The most important function of the refrigerator storage box is to keep fresh. In our daily home life, we make a variety of ingredients, which can be roughly divided into raw ingredients and cooked ingredients. If you mix raw ingredients with cooked ingredients, once one of the ingredients deteriorates, other ingredients will quickly deteriorate, and the raw ingredients contain some bacteria that are harmful to the human body, which may spread to the cooked ingredients. At this time, it is necessary to separate raw ingredients from cooked ingredients and store them in the refrigerator in different categories, so as to avoid cross-infection and prolong the shelf life of food.
The most common crisper we use is a plastic crisper. The crisper box made of resin is strong and durable, but one thing is that it is not resistant to high temperatures. The maximum temperature it can withstand is about 120 degrees Celsius, and the minimum temperature is about minus 20 degrees Celsius. But it's more than enough to deal with everyday temperatures.
Ordinary plastic fresh-keeping boxes cannot be put into microwave ovens for heating, because plastics will produce harmful substances and affect health when heated to a relatively high temperature. What can be put into the microwave oven is a heat-resistant glass crisper, which is a crisper made of high borosilicate glass. We can put the food into the heat-resistant glass crisper, and then put the entire crisper into the microwave for heating, which saves time and is very convenient.
Another function of using a crisper is to save space. The refrigerator space is limited. If you casually throw the items that need to be kept warm into the refrigerator, it will undoubtedly be a great waste of refrigerator space. Fresh-keeping boxes have various shapes, which can be arranged and combined according to the different needs of users.
