In our daily life, we often need to properly handle the food that has not been eaten to prevent its deterioration. When we buy fruit home, sometimes we need to preserve it, especially in the hot summer. If we don't pay attention to it, the fruit has gone bad, which not only wastes money, but also affects our health. In ancient times, people usually put the leftover food in bowls and cold water to prolong the deterioration of food. With the rapid development of science and technology, people have invented refrigerators, plastic films and boxes to realize the function of food preservation. The fresh box can be said to be the most widely used way to keep food. The function of fresh-keeping box is not only reflected in fresh-keeping, but also has many specific functions.
The most important function of the fresh box is to keep fresh. In our daily life, we can make all kinds of food materials, which can be roughly divided into raw and cooked ones. If raw ingredients are mixed with cooked ingredients, once one kind of ingredients deteriorates, other ingredients will soon deteriorate with it. Raw ingredients contain some harmful bacteria, which may be transmitted to the cooked ingredients. At this time, it is necessary to separate raw and cooked food materials and store them in the refrigerator in different categories, so as to avoid cross infection and extend the shelf life of food.
The preservation box can also be put into the microwave oven for heating. Ordinary plastic preservation box can not be put into microwave oven for heating, because when the plastic is heated to a higher temperature, it will produce harmful substances to human body and affect health. What can be put into the microwave oven is a heat-resistant glass preservation box, which is made of high borosilicate glass. We can put the food into the heat-resistant glass fresh-keeping box, and then put the whole fresh-keeping box into the microwave oven for heating, which saves time and is very convenient.
Another function of using the fresh box is to save space. The space of refrigerator is limited. If you throw the items that need heat preservation into the refrigerator, the space of refrigerator will be a great waste. The fresh-keeping box has various shapes, which can be arranged and combined according to different needs of users. According to data, using the fresh-keeping box can save up to 40% of the refrigerator space compared with not using it. In addition, most of the fresh-keeping boxes are transparent. When we look for the items we need, we can see the items in the fresh-keeping boxes directly, so we can save a lot of time by eliminating the trouble of searching one by one.
