What is silicone? Is it the same as plastic?
The English name for silicone rubber is Silicone rubber, which is a "rubber like" substance made of "silicon". Due to their similar names and ductility, silicone and plastic are often confused, but the main materials of these two are completely different substances.
The structure of silicone gel is quite stable, and the most basic silicone gel structure can remain in a state of 150 degrees Celsius for a long time without changing its physicochemical properties. After heat-resistant treatment, the specific silicone adhesive can not disintegrate (connect) in a short time under the condition of 350 ℃ high temperature, so silicone adhesive is widely used in kitchenware and storage containers, and many baking molds are made of silicone adhesive.
In terms of low temperature, silicone gel can withstand temperatures of -60 degrees without becoming brittle, while our household freezer is about -20 degrees Celsius, making it a good container for freezing food ingredients.
Silicone adhesive has heat-resistant properties due to its structure, but there are hundreds of silicone adhesive products on the market. If the raw material of silicone adhesive products is not 100% silicone adhesive, but other components are added, it may significantly reduce the product's thermal stability.
At present, silicone products are widely used, and due to their heat and frost resistance, unlike plastic products, which have plasticizer problems, current research generally believes that the ingredients of silicone have no definite evidence of harm to the "human body", so they are a good helper for mothers in cooking, such as:
Split packaging for freezing and refrigeration: In addition to being frost resistant, silicone gel has a polymerized form that leaves no pores on the surface. In addition, sealing strips reduce the entry of external air and bacteria into the bag, making it more effective in preserving freshness and maintaining food safety.
Boiling and fattening: Put the ingredients directly into a 100% pure silicone sealed bag, then place them in hot water and heat them in a separate bag until cooked.
In addition, mothers may have issues with packaging, storage, and reheating when making non staple foods. They often use ice cubes to separate and freeze the non staple foods, and the baby needs to take out the microwave when needed. When placed in the ice cube box of the refrigerator for freezing, most of them are directly exposed to the air in the cold room. If the mother is not accustomed to repeatedly thawing, and if unclean hands touch non staple food ice bricks, it may cause pollution problems. Therefore, it is recommended to use sealed preservation bags for cold freezing.
A sealed silicone container is a good helper for making side food. Choose an appropriate size of silicone bag according to the baby's desired portion size, cool the cooked side food slightly, and then put it into a silicone preservation bag for sealing. It can be directly frozen in the freezer, which is convenient and can also ensure the safety of bacterial contamination.
And because silicone has a certain degree of heat resistance, after taking out the amount of non staple food that the baby should eat (it is recommended to eat the whole bag without repeatedly freezing), it can be directly placed in the microwave until it is warm, and can be given to the baby for consumption.
Be careful when choosing silicone fresh-keeping bags, and pay attention to the four major principles
After the epidemic, people have taken the concept of sustainable environmental protection to a higher level, and more people have started to implement plastic reduction and non plastic living.
Silicone products are not petroleum products and can be reused, reducing the use of disposable plastic bags and achieving the goal of environmental protection and plastic reduction. In addition, it is not only used for preserving ingredients and cooking, making non staple foods, etc. The high sealing of silicone bags can also be used for tourism bottled items.
There are many types of silicone products on the market, including thousands of fresh-keeping bags. However, not all silicone fresh-keeping bags have the same benefits and effects. Therefore, when selecting, these principles can be followed:
1. Choose a pure silicone fresh-keeping bag, pay attention to the sealing design, and whether it is a plastic chain clip
Pure silicone has high heat resistance, but not all silicone bags are 100% pure silicone. Some silicone bags have a silicone body, but the sealing area is plastic, which may release plasticizers when placed in hot water, microwaves, etc., which can affect human health. So we need to choose a material that is 100% pure silicone, and the sealing clip chain is also made of silicone, which is safer for our products
2. Choose products made of platinum silicone adhesive
Platinum is the best catalyst, and currently, most food silicone adhesives are made of platinum as the catalyst, which can reduce odors or subsequent dissolution issues. Therefore, it is recommended to choose silicone bags that advertise platinum as the raw material for silicone adhesives.
3. Pay attention to whether the inspection is qualified
Pay attention to whether the inspection is qualified, not only to comply with Taiwan's inspection standards, but also to comply with the inspections of the United States and the European Union, so as to avoid regulatory blind spots and better ensure food safety.
4. Pay attention to convenience and whether there is an award bonus
Silicone fresh-keeping bags not only ensure food safety, but also make us willing to use them because of their convenience. So when selecting, it is recommended to consider whether there are design awards, such as the Red Dot Design Award, GIA Global Innovation Award, etc. The bonuses of these awards also provide a layer of endorsement for convenience. Of course, it's best to try it out in the cabinet to find the best and most suitable silicone fresh-keeping bag.
