With the development of science and technology and the improvement of living standards, people's requirements for fresh-keeping technology are becoming more and more stringent, from the general fresh-keeping box to today's vacuum fresh-keeping box progress, shows that people's research on fresh-keeping technology is also becoming more in-depth. So what are the differences between ordinary crisper and vacuum crisper? Here are some examples.
Vacuum crisper
Vacuum storage bag
Ordinary fresh-keeping box is generally made of plastic material, which can only be used for simple storage of food, and it is very easy to cause deformation, and cannot be heated, once heated, toxic substances will be released, and the storage of colored food will cause dyeing, odor and other conditions.
The vacuum crisper is made of special materials, with excellent hardness, anti-fall, can be directly heated, will not release toxic substances, will not be deformed because of the change of use time, will not be stained by food, and can be disinfected.
Ordinary crisper can not keep food fresh, there is no good tightness, easy to cause food nutrient loss, not fresh, and because of poor tightness, easy to cause odor, but also easy to cause bacterial growth, unhealthy and safe.
Vacuum crisper is called vacuum, is to make progress in vacuum preservation, vacuum crisper adopts advanced technology, super tightness, the food preservation time, really achieved freshness, preservation time is 3 to 5 times that of ordinary crisper.
Not all glass transparent material crisper boxes are vacuum crisper boxes, to see.
Vacuum storage also has a time limit, not indefinite storage.
