Features of Camellia Seed
Oil tea seeds contain more than 30% oil, which is used for food, hair and medicine. It can be used to make candles and soap and used as a substitute for oil. Camellia seed is another name for camellia oil seed, the fruit of the camellia oil tree. Oil tea tree is the main woody oil tree in China, known as "Oriental tree". Its natural ratio and composition of fatty acids are basically the same as that of olive oil, enjoying the reputation of "Oriental olive oil". Camellia seed oil contains tea polyphenols and camellia glycosides, which are not active substances in olive oil, so camellia oil is called "longevity oil" and "Oriental god oil". Camellia seed oil is rich in VE and tea polyphenols, which can clear free radicals, anti-aging, protect the structure of cell membrane, inhibit the release of histamine from mast cells and reduce the amount of cytokine production, inhibit inflammation or reduce inflammation. Other studies have shown that camellia seed oil has significant effects in delaying atherosclerosis, increasing gastrointestinal absorption function, and promoting endocrine gland hormone secretion. Camellia seeds have the effect of cleaning and removing greasy, so camellia seeds washing powder, shampoo and other products are widely used, because they are non-chemical products, good effect, no side effects and favored by consumers.
Camellia seed is the fruit of the camellia oil tree. Oil tea tree is the main woody oil tree in China, known as "Oriental tree". Camellia seeds are mainly composed of water, crude fat, starch, crude protein, tea seed polysaccharide, polyphenols, flavonoids, saponin and crude fiber, and a small amount of tannin. Among them, tea polyphenols, camellia glycosides and squalene are the characteristic bioactive substances, which have the effects of reducing cholesterol, anti-aging and preventing tumor. Camellia oil, extracted from camellia seeds, is a high-quality edible oil, its unsaturated fatty acid content is more than 90%, and does not contain erucic acid, more durable than other edible oils, not easy to rancidity.
Camellia seed is the raw material of camellia oil. Camellia oil has many benefits for the human body and is beneficial to health. Camellia oil "royal food fruit juice, longevity tea" was named as the royal "royal food oil", which gave camellia oil the special status of "aristocrat in oil", so that camellia oil this treasure was officially shining in the world as "national oil".
Camellia oil is also known as "emperor oil" and "decree oil" in the people because of its royal exclusive and imperial edicts a symbol of dignity.
Modern medicine has also proved that camellia oil itself far exceeds all vegetable oil unsaturated fatty acids, as well as rich in vitamin E, plant sterols, squalene, tea polyphenols, camellia, camellia saponin and other active substances, high nutritional value.
Camellia oil has an average amount of monounsaturated fatty acids (oleic acid) 80%. Oleic acid is called "safe fatty acid" by nutritionists, non-polyester, good digestion, heavy oil diet without "belly" load!
Rich vitamins and dietary fiber with camellia oil, bright color, fragrance, fresh and not greasy, high appearance level, high nutrition, light fat, slim light food full of vitality! We should increase our intake of camellia oil.
Camellia oil is obtained from the seeds, Camellia oleifera grows in the pollution-free subtropical the Nanling Mountain humid climate zone, and does not apply pesticides, fertilizers, etc. during the whole growth process. Longitude, latitude, soil and climate are suitable for high nutrient content. It does not contain harmful substances to the human body such as erucic acid, cholesterol, and aflatoxin. The color is golden or light yellow, the quality is pure, clear and transparent, the aroma is fragrant, and the taste is pure.
How to Grow Camellias from Seed
Let Seeds Ripen: Camellia seed pods typically ripen in early fall but can occur whenever camellias are blooming. Wait until the pods open before harvesting the seeds. One way to do this is to tie a bag of loose cloth (like cheesecloth or the end of a pair of pantyhose) lightly around the pod, so it will catch the seeds when they fall. Or you can pick them up off the ground. Mature camellia seeds should be brown, with a tough shell and an “eye” on one end.
Planting Seeds: To plant camellia seeds, you'll need a light seed-starting mix, or a mixture of perlite and peat moss. Wet the planting mix and squeeze out the excess water. Plant your camellia seeds by placing them on top of the planting mix with the eye facing either down or sideways, and cover lightly with soil. Cover the pots with plastic, and place them in a warm spot with bright indirect light (not full sun). Keep the soil moist but not soggy.
Plant Immediately: Plant camellia seeds soon after harvesting. They shouldn't be allowed to dry out, and some growers like to soak the seeds overnight before planting. If you must store camellia seeds, put them in the fridge in an airtight bag.
Germinating Seeds: (Optional) If you prefer, you can germinate camellia seeds in a plastic bag with a handful of soil, then plant them in pots once they germinate. This allows you to focus only on the seeds that are viable.
Be Patient: Camellia seeds can take from one to several months to sprout, and they often sprout roots before leaves, so it takes even longer to see progress aboveground.
Cut the Root. Camellias grow a long taproot that can be stunted if grown in pots. Once the plant has sprouts aboveground, it's common practice to gently dig up the seedlings and pinch off the tip of this taproot, to encourage the roots to branch out into more of a ball.
Allow to Grow: Camellia seedlings can take 5-7 years to bloom, and they likely will not be exactly like the parent plant. You can shave a year or two off the process by looking around under your camellias for seedlings that have sprouted on their own, and gently transplanting them to pots or into your yard.
