Fresh food preservation plan
After dinner, plastic food boxes, microwave bowls, cling film, storage bags, everything that can be saved to the food guys unveiled.
Yes, for the health of the family, the rest of the food can be properly preserved.
For a long time, we have thought that the plastic products used in food packaging and storage, including disposable convenience bags, food packaging bags and reusable plastic containers, are considered safe and harmless.
But in fact, the advice from the experts is: you must carefully understand the composition of the product and master the correct storage method to ensure that there is no threat to your health (healthy food).
銆€銆€鈼?First one: How can I find a digital password on the box to make a good choice?
A simple and feasible method is to follow the instructions from the manufacturer, which can usually be found in the description section of the original packaging of the product.
If you can’t find the relevant content on the outer packaging, you must think twice before buying.
銆€銆€If you have the habit of reading the product manual, you will find a lot of useful information in the text at the bottom of the food box.
A triangular number symbol appears on the bottom of most food boxes.
The entire pattern may also include arrows or other numbers that are used to distinguish the product material category.
When buying a food box, the following numbers deserve our special attention: Number 3: means: This number represents PVC.
This material is relatively hard-grained and is often used in the manufacture of food boxes, water pipes and building materials for a wide range of applications in everyday life.
銆€銆€Directions for use: In general, food boxes made from this material are only suitable for storing dry, low-moisture foods such as rice and pasta.
PVC is not resistant to high temperature, so be sure to transfer the food to a food container suitable for microwave use before heating the food.
銆€銆€Number 6: means: This is the sign of polystyrene.
This material is sometimes foamy and is used primarily for making disposable lunch boxes, cups and cutlery.
銆€銆€Directions for use: Polystyrene has the lowest melting point of all types of food packaging materials, so although it can be used to hold warm foods, do not use a food box that uses this material to heat directly.
銆€銆€Number 7: means: This number represents a material other than PVC and polystyrene or a composite material of various plastic materials.
If the raw material of the food box is polycarbonate (including BPA), this number will appear on the product.
銆€銆€Usage Guide: Standard food box materials are various, their heat resistance and maintenance methods are also different, be sure to read the product description carefully before use, strictly in accordance with the manufacturer’s instructions.
銆€銆€鈼廈asic 2: A comprehensive understanding of the use of the lunch box to update the container in a timely manner – if you find that the food box in your home is deformed, worn, infiltrated with oil (oil food) dirt or has been difficult to wash after a long time, you should take the initiative and let them be laid off as soon as possible.
Dish detergents, detergents and scouring pads can cause wear and even corrosion on the food box.
If there is blistering on the surface of the food box, it means that the damage has been caused for a long time.
Excessively, if the surface is stained by infiltration into the vegetable juice, it means that the chemical components in the food box are highly likely to penetrate into the food in the container during the heating process.
Therefore, experts pointed out that it is necessary to eliminate the aging and damaged food containers in time.
銆€銆€Heating without boiling – for the use of microwave ovens, the difference between heating and cooking seems to be only one line difference.
But this difference is crucial to the safety of plastic food boxes.
Even microwave-specific lunch boxes cannot withstand the high temperature processing.
First, the food is heated to 60 掳 C.
This temperature maintains an appropriate safety distance from the boiling point.
Some materials, such as polycarbonate, begin to soften and melt at around 135 掳 C and therefore cannot be used for food heating.
Even other plastic food containers should avoid such high temperatures.
The secret of safety is to dispose of the food in a microwave-specific container of glass or ceramic material before heating, especially if you plan to use the oven to cook new alternatives using fresh materials, or to heat the long-lasting leftovers at high temperatures.time.
銆€銆€Special bag – When there is no food bag at hand, how about looking for an ordinary plastic bag instead?
Don’t forget, the US Food and Drug Administration only approved several types of specially treated plastic containers that can be used to hold food.
Therefore, even if you are in a hurry and are in a hurry, you can’t just grab a few bottles and cans and put the things you eat inside.
Even if the instructions indicate that the product is harmless to the human body, as long as it is not food-specific, it must not be used to take into account the health of itself and its family.
Expert Tip: To preserve food, be sure to buy food-specific plastic lunch boxes; foods that need to be fresh must be packaged in food-specific storage bags. You must not use stores, supermarkets or even garbage bags for saving or saving time.銆€銆€Clean and square – a basin of hot water, a few drops of detergent, plus a soft scouring pad to clean all the dishes.
It is not necessary to use a strong alkaline cleaner like a decontamination powder to remove oil residue from food.
When using tableware, place the plastic tableware on the top layer.
Before using a new food container, be sure to wash it thoroughly and thoroughly mix the dirt left in the production process into the food.
銆€銆€Each of the directors – self-adhesive food bags and food wrap is the best choice for packaging food.
In order to increase the elasticity of the product, part of the wrap film is made of PVC.
If you are concerned about the adverse effects of PVC on the human body, you can choose a product that excludes plasticizers.
Do not use ordinary plastic containers to heat in the oven.
When using a microwave to heat meals, be sure to place the food in a glass or ceramic dish for the microwave oven.
If necessary, it is best to stick a layer of plastic wrap on the dishes, but do not let them touch the surface of the food.
