OUR HERBAL EXTRACT MANUFACTURING PROCESS
Quality begins with using the right spices of raw herbs, depending on the complied standard extraction method, achieving with the strict inspection standard

Step I Raw Materials

Herbal extract products supplied by Hefei Dielegance Biotechnology Co., Ltd., including liquid, oil and powder form products, are manufactured from premium quality raw materials that must pass a series of stringent inspections performed by in-house professional technicians utilizing our state-of-the-art process and precision instruments.

Species Identification:

•  Organoleptic (physical) Inspection
•  Microscopic Inspection
•  Thin Layer Chromatography (qualitative)
•  High Performance Liquid Chromatography (quantitative)

Heavy Metal/Pesticide Inspection:

•  UPLC-ICP-MS – Heavy Metal
•  UPLC-MS/MS – Pesticides
•  GS-MS/MS – Pesticides

Chemistry Analysis:

•  The herbs are analyzed for its moisture content, purity, extraction and other properties.

Only upon passing the above inspections for quality, identity and safety, may the herb material be accepted into our facility for further processing.

​​​​​​​Step II Preparation & Verification

Once accepted, the herbs go through a meticulous cleaning until dirt and foreign materials are removed. It then goes through a process known as “paozhi”, done in accordance to specified methods unique to each specific herb where necessary. We pride ourselves in our commitment in adherence to traditional methods, for example, there are instances such as when herbs are to be input into a formula decoction at specified stages, rather than all at once. 

​​​​​​​Step III Extraction

The herbs are placed in a rotary extractor which spins to mix the herbs in a decoction liquid while the temperature is increased to cook the herbs. The precise extraction temperature and timing is strictly controlled to maximize efficiency and thoroughness.

​​​​​​​Step IV Herbal Concentration

The extracts in liquid form flows through a pipeline directly into a state-of-the-art concentration system. The liquid gradually condenses through low temperature evaporation. The low-temperature preserves the potency of the herbal extract potency that would otherwise be damaged under extended exposure to high temperatures.

The duration is adjusted until the best herb-to-solute ratio is ascertained. Because each herb/formula have a different optimal herb extraction ratio. Optimal Extraction is what Dielegance Biotechnology consistently strives for.

Step V Granulation

The concentrate, now in the form of a viscous paste, is piped into a flow coater. The concentrated paste is sprayed onto minute particles of a base material as the moisture slowly dissipates. The flow-coater’s process is automated, and it is completely sealed off to prevent the possibility of cross-contamination. The base material is formed using non-GMO maltodextrin and/or ground herbs depending on the formulation. With the moisture evaporated, the result is a fine, free flowing extract granule that is now ready to be packaged, or further processed into easy-to-swallow tablets or capsules.

Step VI Packaging & Appearance

Like all plant products, the characteristics of herbs vary from season to season and year to year depending on the environment in which the herbs were picked. Naturally, it is normal for the resulting granules to vary slightly in color, texture or aroma, reflecting the variations in the source herbs from which they were produced. Dielegance’s herb granule extracts are produced in batches with each batch assigned a unique lot number, which can be found in the bag label.

Step VII Final Inspection

Dielegance’s in house laboratories will analysis multiple samples from each production lot to measure the quality, safety and efficacy of the product, employing the state of the art precision instruments and methods against:

These tests include the following:
•  HPLC- Marker ingredient analysis and verification
•  UPLC-ICP-MS – Heavy Metal Analysis
•  UPLC-MS/MS and GS-MS/MS – Pesticides Screening (up to 507 pesticide detection capability)
•  Microbial screening (E. Coli, Salmonella, Yeast and Mold, etc.)

Upon passing our finished product testing, a Certificate of Analysis (COA) will be issued. The COA documents the excellent quality of our herbal extracts. No batches of products will leave the Dielegance Biotechnology manufacturing facility without a COA that proves that the strict standards of Hefei Dielegance Biotechnology Co., Ltd. has been achieved.
