What is Freeze-Dried Cold-Brew Herbal Powder?
Freeze-dried cold-brew herbal powder is a high-quality, nutrient-dense formulation produced by cold-brewing medicinal herbs (such as traditional Chinese botanical extracts) in chilled or room-temperature water, followed by freeze-drying the extract. This advanced technique preserves the bioactive compounds, phytochemicals, aroma, and natural flavors of the herbs while significantly enhancing the product's shelf stability and efficacy.
With a growing interest in nutraceutical beverages, this innovative format is gaining popularity due to its superior nutritional profile, ease of use, and extended shelf life.
How to Make It
Step 1
Preparing the Herbs
Preparing the Herbs
The process begins with the careful selection and preparation of high-quality herbs. Selected botanicals are washed, sanitized, and mechanically processed into smaller particles to increase surface area and enhance extraction efficiency.
Step 2
Cold Extraction (Cold Brewing)
Cold Extraction (Cold Brewing)
The critical extraction phase involves immersing the prepared herbs in chilled or ambient water over a prolonged duration. This low-temperature extraction method preserves heat-sensitive bioactive compounds, maintaining the herbal material’s integrity and potency.
Step 3
Freeze-Drying (Lyophilization)
Freeze-Drying (Lyophilization)
The cold-extracted herbal solution undergoes rapid freezing, followed by vacuum sublimation in a controlled environment. This process removes moisture by transitioning ice directly to vapor, bypassing the liquid phase. Freeze-drying preserves the molecular structure, nutritional content, and volatile compounds of the herbal extract.
Step 4
Pulverization & Packaging
Pulverization & Packaging
The dried herbal material is finely milled into a uniform powder and packaged under sterile, airtight conditions to prevent contamination and preserve bioavailability.
Temperature & Time Control
Cold brewing needs the right water temperature and soaking time. Freeze-drying also needs perfect freezing/drying times.
Vacuum Power
Adjusting the vacuum strength helps ice turn into vapor faster during freeze-drying.
Mixing Magic
We tweak how much liquid we used based on the herb type to get the best results.
