Rapeseed of what can be extracted from vegetable oil

1) Rapeseed oil degumming: remove phospholipids, mucus, resins, proteins, sugars, trace metals, etc. in **, generally using hydration and acid refining methods.

2) Rapeseed oil deacidification: the free fatty acids, acidic pigments, sulfides, insoluble impurities and trace metals in the oil are removed by food-grade lye neutralization method.

3) Rapeseed oil washing: wash away the soaphorn and water-soluble impurities remaining in the oil during the deacidification process.

4) Rapeseed oil dehydration: Heating and vacuum drying are used to remove the water in the refined oil.

5) Rapeseed oil decolorization: the use of clay, aluminum silicate, activated carbon and other adsorbents to remove various pigments, colloids, oxides, etc. in the oil.

6) Rapeseed oil deodorization: using the principle of vacuum air extraction, it removes low-molecular odor substances, free fatty acids, monoglycerides, glycolipids, sulfides, and thermal decomposition products of pigments in oil.

7) Rapeseed oil dewaxing or degreasing: mainly freezing, crystallization or winterization crystallization, fractionation to remove wax lipids in the oil.

Vegetable oils are usually found in the cytoplasm of plant cells, in organelles called "liposomes".

Oleosomes are the places where oil crop seeds store fat, and are formed by a single layer of phospholipid film encapsulating triesterylglycerol.

The process of oil extraction is to break up the cells and extract the oil from the cells.

Therefore, rapeseed is also extracted from the cytoplasm of seeds, and generally goes through three processes: rapeseed pre-pressing process, leaching workshop process, and refining workshop process to produce degummed rapeseed oil.

1. Before cleaning, put the rapeseed in the bamboo basket, crush the side by side mud (mud block) with your foot, and then screen. Windmills are used to remove ash debris that is lighter than rapeseed. Then use a coarse and fine sieve to remove inclusions larger or smaller than rapeseed.

2. Use a sandwich pot to fry seeds (you can also use two pots to set it up), and the sandwich can be filled with grass ash or fine sand. When you start frying, the heat can be slightly higher, and after about an hour, there is a cracking sound of rapeseed in the pot, that is, the heat should be controlled. 10 minutes before the rapeseed out of the pot to suppress the flame, when the temperature of the rapeseed in the pot reaches 115 120, the hand-twisted rapeseed is golden brown after crushing, you can get out of the pot.

Stir-fry frequently.

3. Grinding and grinding should be flattened, the grinding center should be adjusted, the material should be evenly distributed, the size of the seeds should be ground separately, and the whole seeds should not be produced during grinding. Milling seeds should be diligent to sweep, the first billet will be grooved, add about 3 sieved coarse bran or 2 or about 3 cm long grass heart mix, the thickness of the pressed billet does not exceed centimeters, mixed with the specified coarse bran or grass heart, you can directly steam the billet. 4. Steam the first billet for about 2 minutes, steam the green steam, and steam the second billet for 25 minutes.

When steaming, keep adding water to the pot to make up for the loss. The steam waist should not leak air, and the fire should be evenly added. A layer of brown should be added to the bottom of the retort, which can not only protect the bottom of the retort, but also not stick to the blank.

At this time, change the water in the steamer frequently.

5. Wrap cakes, play double circles on the first squeeze, play single circles on the second road, disperse the cakes, concentrate on squeezing, wrap the cakes quickly, and the cakes should be stepped on tightly. It is better to wrap the cake with loose grass.

6. Squeeze lightly and diligently. Make the cake quickly pressed, after the oil is lightly pressed, pressed frequently, after 1 hour, most of the oil is squeezed out, hit hard, slow beat, increase the pressure. The hitting rod should be flat and straight, and the upper and lower tips should be even.

The first course is played for 3 hours, the oil is 90, the second course is played for 4 hours, and the next morning is pressed. To prevent cold wind, squeeze with a thermal insulation board or sack cover.

The refining of edible oil is a major category of the development of human civilization, the previous standard is relatively backward, the refining of edible oil is required to carry out extraction according to the way of artificial service, and then the vegetable oil in the rapeseed flows out, which is more energy-consuming and its time, and now the technology has developed, we can choose the equipment to immediately squeeze out the rapeseed oil, if you clean up the rapeseed, and then carry out stir-frying, and then put the rapeseed into the equipment to carry out the extraction.

