no. The reasons are as follows:

1. The ingredients of instant noodle barrel are paper and polystyrene. Heating may not cause paper burning and blackening for a short time, but no matter how long the heating time is, polystyrene will have adverse effects on health.

2. If the heating time is long, besides the impact of polystyrene on health, it will also cause paper burning, which will be more dangerous.

"Three Notices" for instant noodles in bowls:

1. Instant noodles bowls should not be heated in microwave ovens.

the material of the flour barrel contains polystyrene, and if the temperature is too high, it will release chemicals. Professor Jing Yubi from the Organic Synthesis Laboratory of the School of Chemistry and Chemical Engineering of Yang Da University said that the instant noodle barrel mainly contains polystyrene and polyethylene.

2. Do not hold acidic substances such as orange juice and vinegar in the instant noodle bowl.

When polystyrene meets strong acid and alkali, it will decompose substances containing benzene, which can cause cancer and be harmful to human body.

3. After eating instant noodles, don't drink hot water in an instant noodle bowl.

if it is used for many times, the specific chemical structure of the material contained in the noodle bowl will be destroyed, which will release toxic substances. The bowl of instant noodles is disposable, and the water temperature of instant noodles should be as low as 1℃.
