Freeze-Drying Industry Advantage

Freeze-Drying (FD) technology can simultaneously meet the demands of food development in the new era, such as green, natural, nutritional preservation, functional stability and convenience and ready-to-eat.

1. Excellent product quality

Freeze-Drying technology has the advantages of reducing enzyme activity, inhibiting microbial growth, non-deteriorating and non-oxidizing material matrix, and less loss of nutritional factors due to its friendly processing technology.

Studies have shown that freeze dried has obvious advantages of active component content and composition retention compared with hot air drying. When using FD technology to process foods such as meat and eggs, freeze-drying technology can make the loss rate of protein and other fat-soluble vitamins (VA, VD) close to zero. Some foreign scholars even claimed that after the development in the next few years, the nutritional level of FD food can be equal to that of fresh food.

2. Wide application of technology

Freeze-Drying technology is not only widely used in the field of food processing. It also occupies an important position in the fields of Chinese herbal medicine processing and biopharmaceuticals.

In terms of food processing, freeze dried technology can process almost all agricultural products, including fruits and vegetables, grains, flavored foods, etc.

In terms of the treatment of Chinese herbal medicines, because the processing methods of most traditional Chinese medicines are relatively simple and the standardization of processing techniques is not high, the overall quality needs to be improved urgently. The study found that the content of flavonoids, polyphenols and essential oils in the ginger leaves after freeze-dried treatment was higher than that in the shade-dried, sun-dried and drying treatments.

In terms of biopharmaceuticals, freeze-drying technology can maintain the stability of drugs and more effectively enhance the biological activity of drugs. FD technology can avoid the influence of external factors during the processing of medicines, so that the activity and quality of medicinal materials can be preserved. In addition, compared with the traditional drying technology, there will be defects such as shrinkage and damage. The freeze-drying technology will not cause excessive damage to the drug formation due to the direct sublimation of water molecules. At the same time, the protection of the biochemical structure of the drug can be satisfied.

3. High value-added products

The research and development, application and promotion of freeze-drying technology can extend and broaden the breadth and depth of deep processing of agricultural products. This greatly improves the added value of agricultural products and the ability to earn foreign exchange from exports, realizes the value-added and efficiency of processing, extends the agricultural industry chain, and enhances the value chain of agricultural products.
