Can Dry Ice Be Used For Long-term Food Storage?

Dry ice is a popular choice for short-term cold storage of perishable items, but when it comes to long-term food storage, its effectiveness is often questioned. Dry ice, the solid form of carbon dioxide, can keep food frozen at extremely low temperatures, which helps preserve freshness for extended periods. However, its suitability for long-term storage depends on several factors. First, dry ice sublimates, or transitions directly from a solid to a gas, without melting into a liquid—a process that can take several days, but eventually, it will completely evaporate. This means that relying solely on dry ice for prolonged periods without replenishment will not suffice. To optimize long-term food storage using dry ice, consider combining it with other insulation methods. For instance, wrap foods tightly in plastic wrap to prevent freezer burn and place them in an insulated cooler or freezer with a base of regular ice for initial cooling. Then, add dry ice to maintain a consistently cold environment. This approach can prolong food storage while minimizing the need for frequent dry ice replenishment.
