[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...
