The fresh-keeping film is simple and inexpensive, but it helps a lot in our daily life. But Xiaobian reminds us that not all foods can use the fresh-keeping film. Which foods can't use it?
Some people take the meat, cheese and other food out of the plastic packaging of the fresh-keeping film as soon as they go home, wash the surface layer or slightly cut the surface layer and put it in other 'food grade plastic bags' or containers.
It's best not to let your food touch any plastic film. Use porcelain bowls or stainless steel containers with covers. If possible, when buying meat, try to wrap it in your own paper.
The food is placed in a ceramic bowl without a lid. If the plastic film (plastic film) is attached to the bowl, do not fill it up to avoid touching the food. When packing food with any plastic film (preservative film), it is absolutely not allowed to cook in microwave oven or heat in steamer or electric rice cooker! Even if it is not touched, it is better to remove the plastic film.
We should pay attention to the correct use of preservative film, not to use everything blindly. Some common sense is still needed to understand.
