Why does canola oil have black flocculents

Rapeseed oil. There will be black flocculents, mainly because the degumming is not treated well, that is, phospholipids.

The content is very high, the phospholipids will condense after you heat, and the phospholipids are generally no problem, but its disadvantage is that it will be bitter after 280, which will affect the quality of the oil.

There are impurities in it, strain it and you can eat it.

Because the degumming is not well treated, the phospholipid content is very high, and the phospholipid will condense after heating, and the phospholipid is generally no problem, but its disadvantage is that it will be bitter after 280, which will affect the quality of the oil.

Normal rapeseed oil is golden or brown and transparent or translucent. The black rapeseed oil you are talking about here is not pure rapeseed oil, it is not pure rapeseed oil, which contains a lot of sundries. This color of oil is generally used many times before it happens, it is very unhealthy, and it is best not to eat it.

Because of the material, the rapeseed of rapeseed oil itself is blackened, so it will be blackened.

Hello, please ask about cold-pressed rapeseed oil, and ask why it turns black when it reaches more than 200 degrees, just like car oil.

It is insect poop tea, which is black-brown, granular, and as fine as rapeseed.

Insect poop tea aka name"Dragon Ball Tea"It is the Miao, Yao and other ethnic minorities who live at the junction of Guangxi, Hunan and Guizhou provinces and regions like to drink a special tea. The nutritional value of insect tea is higher than that of ordinary tea, containing 18 to 19 kinds of amino acids, a certain amount of crude protein, crude fat, sugar, tannins, vitamins and other nutrients, and also contains trace elements required by the human body.

When these small black insects eat the branches and leaves piled together, they are left with granular feces smaller than black sesame seeds and some residual stems. Use a sieve to remove the residue and take its insect droppings, which is famous"Dragon Ball"。Put it on the pan and fry dry, then press the honey:

Tea: feces = 1:1:

The ratio of 5 is mixed and then fried, and the insect feces tea is concocted.

When drinking insect feces tea, pour boiling water into a colorless and transparent glass, and then put in more than 10 insect teas. Generally speaking, 500 grams of insect tea can be used for a family of five for more than a year.

At the beginning, I saw the tea grains floating on the surface of the water, and then slowly released a thread of blood hovering in the water, like morning smoke, curling Nana, gracefully undulating, scattered in the water, and then slowly scattered to the bottom of the cup like flying flotsam. The insect tea juice is light bronze, sweet and refreshing, and the aroma is clear and pleasant, which is quite similar to high-grade green tea.

1. Rapeseed oil is black and normal, rapeseed oil is golden and processed, without the lettuce flavor of rapeseed oil, it is prepared for people who can't stand the taste, and the black is original and has a strong fragrance.

2. The quality grade of rapeseed oil is divided into several levels, from the first to the fifth grade, the first-level oil is clear and transparent, and there is no difference between people's serious edible oil, from the second level to the fifth grade, the color is getting darker and darker, the fifth-grade oil is basically black, basically no filtration, the fourth-grade to the second-level, the degree of filtration is not the same, the fifth-grade impurities are the most, long-term consumption, the harm to the body is greater, but the stir-fry is more fragrant, some people love to eat.

3. The absorption rate of rapeseed oil by the human body is very high, up to 99%, and the omega 3 content is high. Therefore, it contains unsaturated fatty acids such as linoleic acid and nutrients such as vitamin E that can be well absorbed by the body. Since the raw material for oil extraction is the seed fruit of plants, it generally contains a certain amount of seed phospholipids, which are very important for the development of blood vessels, nerves, and brains.

Canola oil contains little or no cholesterol, so people who are afraid of cholesterol can eat it with confidence.

This can not be judged from the color of rapeseed oil is good, black rapeseed oil when squeezing oil, after stir-frying and heating, this method has a high oil yield, rich aroma, yellow half fried and half pressed, not fried and directly pressed, this method has low oil output, but the nutritional value is high, or refined, the higher the refining level, the lighter the color, the lower the nutritional value. Our family oil selection pays more attention to nutrition, using the cold-pressed process of Oriati low canola oil, like the fragrance is a little stronger, you can choose to press the color of the 3rd grade is darker, you can also choose to press the first level of this clear and translucent, the color is light yellow, the taste is relatively light, but the nutritional value is high, of which the unsaturated fatty acids are high, unsaturated fatty acids are very helpful to reduce cholesterol and reduce cardiovascular diseases. Like olive oil, rapeseed oil has a very high content of unsaturated fatty acids, which is quite suitable for urban people who now live a clean fat and light life, but rapeseed oil is more accessible than olive oil.

In addition, the quality of these brands of canola oil is very high, and the domestic canola oil is also very good, which is comparable to the imported canola oil.
