What oil recovery technologies are there in society?
Edible oil can be made by pressing (physical) and leaching (chemical). So, what's the difference between pressing oil and pressing oil?
Press oil:
The processing technology is "physical pressing method". The production process of physical pressing requires that the raw materials are carefully selected, and the oil is crushed, cooked, fried and extruded after removing impurities and stones, so that the oil is separated from the oil, and fried seeds are added in the mechanical pressing process, and then it is made by high-tech filtration and purification technology.
Physical pressing method can fully maintain the original flavor of raw materials, retain various nutrients, complete color, fragrance and taste, and do not contain any additives, solvent residues and soap base content. It is a green and pollution-free extraction method combining modern technology with traditional technology.
Drain oil:
The processing technology is "chemical leaching method". Chemical leaching method is an oil-making method which applies the principle of chemical extraction, selects an organic solvent that can dissolve oil, and makes the oil in the oil be extracted by contacting with the oil (soaking or spraying).
Leaching method has the advantages of low residual oil (high oil yield) and low labor intensity, but the leached crude oil can only be eaten after chemical treatment such as dewaxing, degumming, dehydration, deodorization, deacidification and decoloration. Therefore, after many chemical treatments, not only some natural components in the oil are destroyed, but also chemical solvents may remain.

Prospect and health care effect:
Camellia seed oil, known as "Oriental olive oil" and "gold in oil", is refined from camellia seeds, with light yellow color and clear and transparent smell, and is a good edible oil. Because of its excellent quality and unique flavor, it is very popular. In recent years, foreign countries have found that the fatty acid composition of tea seed oil is particularly similar to the preferred edible oil olive oil in developed countries in Europe and America, and even superior to olive oil in many aspects. The content of oleic acid and linoleic acid exceeds 80%, so tea seed oil is paid more and more attention, and it is considered as an oriental oil with important commercial value. Therefore, it is of great significance to strengthen the research on the nutritional components and health care functions of tea seed oil and develop tea seed oil products.
Camellia oil is a unique edible oil in China, which has high nutritional value and health care function. Tea seed oil, also known as camellia oil, tea tree oil and tea oil. It is one of the oldest woody edible vegetable oils in China. China is the country with the widest distribution of Theaceae plants in the world and the largest production base of Camellia oleifera in the world. Mainly concentrated in Zhejiang, Jiangxi, Hunan and Guangxi provinces, with Hunan being the most. In addition, only Southeast Asia, Japan and other countries have a very small distribution.
1. Characteristics of camellia oil
The physical and chemical properties of tea seed oil are very similar to olive oil, but compared with olive oil, the unsaponifiable matter content of tea seed oil is very small, which is relatively easy to be absorbed and digested by human body. In addition, tea seed oil also contains bioactive substances that are not found in olive oil, such as tea saponin, tea saponin and tea polyphenols. Among them, tea saponin has cardiotonic effect, tea saponin has thrombolytic effect, and tea polyphenols have many functions such as lowering cholesterol and preventing tumors.
By comparing the fatty acid composition of tea seed oil with several edible oils, it can be found that the fatty acid composition of tea seed oil is very similar to that of olive oil, mainly composed of unsaturated fatty acids such as oleic acid and linoleic acid, with a total content of about 90%. The content of saturated fatty acids is generally around 10%, which is mainly composed of palmitic acid (7% ~ 9%) and stearic acid (1% ~ 3%).
Compared with other edible oils, the content of monounsaturated fatty acid-oleic acid in tea seed oil is the highest among all vegetable oils, and the content of other saturated fatty acids and polyunsaturated fatty acids is quite small. We know that the high saturated fatty acids in edible oil are easy to cause hyperlipidemia and cardiovascular diseases, and the imbalance of ω-3 and ω-6 in polyunsaturated fatty acids will cause various diseases and sub-health. From this point of view, tea seed oil has its unique composition advantages, which cannot be replaced by other edible oils.
2. The health care function of camellia oil.
