Can "frozen" peanut oil be eaten?

Yesterday, Ms. Huang bought a barrel of peanut oil in a supermarket in the fountain, and took home without Kaifeng. After two days, the oil was frozen. The white flowers in the plastic bucket are the same as lard, which is a bit like the winter honey after solidification. I would like to ask if the peanut oil I bought is fake. Can this kind of oil be eaten?

Riga oil in peanut oil will solidify?

Ms. Huang bought Luhua Peanut Grade 1 peanut oil in the supermarket, and the drum packaging has not yet been opened. Inside the oil, the upper part is golden and clear oily, and the lower part is a close to white turbid state, basically opaque.

Ms. Xiao, Ms. Huang’s friend, said that if you look at this oil, it seems that there is no problem. The date of production, the site, and the date have not expired, and there are no traces of being opened. They do not understand why they “frozen”.

“I’ve seen a news report before that peanut oil mixed with lard would freeze,” Ms. Xiao said. Now the oil is about the same as the news. Is this oil mixed with lard?

Subsequently, Ms. Huang dialed the manufacturer's service phone. On the phone, manufacturers said that solidification is a normal phenomenon and can be eaten with confidence. It is recommended that Ms. Huang put the blended oil under the sun, and the underlying oil will melt.

"Why wouldn't any other brand of peanut oil freeze?" said Ms. Huang, although the manufacturer said it was normal, he still had doubts, but the problem manufacturers did not reply. "I can't figure out why the peanut oil I bought is 'frozen' and I can't start to eat."

Grain and Oil Quality Supervision Station: Normal Phenomenon The grain and oil expert of Guizhou Grain and Oil Products Quality Supervision and Inspection Station explained that peanut oil is a type of oil. Peanut oil has its own intrinsic characteristics compared with other oils such as soybean oil and vegetable oil. One of the obvious characteristics is that It will freeze at low temperatures.

"Oil and grease are a mixture of amorphous and crystalline structures, so they gradually become semi-solid as the temperature drops." According to experts, the type of grease is different, the freezing point is also high and low, and the solidification state presented is also different.

Peanut oil contains 20% of saturated fatty acids. At 10 degrees Celsius, it will produce turbidity and even coagulation. In addition, the solidification of peanut oil is a gradual process, when the temperature drops to the critical point near 10 degrees Celsius, peanut oil will become creamy, like lard.

"Peanut oil solidifies in the cold weather is a normal phenomenon, as long as it encounters high temperatures will melt." Grain and oil experts said that the formation of lard oil in the oil is a normal physical phenomenon, does not affect the taste and nutritional value, the public can Eat with confidence.

The news tracking of peanut oil also needs to keep the warm peanut oil solid in a cold environment. In this way, it cannot be conveniently poured out of the oil drum, which will cause some trouble for use.

Grain and oil experts suggest that as long as the solidified peanut oil is placed in a slightly higher temperature environment, it will return to its original purity. If you want to speed up the "thaw" of peanut oil, you can put it in an air-conditioned room and shake it while "thaw".

If you do not want to wait until the peanut oil "frozen" and then "thaw", it is best not to put peanut oil in places with low temperatures. In this way, it will be convenient when you want to eat.
