went to the breakfast shop to take out meals, and we can see that some shops directly put the omelet, toast or hamburger that just came out of the pot into plastic bags, and the hot drinks were also directly put into beverage cups, and then attached with plastic straws; Even for internal use, we can see that the plates served on the table are covered with a plastic bag, and the food is placed directly on the plastic bag, which makes people worry that eating so much plastic every day will make us become plastic people.

not every plastic bag is suitable for holding hot food

let's look at the plastic bag first. There are hundreds of kinds of plastic bags in the market, and those that may be used by breakfast shops to put meals or put them on the plates are mainly Polyethylene (PE) and Polypropylene (PP), among which PE can be divided into High-density polyethylene,HDPE) and Low-density polyethylene (LDPE). Further analysis. 111°C, with acid resistance, alkali resistance, oil resistance, water resistance, gas resistance and other characteristics, the appearance is mostly opaque, and there will be a rustling sound when rubbing.

■LDPE: heat-resistant temperature is about 71? 91°C, with the characteristics of acid resistance, alkali resistance, oil resistance, alcohol resistance, water resistance, etc., the appearance is translucent or opaque, and the heat resistance temperature is low, so it is not suitable for holding hot food.

■PP: the heat-resistant temperature is about 91? 141°C, with acid resistance, alkali resistance, oil resistance, alcohol resistance, boiling and other characteristics, the appearance is more shiny.

from the above information, we can know that the heat-resistant temperature and characteristics of HDPE and PP plastic bags are within the safe range, but we should pay attention to LDPE, because of its low heat-resistant temperature, if it is used to contain hot food or noodle soup, it may indeed cause some substances to dissolve out, and long-term consumption may be harmful to health. However, commercial plastic bags will clearly indicate the material and heat-resistant temperature on the outer packaging. As long as the store pays attention, food safety problems will not occur.

Is there a risk of eating plasticizer in the beverage cups and plastic straws in breakfast shops?

Next, let's look at beverage cups and plastic straws. The most frequently discussed issue is plasticizer, especially the rumor on the Internet that "plastic straws are made of Polyvinyl chloride,PVC), so you will eat the plasticizer in the straws when you drink.

but is this really the case?

In fact, plasticizer is just a synonym, which mainly refers to substances that can make plastics softer and more plastic, such as water, vegetable oil, citric acid and silicone oil. Therefore, many PVC products (such as plastic wrap) must be added with plasticizer in the manufacturing process to make the finished products softer. As for plastic products made of other materials, it is not necessary to add plasticizer at all, and if it is added extra, the products will not be molded. Breakfast drink cups are mainly divided into plastic cups and plastic coated paper cups, both made of PE and PP; Let's take a look at plastic straws. The most common material is PP, so breakfast drink cups and plastic straws naturally don't have to worry too much about plasticizers.

manufacturers should do their best to check the obligation. consumers should still pay close attention when buying.

of course, as an out-of-home eater, it is difficult to clearly understand the material of the plastic bags used by breakfast shop operators, so we can only pay attention to the appearance. If the plastic bags shrink when heated, or have peculiar smell or qualitative change, don't eat them any more.

I'd like to share a short story with you. Someone in the editorial team of "Food Power" once saw a shop assistant pick up a plastic bag and put it into the noodle soup that was still smoking. The plastic bag was deformed and shrunk instantly, and of course no one dared to eat that bag of noodle soup.

In fact, the number of plastic bags consumed by breakfast shops is really huge every day. For the sake of health and environmental protection, everyone should prepare reusable lunch boxes and tableware as much as possible, which can not only contribute to environmental protection, but also make us feel more at ease.
