Dihydromyricetin Bulk Powder

Dihydromyricetin Bulk Powder is a high-purity flavonoid compound extracted from natural plants such as vine tea. With its excellent physiological activity and wide range of applications, it has become a highly anticipated functional raw material.

Choose Lymall Bpanda's Dihydromyricetin powder to infuse your products with a natural, safe, and highly effective technological core, and together we will lead a new way of healthy living.

1. Raw Material Inspection (Incoming Inspection)

All incoming Ampelopsis thunbergii (vine tea) raw materials undergo rigorous authenticity verification using thin-layer chromatography (TLC) fingerprinting and macro/microscopic identification. Simultaneously, gas chromatography-mass spectrometry (GC-MS) and inductively coupled plasma mass spectrometry (ICP-MS) are used to screen for pesticide residues, heavy metals, and aflatoxin, ensuring that only safe and uncontaminated plant sources enter the production line.

2. Process Quality Control (In-Process Control)

During the extraction, purification, and crystallization stages, key process parameters such as extraction solvent ratio, temperature, pH value, and crystallization time are continuously monitored and recorded. Intermediate products are sampled and tested in real time to ensure the structural integrity of dihydromyricetin molecules and prevent the formation of byproducts, thereby ensuring strict batch-to-batch consistency.

3. Comprehensive Finished Product Testing
Each batch of final bulk finished product undergoes full-spectrum analysis to meet stringent specifications:

• Purity and Activity Content: Quantitative analysis using high-performance liquid chromatography-ultraviolet detection (HPLC-UV) ensures high standardized content (e.g., dihydromyricetin ≥ 98% on dry weight).
• Microbiological Limits: Testing for total bacterial count, yeasts and molds, Escherichia coli, and Salmonella ensures hygiene and safety.
• Heavy Metals: ICP-MS testing for elements such as lead, arsenic, cadmium, and mercury ensures levels are strictly below permissible limits.
• Residual Solvents: GC-MS testing ensures all processing solvents meet food-grade safety standards.

We guarantee superior purity (>98%) through rigorous HPLC testing. Dihydromyricetin Bulk Powder is 100% natural, non-GMO, and free from unnecessary fillers, allergens, and heavy metals. We specialize in a low-particle-size formulation that ensures excellent solubility and mixing, making it ideal for both manufacturing (nutraceuticals, sports nutrition) and personal use in smoothies or beverages.

1. Raw Material Source: Own Bases and Partner Farms
We have established our own standardized planting bases in the core production area of ​​vine tea and signed targeted planting agreements with large local farms. We manage seedling selection and field plant protection throughout the entire process, securing high-quality, pollution-free vine tea resources.

2. Standardized Raw Material Management: Graded Harvesting and Initial Inspection & Storage
We clearly define the optimal harvesting season and leaf maturity. Fresh leaves undergo rapid initial processing after harvesting, and the initial dihydromyricetin content is tested. Raw materials are graded and stored according to content to ensure stable activity levels across batches.

3. Supply Stability: Annual Price Lock-in Agreements and Priority Supply
We have signed annual strategic price lock-in agreements with core production areas and simultaneously provide upstream planting support to partners. This deep resource binding ensures priority supply rights during periods of surging market demand, preventing market speculation.

4. Traceability System: Closed-Loop Batch Management Throughout the Entire Lifecycle
When weighing, each raw material in the Dihydromyricetin Bulk Powder has a unique traceability code, and this traceability extends throughout the entire process of extraction, purification, drying, and testing. Production parameters and quality inspection reports for each batch are electronically archived, enabling end-to-end information traceability from the field to the finished product.
