The hazards of stainless steel insulated lunch boxes

I believe that lunch boxes are a type of utensil that many people use frequently, especially those who bring their own lunch to work, who come into contact with lunch boxes almost every day. Whenever the temperature turns cold, people often use lunch boxes with insulation function to keep the food warm. Stainless steel insulated lunch boxes are more common on the market. This type of lunch box is very easy to clean and is the first choice for many people. However, there are still many things that need attention in its use and maintenance.

1. The hazards of stainless steel insulated lunch boxes

1. If salt, soy sauce, hot soup, etc. are stored for a long time, as these foods contain a lot of electrolytes, stainless steel will react electrochemically with these electrolytes like other metals, causing harmful metal elements to precipitate.

2. When washing stainless steel tableware with strong alkaline or strong oxidizing chemicals such as baking soda, bleaching powder, sodium hypochlorite, etc., since these substances are electrolytes, they will react chemically with stainless steel to produce substances harmful to the human body.

3. If you use a container to hold traditional Chinese medicine, since it contains many alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with them, which can render the medicine ineffective or even generate some more toxic compounds.

4. If strong acidic foods (such as melons, fruits, vegetables, soybeans, and potatoes) are stored for a long time, metal elements such as chromium and nickel will dissolve.

2. Warm reminder for using thermal lunch boxes

1. When steaming or cooking food, please remove the cover of the matching lunch box for better heating effect.

2. When steaming eggs, in order to make it easier to peel the eggshell and avoid the eggshell from cracking, before steaming the eggs, use the needle at the bottom of the measuring cup to gently tap the top of the big end of the egg to make a small hole, and then place the big end facing up on the steaming rack.

3. After the food is steamed, leave it in the machine to cool naturally for a while so that it tastes better.

4. Do not leave food in a container for a long time. Food contains a lot of electrolytes, which will cause chemical reactions and produce harmful substances if left in a container for a long time.

5. Never use strong alkaline or strong oxidizing detergents such as baking soda and bleach to wash stainless steel tableware.

6. Do not use stainless steel utensils to cook food or medicine, as high temperatures will accelerate chemical reactions.

3. How long can the vacuum stainless steel insulated lunch box be kept

The general insulation boxes on the market now can keep food warm for two or three hours, but there are also many very good insulation boxes on the market. The better insulation boxes can keep food warm for up to six hours. The insulation effect of a better insulation box is also excellent. This insulation box is also a good product in our lives. How long an insulated lunch box can keep things warm also depends on external factors. Generally, when the weather is cold, the insulation time of the insulated lunch box will be greatly reduced. In cold weather, it can only keep things warm for about four to five hours.
