Frozen Solution is one of vacuum freeze drying methods, which is widely used in food fruits and vegetables. Here we discuss the advantages of frozen solution in freeze-drying vegetables and carrots.
Carrots have high nutritional value and contain many nutrients needed by human body. With the development of economy and the improvement of people's living standard, people are more interested in green, healthy and non-added food. Carrots freeze-dried in a low-temperature vacuum environment through frozen solution are easy to store, eat and deeply process, and have good market prospects.
Carrots have many drying methods. Hot air drying was the common drying method before. However, the hot air drying cycle is long and the drying quality is poor. The emergence of frozen solutions provides an alternative to low-temperature drying, which allows moisture removal at low temperatures and pressures. Therefore, the vacuum freeze drying of the Fruit Processing Machine can have lower drying temperature and anoxic treatment environment. The freeze-dried carrot not only retains its original color, shape and taste, but also retains its thermosensitive components due to drying at low temperature, thus retaining its original nutritional components.
