Freeze Dried Snacks: Surprising Facts You Should Know

As the benefits of freeze dried snacks continue to emerge, they have gradually transitioned from being a niche product to a mainstream choice. Most consumers have tasted freeze dried snacks to some extent, yet many are only vaguely familiar with them. Today, we’re here to share some lesser-known facts about freeze dried snacks.

What Are Freeze Dried Snacks?

Freeze dried snacks are made using a freeze-drying process, where the raw material is placed in a vacuum chamber at temperatures as low as -35°C. In this environment, their moisture rapidly freezes and sublimates into vapor. This method eliminates the need for preservatives and additives, making it possible to create snacks with 100% natural ingredients. Take freeze dried fruit, for example: after undergoing the freeze-drying process, the fruit retains its original flavor and nutritional content while offering a new way to enjoy fruit snacks.

Do Freeze Dried Snacks Need Refrigeration?

Freeze dried snacks are processed in a low-temperature, oxygen-free environment, they are completely dehydrated once finished. As such, they can be stored at room temperature without the need for refrigeration.

Can Freeze Dried Snacks Retain All Their Nutrients?

Freeze-drying technology helps retain over 90% of the nutrients in fruits or vegetables. Compared to other preservation methods like candied fruits, oven-dried fruits, or low-temperature fried vegetables, freeze dried snacks are among the top options for maintaining nutritional integrity.                       

Why Is Packaging for Freeze Dried Snacks Inflated?

Freeze dried fruits and vegetables are lightweight, and to prevent them from becoming powdery due to shifting and impacts during transport, the packaging is often inflated with an anaerobic gas. This further helps preserve their freshness and prevents oxidation. Compared to fried snacks, freeze dried snacks provide the same crispy texture but with lower calories and more nutrients, making them an ideal choice for health-conscious consumers.

Are Freeze Dried Snacks Really Free of Preservatives?

Yes, freeze dried snacks are typically free of preservatives, thanks to the unique freeze-drying process. Unlike traditional methods of preservation such as canning or adding chemical preservatives, freeze-drying removes the moisture from the fruit without the need for any artificial additives.

However, it’s important to note that once the packaging is opened, the snacks can absorb water and spoil. This is why freeze dried snacks are typically packaged in vacuum-sealed bags, sometimes with added inert gases to keep oxygen out and preserve freshness.

However, consumers should always check the label for any potential added ingredients, especially in flavored or processed varieties, as some may include extra sweeteners, flavorings, or other additives.

Are All Freeze-Dried Snacks Crispy?

Not all freeze dried snacks are equally crispy. Depending on the varieties, some might have a more delicate, airy texture rather than being crunchy. Regardless of the texture, freeze dried vegetables and fruits have a strong tendency to absorb moisture from the air, so they will soften if exposed to humidity. Remember to seal the packaging tightly after opening to maintain their crispness.

What’s the Difference Between VF and FD?

The acronym FD stands for "Freeze-Drying," or "Vacuum Freeze Drying." Many products on the market use terms similar to freeze-drying, such as low-temperature vacuum dehydration, low-temperature oil bath drying, or VF (Vacuum Frying). However, these are not true freeze-drying processes, so it’s important to distinguish them when shopping.
