In general, food can be eaten after being put in the insulated bucket for 7 hours, but the following factors should be considered to determine whether it is safe:
1. The freshness of the ingredients: if the ingredients have expired or are not properly stored, they may deteriorate even if they are put in an insulated bucket. At this time, they cannot be eaten.
2. Thermal insulation effect of thermal insulation barrels: different thermal insulation barrels have different thermal insulation effects. If the thermal insulation effect is not good, the food may deteriorate in a short time and cannot be eaten at this time.
3. Ambient temperature: If the ambient temperature is too high, even if it is placed in the insulation barrel, food may deteriorate, so the insulation barrel should be placed in a cool place as far as possible.
To sum up, if the ingredients are fresh, the insulation effect of the insulation barrel is good, and the ambient temperature is appropriate, then the food can be eaten in the insulation barrel for 7 hours. However, in order to ensure food safety, it is recommended to smell whether there is a smell before eating. If there is a smell or any unusual situation is found, it is better not to eat.