Hamsters can eat some cooked sweet potatoes appropriately, cooked sweet potatoes can give hamsters a strong sense of satiety, and the sugar contained in sweet potatoes is also what hamsters like. It should be noted that hamsters should not be fed too much ripe sweet potatoes, because ripe sweet potatoes have a certain stickiness, so they will stick to the gills of hamsters and make the gills inflamed, and too much feeding will also cause hamsters to have indigestion.

The oil refining pot must be cleaned, after the temperature of the pot is raised, wipe the bottom of the pot and the wall of the pot with ginger, pour in rapeseed oil to remove the components with low boiling point, and the rest is cooked vegetable oil, which can be eaten at any time, and the taste is better than raw oil.

Rapeseed.

Canola oil abbreviation"Vegetable oil", mainly from the seeds of cabbage and cabbage (22%-49% oil, average 40%). It contains 21%-27% protein and about 1% phospholipids. These varieties of rapeseed are produced in China, India, Japan, Pakistan, Sweden.

Poland, Germany, Chile.

France and Canada.

In Europe, rapeseed oil** is a winter-sown cabbage-type rape. In Pakistan and Canada, the main type of vegetable oil is summer-sown cabbage-type rape.

Canola crude oil is yellowish and slightly greenish in color, with an unpleasant smell and spicy taste. The rapeseed oil after alkali refining, decolorization and deodorization is clear and transparent, and the color is light yellow and odorless. There is a phenomenon of flavor recovery during storage, but the flavor is different from the original (crude oil).

A few years ago rapeseed oil was made from cabbage-type rapeseed.

Most of the rape grown is cabbage-type rape. After germplasm cultivation, the erucic acid content of many varieties is less than 3%, and there are few "green flavors" in the past. The fatty acid composition of rapeseed varies greatly depending on the origin, and some rapeseed contains more than 50% oleic acid.

Craft. Rapeseed oil in China is generally dark in color and has a special flavor. The oil starts from roasted seeds, is mechanically pressed to make crude oil, and passes through a centrifuge.

Made by removing oil residue. Typically, these oils are reheated to improve their thermal stability. This type of oil is a Sichuan dish.

It is also suitable for high-temperature frying.

Chinese rapeseed oil was originally made from cranberries.

It was not until the introduction of American rape in the 19th century that the two were hybridized to produce the current (semi-)winter rape variety. Because the genetic combination of this type of rape happens to be close to canola oil.

It has a low erucic acid content.

Canola oil is made from the seeds of rapeseed. Rapeseed oil is what we commonly call vegetable oil, also calledRapeseed oil, coriander oil,BrassicaOil, sesame oil, canola oil, is a kind of edible oil squeezed from rapeseed. It is one of the main edible oils in China, mainly produced in the Yangtze River basin and the southwest and northwest of China, and its output ranks first in the world.

After nearly 10 years of efforts, China has transformed the traditional low-quality canola oil into the best nutritional quality of canola oil in bulk vegetable oils, and by 2010, China's rapeseed double low rate reached more than 90%.

Canola oil consumption guide.

1. Oils and fats have a certain shelf life, and oil that has been left for too long should not be eaten.

2. Because there is some "green smell", it is not suitable for direct use in cold dishes.

3. Repeated use of oil after high temperature heating should be avoided.

4. High-quality rapeseed oil unsaturated fatty acids.

oleic acid. The content is second only to olive oil, with an average content of around 61 percent. Experts believe that due to the strong recommendation of foreign grain merchants, there are many misunderstandings in the consumption of edible oil by urban and rural residents.

In general, choose land with fertile soil for planting, and the temperature and humidity must be well controlled.

In this regard, it is necessary to choose relatively fertile soil for planting, so that good results can be achieved, relatively speaking, it is relatively good.

The planting method of rapeseed is very simple, that is, put the seeds into the soil, make a nest in the soil, put the seeds into the nest, and then try a little fertilizer, and then cover the soil again.

