It is said that mother-in-law and daughter-in-law will have conflicts when they get along for a long time, but in fact, there will inevitably be friction between mother-in-law and daughter after staying for a long time.
Xiao Liu, who is 32 years old this year, has come to the house to help take care of the baby since she gave birth, and many colleagues envy her.
With the help of my mother, life is indeed easier, but there are all kinds of contradictions.
The kitchen, which had been clean and tidy, began to crowd, and the dining table was always a large pile, not to mention, and various bottles of drinks began to appear in the kitchen.
Coke bottles for millet, Sprite bottles for soybeans, mineral water bottles for vinegar, etc., are called reuse in the name of beauty, and they always don't listen to persuasion.
In fact, some plastic bottles are not reusable, so don't reuse them!
1. Seriously, stop reusing plastic bottles and mineral water bottles!
Many older generations with thrifty habits usually like to wash all kinds of plastic bottles and reuse them to hold vinegar, soy sauce, cooking oil, rice, etc. In fact, these seemingly environmentally friendly reuses may also hide some health risks.
We will have one on the plastic products we use every dayCircular sign of small triangular arrows, respectively, marked7-0The numbers vary from one size to another, representing the specifications of the resin that is used to make the raw material. Most of the raw materials used in plastic products such as mineral water bottles, beverage bottles, and various disposable packaging bags that we come into contact with every day are usedNo. 1 PET material。
This material is chemically stable, lightweight, odorless, and airtight, which can be used in food packaging and is a common beverage packaging material. But these kinds of plastic products are basically allIt cannot be reusedIf it is reused or used to hold other things, or stored in unsuitable conditions, it is easy for plastic bottles to become unsafe and leach harmful substances.
PET plastic bottles may precipitate two harmful substances during use:One isHeavy metal belongs to "copper"In the production process of plastic bottles, a metal catalyst "antimony" will be used, and antimony itself is biotoxic and will enter the human body through the digestive tract, skin, etc., and thendamage to human tissues or organs;
The other is plasticizer, which is added by the merchant in order to increase the strength and durability of PETPlasticizers such as phthalates, this plasticizer may disrupt the regulation of endocrine in the human body,Increased risk of cancer.
In particular, the following common foods should never be stored in plastic bottles, which are very harmful.
Cooking oil:It has strong solubility and can dissolve mineral water bottlesPhethalatesand other harmful substances, if these harmful substances are ingested for a long time, they may endanger human health;
Condiments such as soy sauce:This kind of condiment itself contains acidic substances, salt and other ingredients, and using mineral water bottles to fill condiments such as soy sauce may accelerate the deformation of plastic bottles and even release harmful substances into food.
Hot water:Mineral water bottles inIn a hot environmentIt releases harmful substances, so don't use it to fill hot water, in addition, many people are used to putting cooking oilPlace the plastic bottle next to the cooktop, which is also dangerous.
Carbonated drinks:Lemon juice, carbonated drinks and other acidic substances, willAccelerate the degradation of plastics, which in turn releases harmful substances, so it is not recommended to use mineral water bottles for carbonated drinks.
Seeing this, many people will ask,Aren't many condiments and edible oils in supermarkets also packed in plastic bottles, so why are they not risky?
It is true that many condiments and edible oils sold in supermarkets are also packed in plastic containers, but these containers are for themTailor-made。 These containers are designed and manufactured using food simulants with similar substances to carry out migration experiments to ensure thisSecurity.
However, if the plastic bottle filled with water is used to hold condiments such as soy sauce and vinegar, it is not possible to conduct migration experiments on its own to ensure safety.
Second, disposable plastic lunch boxes can not be heated at will, look for this mark
Plastic products have now become a very common thing in life, many office workers will have a bit of a take-out habit, take-out will be used to being heated in the microwave when it is cold, but most of the take-out packaging is now plastic lunch boxes, and heating is also risky.
There are seven categories of plastic products, which are PETE, HDPE, PVC, LDPE, PP, PS and OTHER, while disposable boxes are mainly made ofPS（polystyreneandPP（polypropyleneMade of two materials.
PSof the heat resistance is very poor,If it exceeds 75 degrees, it will be deformed, and it cannot be heated directly in the microwave.When polystyrene is produced, carcinogens such as styrene monomers and styrene-formed oligomers may be formed, and these carcinogens can migrate into food when exposed to heat, increasing health risks to the human body with food ingestion.
PP material, also called"Plastic 5", which is made of 7 plasticsThe only oneA material that can be heated in the microwave, heat resistance up to 140 °C, heating is not easy to decompose, butIt is not recommended to heat foods that are high in oil and sugarBecause the temperature of these foods can be as high as 150°C when heated, it has exceeded the upper limit of what polypropylene can bear.
Third, the safe use of plastic products, pay attention to these 4 details
Plastic products have a wide range of applications in our lives, and many of the various beverages and daily necessities are contained in plastic bottles. However, improper use of plastic products may pose health risks, and it is recommended to learn to use plastic products safely.
1. Look for the identification of plastic products
Common plastic products include polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP) and so on. Polyethylene (PE) is a relatively safe material, with stable chemical properties at room temperature, and is mostly used in food packaging bags, while polyvinyl chloride (PVC) is generally not suitable for food packaging due to contact with high temperature or the possibility that some substances may release harmful substances.
2. Pay attention to avoid high temperature environments
Plastic products generally pay attention to avoid high temperature environment,Do not use it to hold hot drinks, so as not to precipitate harmful substances, some plastic materials even canIn the microwave, it should not be used for too long。
3, Accurate Filling Goods
Different plastic products are used for different purposes, so they must be used strictly according to their purpose to avoid health hazards. Like whatPlastic wrap is not recommended for high-fat foodsbecause the oil may precipitate the plasticizer in the plastic wrap;Plastic products do not need to be used to put strong acidic and alkaline foodsOtherwise, it is easy to have a chemical reaction and precipitate harmful substances.
4. Do not use it for a long time
Plastic products should be avoided for long-term use, especially when designing disposable plastic tableware, consider using it only once, long-term use, not only may breed bacteria, but also precipitate harmful substances, endangering human health.
Plastic bottles can be seen everywhere in our lives, eating, drinking, using, playing, etc. can be filled with plastic bottles, but it is necessary to avoid indiscriminate use of plastic bottles, especially imported food, condiments, etc., so as not to bring health risks.
