PATENTS
Use of pearl shell powder in the preparation of antioxidants
Covers a preparation method that removes the outer shell layer, then crushes and grinds the nacre; molecular biology techniques and animal studies showed significant in vivo antioxidant potential.
Use of pearl powder in the preparation of detoxifying medicines
Combines the strengths of traditional detoxifying medicine with the natural properties of pearl powder, giving the Detox product line solid intellectual-property backing.
Composition for alleviating obesity and promoting gut health
With pearl oyster shell powder of 100–300 nm particle size as its sole active ingredient, it nourishes the gastrointestinal tract, promotes probiotic growth, repairs the gut barrier and inhibits inflammatory responses.
PPRI ERESEARCH
RESEARCH PAPERS
Efficacy of Protein Rich Pearl Powder on Antioxidant Status
A randomized, double-blind, placebo-controlled clinical trial conducted in Taiwan demonstrated that protein-rich pearl powder supplementation enhances total antioxidant capacity in human plasma. This study provides clinical evidence supporting both the human safety and efficacy of pearl powder, as published in the Journal of Food and Drug Analysis.
Pearl Powder — An Emerging Material for Biomedical Applications: A Review
A systematic review detailing the chemical composition, biocompatibility, and biomedical application potential of pearl powder, synthesizing international academic literature across domains such as bone regeneration, skin repair, and antioxidant properties.
Preparation and Characterization of Pearl Powder for In Vivo Heavy Metal Detoxification Potential
An animal study evaluating the physicochemical properties of pearl powder and its potential for in vivo heavy metal detoxification, establishing a scientific foundation for its safety and health application.
SOURCING & TRACEABILITY
Cultivated at Premium Hong Kong Fish Rafts
We partner with top-tier local Hong Kong pearl farms to meticulously select the finest raw ingredients.
Hong Kong Pearl Oyster (Pinctada fucata)
Pearl powder is a fine, natural powder produced by delicately grinding the nacre (mother-of-pearl) layer of high-quality Hong Kong pearl oysters (Pinctada fucata).
Strictly Controlled Manufacturing Process
Our pearl powder is produced through a strictly controlled process to ensure the highest standards of quality and purity.
Purity and Quality Testing
Subsequently, our pearl powder undergoes thorough purity and quality testing to ensure it meets the highest standards prior to packaging and distribution.
OUR MISSION
Reinterpreting the power of pearls through science to drive the revival of Hong Kong's marine heritage.
SAFETY TESTINGS
All products by Pearl Power Research Institute Limited undergo rigorous purity and heavy metal testing.
