Introduction: In daily life, many times, we will take out some free bags from the supermarket, but have you ever thought that some bags of food may not always fit into the bag? The article discusses how to properly use the free plastic bags available in supermarkets to reduce the incidence of cancer. Have you ever behaved in a refrigerator full of fruits and vegetables and plastic bags with different kinds of food? Here's how to use plastic bags to protect you and your family.
Free plastic bags available in supermarkets: how to use them?
Most of the plastic bags commonly found in supermarkets, farmers' markets, wet markets and stalls are made of PE material. PE materials belong to one of the five commonly used plastics, which are generally non-toxic, non-irritating and harmless to the body. However, plastic bags made of PE material are not a panacea, and some foods are not suitable for being placed in plastic bags, which will be explained below.
1. Hot food hot products: the heat resistance of plastic bags is not good, when above 80 degrees Celsius, the plastic will dissolve and decompose, releasing toxic components such as phthalates, and long-term consumption will lead to high blood sugar, high blood lipids and other health problems. Therefore, hot foods such as steamed buns, porridge, and noodles should not be packaged in PE plastic bags.
Expansion: If hot food is packaged in PE plastic bags, due to its poor heat resistance, it is likely to deform, resulting in dangerous substances and potential safety hazards to the human body. Therefore, in daily life, we should be careful not to use plastic bags to fill hot food, so as to reduce the harm to the body.
2. Frozen meat: The sealing performance of PE plastic bags is not good, and meat is easy to be infected by microorganisms, if it is frozen for a long time, the plastic bags are easy to bond with meat, and there will be plastic particles left after melting, and there is a risk of eating.
Expansion: If the frozen meat is packaged in PE plastic bags, it will not only have a certain impact on the quality of the product, but also cause harm to the health of the product. In order to ensure the safety of food, it is recommended to use a plastic bag or other container with good sealing performance to store frozen food.
3. Oil-rich foods: PE plastic bags should not store fat-soluble foods such as oil, vinegar, wine, etc., such as fried chicken, boiled fish, etc., which are likely to melt and crack the plastic bags and produce toxic substances.
Expansion: Long-term storage of high-fat food with PE plastic bags will cause chemical changes between the plastic bags and the food, resulting in toxic substances that harm the human body. In order to ensure the safety of food, we recommend using containers of other materials for storing this type of food.
Which packaged food is suitable?
1. Container selection: When serving soup, oil, vinegar, wine and other foods, you should choose glass containers, ceramic or stainless steel containers, and do not use plastic bags to ensure food safety.
2. Choose a fresh-keeping bag: There are two things to pay attention to when buying:
1) Observation label: Choose a fresh-keeping bag marked with "edible grade polyethylene material" to ensure that the materials connected to the food meet the hygienic requirements.
2) Look at the style: try to choose a food bag with sealant, which can play a better sealing role, prevent leakage, and help preserve the freshness of food.
Extended: Choose the right reservoir to store a variety of foods, which can not only extend the shelf life of food, but also preserve the flavor and nutritional value of food. It is also important to choose the right bag according to the type of food and the storage requirements.
What to consider when eating fresh-keeping bags.
When choosing a fresh-keeping bag, be sure to read the instructions carefully and determine the following:
1. Applicable temperature range: mainly to grasp the heat resistance and cold resistance of the product, and ensure that its use is within the safety limit.
2. Food contact: check the contact between food and food.
3. Reuse: It is necessary to know whether the fresh-keeping box can be reused and whether there is a time to use it.
4. Special food: When eating high-fat food, choose plastic bags with oil-proof agents to avoid food contamination due to food melting and rupture.
Conclusion: The rational use of available plastic bags in supermarkets and the selection of suitable fresh-keeping bags are the key to ensure food safety and health. Do not store food that is not suitable for plastic bag packaging, and choose suitable packaging and plastic bags to reduce the risk of contamination. Let's be more cautious about food storage and protect our health together.
