Professor Dong introduced the material codenamed 1 to a temperature of only 70 degrees Celsius, which is easy to deform after being filled with high temperature liquid or heated. Edible plastic products also have a shelf life! Plastic products are exposed to oil for a long time, and when small molecules are added, they will disperse outwards, which is equivalent to the harmful substances being dissolved out, which is harmful to the body. No. 1 material is a one-time item and cannot be used repeatedly in food! Especially seasonings with oil. Experts recommend not using plastic bottles of oil and vinegar, drink less mineral water and drink boiled water.

For the 2 we use the most is the plastic bag, the qualified plastic bag should be printed with product function information, material information, standard information, production enterprise information. The national regulations for plastic shopping bags must be more than 0.025mm. Food plastic bags should be marked with "food special bags" and "QS logos and numbers". The qualified food packaging bags hold the plastic bags with one hand and shake them with a force to make a crisp sound. Colored plastic bags must not contain food.

 

Color drop experiment

The guest Zhou Chuanyu repeatedly wiped the plastic bag with a cotton swab dipped in cooking oil and found that the cotton swab turned red, indicating that the plastic bag is easily discolored with oil, and can not contain food containing fat, otherwise it will lead to cancer.

 

Use a cotton swab to draw the edible oil, wipe the inside of the red plastic bag with a cotton swab, and after 40-50 wipes, it will fade. The word on the plastic bag of the supermarket will not change after wiping. The red plastic bag smells a lot of odor, which is the color masterbatch added to the process to cover the impurities inside. Most of the off-color pigments are organic dyes and are used in industrial packaging. These organic dyes contain aromatic hydrocarbon organic compounds. Some low molecular weight polyethylenes are not polymerized during plastic polymerization. These low molecular substances are difficult to excrete after entering the human body. Most of them have carcinogenic effects, affecting human liver function and reducing human immunity. .

Marks 3 and 4 are cling film, what is the difference between them? Professor Dong told us that the plastic wrap of Mark 3 cannot be used for high temperature and fat-containing foods, and it will release toxic substances and endanger human health. Professor Dong introduced five mistakes in the use of plastic wrap in our daily life: 1. Packing plastic wrap to lose weight; 2. Wrap the wrap when the hair is dyed; 3. When doing hand care, seal the wrap and then wrap the cling film to heat it. 4. The leftover plate is sealed with plastic wrap; 5. The wrap is wrapped in food and placed in a microwave oven for heating.

It’s not that throwing it is really rubbish!
