The easiest way to identify gutter oil

1. Look at the degree of transparency

Usually, when people identify whether edible oil is gutter oil, they can look at its transparency, because good quality plants have multiple layers of transparency. If alkali or wax is added during the production process, the transparency of the oil will decrease. In other words, when the transparency is poor, it is likely to be gutter oil.

2. Look at the sediment

Under normal circumstances, healthy edible oil that can be consumed by humans will not have any sediment, but some edible oils have some sediment at the bottom. These sediments are mostly impurities in the edible oil. In this case, it means that the edible oil you see may be gutter oil, and it is best not to buy or consume it.

3. Smell

You can also smell the edible oil to determine whether it is gutter oil. Each type of edible oil has its own unique aroma. When identifying it, you can take a small amount of edible oil and heat it in a pot. At this time, you must smell it carefully. If it is a natural aroma, it means it is real edible oil. If there is a peculiar smell or a bad smell, it means it is gutter oil.

4. Combustion identification

To identify gutter oil, you can also drop it on a flammable piece of paper and then light it. If it makes a crackling sound during the burning process, it means that it has a high water content and may have chemical ingredients added. It is refined gutter oil. If it does not make an obvious sound when burning, it means that it is a relatively good quality edible oil.

That’s all I have to say about how to identify gutter oil. After learning these simplest methods to identify gutter oil, you can use these methods to identify it when you buy cooking oil to prevent yourself from being deceived by merchants and buying gutter oil that is harmful to your body.
