Tell your parents! Huaxi doctors: Using these bags to store food can really cause food poisoning

The old-style pickled cabbage of 315 is still fresh in my memory

Last month, food additives were a hot topic again.

He can't even have a meal in peace!

Food safety has always been a matter of great concern to everyone. But in fact, food safety is not only about ingredients and cooking methods, but also about packaging. This is a link that is easily overlooked.

For example, the "plastic containers" most commonly used for takeout have very particular requirements on shelf life and heat resistance.

To learn more about the details, let Dr. Xu Miao from the Clinical Nutrition Department of West China Hospital, Sichuan University explain it to you!

If someone says "plastic" now, the first thing that comes to mind is definitely not something as superficial as plastic bags, but words that have been given new life, such as plastic sisters, plastic friendship, etc.

But "plastic" has more than just a new meaning. It may also have its own shelf life, category characteristics, applicable scenarios, etc. These are the real things that are closely related to food safety!

● For example, mineral water bottles made of PET usually contain catalysts, antioxidants, heat stabilizers and other additives containing heavy metals such as lead, tin and antimony during production. These substances can easily release heavy metal elements at high temperatures and cause harm to the human body.

● For example, plastic water cups that are used at high temperatures for a long time will age prematurely and easily release non-beneficial additives and microplastics.

Plastic, like food, also has a shelf life. For example, the stability period of a mineral water bottle is about 10 months. After this time, it may release harmful substances.

High temperature is a catalyst

Unleashing the hidden dangers of plastic

So how do we avoid it?

In fact, most plastics have classification labels. In principle, plastic containers without any labels cannot come into direct contact with food. Some have applicable scenarios indicated, while others directly display their "identity cards." It is up to everyone to determine the different uses of each type.

5 common scenarios + 7 major plastic categories

Dr. Xu used a picture to make the key points clear.

First look, second recognize, third distinguish

The last step is to combine the actual

Let everyone grasp these knowledge points at one time!

Any safety is relative. As long as plastic products are produced in accordance with national standards, marked with food grade as required and used reasonably, they can be considered safe for our food.

In life, we should pay special attention to these three points, which can effectively reduce the health risks brought by plastic containers:

1. Plastic containers without "ID cards" are best not used;

2. Food grade plastics are preferred;

3. Use according to the usage scenario and do not exceed the scope or conditions. ★

Plastic containers must be selected correctly and used correctly! Therefore, the third point is particularly important. We can give you a few more common problems to analyze and deepen your memory!

ask

Can mineral water bottles be reused?

answer

No, really not any more.

The reuse exceeds the application range of ordinary mineral water bottles (No. 1). In addition, special reminder: it is recommended to use No. 1 and No. 7 for room temperature ice water, and No. 5 or Tritan material is required for hot water.

ask

Can disposable lunch boxes be used to store oily foods?

answer

Not recommended~

Generally speaking, plastics are less oily and less hot, so it is not recommended to use disposable plastic lunch boxes to store oily food, let alone heat it. If you really need to put it in the microwave, only No. 5 can be used; No. 2 and No. 4 can be used to warm room temperature food, and No. 3 and No. 6 should be kept away from food as much as possible.

ask

Can the steamed buns in a plastic bag be put into the microwave?

answer

That’s not possible!

Normally, the plastic bags used to pack buns are made of No. 2 or No. 4 materials, which are not suitable for microwave ovens. At the same time, buns are rich in fat, and the heating temperature in a microwave oven can easily exceed 100°, which exceeds the tolerance temperature of plastic bags, and harmful substances in the bags will migrate into the food. It is recommended to heat the buns in glass or ceramic containers.

Used plastic bags cannot be used to store food

But you can put garbage

Plastic water cups are not safe, so we bring our own glass ones.
