How to identify the authenticity of edible oil? Here are a few practical methods:

First, observe the details of the packaging. The packaging of genuine edible oil usually includes a clear trademark, shelf life, date of manufacture, factory name, factory address and quality standard code. Counterfeit brand oils may have subtle differences in packaging design from genuine products. For example, counterfeit oils may not have the brand logo on the white tab under the red cap.

Secondly, try tearing the label apart. With a gentle tear, the genuine label will not stick to your hands and can be completely removed, while the label of the fake oil may be sticky and difficult to remove completely.

Thirdly, shake the tank to check. When real oil is shaken, no bubbles will be produced, while fake oil will have obvious blisters when shaken due to the added essence and insufficient evaporation of water during processing.

Of course, there are some things you need to pay attention to when purchasing and storing. Make sure container is clean, dry and tightly sealed before use to prevent exposure to air. The storage location should be in a dry and dark place to avoid light and high temperature from accelerating the oxidation of grease. The oil bottle should be kept away from heat sources to reduce the impact of high temperature on the quality of the oil. When purchasing, try to choose small packages to ensure the freshness of edible oil and reduce the risk of oxidative rancidity.
