If the oven is not used for a period of time, odors and bacteria will breed. Preheating can eliminate odors and sterilize. And preheating can also allow the oven to reach the required temperature before putting the food in the oven.

If you put food directly into the oven for baking without preheating, the food may be heated unevenly and the surface may be burnt, affecting the quality. Baking may also fail, affecting the taste of the food, etc.

It takes about 10 minutes to preheat the oven. If it is not enough, it may not reach the specified temperature. If the oven is preheated and left empty for too long, it may also affect the service life of the oven.
