Brand: Dowell
SKU: 293961609

Products Description

Oligofructose, also known as Fructooligosaccharides (FOS), belongs to short‑chain fructan prebiotic fibers with polymerization degrees ranging from 2‑7. This water‑soluble non‑digestible carbohydrate can be produced either by enzymatic bioconversion from sucrose or physical‑enzymatic extraction & purification from chicory root and Jerusalem artichoke raw materials.

Built with β‑(2→1) glycosidic linkages between glucose and fructose units, FOS resists hydrolysis by human gastric and small‑intestinal digestive enzymes. Once delivered into the colon, it serves as a selective fermentable carbon substrate for resident beneficial microbiota including Bifidobacterium and Lactobacillus strains, supporting their targeted proliferation while restraining overgrowth of harmful gut bacteria.

During colonic fermentation, oligofructose generates abundant short‑chain fatty acids including acetate, propionate and butyrate. These metabolites adjust intestinal osmotic pressure, assist lipid metabolism modulation, and contribute to balanced serum cholesterol and triglyceride levels. Characterized by excellent water solubility, low caloric value, non‑cariogenic property and stable chemical performance, this raw material meets global compliance benchmarks for food processing as well as cosmetic formulation applications. It is offered in both food‑grade and cosmetic‑grade variants for multi‑sector formulation development.

Frequently Asked Questions

Q1: What is the difference between oligofructose FOS and inulin?

A: FOS is short‑chain fructooligosaccharide with DP 2‑7, while inulin covers broader polymerization degree. FOS features faster fermentation speed inside human gut and displays better water‑solubility performance for beverage and dry‑blend formulations.

Q2: What maximum daily intake should adults follow for safe consumption?

A: Recommended safe daily intake for adults stays within 20 g/day. Excessive intake may trigger temporary gastrointestinal bloating. Individual gut tolerance varies between different consumers.

Q3: Is this FOS powder suitable for vegan and vegetarian formula projects?

A: Yes. Our oligofructose powder is plant‑derived, non‑animal‑source, suitable for vegan, vegetarian and clean‑label product development. HALAL & KOSHER certifications are available.

Q4: Can oligofructose FOS be blended together with probiotic strains in one formula?

A: Absolutely. FOS works as prebiotic substrate for probiotics. Synbiotic compounding of FOS and viable probiotics is a common formulation solution for functional food and supplement products.

Q5: How to avoid caking problem during long‑term storage of bulk FOS powder?

A: Keep goods hermetically sealed, store under cool, dry and ventilated warehouse environment. Avoid high‑humidity surroundings. Once bulk drum is opened, finish usage as soon as possible and re‑seal tightly.

Q6: Can you deliver small‑batch trial order before mass‑volume purchase?

A: Yes. We support small trial batches, plus free 10‑50g lab samples for quality validation before formal bulk order confirmation.

Q7: What temperature range can oligofructose endure during food thermal processing?

A: It keeps stable under regular food baking and pasteurization conditions. Severe high‑temperature combined with extreme low‑pH environment may trigger partial molecular degradation; lab pre‑test for your exact processing condition is suggested.

Q8: What shipping alternatives are available for global bulk orders?

A: Express courier for small‑volume consignments; air freight for mid‑size bulk cargo; sea ocean freight for large‑volume container orders. We deliver worldwide, while import customs clearance work shall be handled by buyer's local agent.
