I am providing the following because you might find it beneficial for your own health or interest. But also, some of it can be used to benefit your pets too.
Clay, glass, porcelain and earthenware containers have earth
energy. The best things to store in these sorts of containers are sugar, salt, pepper, pickles, dried noodles (pasta) and nuts. It is said that sugar, salt and pepper should not be exposed to the light either and so they should be stored in opaque containers.
Wood containers, including bamboo containers, allow oxygen flow because they breathe. Tea, breads and cereals can be kept in wood container. Items that can go moldy often store better in wood containers. Obviously, wood containers have a wood
energy.
Metal containers of any kind along with plastic containers should be avoided. According to Chinese Feng Shui, products like cheese along with other living products begin to sweat
inside these sorts of containers because they essentially can't breathe. These sorts of containers are also not good because they absorb the odors of the foods stored within them. In Feng Shui, metal containers have metal
energy while plastic containers have fire
energy.
Many people in the olden days would have cold storages or cellars built into the earth. This area wasn't frozen but it was cool, dark and part of the Earth. In traditional or classical Chinese culture, they also observe a similar thing. They noticed that a storeroom beneath or next to the kitchen was the ideal place for storing vegetables. Of course, there was no heating back then and so then vegetable storage area stayed cool. Additionally, the heat of the day and sun did not affect the vegetables being stored.
Ultimately, the Chinese went on to realize that the vegetables stayed fresh longer if they remained in close contact to the earth from which they came. From this, a tradition was developed in China whereby the vegetables would be placed on the floors of the peasant's storehouses.
In the modern day world, the best place to store vegetables that don't need to be refrigerated would be in a separate and cool walk–in closet or storage room that is away from direct sunlight and usually near the basement so it closer to the earth. Also you want either no windows at all or very few. Additionally you want a location that is not damp. Ceramic flooring and walls is the best choice because it's made using Earth ingredients. The vegetables, in this sort of situation can then just be placed on the floor. Many people find this actually works better than a refrigerator, which is actually quite damp.
If you want to take this a little bit further, according to the teachings of Feng Shui, you should then store dry foods on the racks. Of course, prevent direct sunlight if there are windows.
