Introduction of Freeze-Dried Food Life and Mountain House Freeze-Dried Food Shelf Life

Introduction of Life of Freeze-Dried Food

Freeze dried food aren’t manufactured by a single company only. This means that the quality and standard of freeze dried food differ depending on which manufacturer produced the product. Some manufacturers have freeze dried food that last for only two years, while there are others, like those at Mountain House 72 Ca., which can last for 30 years.

However, the manufacturer isn’t the only thing that affects the life of freeze-dried food. Its quality before being opened, its exposure to certain elements, and a lot of other things affect their shelf-life. To understand it better, we’ve prepared a short description of the things that affect your freeze dried food’s shelf life.

This might be quite a long read, but it’s definitely interesting, so while you’re at it, why not enjoy a Mountain House Mac and Cheese Canada for a delicious snack while reading.

Oxygen and Moisture Exposure

Exposure to oxygen and moisture greatly deteriorates the shelf life of freeze dried food. Those that aren’t packed tightly, or weren’t vacuumed fully, will not last for months and would probably cause significant diseases when consumed. However, freeze dried food that are processed properly would of course last longer.

Food Quality
Of course, the quality of food that is stored inside a can or pouch greatly contributes to the length of its shelf life. Those which use sub-standard ingredients will definitely last shorter than those that use only the best ingredients. Sub-standard quality of food will probably last around two years, but the quality of its taste would start to deteriorate after six months.

On the other hand, quality food will last for 25 years or longer, while the taste still varies greatly, depending on the manufacturer.

After Opening
These elements only apply to freeze dried food which are packed. Once you open a packed container, there is a huge difference in its life. Since the elements mentioned above are what affects its shelf life when packed, the same elements would affect them in a greater manner once opened. 

To minimize the risk of your food spoiling, you can try packing it back in its original state, meaning, an airtight, cold, and dark environment. However, it is important to note that this does not guarantee that it will bring back its original shelf-life.

Heat and Light Exposure
In the same manner as oxygen exposure, heat and light exposure pose just as much ability to deteriorate your food. Since organisms need light and heat to survive, exposing your food to these elements allow for such organisms to thrive. If your food is prone to fluctuating environmental temperatures, extremes such as 80 degrees or above and just below freezing, you can expect your food to spoil in just a few days or weeks.

This means that freeze dried food loses its nutrients and taste quality if exposed to these elements, rendering them unsafe to consume.

Mountain House Freeze-Dried Food Shelf Life

If you’ve already taken a good grasp of how certain elements affect the shelf life of freeze dried food, then you probably noticed that pretty much all of the elements that affect it is in your hands except for one – the manufacturer.

While it is true that where and how you store your packed food greatly affects its shelf life, it’s also true that the ingredients used and how it’s stored before you purchase it depends greatly on the manufacturer. Which means that even if you give it your one hundred percent effort, your freeze dried food will only last up until the time indicated on its use-by or best-before date. 

So even if you try your hardest, a freeze dried food that says it can last for ten or fifteen years will only last just as much, and not a day longer.
