With the popularity of the concept of healthy diet, freeze-dried fruits and vegetables have gradually become a new favorite in People's Daily diet. This new food processing technology not only retains the original nutrition of fruits and vegetables, but also brings unexpected taste experience. Let's step into the world of freeze-dried fruits and vegetables and discover the story behind this delicious food.
Freeze-drying of fruits and vegetables, full name freeze-drying, is a technology that sublimates the water in fruits and vegetables directly after freezing. The technique dehydrates fruits and vegetables by rapidly freezing them to extremely low temperatures and then heating them in a vacuum to sublimate the ice directly into water vapor. This processing method can maximize the retention of fruit and vegetable color, flavor and nutrients.
Compared with traditional drying methods, freeze-drying technology has the following significant advantages:
1. Nutrition retention: Because it is carried out in a low temperature environment, the lyophilization process can better retain nutrients such as vitamins and minerals in fruits and vegetables.
2. Good rehydration: freeze-dried fruits and vegetables are easy to return to their original state after water, which is easy to prepare before eating.
3. Crisp taste: Freeze-dried fruits and vegetables have a unique crisp taste because their internal structure forms a porous structure during the freeze-drying process.
4. Easy storage: the weight of fruits and vegetables after dehydration is greatly reduced, and the storage period is longer at room temperature, and it is easy to carry and store.
There are many kinds of freeze-dried fruits and vegetables on the market today, including common apples, bananas, strawberries, pineapples, mangoes, etc., and some uncommon chia seeds, blueberries, sweet potatoes, pumpkins and so on. These freeze-dried fruits and vegetables can not only be eaten directly, but can also be used to make tea, make salads or as baking ingredients.
In addition to direct consumption, freeze-dried fruits and vegetables have a variety of ways to eat:
Eat after rehydration: Soak freeze-dried fruits and vegetables in water for a few minutes to restore their original taste and nutritional value.
Add to yogurt or cereal: Add nutrition and texture to breakfast.
- Make healthy snacks: for example, after slicing freeze-dried fruits and vegetables, make vegetable strips or dried fruits, which are healthy and delicious.
Freeze-dried fruits and vegetables are becoming a new trend in the health food market because of their unique processing technology, rich nutrients and various eating ways. With the growing consumer demand for healthy food, fruit and vegetable freeze-drying will play an increasingly important role in the future. Whether as a daily snack or as part of a healthy diet, freeze-dried fruits and vegetables are an option that cannot be ignored.
