During the Spring Festival, when family members gather and interact with each other, every household prepares sumptuous dishes, and how to deal with leftovers becomes a problem. Experts remind that there are techniques for storing and consuming leftovers. Do not use the refrigerator as a "safe" and stuff all the leftovers into it. Zheng Wenxia, Director of the Nutrition Department at Shanxi Provincial People's Hospital, stated that there are specific requirements for storing leftover food. You should pack the food while it is still hot and not wait until it has completely cooled down before putting it in the refrigerator. As long as it is not hot to the touch, you should immediately pack it and put it in the refrigerator. Try to divide the food into small boxes according to the amount of "one meal" to avoid nutrient loss and bacterial growth caused by repeated heating of large pieces of food. Pay attention to classification and sealing, seal the food with clean sealed boxes or plastic wrap, separate raw and cooked food, place cooked food on the top and raw food on the bottom to avoid cross contamination and cross contamination. The storage time for different types of food also varies. Zheng Wenxia stated that the nitrite content of green leafy vegetables will rapidly increase during storage, and they are prone to yellowing, softening, and producing odors, which are neither safe nor delicious. It is recommended to eat them as a meal; Root vegetables and soy products, although more stable than leafy vegetables, still need to be sealed and consumed as soon as possible. Generally, they can be stored for 1-2 days in refrigeration; Meat and egg leftovers can be stored for 1-2 days when refrigerated, and can be stored for about a month when packaged and frozen; Seafood has a high protein content and a fast bacterial growth rate. The longer it is stored, the higher the risk of spoilage. It is recommended to eat it as a meal. Experts remind that before consuming leftovers, they must be thoroughly heated, not just the surface. It is necessary to ensure that the center temperature of the food reaches 75 ℃ or above, or boil it for another 3 minutes to kill bacteria. Before heating, check the condition of the food. If there is a sour or rancid taste, or if it feels sticky to the touch, it is best to throw it away directly. It is recommended to heat leftovers only once, as repeated heating can damage their nutrition and make them more prone to spoilage. Finally, it is recommended that everyone prepare meals as needed during the Spring Festival and try to avoid leftovers as much as possible
