The instant noodle paper barrel consists of a barrel body and external stickers, wherein the barrel body consists of food-grade paper cups and polyethylene (PE) films, and the food-grade polyethylene (PE) is the innermost coating of the instant noodle paper cups, which is acid-resistant, alkali-resistant and corrosion-resistant, and the polyethylene below 100 degrees Celsius will not release harmful substances.
Food-grade polyethylene has higher heat resistance than ordinary polyethylene, and it is impossible to produce carcinogens when it changes. It shows that the inner layer of the toilet bowl does not contain fluorescent agent at all; External stickers generally use recycled paper that meets the requirements of printed product information and advertising, and meets the national standards for the use of fluorescent agents.
The bowl of barreled instant noodles is made of polystyrene. In order to prevent deformation after heating, BHT stabilizer is added. However, when high temperature is encountered during brewing, these substances will be dissolved. Japanese scholars have done research reports in this field, pointing out that the dangerous amount of styrene intake per kilogram of body weight per day is 0.00 1 mg, while the dissolved amount of a bowl of instant noodles is 0.0 15 mg, which is almost 60% of the dangerous amount.
Therefore, that bucket of instant noodles is not as harmful as everyone thinks, but try to eat as little as possible!
Crack the rumor of instant noodles
Rumor: there is a layer of wax on the inner layer of the instant noodle cup! Eating instant noodles for a long time will stick to the stomach wall and lead to death!
Truth: Actually, there is no wax in the inner layer of the instant noodle cup.
If you find that the cup is made of foam or thin plastic, then the commonly used material is polystyrene plastic (PS).
If it is a paper instant noodle cup, the inner side will generally be coated with a layer of polyethylene (PE) to increase water resistance, such as the following one.
The polystyrene plastic cup can withstand the high temperature of at least 95℃. Above this temperature, the plastic cup may soften and deform, which will affect the use. However, no so-called "toxic substances" will be released during this softening process. Polystyrene is the "main force" causing white pollution, so the voice of eliminating polystyrene has been very high.
The paper lunch box coated with polyethylene is even more reassuring, because its melting point is about 1 10℃, and there is no way for Lian Gang to boil water.
Even if you really eat wax, it won't stick to the stomach wall. Either digested and absorbed, or excreted directly. Will not cause any adverse consequences to the human body.
Rumor: it takes 32 days for the liver to detoxify and eat a pack of instant noodles! BHT added in oil is toxic and will cause harm to human body.
Truth: There is no evidence to support this statement.
The full name of BHT is "2,6-di-tert-butyl-p-cresol", which is a common antioxidant in oils and fats. If there is no antioxidant in the oil, it will go rancid quickly and be harmful to the health.
At present, FDA and China have strict limit standards for antioxidants like BHT, so it can be said that as long as they are within the limit, they are safe to eat.
