What to do if peanut oil smells?

Peanut oil needs to be used up within the shelf life after opening. In addition, the storage method of peanut oil is also very important. Try to store it in a cool and dry place. If it is kept in a very humid and stuffy place for a long time, it will deteriorate. If the peanut oil has an odor, try not to eat it at this time, because there will be bacteria in it, which will be unhealthy for your body after eating.

Don't eat it anymore, as peanut oil may go bad and may contain bacteria that can cause discomfort.

The unpleasant smell is caused by the oxidation of peanut oil, which also produces aflatoxin, a highly carcinogenic substance.

If you must keep it, you can do this:

1. Peanut oil will change its taste if left for a long time. If you add a small amount of fried salt to the oil, it can keep its color clear and taste fragrant and will not easily deteriorate.

2. Heat the oil (to 80%), sprinkle in a handful of flour, stir, fry the flour until it turns yellow, turn off the heat, and pour out the oil after the flour has settled.

How to identify the quality of peanut oil:

(1) Color identification

Good quality peanut oil - generally light yellow to brownish yellow.

Low-quality peanut oil is brown to brown in color.

Inferior peanut oil is brownish red to brownish brown in color, and has a dull blue glow when exposed to sunlight.

(2) Transparency identification

Good quality peanut oil--clear and transparent.

Inferior quality peanut oil - slightly turbid with a small amount of suspended matter.

Inferior soybean oil - the oil is turbid.

(3) Identification of moisture content

When conducting sensory identification of the moisture content of peanut oil, the sensory identification method of the moisture content of soybean oil can be used.

Good quality peanut oil - moisture content is below 0.2%.

Inferior quality peanut oil - moisture content is below 0.2%.

(4) Identification of impurities and precipitates

Good quality peanut oil - contains trace sediment,

The impurity content does not exceed 0.2%. When heated to 280°C, the oil color does not darken and a precipitate is precipitated.

Poor quality peanut oil - contains a lot of suspended matter and sediment. When heated to 280°C, the oil turns black and contains a lot of

A precipitate formed.
