SUNSAY Freeze-drying Technology – Solution for processing, preserving herbs and herbal teas

The development of food processing technology, especially in the field of herbs and herbal teas, requires advanced preservation methods to maintain nutritional and medicinal values. SUNSAY freeze dryer, with the ability to dry at low temperatures, has become an indispensable tool in the process of processing and preserving herbs and herbal teas, helping to optimize product quality and meet domestic and foreign market demand.

Benefits of freeze-drying technology in preserving herbs and herbal teas

One of the biggest advantages of freeze-drying is the ability to maintain almost all the bioactive substances in herbs. Low temperatures (usually below 40°C) help to preserve important substances such as alkaloids, flavonoids, vitamins and other nutrients in tea and herbs.

Drying at low temperatures limits the oxidation of volatile compounds, helping the product retain its bright color and natural aroma. This is especially important for herbal teas, where flavor and aroma are key to quality.

In the traditional drying process, rapid dehydration can lead to product weight loss due to shrinkage, cracking or deformation. SUNSAY freeze-drying technology helps retain the original shape and size of herbs and tea leaves, resulting in a final product with a beautiful appearance and no mechanical damage.

Freeze-dried products have very low moisture content, creating unfavorable conditions for microbial growth, helping to prolong the shelf life of herbs and herbal teas without the use of chemical preservatives.

Applications in herbal processing

Herbs, with the characteristic of containing many active ingredients beneficial to health, require strict processing and preservation procedures to maintain their pharmacological effects. Some common herbs that can be dried with SUNSAY freeze dryers include: ginseng, lingzhi mushroom, lemon basil leaves, green tea leaves, and medicinal flowers such as chrysanthemum and artichoke.

Ginseng: For ginseng, preserving the active ginsenosides is very important. Freeze-drying helps maintain all of these valuable compounds without causing them to be destroyed by heat.

Ganoderma lucidum: This herb contains many polysaccharides and triterpenoids, which are very sensitive to heat. SUNSAY freeze dryer helps preserve these compounds intact, ensuring the medicinal effects of the mushroom after drying.

Herbal leaves: Such as green tea leaves and lemon basil, need careful processing to retain maximum polyphenols and flavonoids, two main active ingredients with antioxidant effects. SUNSAY freeze-drying technology is the optimal choice for these products.

Applications in herbal tea processing

Herbal teas are increasingly popular due to their outstanding health benefits, from aiding digestion to improving sleep. To preserve these values, the use of freeze-drying in the production process is extremely necessary.

Chamomile tea: Chamomile is a flower that contains many essential oils and flavonoids that have anti-inflammatory and detoxifying properties. If high temperatures are used, these compounds can evaporate or change. Freeze-drying helps retain all the essential oils, ensuring natural flavor and therapeutic effects.

Artichoke tea: Artichoke is one of the famous tea ingredients with the effect of cooling and detoxifying the liver. The freeze-drying process not only retains the antioxidants but also preserves the natural shape and color of the artichoke, thereby enhancing the sensory value of the product.

Lotus leaf tea: Lotus leaves help lower blood fat and support weight loss. When using freeze-drying technology, lotus leaves retain their fresh green color and light aroma, while beneficial active ingredients are not destroyed, ensuring effective use.

Comparison with other drying methods

When comparing freeze drying with traditional high temperature drying methods, such as convection drying or electric drying, the obvious difference lies in the ability to preserve herbs and herbal teas and the quality of the product, especially with herbs and herbal teas.

In the high-temperature drying method, the temperature applied to the raw materials often exceeds 60-90°C, causing volatile compounds, such as essential oils and important nutrients, to decompose or disappear. This leads to a decline in product quality, changes in color, flavor, and reduces the pharmacological effects of the herbs.

Convection drying methods use hot air to dry the product, but this speeds up the oxidation process and reduces the nutritional content of the herbs. In addition, high temperatures can easily caramelize the sugars in the ingredients, changing the natural flavor and making the product darker and less visually appealing. These factors are especially harmful to herbs and herbal teas, which are popular for their natural properties.

In contrast, the freeze-drying technology of SUNSAY dryers operates at much lower temperatures, below 50°C, creating ideal conditions to preserve all valuable compounds in herbs such as flavonoids, polyphenols and essential oils.

The low temperature in freeze-drying helps maintain bright colors, original flavors and nutritional components without loss due to temperature. In particular, freeze-drying does not change the physical structure of the raw materials, helping the product retain its original shape, creating a final product with a beautiful and uniform appearance.

Furthermore, freeze-drying also offers the ability to extend the shelf life of natural herbs and herbal teas without the need for chemical preservatives. Freeze-dried products have very low moisture content, below the level where bacteria or mold can grow, which helps ensure that the product maintains high quality throughout the storage process.
