Peanut oil is expired and still unopened can be used
Can not be used.
Expired peanut oil can be consumed to supplement the body's nutritional needs. After the expiration date, if some of the peanut oil precipitation or flavor changes, it is best not to eat.
Expired peanut oil can not be consumed and may lead to poisoning, nausea, vomiting, bloating, diarrhea and other symptoms. Some patients will experience skin symptoms. In our life, we should eat more fresh food and closely observe our health condition. Expired peanut oil may break down some toxic substances. Intestinal irritation can occur after eating, which has a great impact on health.
Peanut oil has a long expiration date. When there is precipitation or flavor changes, the nutrients of peanut oil may be reduced and bacteria and microorganisms may multiply. It is best not to eat it to avoid irritation of the digestive system or food poisoning. Peanut oil needs to be discarded immediately after the expiration date when the color and taste change.
When buying peanut oil, please pay attention to the production date. It is best to consume it within the shelf life. It is also important to control the intake of peanut oil. It is best not to exceed 30 grams per day.
Does peanut oil produce aflatoxin when it is expired and unopened
It may also produce aflatoxin.
It is not recommended to consume peanut oil beyond its shelf life. Expired peanut oil may produce aflatoxins, which can easily cause discomfort. Good peanut oil is light yellow in color, transparent, clear in color, aromatic in smell and delicious in taste.
If peanut oil is left for a long time, it may produce small amounts of aflatoxin. Aflatoxins are produced over time. The longer the oil is in contact with air, the higher the likelihood of production. Therefore, peanut oil should not be used for too long. The scary thing about aflatoxin is that it is heat resistant and difficult to remove.
Therefore, when consuming peanut oil, be sure to heat it until light smoke comes out of the sides of the pan, or boil it first until it is slightly hot, adding the proper amount of salt. The iodide in the salt removes some of the toxicity of aflatoxin, and then cook the dish to remove the aflatoxin.
What are the hazards of eating expired peanut oil
1. Poisoning
The oxidative rancidity or oxidative decomposition of the oil produces a large number of toxic epoxy propanal small molecular aldehydes. After eating, it may lead to food poisoning.
2. Stimulation of the gastrointestinal tract
Rancid oil has a strong stimulating effect on the gastrointestinal tract. After eating, nausea, vomiting, abdominal pain and diarrhea and other uncomfortable symptoms. In severe cases, the growth can lead to gastrointestinal bleeding.
3. Hypoxia
The peroxides and other toxic substances produced by the deterioration of grease will convert hemoglobin 2-valent iron into hemoglobin 3-valent iron. Its toxic effect makes hemoglobin lose its oxygen-carrying function, resulting in mucous membrane and skin hypoxia and cyanosis.
4. Respiratory difficulties
The oxides of the rancid substances directly destroy important enzymes in the body's enzyme system, such as succinate oxidase and cytochrome oxidase, interfering with the intracellular tricarboxylic acid cycle and oxidative phosphorylation, hindering intracellular energy metabolism, and generating intracellular asphyxia, leading to acute respiratory and circulatory failure in patients.
