Physical and Chemical Properties | Camellia oil is divided into camellia oil, grade 2 camellia oil and grade l camellia oil according to different grades of color, smell and acidity. |
Introduction | camellia oil is commonly known as camellia seed oil, extracted from camellia seed, mainly produced in southern China. Camellia oil contains a large number of unsaturated fatty acids, oleic acid content of 74% ~ 87%, linoleic acid content of 7% ~ 14%. In addition, camellia oil is also rich in vitamin E, squalene, tea polyphenols and other bioactive substances. As camellia oil fatty acid composition and olive oil is similar, and has anti-tumor, lowering blood pressure, lowering blood fat, scavenging free radicals and other physiological functions, so camellia oil is also known as "Oriental olive oil". According to the description of Shanhaijing, Camellia oleifera has been cultivated in China for more than 2600 years. It takes 2 to 3 years for the oil-tea tree to grow to the fruit, and a tree can only produce 2 or 2 oils. Camellia fruit growth period from flowering to maturity, through the autumn, winter, spring, summer, autumn five season of rain, to absorb natural nutrients, Sun and Moon Essence, high nutritional value, is the "China's food structure reform and development plan" strongly advocated the promotion of edible vegetable oil, is also the International Food and Agriculture Organization's first health care plant edible oil. camellia oil is a high oleic acid type of woody oil, oleic acid content of more than 78%, is the general soybean oil, corn oil, sunflower oil three times, slightly higher than olive oil, in addition to oleic acid, it also contains a certain amount of linolenic acid and linoleic acid, and the ratio of linolenic acid and linoleic acid is 1:2.5, which is very close to the standard of health Oil recommended World Health Organization (WHO) (the ratio of linolenic acid and linoleic acid is 1: within 4). At the same time, camellia oil is also rich in beneficial to the human body like tea polyphenols, squalene, phytosterols, vitamin E, phospholipids and other elements. As early as the 50 s of last century, the international clinical, nutrition office will be high oleic acid type of edible oil recommended for Nutritional Health oil. |
Source | camellia oil, also known as camellia seed oil, tea seed oil, tea oil, etc., is obtained from camellia seed by pressing or extracting, is one of the oldest woody edible vegetable oil in China, the cultivation history of more than 300 years, mainly distributed in the Yangtze River basin and its south of 14 provinces (cities, districts), including Hunan, jiangxi and Guangxi provinces account for 76.2% of the total area of the country. Hainan is also very rich in Camellia oleifera cultivation resources, cultivation and utilization of a long history, but for a long time because of geography Isolation, less investment in scientific research and low degree of industrialization of Camellia oleifera, has not received due attention. camellia oil is rare and precious. In addition to Japan and a few countries in Southeast Asia, camellia oil is distributed sporadically in the world, but it is cultivated in large areas in China. Camellia oil is a treasure given by nature to China. Camellia oil is mainly produced in southern China, especially in Hunan and Jiangxi provinces. |
efficacy and role | tea oil as a medicinal oil collection, tea oil because of its rich in a variety of nutrients, oral, external use has a good effect: A, pregnant women during pregnancy eating tea oil can not only increase breast milk, but also on the normal development of the fetus is very useful. Two, infants and children eat tea oil to make good gas, laxation, fire, digestion, to promote the development of bone and iliac body is very helpful. Three, the elderly edible tea oil can fire, beauty, eyesight, black hair, inhibit aging, chronic pharyngitis and prevention of Human Hypertension, arteriosclerosis, cardiovascular disease has a good effect. 4. Tea oil can resist ultraviolet light, prevent sunburn and wrinkle removal. Yunnan is a famous tea producing area, local women commonly used tea oil for hair, face and wash with tea seed. 5. One milliliter Peach Kernel, ten drops of camellia oil (Ti-tree) and five drops of Lavender oil were mixed and applied to the face, which had significant effect on acne. Because of the role of sterilization and enhance immunity of Camellia. And lavender and anti-inflammatory and shrink the role of the hole. In addition, the chloasma, sunburn, are very effective. 6. The insecticidal effect of tea seed is very good. Can be used as a shampoo and conditioner. Tea oil can antibacterial, antiviral and microbicidal. It can prevent tinea capitis, hair loss, Dandruff and itching. Seven, tea oil can also be directly applied to control mosquito bites, has a good antipruritic effect, thick tea oil can remove warts (Virus). 8. The mixture of tea and eucalyptus can be used to treat common cold and throat Catarrh. Nine, in the traditional Chinese medicine prescription often with tea oil modulation of various ointments, pills. at present, China's tea oil is mainly edible, and has broad prospects in the field of medical, food and cosmetics. |
extraction process | due to the large demand for camellia oil, the extraction process of camellia oil is also developing. Now more mature and widely used extraction methods are mechanical pressing, enzymatic and leaching method. Press method mechanical press method is the most original method to extract camellia oil, which can be divided into low-temperature press and high-temperature press according to the temperature of press cavity. enzymatic method is based on mechanical disruption, using enzymes to destroy the cell wall and lipid complex in the cell, so that more oil is released from the oil cells. According to the existing literature at home and abroad, the enzymatic oil extraction process has been developed into three categories: Aqueous Enzymatic, aqueous phase enzymatic and oil enzymatic cold leaching. The high temperature treatment of the oil was avoided by the three methods, the protein activity was maintained well, and the quality of the obtained camellia oil was significantly better than that of the pressing method. Oil enzymatic hydrolysis cold leaching method/cold pressing method for the oil-tea camellia seeds after enzymatic hydrolysis, the oil was leached by leaching method at room temperature, and the solvent was recovered to get the crude oil; the cold pressing rule requires drying to a lower moisture content, followed by cold pressing to obtain a crude oil. This method can be understood as enzymatic pretreatment followed by leaching or cold pressing. The oil enzyme cold leaching method can improve the quality of crude oil and save the production cost only by simple modification of the original equipment. The oil extraction rate is increased by nearly 20%. However, this method has a relatively large defect, the use of a large amount of enzyme, about (3~8) × 103 units/g camellia seed, mainly because of the enzymatic reaction in solid oil, the efficiency is not high, such as the enzyme dosage is small, the emulsification problem will be more serious. no matter the original tea oil prepared by pressing method or leaching method, it can not be eaten. Raw Tea oil contains a variety of impurities, including raw materials, extraction or leaching process. Some impurities are extremely harmful to the human body. Raw Tea oil needs to be further processed (I. E., refined) to remove impurities to become edible refined oil. A complete process from the original tea oil to the finished tea oil, generally includes degumming, Deacidification, washing, decolorization, deodorization, dewaxing and other six steps. That is to say, pressing and leaching are only the process of preparing the original tea oil, and to make the original tea oil into the finished tea oil, it must be refined by a physical and chemical process. |
