Dietary Fiber & Prebiotics – Dual‑Benefit Ingredients for Digestive & Metabolic Health

Consumers need more fiber – but they also want prebiotic benefits. Saigao’s dietary fiber & prebiotics portfolio combines soluble dietary fibers (resistant dextrin, inulin, polydextrose) with short‑ and long‑chain oligosaccharides (FOS, GOS, XOS, IMO) to deliver both digestive regularity and targeted microbiome support. Every ingredient is fermentation‑derived, vertically integrated, and backed by full transparency. Formulate for gut health, immune support, calcium absorption, or blood glucose management – all with clean‑label compatibility.

Dietary Fiber & Prebiotics

Soluble Dietary Fibers – Bulk, Regularity & Metabolic Health

Dietary fiber is essential for digestive health, but not all fibers are equal. Our soluble fibers are highly fermentable, low‑viscosity, and easy to formulate.

Resistant Dextrin: A clean‑tasting, clear‑soluble fiber that resists upper digestion. It is slowly fermented in the colon, producing butyrate – a short‑chain fatty acid that supports gut barrier integrity. Ideal for clear beverages, meal replacements, and functional waters. Typical dosage: 8–15 g/day for digestive regularity.
Inulin (from chicory root): Long‑chain inulin adds creamy mouthfeel and prebiotic effects. It stimulates Bifidobacteria growth, improves stool frequency, and enhances calcium absorption. Perfect for high‑fiber yogurts, baked goods, and nutritional powders.
Polydextrose: A low‑calorie (1 kcal/g) bulking fiber that improves stool softness and frequency. Thermally stable for baked goods, extruded cereals, and frozen desserts. It also helps maintain moisture in reduced‑sugar formulations.

All three are classified as dietary fiber by FDA, EFSA, and CODEX. We provide AOAC fiber analysis (method 2009.01, 2011.25) with every batch.

Prebiotic Oligosaccharides

Prebiotic Oligosaccharides – Targeted Microbiome Modulation

Prebiotics are non‑digestible compounds that selectively stimulate beneficial gut bacteria. Our oligosaccharides are scientifically validated prebiotics with distinct fermentation profiles.

FOS (Fructo‑oligosaccharides): Short‑chain prebiotic that rapidly ferments in the proximal colon. Strongly stimulates Bifidobacteria and Lactobacilli. Ideal for low‑dosage gut health shots, yogurts, and infant nutrition.
GOS (Galacto‑oligosaccharides): Mimics human milk oligosaccharides. Gentle fermentation, well‑tolerated. Excellent for adult digestive health and senior nutrition.
XOS (Xylo‑oligosaccharides): Highly selective for Bifidobacteria with a low effective dose (1–2 g/day). Heat and acid stable – perfect for baked goods, bars, and acidic beverages. Low FODMAP certified.
IMO (Isomalto‑oligosaccharides): Slow‑fermenting, extends prebiotic activity throughout the colon. Provides mild sweetness and low viscosity.

Synergy strategy: Blend short‑chain (FOS) and long‑chain (inulin or XOS) prebiotics for a “full‑colon” effect. Our R&D team can help you design synbiotic systems with probiotic strains (formulation support only).

We provide batch‑specific prebiotic activity assays (e.g., fermentation rate, short‑chain fatty acid production, bacterial enumeration).

FAQs

FAQ – Diabetes & Saigao Ingredients

What is the difference between dietary fiber and prebiotics?

All prebiotics are dietary fibers, but not all dietary fibers are prebiotics. Prebiotics must (1) resist digestion, (2) be fermented by beneficial gut bacteria, and (3) selectively stimulate their growth or activity. Our inulin, FOS, GOS, XOS, and resistant dextrin meet these criteria. Polydextrose has prebiotic effects but is primarily classified as a bulking fiber. We provide scientific documentation to support your preferred claim.

What are the recommended daily intakes for your fiber and prebiotic ingredients?

Ingredient	Typical effective dose (g/day)
Resistant dextrin	8–15
Inulin	5–10
Polydextrose	8–12
FOS / GOS	2–5
XOS	1–3
IMO	5–10

Lower doses (1–2 g) provide mild prebiotic effects. We help you formulate to meet “source of fiber” (≥3g/serving) or “high fiber” (≥6g/serving) label claims.

Are these ingredients suitable for low‑FODMAP diets?

Some individuals with IBS or SIBO may react to rapidly fermented prebiotics (FOS, inulin). For low‑FODMAP formulations, we recommend XOS (certified low FODMAP) or resistant dextrin (slow fermentation, well‑tolerated). We provide FODMAP analysis for each batch to help you target sensitive consumer segments.

Can I make a “prebiotic” or “supports digestive health” claim using Saigao ingredients?

Yes. Many of our customers formulate products that address multiple metabolic conditions simultaneously:
- Low glycemic + low calorie (maltitol, polydextrose)
- Low glycemic + prebiotic fiber (inulin, FOS, XOS)
- Low glycemic + appetite control (resistant dextrin slows gastric emptying)
This makes Saigao ingredients highly versatile for diabetic, prediabetic, and metabolic syndrome populations.
