Vacuum freeze-dried food is a type of food produced using vacuum freeze-drying technology. The process involves freezing the food into a solid at low temperatures, and then under vacuum conditions, directly converting the solid solvent into water vapor, thereby removing moisture from the food and creating lightweight, easy-to-store freeze-dried food. Common types of vacuum freeze-dried foods include vegetables, fruits, meat, seafood, and more.
During the freeze-drying process, the moisture in the food is removed, but the nutritional components of most foods remain largely unchanged because the low temperatures and vacuum conditions significantly reduce the oxidation and heat sensitivity of the nutrients. However, due to the reduction in moisture content, the volume and weight of the food decrease, which means that the relative percentage of nutrients per serving increases.
Overall, vacuum freeze-dried foods, compared to fresh foods and heat-processed foods, can retain their nutritional components and flavor, and have a longer shelf life with more convenient storage and transportation options. As a result, they are becoming increasingly popular in modern food processing and storage.
In addition to maintaining nutritional content and reducing volume, vacuum freeze-dried foods also have the following characteristics:
1. Maintaining the color, aroma, and taste of the food: During the freeze-drying process, the color, aroma, and taste of the food are mostly preserved, ensuring excellent flavor and texture.
2. Convenient for carrying and storage: The removal of moisture greatly reduces the volume and weight of the food, making it easier to carry and store.
3. Extended shelf life: Since the moisture has been removed from vacuum freeze-dried food, its shelf life is significantly extended, making the food safer and more reliable.
4. Better preservation of nutritional components: As freeze-dried foods do not require high-temperature processing, they effectively preserve the nutrients, making them an excellent choice for those who have specific nutritional requirements.
The production of vacuum freeze-dried food requires freezing followed by the vacuum freeze-drying process. The freezing process is also important because different foods may require different freezing temperatures and times. Furthermore, producing vacuum freeze-dried food requires specialized vacuum freeze-drying equipment, as small kitchen devices are generally incapable of performing this process.
