Freeze Drying at YallaYum – Explained Quickly and Easily


It’s no longer a secret that YallaYum’s fruit and vegetable pieces are freeze-dried. But what exactly does freeze-dried mean? To help you understand why our fruit snacks are so healthy and aromatic, let’s break down the manufacturing process behind them.

What is Freeze Drying?

Freeze drying, also known as sublimation drying or lyophilization (don’t worry, you don’t need to remember that), is a fascinating and ancient technique: By removing water, food is made to last longer. In Mongolia, for example, meat was freeze-dried 1000 years ago to provide food for soldiers on their long journey to Europe. Similar to that, we offer you fruity vitamins that last.

Where is Freeze Drying Used?

Freeze drying isn’t just used in the food industry. It’s also used in archaeology (for preserving damp wood or leather), in libraries for restoring water-damaged documents, in taxidermy, and in the creation of glossy papers and art prints to prevent them from sticking. In the pharmaceutical industry, freeze drying is used to stabilize active ingredients in medicines, extend shelf lives, and improve dosing accuracy. For food, freeze drying is particularly beneficial as it extends the shelf life and preserves valuable nutrients, vitamins, flavors, and colors. Think of herbs, spices, or instant coffee. Or better yet, think of delicious fruit.

How Does the Freeze Drying Process Work?

Let’s dive into the freeze-drying process with an example: mango. Our mangoes are grown in India and harvested only at full maturity. Many fruits are picked unripe and transported, losing vitamins and taste produced during ripening. That’s why we ensure our fruits are harvested after they’re fully ripe. Six hours after harvesting, the mango is processed into small pieces and frozen by our local partners. This careful process uses large freeze-drying machines to better preserve the vitamins and taste compared to conventional drying methods.

A freeze-drying system consists of two connected chambers. In one, the mango is deep-frozen. Then, it’s moved to a vacuum chamber with a negative pressure of six millibars. Here, a significant amount of water is removed. Interestingly, the moisture from the frozen mango sublimates directly, never returning to a liquid state. What’s left is a freeze-dried mango. The same method applies to our strawberries, black mulberries, and other fruits in the YallaYum range.

What Happens After Freeze Drying?

Once our crispy fruit pieces leave the freeze-drying machine, they are packaged and transported. In collaboration with social workshops, we fill them automatically into our attractive YallaYum packaging. Whether you enjoy them in a fruit smoothie, as a muesli highlight, in a salad, or as a pure snack, our freeze-dried fruits offer fruity and healthy enjoyment.
