1. Look at the texture

When you buy cooking oil, you can first check whether the oil is transparent. Good quality oil is mostly a clear transparent liquid, while gutter oil contains a large amount of chemical components and has a relatively turbid texture.

2. Smell

Gutter oil can also be identified by its smell. Good quality edible oils will have the aroma of the raw materials, such as soybean oil has a bean aroma, and peanut oil has a peanut aroma. Gutter oil does not have these natural aromas, but has a sour taste. After being stored for a period of time, the sour taste of gutter oil will become more severe.

3. Taste and Burn

When buying cooking oil, you can also identify whether it is gutter oil by tasting it. The one with a pleasant smell is good cooking oil, while the one that tastes sour is gutter oil. You can also put the cooking oil on paper and light it with fire. If there is a popping sound, it means that the oil contains a lot of water and is very likely to be gutter oil. It is not recommended that you buy and eat it.