Using Camellia Seeds to Process Camellia Oil
Select materials, removal of impurities and dry
Selected when producing camellia seed per year, the oleaginousness of described camellia seed is 28%～30%, removes impurity and mildew and rot camellia seed, and it is 9%～11% that camellia seed is dried to water content.
Fragmentation, obtains camellia seed kernels, dries
Broken camellia seed, obtains camellia seed kernels, in camellia seed kernels containing shell amount≤1%, by camellia seed kernels dry to water content be 5%～6%, bake out temperature is 85 ℃～95 ℃.
Cooling, add fresh cavings or tea-seed, low temperature pressing
Be cooled to room temperature, adding weight is fresh cavings or the tea-seed of camellia seed kernels weight 5%～7%, and after stirring, low temperature pressing obtains pressed oil.
Heating, adds citric acid, adds water, stirs standingly, and removal of impurities dewaters
Pressed oil is heated to 60 ℃～70 ℃, and adding total amount is the citric acid of pressed oil weight 0.2%～0.3%, stirs 15min～17min, adding weight is the water of pressed oil weight 10%～15% again, and water temperature is 60 ℃～70 ℃, stirs 7min～14min, standing 4h～6h, removes impurity and water.
Under vacuum, add gac or diatomite, filter
At 120 ℃～130 ℃, adding weight is gac or the diatomite of pressed oil 4%～5%, under vacuum tightness-0.095MPa～-0.085MPa, while being cooled to 60～70 ℃ after 25min～30min, filters.
Stir, cooling, standing growing the grain, filters
At rotating speed, be to stir under 8～9r/min, be cooled to 1 ℃～3 ℃, standing growing the grain more than 3 days, filters, and obtains Camellia oil.
The processing technology, as the camellia seeds with the oil content of 28-30 percent are adopted as the raw materials, the camellia oil prepared by virtue of the scientific and reasonable process is a non-transgenic product, the inherent flavor, fragrance and nutrient substances of the camellia oil are kept to the maximum, the oil yielding rate and the squeezing efficiency are high, the deodorization and decoloration efficiency are good, the green processing requirements are conformed, and the food safety is guaranteed.
Storage Quality for Camellia Oleifera Seeds
Camellia oleifera seed, commonly known as the oil-seed camellia seed or oil-tea camellia seed, just like oil palm,olive and coconut, is one of the most prominent woody edible oilseeds. has much in common with olive oil in chemical composition drawing great attention from the public, with high amounts of oleic acids (76.1%-83.3%) and linoleic acid (7.0%-11.03%) and was often titled as “Eastern Olive Oil”.
However, it is not easy to store the seeds because of the high total amount of unsaturated fatty acids up to 90% and high temperature and high humidity climate in Camellia oleifera seed producing area, which are tend to lead to the quality degradation during storage. In order to maintain good storage quality, the effects of storage conditions on quality of Camellia oleifera seeds and the reasons for them were explored . Using moisture content of material (7%, 8.5%, 10%, 11.5%, 13%), air relative humidity (50%, 60%, 70, 80%) and storage temperature (4, 15, 20, 25℃) as single factors, the change in oil content, acid value and peroxide value of Camellia oleifera seeds were determined during the 8-months storage.
At the same time, the lipase activity, lipoxygenase activity and the growth of microorganisms, which were highly related to the increases of acid value and peroxide value, were also investigated during storage. The change trend of oil content showed an increase in the beginning and decreased after the peak, indicating that there was a phenomenon of post-ripening observed during the storage. the post-ripening period of stored Camellia oleifera seeds was 3-4 months, which was similar to the post-ripening period of 2-3 months for peanut and was obviously longer than the post-ripening period of 10-20 days for corn. The acid value and peroxide value were increased with the increase of moisture content of material, storage temperature and storage time.
The significantly positive correlation between the lipase activity and the acid value indicated that the increase for acid value of Camellia oleifera seeds during storage was mainly due to the accumulation of free fatty acids produced by hydrolysis of fat resulting from lipase. Within 6-months storage, only a few of molds of Camellia oleifera seeds were observed. However, once microorganisms grew in large quantities with the prolongation of storage time, lipase would be produced to further promote the increase of acid value. In addition, based on the above results, the effects of moisture content of material, air relative humidity, storage temperature and storage time on oil content, acid value and peroxide value were investigated using response surface method. The regression equation predicting quality variation was established and it proposed that suitable air relative humidity and storage temperature can promote the post-ripening of Camellia oleifera seeds during storage.
The comprehensive optimization ranges of Camellia oleifera seed storage parameters, obtained using frequency analysis method from the regression analysis of standardized comprehensive score values, were as follows: air relative humidity of 57.6%-67.4%, temperature of 17.2℃-20.4℃, moisture content of 8.9%-10.4%, storage time of 62.2d-110.3d. Under the optimal conditions, the comprehensive qualities of Camellia oleifera seed oil are good. In order to make the best of post-ripening effect and improve the storage quality, it is suggested that in practical operation, air relative humidity of the storage during post-ripening period should be 1%-2% higher than the storage after the post-ripening stage, and the temperature should be 1℃-2℃ higher. This study can provide support for storage and the subsequent oil processing of Camellia oleifera seeds to improve the oil production rate and guarantee the quality.
