preparation example Construction

[0020] The specific embodiment of the present invention provides a preparation method of original ecological cold-pressed camellia oil, and the preparation method comprises the steps:

[0021] S1. After the mature organic fresh Camellia oleifera fruit is spread out and aired naturally, air-dried until the husk is automatically cracked, and separated to obtain Camellia oleifera seeds with shells; wherein, natural air-drying specifically refers to air-drying under the conditions of no precipitation and a temperature above 0 degrees .

[0022] S2. After the shelled camellia seeds are processed by screening, air separation, magnetic separation and color sorting, impurities and mildewed shelled camellia seeds are removed.

[0023] S3. Wash the remaining shelled Camellia oleifera seeds in S2 with soft water obtained by ion exchange treatment, place and dry naturally.

[0024] S4, drying the Camellia oleifera seeds with shells after natural drying at low temperature in a drying room...

Embodiment 1

[0035] S1. Spread out the mature camellia oleifera fruit to dry naturally and then air-dry until the husk is automatically split, and separate the camellia oleifera seeds with shells.

[0036] S2. After the shelled camellia seeds are processed by screening, wind separation, magnetic separation, color sorting and other processes, the impurities and mildewed camellia seeds mixed in the camellia oleifera seeds are removed, and the good shelled camellia oleifera seeds are retained.

[0037] S3. Wash the camellia oleifera seeds with ion-exchanged soft water and place them to dry naturally.

[0038] S4, drying the camellia oleifera seeds with shells at low temperature, laying the camellia oleifera seeds in the drying room with a thickness of ≤20cm, the temperature of the drying room at 40°C, and reducing the moisture content of the camellia oleifera seeds to 8% to 10% to complete the drying process.

[0039] S5. The camellia oleifera seeds are directly pressed by a cold press and th...

Embodiment 2～5

[0043] Using basically the same method as Example 1, the original cold-pressed camellia oil of Examples 2-5 was prepared. The difference from Example 1 is: drying chamber temperature in step S4, adsorbent type, adsorbent dosage, nitrogen flow rate, adsorption temperature, adsorption time, etc. in step S7, as shown in Table 1.

Abstract

The invention relates to the technical field of preparation methods of edible vegetable oils, and particularly discloses a preparation method of original ecological cold-pressed camellia oil and the camellia oil prepared by the preparation method. According to the preparation method, camellia seeds with shells are directly dried, vapor emitted from camellia seed kernels forms saturated vapor pressure under the wrapping action of the camellia seed shells at a certain drying temperature, and outside air difficultly enters the camellia seed shells, so that oxidization of natural active substances after air exposure is avoided better; in addition, through direct cold pressing of the camellia seeds with the shells, a variety of natural active nutrient substances such as coenzyme Q10 in the camellia seed shells can be dissolved more in the camellia seed oil; when the original ecological cold-pressed camellia oil prepared by the preparation method provided by the invention is used for frying food, nutritional components in the food can be retained better.

Description

technical field [0001] The invention relates to the technical field of edible vegetable oil preparation methods, in particular to a preparation method of original ecological cold-pressed camellia oil and the camellia oil prepared by the method. Background technique [0002] Camellia seed is the fruit of Camellia sinensis. Camellia oleifera seed oil is a high-end woody health oil squeezed from Camellia oleifera seeds, and it is a high-grade edible vegetable oil promoted by the Food and Agriculture Organization of the United Nations. my country is the origin of camellia, and its output ranks first in the world. The unsaturated fatty acids of camellia seed crude oil are higher than that of olive oil, and the content of many active ingredients is also higher than that of olive oil, or not in olive oil. Therefore, camellia oil is a woody edible vegetable oil with high nutritional and health value. It is an ideal edible oil for patients with hypertension, heart disease, atherosc...
