Problems solved by technology

The tea seed oil produced by hot pressing is easy to lose the natural nutrients, active substances and inherent fragrance in the tea seed oil, and the color of the tea seed oil obtained is dark, so it must be further refined and processed, which consumes a lot of energy.
The production of tea seed oil by low-temperature pressing method is difficult for shelling and separation of shell kernels. After shelling, the oil content of tea seed kernels is high, 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.

Embodiment 1

[0022] 1) Camellia oleifera fruit treatment: Screen the harvested camellia oleifera fruit, remove the bad fruit, and then place it in a ventilated area for 12 days. During this period, turn the pile once a day and remove the moldy and rotten fruit in time; For 3 days, the camellia seed was cracked naturally and the camellia seed was peeled off, and those that failed to peel off naturally were artificially separated;

[0023] 2) Camellia oleifera seed treatment: sieve the separated camellia oleifera seeds, clean them and dry them to a water content of 12%, then crush them to obtain camellia seed kernels, and screen the shells in the camellia seeds to make the camellia seeds The shell content is ≤2%, and the camellia seed kernels are dried to a water content of 6%. The camellia seed drying is divided into the first drying cycle and the second drying cycle: the first drying temperature is 60°C, The drying time is 40mi; the second drying temperature is 85°C and the drying time is ...

Embodiment 2

[0033] 1) Treatment of camellia oleifera fruit: Screen the recovered camellia oleifera fruit, remove bad fruit, and then place it in a ventilated area to spread out for 8 days. During this period, turn the pile once a day and remove moldy and rotten fruit in time; For 4 days, the camellia seed was cracked naturally and the camellia seed was peeled off, and those that failed to peel off naturally were artificially separated;

[0034] 2) Camellia oleifera seed treatment: sieve the separated camellia oleifera seeds, clean them and dry them to a water content of 9%, then crush them to obtain camellia seed kernels, and screen the shells in the camellia seeds to make the camellia seeds The shell content is ≤2%, and the camellia seed kernels are dried to a water content of 4%. The camellia seed drying is divided into the first drying cycle and the second drying cycle: the first drying temperature is 55°C, The drying time is 50min; the second drying temperature is 80°C and the drying ...

Abstract

The invention discloses a preparation method of squeezed camellia oil. The preparation method comprises the following steps: treating camellia oleifera fruits, treating camellia oleifera seeds, treating camellia oleifera seed kernels, squeezing for the first time, squeezing for the second time and refining. According to the method, manual intervention is started from the camellia oleifera fruit stage to improve the oil yield, a cold and hot alternate squeezing or extraction means is adopted, no chemical additive is used, a pure physical method is adopted, the active ingredients of the camellia oil are effectively reserved, the national tea seed oil squeezing standard is met, and the natural flavor and fruity flavor of the camellia oil are reserved; the method is simple in process, low in cost, sufficient in oil extraction and high in oil yield. Impurities are separated through the acidic white alumina powder for the oil, so that the oil color is clear, and the attractiveness of the oil quality is improved.

Description

technical field [0001] The invention belongs to the technical field of camellia oil, in particular to a preparation method of pressed camellia oil. Background technique [0002] Camellia oil is a unique oil tree species in China. Its fruit can be used to extract important natural green organic health-care edible oil. Because of its golden or light yellow color, tea oil is pure in quality, fragrant in smell and does not contain harmful substances such as cholesterol and aflatoxin. It is widely spread that tea oil contains specific physiologically active substances tea polyphenols and camellia glycosides, which can effectively improve cardiovascular and cerebrovascular diseases, lower cholesterol and fasting blood sugar, inhibit the rise of triglycerides, and have obvious effects on inhibiting cancer cells. Effect. [0003] Camellia oil, also known as wild camellia oil, tea seed oil, camellia oil, is obtained from the seeds of the camellia family (kamellia) Camellia oleifera ...
