This is especially true for fruits and vegetables, which tend to spoil very quickly.
If you’ve ever had to toss out a bunch of fresh produce, then you know how much time and effort goes into preserving them.
Food preservation has become a big deal recently.
Department of Agriculture estimates that Americans wasted $165 billion worth of food in 2013.
That’s why some companies are developing new technologies to extend the shelf life of food and prevent it from spoiling.
There are two main methods of food preservation: refrigeration and freezing.
Refrigeration slows down the rate at which bacteria grows, while freezing stops the growth of microorganisms altogether.
Both techniques are effective, but they also come with their own drawbacks
