What Is Food Grade D-Galactose Powder?
D-Galactose has been investigated in several pharmaceutical and clinical fields. Galactose-based microparticles were used in ultrasound contrast agents such as Levovist, while intravenous D-galactose was evaluated as a molecular chaperone in a reported case involving the cardiac variant of Fabry disease. Oral galactose has also been studied for focal segmental glomerulosclerosis (FSGS), although clinical results have been limited and inconsistent. Ultrasound contrast research, Fabry disease study, FSGS clinical trial.
D-Galactose supplementation has shown particular research interest in certain congenital disorders of glycosylation (CDG), especially PGM1-CDG and some SLC35A2-related disorders. Studies indicate that supplementation can increase UDP-glucose and UDP-galactose nucleotide-sugar pools, improve lipid-linked oligosaccharide fractions, and support improved galactosylation and sialylation. These findings relate to medically supervised, disease-specific protocols and should not be interpreted as therapeutic claims for food-grade D-galactose. PGM1-CDG pilot study, glycosylation study.
Food Grade D-Galactose is a purified, naturally occurring monosaccharide and aldohexose with the molecular formula C₆H₁₂O₆, molecular weight 180.16 g/mol, and CAS No. 59-23-4. It is also known as D-(+)-Galactose, D-Galactopyranose, D-Galacto-Hexose, Galactose Powder, or simply Galactose. It occurs naturally as a structural component of lactose, glycoproteins, glycolipids, and complex carbohydrates.
Although D-galactose has the same molecular formula as glucose, it is the C-4 epimer of D-glucose, meaning the two sugars differ in the spatial arrangement around one carbon atom. Unlike lactose, which is a disaccharide composed of glucose and galactose, D-galactose is an individual simple sugar. It provides mild sweetness, approximately 30% of the sweetness of sucrose, and functions as a reducing sugar in food processing.
BSH Ingredients supplies Food Grade D-Galactose Powder with ≥99% purity, a white crystalline appearance, and customizable particle size.

Forms of Galactose: D-Galactose, L-Galactose, Alpha and Beta Galactose
Galactose can occur in several stereochemical and structural forms. The main distinctions are between D-galactose and L-galactose, which are mirror-image enantiomers, and between α-D-galactose and β-D-galactose, which are anomers differing only in the orientation of the hydroxyl group at the anomeric carbon, C-1. Galactose may also form six-membered galactopyranose rings, five-membered galactofuranose rings, or a very small amount of open-chain aldehyde structure.
For commercial food, nutrition, supplement, and fermentation applications, D-Galactose Powder, CAS No. 59-23-4, is by far the most common and commercially important form. When ordinary food-grade D-galactose is dissolved in water, its α and β forms interconvert through mutarotation, producing an equilibrium mixture rather than remaining as a single anomer.
Comparison of the Main Galactose Forms
| Galactose Form | Structural Description | Popularity | Functions and Typical Applications |
|---|---|---|---|
| D-Galactose | Naturally predominant D-enantiomer, normally present as an equilibrium of several cyclic forms | Very high | Food ingredients, nutritional formulations, GOS and HMO synthesis, fermentation, dietary supplements, glycan production, and laboratory applications |
| α-D-Galactopyranose | Six-membered D-galactose ring with an α-configuration at C-1 | Low as an isolated commercial ingredient | Specialty carbohydrate synthesis, α-galactoside research, enzyme assays, glycan production, and analytical standards |
| β-D-Galactopyranose | Six-membered D-galactose ring with a β-configuration at C-1 | Moderate as a research material, but highly important biologically | Lactose, GOS, glycoprotein and glycolipid research, β-galactoside synthesis, enzyme studies, and specialty glycan manufacturing |
| α/β-D-Galactofuranose | Five-membered ring forms of D-galactose | Very low | Microbial glycobiology, pharmaceutical research, analytical standards, and synthesis of specialized glycoconjugates |
| L-Galactose | Mirror-image enantiomer of D-galactose | Very low | Plant metabolism research, vitamin C biosynthesis studies, specialty synthesis, and laboratory reagents |
| Open-Chain D-Galactose | Acyclic aldehyde form present only at trace levels in solution | Not sold as a normal ingredient form | Enables mutarotation and contributes to reducing-sugar reactions, including Maillard browning |
Alpha-D-Galactose vs Beta-D-Galactose
α-D-Galactose and β-D-Galactose have the same molecular formula, molecular weight, and D-configuration. They differ only at the anomeric carbon. In the α-form, the hydroxyl group at C-1 is oriented opposite to the C-5 hydroxymethyl group; in the β-form, the two groups are oriented on the same side.
