Galactooligosaccharides Powder

Galactooligosaccharides Powder — Prebiotic Fiber Ingredient for Infant Formula, Functional Foods & Clinical Nutrition

More than 20 years of experience making Galactooligosaccharides Powder, Shaanxi Hongda Phytochemistry Co., Ltd. is a skilled company that makes and sells this product. The factory covers 20,000 square metres and has 10 or more advanced production lines and a purification workshop with a 100,000-level capacity. It can make 3,000 tons of goods every year. A food-grade lactose is transformed into GOS Powder using enzymes. It has a GOS purity of 57% to 90% (based on dry matter). A prebiotic element with cGMP, FSSC22000, ISO9001, ISO22000, HALAL, KOSHER, and VEGAN Certifications is fully tested and proven to meet global regulatory requirements.

What Is Galactooligosaccharides Powder?

Prebiotic fibre Galactooligosaccharides Powder is made from food-grade lactose using β-galactosidases to enzymatically transgalactosylate it. It can't be digested. With a degree of polymerisation (DP) of 2–8, the molecular framework is made up of a galactose unit connected to a central glucose molecule.

Powder is made up of mixtures of three, four, and five-saccharides connected by β(1→4) and β(1→6) bonds. Due to its structural similarity to Human Milk Oligosaccharides (HMOs), GOS is generally thought to be the best prebiotic for making baby formula.

It is more than just a source of fibre. A bifidogenic factor helps good bacteria, like Bifidobacterium infantis, grow while lowering the amount of bad gut flora.

Third-Party Test Report

Every batch of our GOS Powder is tested in-house and by third party laboratories such as SGS and Eurofins. Testing includes:

· HPLC-RI Sugar Profile: Confirms entire GOS fraction and separates residual Lactose, Glucose and Galactose

· Detection of pesticide residues

· Heavy Metal Analysis: Lead <0.5 ppm, Arsenic <0.5 ppm

· Microbial Limits: Salmonella (absent) Cronobacter sakazakii (absent, critical for infant grade) Coliforms (absent)

· Detection of aflatoxin M1 (traceability of dairy origin lactose)

· Nutrition Labelling & Natural Source Report

Test reports from third parties can be reviewed at your request before you decide to purchase.

Galactooligosaccharides Powder Advantages

Exceptional Thermal Stability

GOS Powder is stable for long durations at temperatures up to 160 °C and can be exposed for short periods to temperatures up to 180 °C. This enables it to survive HTST, UHT pasteurisation, extrusion and baking and retain its prebiotic activity.

Enhanced acid stability

GOS Powder is not hydrolyzed in acidic environment unlike Inulin or FOS, which are hydrolyzed at low pH (2.5). It is therefore appropriate for shelf-stable acidic beverages and fermented dairy products.

Clean Sensory Profile (

GOS has about 30-40% the sweetness of sucrose and does not have a metallic aftertaste. It is a bulking additive that increases mouthfeel of reduced-sugar formulations, without concealing flavours.

Bifidogenic Effectiveness

It specifically feeds Bifidobacterium species, which is the main method by which it is associated with digestive health, immunological function and mineral absorption advantages - especially Calcium and Magnesium .

Water Solubility: High

GOS Powder is soluble over 75% w/w at 25°C and gives clear, low viscosity solutions that can be used in beverages and liquid nutritional products.

Galactooligosaccharides Powder Application

Infant Formula

GOS is combined with FOS (usually at a 9:1 GOS:FOS ratio) to mimic the prebiotic profile of breast milk. Here we use 90% purity grade with zero tolerance for Cronobacter sakazakii and rigorous osmolality compliance.

Functional Dairy and Acidic Beverages

GOS is a fibre source that survives fermentation and low pH shelf conditions in yoghurts, fermented milks and fruit-based functional drinks. It also enhances texture by decreasing syneresis (liquid separation) without affecting flavour.

Clinical Nutrition & Dietetic Supplement

GOS is used in medical diets for older patients and for post-operative recovery. GOS helps absorb Calcium and Magnesium. It is a humectant and binder in protein bars and powder mixes that has a low glycemic index and prevents the products from hardening over time.

Production Process

Our GOS Powder is generated by a regulated enzymatic process:

1. Raw Material Selection: Food grade lactose from recognised dairy supply chains

2. Enzymatic transgalactosylation: Conversion of lactose to GOS chains (DP 2–8) by β-galactosidase enzyme

3. Purification & Fractionation Chromatographic separation to eliminate surplus monosaccharides and residual lactose to reach desired purity (57%, 70% or 90%)

4. Spray Drying: This process converts the concentrated GOS syrup into a free-flowing amorphous powder

5. Quality Testing HPLC-RI sugar profile, microbiological testing, heavy metal screening, moisture check

6. Package: Inner Packaging: Double-layer PE bag Outer packaging: Fibre drum Net weight per barrel: 25kg

All production batches are traceable from raw material to the discharge of the finished product.

FAQ

Q1: How does GOS Powder compare to FOS or Inulin in heat sensitive applications?

A: GOS Powder is much more stable. It is stable at 160°C and pH 2.5, conditions when FOS and Inulin generally hydrolyze to simple sugars and lose their prebiotic action. GOS is the safer bet for baked items and pasteurised beverages.

Q2: I am lactose intolerant – can I use this product?

A: GOS Powder Standard does contain residual lactose. For lactose-intolerant applications, request our high purity 90% GOS grade or lactose-reduced variations that are treated to minimise residual lactose content to below detectable levels.

Q3: What purity grades are available and when should I use each one?

A: 57% GOS is the norm for common food applications. 70% is incorporated in beneficial beverages and concentrated supplements. 90% is used in infant formula and clinical nutrition where low glycemic impact and low lactose content is needed.

Q4: Does GOS Powder add viscosity to my drink or dairy product?

A: No. GOS Powder solutions are low in viscosity and transparent, like sucrose solutions. Adds body and mouthfeel without acting as a thickening so your beverage texture remains clean.

Q5: What is the regulatory status in US, EU and China?

A: GOS is GRAS in the US, approved as a novel product in the EU, and explicitly permitted in China by GB regulations for infant formula and general foods.

Q6: Can you provide documents for compliance at the newborn grade?

A: Yes. We supply full baby grade documentation including Cronobacter sakazakii absence certificates, osmolality test reports, Aflatoxin M1 screening findings and third-party SGS/Eurofins certification.
