2. In general, the unopened salad dressing has a long shelf life, usually about 6 months, while the unopened salad dressing is easy to breed bacteria and can only be stored for 1 month, so it needs to be eaten as soon as possible.

3. If the salad dressing is placed at high temperature for a long time, (high temperature in midsummer, etc. ) or directly exposed to the sun, it is easy to deteriorate. When stored at a temperature below 0 degrees, the oil will be separated again. Before opening, put it in a cool place to avoid low temperature. When stored in the refrigerator, please put it on the shelf behind the sliding door of the refrigerator. Moreover, if it is stored at room temperature after opening, the oil in the salad dressing will be oxidized and lose its original flavor. It is recommended to store it in the refrigerator and try to eat it within one month.