In water, the β-D-galactopyranose form is generally predominant, accounting for approximately 64% of the equilibrium mixture. α-D-galactopyranose represents approximately 30% to 32%, while α- and β-D-galactofuranose together account for only a few percent. The open-chain aldehyde form remains at trace concentration. The exact distribution varies with temperature, solvent, concentration, and testing conditions. Research confirms that the β-anomer is energetically more stable in aqueous solution and that interconversion occurs through mutarotation. α-D-Galactose, β-D-Galactose, mutarotation research.
For food and supplement formulations, isolated α-D-galactose and β-D-galactose do not offer clearly established separate nutritional benefits because the free anomers interconvert after dissolution. Anomer-specific materials are more valuable in glycan synthesis, enzyme assays, biochemical research, pharmaceutical intermediates, and other stereochemistry-sensitive processes.
D-Galactose vs L-Galactose
D-galactose and L-galactose are enantiomers with the same formula, C₆H₁₂O₆, and molecular weight, 180.16 g/mol, but their three-dimensional arrangements are mirror images. Biological enzymes can distinguish between them, so they are not functionally interchangeable.
D-Galactose is naturally widespread in lactose, glycoproteins, glycolipids, oligosaccharides, and polysaccharides. It is the standard form used in food ingredients, nutritional products, GOS production, specialized carbohydrate synthesis, and human metabolic research.
L-Galactose is much less common as a commercial ingredient. It is best known as an intermediate in the plant pathway that produces L-ascorbic acid, or vitamin C, making it valuable mainly for plant biology, biochemical research, and specialty chemical synthesis. It does not have the same commercial availability or established food applications as D-galactose. Plant vitamin C biosynthesis research.
Galactopyranose vs Galactofuranose
Galactopyranose contains a six-membered ring and is the predominant structural form of free D-galactose in water. It is also the form most frequently found in mammalian glycans, lactose, GOS, glycoproteins, and glycolipids.
Galactofuranose contains a five-membered ring and is uncommon in mammalian glycans. It occurs in important surface glycoconjugates produced by certain bacteria, fungi, and parasites, so it is mainly used in microbiology, glycoscience, diagnostic research, and pharmaceutical development. Galactofuranose research.
Which Galactose Form Does BSH Ingredients Supply?
BSH Ingredients supplies Food Grade D-Galactose Powder with ≥99% purity, CAS No. 59-23-4. It is the commercially popular D-form and naturally establishes an α/β equilibrium when dissolved. It should therefore be identified as D-Galactose Powder, rather than exclusively as α-D-galactose or β-D-galactose.
The product is suitable for food formulations, dietary supplements, GOS and HMO manufacturing, fermentation, specialized nutrition, and other carbohydrate-processing applications. Buyers requiring an isolated anomer, L-galactose, isotopically labeled galactose, or another specialty derivative should request a separate identity, purity, CAS number, and stereochemical specification.
D-Galactose VS D-Glucose
D-Galactose and D-glucose are monosaccharides with the same formula, C₆H₁₂O₆, and molecular weight, 180.16 g/mol. They are C-4 epimers, differing only in the orientation of one hydroxyl group. This structural difference affects their sweetness, metabolism, glycaemic response, and applications.
| Property | D-Galactose | D-Glucose |
|---|---|---|
| CAS Number | 59-23-4 | 50-99-7 |
| Relative Sweetness | About 30% of sucrose | About 70% to 80% |
| Reported Glycaemic Index | Approximately 20 | 100 |
| Energy Value | About 4 kcal/g | About 4 kcal/g |
| Metabolism | Converted through the Leloir pathway | Directly enters glycolysis |
| Main Role | Glycan component and specialty carbohydrate | Primary energy source |
| Applications | GOS, HMO, supplements and functional foods | Sweeteners, beverages and rapid-energy products |
D-galactose generally produces a lower immediate glycaemic response and has milder sweetness than glucose. However, it is not a low-calorie sugar, since both provide approximately 4 kcal/g. D-galactose is preferred for specialized nutritional and carbohydrate-synthesis applications, while glucose is more suitable for economical sweetening and rapid energy.
Main Benefits of Food Grade D-Galactose Powder
Food Grade D-Galactose Powder is a multifunctional monosaccharide used in nutrition, food processing, fermentation, enzymatic research, biochemical media, protein production, and specialty carbohydrate synthesis.
- Plant-Derived and High Purity: BSH Ingredients supplies plant-derived D-galactose with ≥99% purity and controlled endotoxin levels. Avoiding lactose as the starting material reduces sourcing concerns related to dairy allergens and animal-origin BSE/TSE documentation, making supplier qualification easier for plant-based and sensitive applications.
- Lower-Glycaemic Energy Source: D-galactose has a commonly reported glycaemic index of approximately 20, compared with glucose at 100. It provides energy with a lower immediate glycaemic response and has only about 30% of the sweetness of sucrose. However, it still supplies approximately 4 kcal/g and should not be marketed as a low-calorie sugar.
