In order to whiten and increase the freshness of rice noodles, many rice noodle manufacturers will add sodium bicarbonate during the processing. Sodium formaldehyde bisulfate is an industrial bleaching agent, which is not suitable for human consumption. If the human body ingests this substance for a long time, it may cause dizziness, headache, lethargy and fatigue, loss of appetite and decreased vision. In severe cases, it may cause anemia symptoms.

Cause poisoning

The food safety of rice flour is a worrying problem at present. In order to increase profits, many unscrupulous traders often add some unknown food additives or industrial raw materials in the process of making rice noodles. After these things are ingested by the human body, the harm to the body is very great. Light will only cause some discomfort to the consumers, while heavy may cause poisoning and pose a threat to people's life and health. Therefore, it is better to eat less rice noodles.
