Dried Fruit and Freeze-Dried Fruit
In the innovation of healthy snacks, dried fruit is a very popular ingredient due to the delicious taste and nutritional value of various fruits. However, there are various methods for processing dried fruit, such as Dehydration and Freeze Drying. Today, Rimping Supermarket will take you through the differences between these two types of dried fruits.
Dehydrated Dried Fruit: The Traditional, Familiar Method
Dehydration is one of the oldest food preservation methods, with a history spanning centuries. This process involves removing moisture from fresh fruit to extend its shelf life and inhibit microbial growth. This type of dried fruit is typically dried using heat energy, which helps water evaporate from the fruit. It can remove about 80% of the water content and generally has a shelf life of approximately 6-12 months.
After the dehydration process, the fruit becomes sweeter. This is due to the concentration of the fruit's natural sugars as moisture is removed. Additionally, some dried fruits may have added sugar or sulfites to enhance flavor and extend shelf life. Therefore, this type of dried fruit tastes sweeter compared to fresh fruit.
Freeze-Dried Fruit: Innovation for Preserving Nutrients
Freeze Drying is a more modern and technologically advanced method of fruit preservation, differing from traditional heat-drying methods. In freeze-drying, fresh fruit is first frozen at a very low temperature. Then, it is placed in a vacuum chamber where the surrounding pressure is reduced. Under these conditions, the water in the fruit changes directly from a solid (ice) to a gas (Sublimation), a process that helps preserve the fruit's cellular structure and nutrients. This method can remove up to 98% of the moisture.
This freeze-drying technique effectively removes water while retaining almost all of the nutrients, with up to 90% of vitamins and minerals preserved. It is also low in calories, a good source of fiber, and an excellent source of antioxidants.
Furthermore, freeze-dried fruit has a very long shelf life, making it a highly popular choice for those who cannot easily consume fresh fruit, as well as for those looking for a healthy snack throughout the day. Freeze-dried fruits have a crunchy texture and the authentic taste of real fruit, and they are usually made without added sugar or preservatives.
Freeze-dried fruit is popular for its crisp texture and vibrant colors. It can be used to garnish desserts, breakfasts, and beverages. It can also be ground into a powder and sprinkled over smoothies and yogurt.
