Manufacturing & Processing Excellence
Precision Membrane Separation
Crude vine tea extracts contain inert botanical waxes and tannins. We deploy advanced cross-flow membrane ultrafiltration prior to crystallization. This specifically isolates the dihydromyricetin fraction, ensuring our 98% grade maintains exceptional optical clarity and formulation stability.
Strategic Gradient Purity
Our multi-tier specification directly aligns with your budgetary and product positioning. The 50% grade is highly cost-effective for bulk food preservation and animal nutrition, while the 98% monomer is clinically optimized for high-end nutricosmetics and premium hepatoprotective capsules.
Zero Chemical Additives
In the food and cosmetic industries, clean labels are paramount. Our extraction process strictly avoids the use of synthetic chemical preservatives, allowing you to leverage DMY as a fully natural, plant-based antimicrobial and antioxidant additive.
Biochemical Mechanisms & Antioxidant Action
Acetaldehyde Clearance (Hepatoprotective Support)
In toxicological models of acute alcohol exposure, DMY actively accelerates the enzymatic degradation of acetaldehyde-the primary toxic metabolite of ethanol. This physiological mechanism reduces cellular oxidative stress within hepatocytes, providing robust, clinically validated support for liver health and rapid hangover mitigation.
DPPH Free-Radical Scavenging (Antioxidant)
As a highly concentrated polyhydroxy flavonoid, Dihydromyricetin demonstrates exceptional efficacy in neutralizing DPPH and ABTS free radicals. It inhibits lipid peroxidation in both biological cellular membranes and industrial vegetable oils, serving as a powerful dual-use antioxidant.
Broad-Spectrum Antimicrobial Action
DMY exhibits notable inhibitory effects against a wide range of gram-positive and gram-negative bacteria, as well as specific molds and yeasts. This broad-spectrum bacteriostatic property makes it an invaluable natural preservative agent for extending the shelf life of food matrices and cosmetic emulsions.
Industrial Application Scenarios
Premium Hangover & Liver Support
The core active ingredient for formulating clinical-grade hangover recovery capsules, liver-protection tablets, and social functional drinks.
Advanced Nutricosmetics & Skincare
Heavily specified in dietary complexes and topical serums aimed at mitigating oxidative stress, photoaging, and supporting cellular repair.
Natural Food & Oil Preservation
Utilized as a potent, clean-label antioxidant to inhibit lipid peroxidation in vegetable oils, meats, and bakery goods, effectively replacing synthetic preservatives.
Disinfection & Personal Hygiene
Integrated into natural antibacterial body washes, clothing care liquids, and skin-refreshing sprays due to its broad-spectrum antimicrobial profile.

Formulator & Procurement FAQ
Q1: Will the antioxidant performance of Dihydromyricetin improve with higher purity?
Yes, there is a strong positive correlation. Higher purity specifications (≥90% and ≥98%) demonstrate significantly more potent free radical clearance and oil oxidation inhibition capacities. For high-end premium supplements and demanding clinical applications, we strongly recommend our 98% grade to ensure maximum active bioavailability.
Q2: Can DMY fully replace synthetic chemical preservatives in food and cosmetics?
When strategically formulated, yes. While DMY is a powerful broad-spectrum antimicrobial and antioxidant on its own, compounding it with a small percentage of polyols (like glycerin or propylene glycol) can establish a complete, robust natural preservative system. This is an ideal solution for organic, clean-label food and skincare brands looking to phase out parabens and synthetic antioxidants.
