How Freeze-Dried Fruit is Made
The freeze-dried fruit production process is actually quite simple. After fresh fruit is picked, it's immediately frozen to -40°C using a quick-freezing process. Then, vacuum dehydration is used to sublime the water in the fruit directly into a vaporous state. This process not only preserves the fruit's original color, aroma, and shape, but also allows nutrients to be retained within the frozen ice, achieving a retention rate of over 95%. Freeze-dried fruit has a dehydration rate of up to 95%, requiring no preservatives and can be stored at room temperature for a year or more.
Nutritional Value
When you enjoy a bag of freeze-dried fruit, you're actually getting the nutritional benefits of ten times its weight in fresh fruit. Generally, 500 grams of fresh fruit can yield 50 grams of freeze-dried fruit. Freeze-dried fruit is rich in dietary fiber and easily digestible, making it a popular snack for all ages.
Production Method
Freeze-dried fruit is primarily produced using a freeze dryer. Using a vacuum freeze-drying process, the moisture in the fruit is frozen and then sublimated under a vacuum, resulting in the freeze-dried fruit. Simply put, the moisture is extracted from the fruit at low temperatures, preserving its original nutrients.
Easy to Carry and Store
Freeze-dried fruit not only resembles fresh fruit in color and shape, but also has a crisp texture and can be restored to its original shape after soaking. It's convenient to carry and store, making it a popular snack for all ages.
Suitable Customers
Freeze-dried fruit is a wise choice for people with diabetes. When experiencing hypoglycemia, replacing cookies and candies with a small amount of dried fruit is a good option to raise blood sugar levels, as it provides more potassium, dietary fiber, and antioxidants. International studies have found that replacing cookies and biscuits with raisins can help control blood pressure and have a positive impact on blood sugar and cardiovascular markers.
Nutrient Preservation
Freeze-dried fruit differs from ordinary sun-dried fruit in that it extracts moisture from the fruit at low temperatures, minimizing the loss of volatile components and effectively preserving the original nutrients of the fresh fruit. Furthermore, the freeze-drying process prevents microbial growth and enzyme activity, allowing the fruit to retain its original shape. Freeze-dried fruit offers advantages in terms of nutrient loss, taste, and appearance.
Dietary Fiber
People often spit out or peel the skin of fruit, otherwise they find it difficult to swallow. However, the peel is the highest concentration of dietary fiber in the fruit, and drying preserves this fiber completely. Freeze-dried fruit not only retains its original flavor but also provides a rich source of dietary fiber. It's easy to carry and store, making it a healthy snack for all ages.
