How to identify sesame oil

First, look at the color: pure sesame oil is light red or red with yellow. If mixed with other oils, the color will be different. Mixed with rapeseed oil, it will be dark yellow, and mixed with cottonseed oil, it will be black red. For products mixed with other vegetable oils, you can also use the water test method: use chopsticks to dip a drop of sesame oil and drop it on the calm water surface. Pure sesame oil will appear as colorless, transparent, thin, large oil spots, while adulterated sesame oil will appear as thicker and smaller oil spots.

Second, look at the transparency: Generally, good quality sesame oil has good transparency and no turbidity.

Third, check whether there is any sediment: good quality ones have no sediment and suspended matter, and low viscosity.

Fourth, check whether there is any stratification phenomenon: if there is stratification, it is likely to be adulterated mixed oil.

Fifth check: carefully check the trademark, pay attention to the expiration date and the ex-factory date, and be especially vigilant if there is no factory name, address, or quality standard code. Pay special attention to the raw materials or ingredients.

How long is the shelf life of sesame oil

The shelf life of sesame oil is generally eighteen months, and it can be kept in the refrigerator for more than two years. It is best not to store it at room temperature for more than eighteen months. Generally speaking, the shelf life of sesame oil is about 18 months. If it has not been consumed for a long time and has passed the shelf life, it is best not to consume it. Therefore, sesame oil should be used up within one and a half years. Otherwise, the expired sesame oil will have a special pungent smell, the so-called "rancid" smell. This means that the sesame oil has been oxidized and decomposed, and has become toxic and cannot be eaten. Eating a large amount of "rancid" oil can cause poisoning.

Notes on storage of sesame oil

2. Do not bring in other substances to prevent cross-contamination

3. Just store it at room temperature in a cool, dry and ventilated place
