Whether sesame oil can be eaten for a long time mainly depends on the storage time and whether sesame oil has deteriorated. If it is left for too long, beyond the shelf life, and the sesame oil has deteriorated, there is odor and sediment, then it is not recommended to eat it again. This may lead to gastrointestinal discomfort, such as abdominal pain and diarrhea. If it is preserved for a long time, but it does not exceed the shelf life and the sesame oil has not deteriorated, then it can continue to be eaten.
