Freeze Dried Fruit Tea is a healthy drink made by processing fruits through advanced freeze-drying technology. It retains the natural nutrients and original flavor of fruits, while being easy to store for a long time and convenient to brew.Compared with traditional fruit tea, the fruits in Freeze Dried Fruit Tea are freeze-dried at low temperature and vacuum, so that the moisture is completely removed, but the vitamins, minerals and natural aroma of the fruits can be retained to the maximum extent.
Just brew Freeze Dried Fruit Tea with warm or cold water to enjoy the deliciousness and nutrition of fresh fruits. With the increasing demand for healthy drinks, Freeze Dried Fruit Tea has gradually become a new type of drink that is popular in the market due to its health, convenience and rich nutrition.
Production process and technology of Freeze Dried Fruit Tea
Freeze-drying technology preserves the nutrients, color and taste of fruits by freezing them quickly at low temperatures and removing moisture in a vacuum environment, and can preserve them for a long time.
Material selection and raw material preparation
The first step in producing Freeze Dried Fruit Tea is to select high-quality fresh fruits. Commonly used fruits include strawberries, blueberries, lemons, apples, oranges, etc. These fruits are often used in the production of freeze-dried fruit tea because of their rich vitamins, antioxidants and natural aroma. Fruits need to be strictly screened to ensure that there are no rotten, damaged or contaminated fruits. At the same time, the appearance, color, taste and nutritional content of the fruits must also meet production standards.
Next, the fruits will be washed, peeled, and pitted to ensure that the raw materials are clean and suitable for freeze-drying. Depending on the characteristics of different fruits, cutting or slicing may be required for the subsequent freeze-drying process.
Freeze-drying process
Lyophilization is the core technology of production. Unlike traditional hot air drying and freeze drying technologies, it can maximize the retention of nutrients and natural flavors of fruits.
The specific steps are as follows:
- Freezing: The treated fruit is quickly frozen to extremely low temperatures, usually between -30°C and -50° The purpose of this step is to convert the water in the fruit into ice crystals, maintain the cell structure of the fruit, and avoid damaging the fruit’s tissue structure during the water removal process.
- Vacuum dehydration: The frozen fruit is placed in a vacuum environment, usually in a vacuum freeze dryer (also known as a freeze dryer). By reducing the pressure, the water in the fruit is directly converted from ice to gas (sublimation), avoiding the presence of liquid water. This process is carried out at low temperatures, so the nutrients of the fruit, such as vitamins, minerals and natural aroma, are retained to the greatest extent.
- Drying process: After the sublimation process is completed, the water in the fruit is almost completely removed. At this point, the fruit still retains its original shape, color and aroma. The entire freeze-drying process usually takes 24 hours or more, depending on the type of fruit and the specifications of the freeze dryer.
Post-processing and packaging of finished fruit tea
Freeze-dried fruit will be very light and usually brittle after dehydration. In order to ensure the best quality of freeze-dried fruit tea, some post-processing steps are required:
- Screening and sorting: During the freeze-drying process, some unqualified products may appear, such as broken fruit pieces or fruits with uneven colors. Therefore, the freeze-dried fruits need to be screened to ensure that the appearance and quality of the final product meet the standards.
- Crushing and mixing: If necessary, the freeze-dried fruits can be crushed according to demand to make freeze-dried fruit powder, or mixed with other ingredients (such as flowers, tea leaves, spices, etc.) to make a variety of flavors of fruit tea combinations. This can increase the taste and diversity of the product.
- Packaging: The processed Freeze Dried Fruit Teawill be packaged in small bags, cans or bulk forms. The packaging usually uses well-sealed bags or cans to prevent air and moisture from entering, ensuring the long-term storage of the product and the stability of the taste. In order to extend the shelf life of the product, some Freeze Dried Fruit Tea may also add antioxidants to prevent the degradation of color and flavor.
Advantages of freeze-drying technology
Compared with other drying methods, the biggest advantage of freeze-drying technology is that it can retain the nutrients and original flavor of the fruit. Through the low-temperature sublimation process, Freeze Dried Fruit Tea can maintain the delicious taste, natural aroma, and rich nutritional value of the fruit.
How to brew and drink Freeze Dried Fruit Tea
Put an appropriate amount of Freeze Dried Fruit Tea into a cup, add hot water (about 80°C to 90°C), and stir gently. Hot water can activate the aroma and taste of the fruit, release rich natural juice, and bring a warm and refreshing taste. This brewing method is suitable for drinking in cold weather, which can warm the body and enjoy the natural flavor of the fruit.
In order to increase the taste level, you can add some ingredients when brewing Freeze Dried Fruit Tea, such as honey, lemon slices, mint leaves or tea leaves (such as green tea, black tea, etc.). These ingredients can further enrich the flavor of the drink and make Freeze Dried Fruit Tea more personalized and creative.
If you like a sweeter taste, you can add an appropriate amount of sugar or sweetener according to your personal preference. The combination of the natural fruity aroma of Freeze Dried Fruit Tea and sweeteners can be used to prepare a drink that suits your taste.
