial to intellectual development , for almost everyone. The fatty acid composition of camellia oil is similar to that of olive oil. It is called "Oriental olive oil" and is a natural, sa...
