Rapeseed oil is golden or brownish yellow. It has a certain stimulating smell, has a certain effect of softening blood vessels, delaying aging, and has a high absorption rate of rapeseed oil.Lets take a look at the encyclopedia of rapeseed oil with Xiaobian.
Rapeseed oil production process
1. Clean
Before cleaning, put the rapeseed in the bamboo basket, step on the side mud (mud) with your feet, and then screen it.Remove the gray and mixed with rapeseed through windmills.Then use thick sieves to remove mixed objects greater than or less than rapeseed.
2, seed speculation
Use a messenger pot (can also be used in two cookers), and you can fill in the grass ash or fine sand in the mezzanine.When it starts to fry, the firepower can be slightly larger. After about 0.5 hours, the rapeseed in the pot has a frying sound, that is, the firepower should be controlled.10 minutes before the rapeseed pan should hold the flames. When the temperature of the rapeseed in the pot reaches 115-120 ° C, and the hand twisted rapeseed is golden yellow, it can be out of the pan.Dollow when frying.
3, grinding
The grinding should be flat, the grinding heart is high, the feeding is uniform, the size of the size is split, and the whole seed is not produced when grinding.When crushing the seeds, we must flush diligent. When the head of the head will start, add about 3 sieve rough bran or about 2 cm long grass heart mixing. The thickness of the pressed blank does not exceed 0.2 cm.After thick bran or grass, you can steam the blank directly.
4. Steamed
The head of the head is steaming for about 2 minutes, the green vapor, and the two blank steam for 25 minutes.When steaming, continue to add water to the pot to supplement the loss.Steaming the waist must not leak air, burn fire and coal evenly.A layer of brown should be added to the bottom, which can protect the bottom and not sticky.At this time, change the steamer water.
5. Bag cake, squeeze
Two -round lap, two -way single circle, scattered cakes, concentratedly squeezed, the cake should be fast, the cake should be stepped on flat.The cake is better.
6. Squeeze
Tomber and fight.Make the cake quickly tighten, and press the oil and press the oil after the oil. After 1 hour, most of the oil is squeezed out.The hitting rod should be tied and the tip is evenly tip.The head road was hit for 3 hours, the oil was 90, and the second way was 4 hours.To prevent the cold wind from blowing, cover with a thermal insulation board or sack.
Rapeseed oil storage
1. Low temperature storage
Rapeseed oil needs to be stored in low temperature environments. The temperature is too high and prone to chemical reactions, which changes rapeseed oil ingredients. Not only is the nutritional component losses serious, but it will also cause acid deficiency reactions.Therefore, when rapeseed oil is not used, it should be far away from the stove and the sun and place it in a cool place.
2. Avoid light preservation
Rapeseed oil for a long time with sunlight will accelerate oxidation. Under the influence of ultraviolet light, it is prone to ozone, which generates bad odors and taste.Affect rapeseed oil quality.Therefore, rapeseed oil should not be installed in a white transparent glass bottle.Plastic oil barrels have a certain degree of transparency, so the barrel oil should also be avoided.In addition, the long -term use of a certain oil container should be cleaned regularly, and the dried water is used for reuse, because the mixing of water will also accelerate hydrolysis and oxidation.
3. Seal preservation
Rapeseed oil is one of the edible oils that are prone to oxidation reactions. If you open rapeseed oil with a large area of ??air, it is prone to losing losses.Therefore, after using rapeseed oil each time, cover the oil barrel lid in time to minimize the oxygen content.
4. Add protective agent
Put an appropriate amount of salt in the rapeseed oil storage tank. Use a small amount of rapeseed oil to fully dissolve the salt. After the salt is not settled, place it in the shade for a while, and then pour the rapeseed oil into the glass bottle and save it.Thats how to extend rapeseed oil.
Which is the best for rapeseed oil and peanut oil
Rapeseed oil and peanut oil are two common edible oils. Which two kinds of vegetable oils are good, there is no absolute saying. When consumers choose, they still have to judge based on the actual situation.In addition to the difference in appearance, it is also different from the nutritional content and content ratio.These two kinds of edible oil have their own benefits.

It is recommended that the elderly eat more rapeseed oil.
Rapeseed oil contains a large amount of α-linolenic acid, and the human bodys digestion and utilization rate of rapeseed oil is relatively high, so it is better for patients with cardiovascular and cerebrovascular.However, rapeseed oil lacks some of the human bodys essential fatty acids, so it is lower than other vegetable oil in nutritional value.Rapeseed oil contains mustard, and mustard acid is not easily absorbed by the human body.
