Put a piece of translucent barbecue paper on the baking plate of the barbecue stove. As the barbecue time increases, the barbecue paper gradually becomes burnt. In recent years, in street barbecue shops, some businesses claim to use special paper for "paper barbecue". This new way of barbecue is refreshing, but the reporter found that there are hidden dangers. Experts have warned that "paper barbecue" may release harmful substances.
Raw pulp paper is used for food paper in foreign countries
The experimenter took a piece of barbecue paper from the barbecue shop and tested it. Drop about 90 ℃ hot water on the barbecue paper. The paper is not deformed at all. The hot water can flow on the paper. Then soak the barbecue paper in the same water temperature, after about 5 minutes, the barbecue paper remains intact, the surface is still impermeable, but the material is obviously soft, and it can be torn with light force.
"This kind of barbecue paper is very similar to the paraffin paper used in industry before." The so-called special materials and processes are just a coating of chemical materials on the surface of paper, said an industry person who has been engaged in chemical academic research for a long time. This kind of paper coated with special materials is forbidden to be used in food production in foreign countries. After high temperature baking, the paint on the paper is likely to release harmful chemicals. "Some roast duck shops also use this kind of paper to wrap the roast duck." Some cake shops also use the same paper, the industry source said. In foreign countries, the requirements of food paper are very strict, and the use of whitening agent in the composition of paper is prohibited. The foreign food paper basically uses the original pulp paper.
Question on silicone oil paper for barbecue
What kind of technology does white paper for barbecue use? Does it contain substances harmful to human body? The reporter investigated this.
Some online stores sell this kind of barbecue paper, all products are claimed to be used for barbecue, and the process is to smear silicone oil on both sides of the white paper, so this kind of barbecue paper is also called silicone oil paper. Silicone oil is an additive for food packaging, which is allowed to be used in China. For example, a layer of silicone oil may be applied in some trays to prevent food adhesion. Dong Jinshi, executive vice president and Secretary General of the International Food Packaging Association and food safety expert, said: "although silicone oil can be used for food packaging, it is not allowed to be used in high-temperature cooking industries such as barbecue. Silicone oil is only an additive of food packaging, not a food additive. It is not edible. " Silicone oil is soluble in an oily environment, so chemicals may be released during barbecue. Silicone oil is also known as coating fluid, which contains resin, varnish, etc. The polish oil contains benzene, xylene and other toxic substances, which have a great impact on human health and irritating effect on skin and eyes. Benzene is a volatile toxic substance, and chronic poisoning can occur after long-term low concentration contact, which is manifested by the decrease of white blood cells, platelets and red blood cells in the blood, dizziness, headache, memory decline, insomnia, etc.
