Can food be preserved without refrigeration?

Desserts

If I asked my grandmother this question, I'm sure I know what her answer would be. Of course! She would say to me, or do you think refrigerators and freezers have always existed? The number of times I have heard you tell, as a child, that before (in your youth) food had to be bought every day and that in houses it was common to have a "fresquera", a kind of ventilated drawer suspended from the ceiling of the kitchen , so that the food remained airy and fresh as long as possible.

I couldn't help but remember this story when I saw the work of Jihyun Ryou, a Korean designer who proposes to rescue traditional knowledge and shape it with current designs to achieve techniques that allow us to maintain our food in a natural way, dispensing with the maximum of technology, much more expensive.

The designer, using wooden shelves or supports, tries to show that food can be kept for a long time in a natural way. Even as long as if they were in a refrigerator. If its conservation method were to become generalized, it would not be necessary to have large refrigerators, a smaller refrigerator would be enough, with the consequent energy savings that this would entail at the end of the year.

For example, Ryou says that apples emit a lot of ethylene gas, which helps speed up the ripening process of fruits and vegetables in contact with them. If combined with potatoes, apples prevent sprouts from emerging. To achieve this symbiosis, he has designed a beautiful wooden box that allows apples and potatoes to be in contact.

I am sure that the ideas of this Asian designer would excite our grandmothers. The truth is that it seems quite exaggerated to me that today everything, absolutely everything, has an expiration date. Food can go moldy or stale. That is why I am sure that food can be preserved without refrigeration. And you?
