All foods have a shelf life, and edible oil as a food is no exception. Usually, the shelf life of edible oil is about 18 months, so don't buy too much stock at one time, buy it now. If the storage time is too long, beyond the shelf life, mildew may occur, and eating this moldy oil will naturally endanger your health.

Look at the color of soybean oil: because the color of high-quality soybean oil is very bright and shiny, when choosing soybean oil, you need to choose bright and shiny soybean oil, so you can choose high-quality soybean oil. On the contrary, if the color is cloudy, it must be inferior soybean oil, so you must avoid buying this kind of soybean oil, so the first step is to look at the color and buy it right.
Look at the transparency: the transparency of high-quality soybean oil is very high, so if you find that the transparency of soybean oil is very low when you buy it, it means that the quality of this oil is not very good, so avoid buying it.
