The volume to weight ratio of one liter of edible oil is 1.91 ~ 1.93kg/L. Generally, the density of edible oil is about 1.92KG/ L.

Let's look at the densities of the following oils:

1. The density of peanut oil is 1.914 ~ 1.917kg/L.

2. the density of soybean oil is 1.9151 ~ 1.9375 kg/L ..

3. the density of corn oil is 1.917～1.925kg/L/L ..

4. Generally, the density of edible vegetable oil should be 1.91 ~ 1.93kg/L..

Storage method:

1. Store in the dark

Light will promote the production of free radicals in edible oil, which will speed up the oxidation of oil, so edible oil should be stored in the cupboard in the dark.

2. Keep away from the stove

We are used to putting cooking oil directly next to the stove, which is convenient to use, but the temperature will accelerate the oxidation of oil. Generally speaking, the oxidation reaction speed will increase by about 1 times with the temperature rising by 11℃, so cooking oil should be kept away from the stove.

3. Avoid metal containers

Many families like to pack large barrels of oil into metal cans, but metal ions are the catalysts for oxidative rancidity of vegetable oils.

metal ions can accelerate the decomposition of hydroperoxide and promote the activation of oxygen into singlet oxygen and free radicals. Therefore, it is advisable to choose glass bottles for sub-packaging, preferably brown bottles (which can avoid light).

4. Sealed storage

Grease will automatically oxidize with oxygen, so edible oil should be sealed and stored, and the cover should be tightened, so the less contact with air, the better.

5. Buy a small bucket and change it frequently

The longer the cooking oil is left with the lid open, the more likely it will go bad, so try to buy small packages of cooking oil and change it frequently.

if you have bought a vat of oil, you can pour the oil into the oil control pot according to the consumption for one week, then seal the vat of oil with adhesive tape and put it in a cool and dark place. (It's best to eat it within 3 months after opening)

People's Daily Online-I never expected that cooking oil is "sentimental", so you should pay attention to the storage method.