Rapeseed planting method, this should be directly into the production certificate, should be able to be admitted, so this should be able to be implemented, and it is very.

If you want to grow rapeseed, you can ask experienced farmers for advice.

Rapeseed planting methods, I think there are many planting methods, basically you can put it in the soil, and then let him find a suitable temperature, and then you can glue regularly, so that it can grow quickly, and it is relatively easy to survive.

The planting method is to sprinkle rapeseed directly on top of the fluffy soil, and then cover it with a thin layer of soil.

The planting method of rapeseed is very simple, you can tidy up the land wolf and sprinkle it.

Rapeseed oil, commonly known as rapeseed oil, is a vegetable edible oil. Rapeseed oil is mainly a transparent or translucent liquid squeezed from rapeseed seeds, the color is golden or brownish-yellow, and there is a fragrant smell, and the dishes fried with it are not only delicious, but also have high nutritional value.

Canola oil is also called rapeseed oil.

Coriander oil, brassica.

oil, sesame oil, canola oil.

Rapeseed oil, along with soybean oil, sunflower oil, and palm oil, is listed as the world's four largest oils.

Rapeseed oil is one of the main edible oils in China, mainly produced in the Yangtze River Basin.

and southwest, northwest and other regions, its output ranks first in the world.

1. Rapeseed is cleaned, steamed, fried and pressed, and filtered to obtain pressed rapeseed oil, which is obtained by alkali refining, decolorization and deodorization; 2. Rapeseed is cleaned, steamed, fried and pre-pressed, and the pre-pressed cake is then leached, and finally the oil obtained is alkali refined, decolorized, and deodorized to obtain rapeseed salad oil;

Uses of Ancient Canola Oil:

From the perspective of traditional Chinese medicine, rapeseed oil is sweet and spicy, warm, moisturizing and killing insects, dispersing fire, and reducing swelling and poison. Canola oil is rich in vitamin E and can protect hair from damage. If canola oil is used regularly when washing hair, it can promote scalp metabolism and blood circulation, and prevent hair loss.

There are also unsaturated fatty acids in rapeseed oil that have strong moisturizing properties. Finally, rapeseed oil has the effect of moisturizing and killing insects, so using rapeseed oil to wash hair has the benefit of relieving itching and dandruff.

In ancient times, oil was extracted by the oil extraction method, flax can get 40 catties of oil per stone, sulforaphane seeds can get 27 catties of oil per stone, Yuntaizi gets 30 catties per stone, woad and amaranth seeds get 30 catties per stone, 15 catties of seeds, and soybeans get 9 catties. Since then, the oil on the table of Chinese has also become more colorful.

Rapeseed oil. Commonly known as rapeseed oil (hereinafter commonly known as rapeseed oil), it is a transparent or translucent liquid obtained by pressing rapeseed (rapeseed, hereinafter referred to as rapeseed), with golden or brown color. Rapeseed oil is one of the main edible oils in China and the third largest vegetable oil in the world, along with soybean oil, sunflower oil and palm oil.

Together, they are listed as the world's four major oils.

Rapeseed has a high oil content, up to 35 -45, and its main use is to extract oil for consumption.

In addition to direct consumption, vegetable oil is very versatile in industry: it can be used to make margarine.

and other foods, as lubricating oil in the steel casting industry.

Generally, vegetable oil has a wide range of uses in machinery, rubber, chemicals, plastics, paints, textiles, soap making and medicine. The protein content of rapeseed meal is as high as 36%-38%, and its nutritional value is similar to that of soybean meal, which is a good concentrate feed and is widely used in freshwater aquaculture.

In addition, biodiesel has emerged in recent years.

The project has increased the proportion of vegetable oil converted into biodiesel year by year, making it an ideal alternative to petroleum diesel.

1: Cleanse the liver and relieves gallbladder 2: Anti-inflammatory skin care Rapeseed oil has an anti-inflammatory effect.

3 Eye care Rapeseed oil is eye-nourishing, and regular consumption can prevent senile eye disease. 4 Lipid lowering** Rapeseed has a strong effect on promoting lipolysis. People with high blood lipids and obesity can lower their lipids by eating rapeseed oil**.
