Pressure cooker roasted sweet potatoes without water is dangerous.

Generally, rice cookers have a temperature control system that will automatically cut off the power when the temperature reaches 130 degrees. However, it is recommended not to dry-heat the rice cooker. Long-term high load will affect the service life of the rice cooker. If the rice cooker is dry-heated and has a dry-heat protection device, it will cause the anti-stick layer of the inner pot to fall off. If there is no protection device, the heating plate will be deformed, the inner pot will be burned, and basically the rice cooker can no longer be used.

Taboos of sweet potatoes:

1. Do not eat them raw. The starch in raw sweet potatoes is difficult to digest, so it must be steamed or roasted. It is recommended to use the steaming method instead of frying.

2. Not excessive. Although sweet potatoes can be used as a staple food, if they are used as a staple food for a long time, it may cause malnutrition. Especially for special groups such as those who have just recovered from a serious illness or are pregnant, those with dampness blocking the spleen and stomach, qi stagnation and food accumulation as diagnosed by traditional Chinese medicine should also eat with caution.

3. Don’t eat on an empty stomach. Eating sweet potatoes on an empty stomach is prone to pantothenic acid and heartburn. In addition, sweet potatoes should be eaten while they are hot to make the stomach feel comfortable.

4. Add some pickles to reduce pantothenic acid. Sweet potatoes contain high sugar content. Eating too much will produce a large amount of stomach acid, which can cause acid vomiting or "heartburn". At this time, eating some pickles can alleviate the symptoms.
