Use low-cost silicone oil with caution

May not be "edible grade"

Whether the consumption of such food baked with silicone oil paper will affect the body, the reporter contacted Chen Binghui, a professor at the School of Chemistry and Chemical Engineering of Xiamen University, to analyze this.

"Silicon oil paper has a three-layer structure, the first layer is a base paper, the second layer is a coating, and the third layer is silicone oil. The first layer of base paper is general paper, which is non-toxic under normal conditions, and the third layer is silicone oil. The composition of silicone oil is cyclic polydimethylsiloxane, which does not cause much harm to the body. "Chen Binghui told reporters that for the second layer of coated paper, plastic is coated on the surface of the paper through a casting machine. Composite materials, and the coating is divided into food grade and industrial grade. For the low-priced products currently on the market, it is likely to choose industrial grade coating paper in order to save costs, then it has an impact on the body.

Silicone oil is not edible

Dong Jinshi, executive vice-chairman and secretary-general of the International Food Packaging Association and a food safety expert, said: "Although silicone oil can be used in food packaging, it is not allowed to be used in high-temperature cooking industries such as barbecue. Silicone oil is only an additive for food packaging. , Not food additives, not edible. "

It is understood that silicone oil is also known as leaching liquid, which contains resin, varnish and so on. Varnishes contain toxic substances such as benzene and xylene. Among them, benzene is a volatile and toxic substance. Chronic poisoning can occur during long-term low-concentration exposure. It is manifested by decreased white blood cells, platelets, and red blood cells in the blood, dizziness, headache, decreased memory, and insomnia.
