Product Introduction

The molecular formula for the product is C₆H₁₂O₆, and it is a naturally occurring aldohexose monosaccharide. C-4 epimer of glucose is made by enzymes breaking down lactose or fermentation-based processes.

The powder is crystalline, free-flowing, and colourless. It tastes slightly sweet, about 30–35% as sweet as sucrose. This substance's freezing point is between 163°C and 169°C, and its Specific Optical Rotation is between +79.0° and +82.0°. This is a key feature that sets it apart from glucose imitators.

A key ingredient in pharmaceutical intermediates, cell biology, and functional food manufacturing, it is structurally important for making glycoproteins and glycolipids.

Third-Party Test Report

Shaanxi Hongda partners with internationally recognized testing agencies — SGS and Eurofins — to conduct independent verification beyond in-house quality checks.

Third-party testing covers pesticide residue detection, natural origin reports, specific optical rotation, nutrition labeling, and endotoxin testing where injectable-grade compliance is required. All results are traceable per batch and available upon request.

D Galactose Powder Advantages

Verified Purity Above 99%

Production via enzymatic hydrolysis or fermentation achieves consistently high purity. HPLC assay confirms ≥98.5% on a dried basis — every batch.

Low Hygroscopicity

Compared to fructose, this galactose powder absorbs less moisture. Your powder blends stay free-flowing longer, reducing caking risk in storage and formulation.

Stable Identity Verification

The Specific Optical Rotation (+79.0° to +82.0°) provides a reliable analytical fingerprint. This protects you from glucose substitution fraud during procurement.

Multi-Grade Compliance

Specifications align with USP, EP, and BP — supporting regulatory submissions in the US, EU, and UK markets without reformulation.

Allergen-Aware Sourcing

Fermentation-based production routes are available for buyers who need non-animal-origin documentation — essential for vegan, dairy-free, and allergen-free label claims.

D Galactose Powder Application

Pharmaceutical Intermediates

Used as a precursor in the synthesis of Tagatose and various APIs. It serves as a carrier excipient in diabetic-friendly drug formulations where minimal insulin response is required. Low-endotoxin grades support parenteral applications with Bacterial Endotoxin Test (BET) documentation.

Cell Biology & Diagnostics

D Galactose Powder is a standard component in bacteriological agar and cell culture media. Researchers use it to induce aging models in rodents, making it a widely used reference compound in anti-aging drug screening studies.

Functional Food & Infant Nutrition

As a structural component of Galactooligosaccharides (GOS), it is used in prebiotic supplements and infant formula. In sports nutrition, it provides sustained energy release without the rapid glycemic spike of glucose — relevant for endurance product formulation.

Bakery & Specialty Food

As a reducing sugar, it participates actively in the Maillard reaction, producing controlled browning and flavor development in baked goods.

Production Process

Raw material sourcing begins at Hongda's supervised planting bases, with professional agronomists overseeing traceability. Lactose-derived or fermentation-route galactose is processed through enzymatic hydrolysis under controlled pH and temperature conditions.

The extraction passes through 100,000-level purification workshops before crystallization, drying, and milling to target particle size. Each batch undergoes HPLC assay, LOD measurement, heavy metal testing via ICP-MS, and full microbiological screening before release.

Pre-shipment testing covers pesticide residues, moisture, heavy metals, and microbial counts — all documented in a batch-specific COA.

FAQ

Q1: What is the normal purity of your product?

A: Assay purity is ≥98.5% on a dried basis, confirmed by HPLC. Production batches consistently reach above 99%.

Q2: Is this product compatible with vegan or dairy-free products?

A: Yeah. Production routes based on fermentation exist. You can request a Non-Animal Origin certificate to help you claim your product as meeting vegan standards.

Q3: How can galactose powder be stored to prevent caking?

A: Store in well sealed containers below 25°C at relative humidity less than 60%. LOD is regulated to ≤1.0% to avoid caking due to moisture.

Q4: Is it applicable for injectable pharmaceutical applications?

A: Food grade powder is not suited for parenteral usage. You will need to specify Low Endotoxin / Injection Grade with Bacterial Endotoxin Test (BET) documentation contained on the COA.

Q5: How is galactose different from glucose in formulation?

Q: Galactose is less soluble than glucose at normal temperature. A: For liquid formulations, provide somewhat longer mixing time or warm water.

Q6: What about the MOQ and lead time?

A: Please reach out directly to our staff. MOQ and lead times are dependant on grade, volume and customisation requirements. Samples can be obtained.
