Box lunches should not be eaten after being left for 4 hours.

Whether you are traveling or working, fast food lunch boxes have become people’s first choice for lunch. After all, box lunches are very convenient, fast, and very cheap. Many people think that lunch boxes are not just freshly made meals, but just packed in boxes, but in fact, box lunches also have a shelf life.

The hot and high temperature of summer is a period of high incidence of bacterial growth and reproduction. It is best not to continue eating lunches that last more than 4 hours. For your own safety, pay special attention to food hygiene in summer.

Not only boxed lunches, but also unfinished meals cooked at home should be immediately sealed with plastic wrap and placed in the refrigerator for refrigeration. Always make sure the meal is heated through before eating it next time.

How to preserve lunch boxes

You can use insulated bags to pack lunch boxes. You can put a bottle of frozen water in the insulated bag to keep it fresh. Generally speaking, preventing the deterioration of lunch boxes can start from the purchase of lunch boxes. Generally speaking, lunch boxes with separate meals can better maintain the freshness of the ingredients, and different dishes can be packed separately to maintain the original quality of the food.

Many people are accustomed to packing the leftover meals from the night before into lunch boxes for the next day’s lunch. In fact, this method is wrong. Storing food the next night will not only breed bacteria easily, but also produce nitrite, so it is recommended that lunch boxes be made on the same day.

It is best to control the moisture of the prepared meals before putting them into lunch boxes. After installing, be sure to wait until the food has cooled completely before replacing the lid. This can prevent the food from cooling into water droplets when encountering water vapor and dripping back into the lunch box.

The choice of lunch ingredients is also very important. Generally speaking, when choosing ingredients, try to choose eggplants, cucumbers, pumpkins, etc., which have less moisture after cooking and are not easy to spoil.
