First of all, try to choose a relatively cool morning time to cook, and try to reduce the time when food is placed at room temperature. Secondly, you can choose some foods that can be preserved for a long time, such as fruits and vegetables, to ensure the freshness of food.
In addition, if you plan to bring food to the company, you'd better use an insulated lunch box and try to keep it sealed to prevent food from being polluted by the outside world. At the same time, you can put an onion or garlic in the lunch box to prevent food from going bad.
Finally, it is suggested to heat the food before eating at noon, which can better ensure the safety and taste of the food. If conditions permit, you can try to cook in the morning and bring it to the company, then put the food in the refrigerator and take it out for heating at noon.
