Halogen lotus root can be stored for 3-5 days in cold storage. After the halogen lotus root is packed in a sealed fresh-keeping bowl, it is refrigerated in the refrigerator. The low temperature can effectively inhibit the reproduction of bacteria. Seasonings with antiseptic effect such as sugar and salt are also added to the halogen lotus root, which delays the deterioration of ingredients to a certain extent. Please pay attention to timely consumption, and it is more reliable to enjoy the best taste and safety within this time range. Exceeding this time will lead to food deterioration or loss of nutritional value, and increase the risk of potential food safety problems.