- Infant and Specialized Nutrition: Galactose is a natural component of lactose, glycoproteins and glycolipids. It is used in infant and pediatric nutrition and serves as an important raw material for manufacturing galactooligosaccharides (GOS) and selected human milk oligosaccharides (HMOs). Claims concerning infant cognitive development must be supported by the finished formulation and applicable regulations.
- Optimized Protein Production: D-galactose can function as a carbon source and medium component in bioprocessing. In properly optimized cell-culture systems, replacing part of the glucose with galactose may reduce glycolytic lactate accumulation, support recombinant protein production and help tailor protein galactosylation or sialylation. Its effect on ammonia formation depends on the complete medium and nitrogen-feeding strategy. CHO cell-culture research, glycosylation study.
- Enzymatic and Biochemical Research: D-galactose is widely used as a nutrient-medium component, biochemical substrate and synthesis module. In engineered yeast, it can activate GAL1 and GAL10 promoters to induce recombinant protein expression, including specialized experimental proteins such as uncoupling proteins. Yeast expression research.
- Pharmaceutical and Chemical Synthesis: D-galactose is useful as a precursor for active pharmaceutical ingredients, a carrier-building component and a chiral building block for carbohydrate and glycan synthesis. BSH Ingredients supplies a food-grade product, so pharmaceutical or biopharmaceutical use requires separate customer qualification, application-specific testing and regulatory approval.
D-Galactose Powder Manufacturing Process
BSH Ingredients manufactures plant-derived D-Galactose Powder from gum arabic at its production facility in China. Gum arabic is dissolved in purified water and filtered before controlled sulfuric-acid hydrolysis. The solution is then neutralized with calcium hydroxide, decolorized using activated carbon, separated, and purified through ion-exchange processing. After concentration and crystallization, the D-galactose crystals undergo centrifugation, drying, crushing, sieving, and metal detection to produce 99% pure D-Galactose Powder.
Process flow:
Gum Arabic → Dissolution → Filtration → Hydrolysis → Neutralization → Activated Carbon Decolorization → Separation → Ion Exchange Purification → Concentration → Crystallization → Centrifugation → Drying → Crushing and Sieving → Metal Detection → Clean-Area Packaging
Drying and metal detection are managed as critical control points. Production and packaging follow HACCP, GMP, and ISO 22000:2018 quality-management principles.
Packaging
Standard bulk packaging consists of an inner PE liner and external round fiber drum, with a net weight of 25 kg/drum. Each drum is approximately 38 cm in diameter and 45 cm high. The standard pallet measures approximately 114 × 114 × 10 cm.
For qualified OEM finished-product orders, biodegradable and compostable pouch options and mineral-oil-free shipping boxes may also be available. These options are separate from the standard PE-lined bulk drum.
Food Grade D-Galactose Applications
Food Grade D-Galactose Powder is used in infant and pediatric nutrition, GOS and HMO production, dietary supplements, sports nutrition, clinical and enteral nutrition, functional foods, powdered beverages, dairy-free products, plant-based milk, bakery, confectionery, chocolate, fermentation media, enzyme research, cell-culture media, recombinant protein production, glycan synthesis, and pharmaceutical intermediate manufacturing. Its mild sweetness, reducing-sugar activity, low reported glycaemic index, and role as a building block for carbohydrate synthesis make it useful across food, nutrition, biotechnology, and specialty chemical applications. Pharmaceutical and biopharmaceutical uses require application-specific grade qualification.
Infant and Pediatric Nutrition
D-galactose is a natural component of lactose, glycoproteins, glycolipids, and milk oligosaccharides. Food-grade D-galactose can be incorporated into qualified infant and pediatric nutrition formulations or used to manufacture specialized carbohydrates for early-life nutrition. All applications must comply with local infant-formula regulations and finished-product safety requirements.
GOS and HMO Production
D-Galactose Powder is an important carbohydrate substrate for producing galactooligosaccharides (GOS) and selected human milk oligosaccharides (HMOs). Its high purity supports controlled enzymatic conversion, fermentation, downstream purification, and consistent oligosaccharide composition for prebiotic ingredients and specialized nutrition products.
Dietary Supplements and Specialized Nutrition
Food Grade D-Galactose can be used in supplement powders, capsules, tablets, sachets, sports-nutrition blends, and clinical or enteral nutrition products. It provides carbohydrate energy with mild sweetness and a lower immediate glycaemic response than glucose. However, D-galactose still supplies approximately 4 kcal/g and is not a low-calorie sugar.
Functional Foods, Beverages and Confectionery
D-galactose adds carbohydrate solids without excessive sweetness, making it suitable for functional beverages, powdered drink mixes, dairy-free products, bakery goods, chocolate, confectionery, and nutrition bars. As a reducing sugar, it also participates in the Maillard reaction, supporting desirable browning, crust development, aroma, and flavor in heat-processed foods.
