The rapeseed oil squeezed by the rural family is very smoky, what is going on?

According to the results of the experiment: the rural family pressesCanola oilThe smoke is large because of the factors of impurities and the use of pots

1.Home-pressed rapeseed oil in rural areas

After harvesting the rapeseed grown in the countryside, it is dried and simply dusted, pulled out of nearby oil and processed into canola oil. The process is very simple. First of all, the rapeseed.

Crush and then start squeezing the oil. Therefore, oil extraction is a kind of ** that contains a lot of impurities. Since this is rapeseed oil pressed by the local soil method, it can be said that the "original ecology" is preserved because these shears are relatively simple,These impurities cannot be removed

After cooking and oilingThe temperature at which smoke begins is called the "smoke point".The higher the smoke point, the less likely the oil is to smoke, and the lower the smoke point of the oil, the easier it is to smoke.

The rapeseed oil pressed in the rural soil is unrefined and therefore contains a lot of impurities, so the smoke point is very low。The level of the edible softening point is closely related to the amount of impurities it contains, and its content can be increased by purification. For example, soybeans and peanuts** typically have a smoke point of around 150-160 degrees and can reach 230 degrees or more when refined.

2.Other reasons for large oil smoke

Another reason is becauseCanola oil ignites more easily than other oils. So ifHeat flammable oil, or if the pot used at home is not an iron pot, then the iron pot itself will produce fine debris, which is also prone to oil smoke。RuralThe oil press is relatively simple, so basicIt can only be simply filtered and does not have purification technology

3.Difference Between Homemade Oil and Refined Oil

Rapeseed oil extracted by soil methods contains impurities. Whereas freshly squeezed oil, it is basically dark, generally opaque, and has a lot of foam. Even when the canola oil is almost consumed, many impurities remain at the bottom of the oil pot.

Since the cooking oil bought in the supermarket is a refined commercial oil, it does not smoke a lot because refining is to remove various impurities from the oil. As a result, such a commercial oil not only has a high appearance value, but also has very little smoke when cooking.

Therefore, due to the fact that the rural home-pressed rapeseed oil is inA lot of impurities will be left during the grinding process, and the iron pot itself。SoThere is a lot of oil smoke.

Because there is no additive to squeeze it out of my own home, it is said to be particularly clean and hygienic.

Because this is to be purified to a certain extent, the requirements are relatively high.

Because after all, it is processed by hand, and this way is healthy.

Because there is no machine processing, there are many disadvantages of manual efficiency.

Rapeseed can be used to press edible oil, rapeseed is harvested in early or mid-May every year, rapeseed is easy to crack and fall to the ground, the maximum allowable emission concentration of oil smoke is mg m3. The edible oil exceeds the maximum allowable emission concentration. The highest was soybean oil, with an average concentration of mg m3, which was a multiple of the maximum allowable emission concentration; The fume concentrations of rapeseed oil and peanut oil were 11 times and 11 times, respectively.

Avoid too much fire, slow fire to make oil, the oil smoke will be smaller.

The traditional rapeseed oil pressing method mostly adopts the hot pressing method, which can improve the oil yield and flavor. When rapeseed is subjected to high temperatures, its structure will undergo some changes, resulting in many suspended impurities in the oil during the pressing process, and many invisible suspended substances are free in the oil. If the filtration equipment is relatively simple, or you may be using traditional salt and caustic soda precipitation methods, these suspended solids cannot be removed.

These finely suspended solids are the culprit.

If you heat the flirtatious oil, or if the pot used in the home is not an iron pot, the iron pot itself will produce fine debris, which is also prone to oil smoke. Rural oil presses are relatively simple, can only be simply filtered, and there is no purification technology. When the canola oil is almost used up, many impurities remain at the bottom of the oil pot.

Since the cooking oil bought in the supermarket is a refined commercial oil, it does not emit a lot of smoke because it is refined to remove various impurities from the oil. This commercial oil not only has a high aesthetic value, but also has a low smoke content when cooked. Because the rapeseed oil extracted by rural families will leave a lot of impurities in the grinding process, the problem of the iron pot itself.

It is a normal phenomenon, if the quality of rapeseed oil is not good, the oil smoke is relatively large, and the self-grown rapeseed oil will have quality problems.

This is very normal, because for the rapeseed oil pressed by the countryside itself, it actually has more impurities, of course, it also has a certain relationship with the pot.

This is a very normal phenomenon, the rapeseed oil pressed by the rural family is easy to smoke very large, but there is no other treatment.

The oil smoke of rapeseed oil is relatively large, which is the specific decision of the rapeseed oil itself, after all, it has not been deeply processed to remove impurities, and the oil smoke will be relatively large. The solution is either to replace rapeseed oil with salad oil, or to buy canola oil with better purity and higher purity, which should be better. Also, you heat a lot of rapeseed oil at one time, turn the lettuce oil into mature rapeseed oil, and then put it in a container, and use the cooked rapeseed oil directly the next time you use it, so that there is not so much oil smoke.

Summary. Hello, kiss, I am very happy to answer for you how to solve the big rapeseed oil smoke, 1Open windows for ventilation, or turn on exhaust fans and range hoods. 2.Spray some air freshener to further remove the smell of oil smoke.

Is the oil smoke of cooked canola oil big.

Hello kiss is very happy to answer for you how to solve the rapeseed oil fume large size preparation, 1Open windows for ventilation, or turn on exhaust fans and range hoods. 2.Spray some air delay gas freshener and take a roll to remove the smell of oil smoke.

Big kiss, if it is their own Kai then squeezed, the smoke with a round taste is greater, and the pressed rapeseed oil also contains water and volatile substances such as fatty acids in the oil, of course, there will be a lot of oil smoke.

What kind of oil has less fumes?

Peanut oil has the least amount of fumes. Peanut oil: light yellow and transparent, bright color, fragrant smell, delicious taste, is a relatively easy to digest edible oil.

Peanut oil contains more than 80% unsaturated fatty acids. In addition, the banquet also contains palmitic acid, stearic acid and arachidic acid and other saturated fatty acids. The fatty acid composition of peanut oil is relatively good, and it is easy for the human body to digest and absorb the wheel.
