The simplest ways to detect whether it is gutter oil are as follows:

1. Put a peeled garlic clove when cooking, as garlic is the most sensitive to aflatoxin. If the garlic turns red, it is gutter oil, which contains a large amount of aflatoxin. If the cooking oil is good, the garlic will be white.

2. Put the oil in your home in the refrigerator for 2 hours. If white foam appears, it is gutter oil.

Look, smell, freeze, burn

Look: see with eyes, color, clarity, impurities

Smell: Use your nose to smell whether there is any peculiar smell. If there is a peculiar smell, it is caused by the oxidation and rancidity of trans fatty acids.

Freezing: Waste cooking oil contains animal fat, which will partially solidify when placed in the refrigerator at a certain low temperature (except for palm oil, of course).

Burn: Heat, check if there is any peculiar smell, use firm garlic cloves, as garlic is the most sensitive to aflatoxin. If the garlic turns red, it is gutter oil, which contains a large amount of aflatoxin. If the cooking oil is good, the garlic will be white.
