Proprietary freeze-drying technology

Preserving the delicate natural active ingredients in Yunzhi

The propriety concentration and extraction technologies (which include freeze-drying at sub-zero temperatures) used for extracting ONCO-Z®, the active ingredient which contains Absorbable Peptidoglucan (APG), is exclusively developed, owned and utilized by Purapharm for the production of Oncozac®. This is an important step in ensuring Oncozac®'s effectiveness since the active ingredients from the Yunzhi extracts are highly heat-sensitive and easily denatured during the traditional extraction methods used by other manufacturers to produce other Yunzhi products on the market. Our patented production process solves this long-standing problem and helps to maintain the biological vitality of Yunzhi extracts during the thermal drying process.

Oncozac® has over 10 patents.. Our trademarked ingredient ONCO-Z® contains Absorbable Peptidoglycan (APG), an active ingredient that can be more easily absorbed by the human body

Extracting essential molecules which are finer and more easily absorbable

Compared with traditional extraction technologies, freeze-drying can be more time and cost-consuming, but in return, the Yunzhi extracts produced through our patented freeze-drying technology* are scientifically proven to be up to 6 times more potent8 in stimulating the immune system compared to similar products on the market.Compared with traditional extraction technologies, freeze-drying can be more time and cost-consuming, but in return, the Yunzhi extracts produced through our patented freeze-drying technology* are scientifically proven to be up to 6 times more potent8 in stimulating the immune system compared to similar products on the market.

*Our extraction methods were patented in the United Kingdom and the United States in April 2006 and May 2006 respectively.

Extraction

Active ingredients are extracted from Yunzhi under controlled temperatures and time to ensure optimal preservation of heat-sensitive ingredients.

Freezing

Yunzhi extracts are subsequently frozen at a specific temperature to prevent denaturing of active ingredients.

Drying

To remove any traces of residual moisture, a sequence of controlled temperatures are used in the drying process.

Quality assurance

From harvesting to product release

Purapharm's Nanning manufacturing facilities

CNAS-certified laboratory

Harvesting the best of Yunzhi

採集雲芝中的精品

Purapharm® sources Yunzhi from its natural origins and constantly makes improvements on methods to identify, process, and authenticate the finest Yunzhi at our manufacturing plant in Nanning.

Screening & pre-production

12,000 m<sup>2</sup><br/>CNAS-certified laboratory

All Yunzhi mushrooms are manually selected. Unusable parts such as mycelium are removed. Any form of impurity, corruption (from vermin or deterioration), and debris are screened out.

Cleanroom floor area

7000 ft.2

Freeze-drying process

Selected Yunzhi are processed under highly controlled conditions to ensure active ingredients stay undamaged and are not denatured during the production process.

Grinding

Dried extracts that pass our Quality Assurance assessments are then ground to a fine powder.

In-house tests

12,000 m<sup>2</sup><br/>CNAS-certified laboratory

Physical, chemical & hygiene tests are conducted in the Purapharm labs to ensure the quality of Oncozac®.

Capsulation

Each batch of Oncozac® receives safety reports of heavy metals & toxic elements, pesticide residues, and microbial limit tests before they are capsulated and deemed shelf-ready.

Safety tests & immunological bioassay

External tests on the final products, capsules, and bottles are conducted by the world-renowned independent testing laboratory SGS (H.K.) Ltd.

Packaging & product release

Oncozac® capsules are sealed in the aluminium-plastic composite film to minimize any risk factors that may lead to a deterioration in quality.
