Peanut oil has high nutritional value, and it can often be seen during cooking. However, in recent years, whether peanut oil contains aflatoxin has attracted much attention. Aflatoxin is a carcinogen, which poses a potential threat to human health. So can peanut oil machine remove aflatoxin from peanut oil? Let’s take a look at it together.

Peanut is relatively easy to breed aflatoxin. During long-term storage, a large amount of aflatoxin will grow rapidly. Aflatoxin will not be destroyed during peanut pressing. Aflatoxin can exist at high temperature, so the aflatoxin in peanut oil will not be decomposed during cooking. The existence of aflatoxin will cause many kinds of harm to human body, so it is necessary to control the content of aflatoxin in peanut oil.

Aiming at aflatoxin in peanut oil, some removal methods have been proposed. Common methods include physical removal, chemical removal and biotechnology removal. The use of peanut oil press to remove aflatoxin belongs to the category of physical removal. Peanut oil press separates the oil from peanuts by physical pressing, which can theoretically remove some particles carrying aflatoxin together with trace aflatoxin. However, it should be noted that peanut oil press can not completely remove aflatoxin from peanut oil, because aflatoxin sometimes exists in peanut oil in trace or even dissolved state, and the removal effect of peanut oil press is not ideal in these cases.

How to avoid the production of aflatoxin

Although the effect of removing aflatoxin by peanut oil machine is not ideal, oil plants can take some other measures to avoid aflatoxin in oil, so as to produce healthy and nutritious peanut oil.

1, Control the quality of peanut raw materials.
Peanuts should be inspected regularly during storage. If you find that peanuts are moldy, you should handle them in time. Separate inferior peanuts from high-quality peanuts to avoid more moldy peanuts, so as not to contain aflatoxin in peanut oil. Peanut raw materials must be screened before the peanut oil press presses oil. Choose peanuts with uniform particles and fresh mildew-free to ensure the quality of peanut oil from the source. If conditions permit, you can grow your own peanuts, then you can choose pollution-free areas and choose soil rich in nutrients and good air permeability to grow them, so as to obtain high-quality peanut oil.

2, Ensure good storage conditions.
Underground storage and low temperature storage technology can be used to reduce the humidity and temperature of the warehouse and keep the environment dry. Considering the heat generated by the respiration of peanuts during storage, enough heat dissipation space should be reserved when peanuts are stored.
Aspergillus flavus is an aerobic bacterium. Therefore, it is necessary to reduce the oxygen concentration in the warehouse. At the same time, people can choose composite polyethylene film bags with low density, poor crystallinity, good chemical stability and good electrical insulation. Waterproof and breathable, storing peanuts can reduce the production of aflatoxin.
When the water content of peanuts is 10%~15%, Aspergillus flavus can grow rapidly. Therefore, we should pay attention to the moisture of peanuts in the warehouse and keep the moisture of peanuts within 10% to avoid the production of aflatoxin.

3, Ensure the scientific and hygienic production process.
Regular peanut oil production enterprises will take strict hygiene measures and scientific production technology in the production process to ensure the quality and safety of products.

4, The supervision departments shall ensure that the supervision is in place.
Monitoring the quality of edible oil is also an important means to protect consumers’ health. Under the relevant national standards, edible oil products must meet certain safety indicators, including the content of aflatoxin and other harmful substances. Therefore, the supervision of the regulatory authorities is also very important.

The above are the main measures to prevent peanut oil from producing aflatoxin. The problem of aflatoxin in peanut oil needs to be paid enough attention and effective measures should be taken to solve it. Only through all-round management and control can the safety of peanut oil and human health be better guaranteed.
