If you’re gearing up for your next big hike, chances are you have some of your favorite healthy snacks ready. But have you considered more time-saving options like freeze-dried foods? According to a 2020 study, freeze-dried foods, which are foods that are deep-frozen and then vacuum-sealed to preserve freshness, are a healthy nutritional alternative to salty snacks. The actual food freeze-drying process does not compromise the size or nutrient density of the final product.
While freeze-dried fruit has proven to be a healthy snack, the options aren’t limited to produce, either.

Freeze-dried food has practical benefits
Now that you know that freeze-drying doesn’t take away from a food’s nutritional value, there are more reasons why campers, and specifically hikers, pack freeze-dried meals even for an afternoon in the woods. First, freeze-dried foods weigh less than fresh or dehydrated options, since about 98% of the water is removed in the freeze-drying process (via Women’s Health). According to The Takeout, each backpacking meal weighs about 6 ounces, making them a great choice if you plan on carrying around 20% or more of your body weight (according to FarOut).
Another reason hikers enjoy freeze-dried meals is that they’re shelf-stable and don’t need refrigeration (via the USDA). According to the Mountain House website, their freeze-dried meals can last up to 30 years.

Freeze-drying does not affect calorie count, fiber content, or total mineral amounts. It can make a difference with some water-soluble vitamins, like folate and vitamin C. See the article : The dog food that is remembered after the tests finds Listeria’s presence. But most of the nutritional value will be retained.
Does freeze drying destroy vitamins? In this way, freeze-dried foods can be even better for your health than fresh foods. Vitamin A (which plays an important role in eye, bone, and immune system health) along with vitamin C begin to break down quickly in traditional dehydrators. But freeze-drying stops that degradation and keeps the vitamins intact.

However, according to the American Institute for Cancer Research, freeze-dried foods retain the vast majority of vitamins and minerals found in their original state.

In fact, freeze-dried foods typically retain 97 percent of their nutrients due to the cold vacuum process used to extract the water.
Is freeze-dried as healthy as fresh?
Like freezing, freeze-drying helps preserve nutrients. However, we will still see losses in these, especially vitamin C. But since freeze-dried fruits contain less water than fresh fruits, you could end up eating more pieces of them than fresh, which means more nutrients (but also more energy and sugar). . ).

Freeze-dried foods are of superior quality compared to foods dehydrated by other methods. The high quality is due to the absence of a liquid phase, as well as the low temperature of the process. Freeze-drying preserves flavor, color, and appearance while minimizing thermal damage to heat-sensitive nutrients.
