How to prevent peanut oil from deteriorating
Peanut oils are easily oxidized. The longer it keeps, the easier it is to be lost.Especially bulk self -squeezing peanut oil.
1. Storage container
When you have more oil, you can choose a ceramic cylinder to minimize the caliber of the container; when the oil is less, you can use the discountable dark glass bottle.After the oil is filled, the bottle mouth should be sealed to isolate the oil from the air to prevent the oxidation of the edible oil from deteriorating.Do not use metal or plastic bottles (barrels) to make consumption oil, because metal molecules and plasticizers in plastic will accelerate the acidity and deterioration of the acid eclipse, resulting in excessive standards.If it is a barrel oil in the supermarket, it is recommended to tighten the lid after use.
2. Storage location
The stored container should be placed in a place where it is cool, avoiding light, drying, and low temperature.Because ultraviolet and infrared rays in the sun can promote the formation of oil oxidation and accelerate the formation of harmful substances.The oil -storage container should be reduced as much as possible with air and sunlight.
3. Storage temperature
Storage of peanut oil should prevent high temperature.The storage temperature is the best at 10 ° C-15 ° C. Generally, it should not exceed 25 ° C. In summer, it should not be stored. Fresh peanut oil should be purchased as much as possible to eat fresh oil frequently.Pay attention not to mix water in the oil, otherwise it will easily emulsify the oil and turbidity.You can also add hot oil to the oil at a ratio of 40: 1 to play a role in absorbing water.
4. Keep sealing
The sealing container can avoid the infiltration of air, moisture and other substances, and avoid the oxidation of the oil and stink.
5. Prevent oxidation
Prevent the oxidation of peanut oil.When eating more oil for a while, you can use a little antioxidant such as peppercorns, fennel, cinnamon, clove, vitamin C and other antioxidants to add a little oil to delay or prevent the oxidation of edible oil from deteriorating.
6. Avoid new oil mixed with old oil
The old oil used, especially fried, do not mix with new oil. After high temperature cooking, the oil will produce oxidation. If some oxidized old oil is mixed with new oil, it will accelerate the deterioration of the new oil.
How long is the shelf life of peanut oil
Barrel peanut oil shelf life
Most of the barrels or bulk oil purchased by the supermarket are mostly mixed with other oil components. The shelf life is 18 months, and its deterioration will be accelerated after Kaifeng. Therefore, it is better to eat it as soon as possible after Kaifeng.
Self -squeezing peanut oil shelf life
How long does it take for the long time when the peanut oil fried in the countryside will be kept for a long time, and it can be stored for 1 to 2 years.However, some sediments will appear at the bottom of the bulk peanut oil for a long time. In addition, there are some fatty acids formed by fatty acids and glycerin in the oil. When the Hara flavor is produced in the current period, it means that it cannot be eaten.
How to save self -squeezed peanut oil
1. Save the self -squeezed peanut oil should be placed in a place where it is cool, avoiding light, drying, and low temperature.
2. Because the self -squeezed peanut oil does not add any preservatives, consume it as soon as possible after opening.
3. Be sure to install it in a sealed jar to avoid long -term exposure of peanut oil with air for a long time.
4. Self -squeezed peanut oil that you buy is two cans that need to be eaten in the near future.
5. Many people are used to putting peanut oil in a place where the stove is very close. In fact, the high temperature when cooking will cause oil changes, which will speed up the deterioration of oil.Since the self -squeezed loose peanut oil has not been removed and tightly treated, some sediments will appear at the bottom of the bottom after a long time, and there are some fatty acids formed by fatty acids and glycerin in the oil. Once fatty acids are light, oxygen, high temperature, etc.In terms of conditions, chemical reactions will occur to form some columns of oxides.When there is oil and taste, it means that it is not suitable for consumption.
