High Dietary Fiber Content (Dietary Fiber ≥ 59%): Delivers a high dietary fiber content (tested at 59.75%), offering excellent prebiotic intestinal support and low-calorie substitution for clean-label, low-carb food innovations.
RS2 Natural Crystalline Structure: Preserves the unique digestion-resistant physical structure of native Type-2 resistant starch, featuring an extremely low Glycemic Index (GI) and minimal small-intestinal absorption, making it an ideal core ingredient for blood sugar and weight management formulations.
High Whiteness & Superior Processing Compatibility: Boasts high whiteness (88.1%), exceptionally low moisture and ash, and a neutral, odor-free taste profile. It easily integrates into bakery, extrusion, and instant powder formulations without compromising the finished product's flavor or visual appeal.
Resistant Starch Type 2 (K130) is a high-purity dietary fiber ingredient derived from premium natural corn starch. As an RS2-type resistant starch, it retains its natural crystalline granule structure, resisting enzymatic digestion in the human small intestine and traveling directly to the large intestine. There, it functions as a high-quality prebiotic that nourishes beneficial gut microbiota and supports short-chain fatty acid (SCFA) production. Our K130 specification provides a total dietary fiber content of 59.75%, along with exceptional whiteness (88.1%) and low moisture (3.5%). It not only delivers stable fiber fortification for low-GI foods, meal replacements, and baked goods, but also acts as a texture improver and fat replacer in reduced-calorie formulations.
High-Concentration Prebiotic Dietary Fiber: Yields a tested dietary fiber content of 59.75%, providing an efficient daily fiber boost to foster gut health and microbiome balance.
Low-GI Blood Sugar Management Companion: Digestion-resistant properties ensure exceptionally slow absorption, preventing sharp glucose spikes and making it ideal for low-sugar, keto, and weight management applications.
Exceptional Color & Flavor Neutrality: Features a high whiteness score of 88.1% with a natural, neutral corn starch taste profile, ensuring zero off-flavors or unwanted color alterations in end products.
Optimal Particle Size & Fineness (100% Pass 100 Mesh): Fine powder texture allows uniform dispersion across dry mixes and dough matrices, enhancing formulation consistency.
Ultra-Low Moisture & Low Impurities: Moisture is tightly controlled at 3.5%, with sulfur dioxide and heavy metals kept far below food safety thresholds to power clean-label product claims.

Bakery & Biscuit Formulations (Calorie Reduction): In low-sugar, low-fat cookies, bread, and high-fiber biscuits, K130 can replace 10%–30% of standard flour. Due to its low water-binding capacity and non-swelling nature at room temperature, it maintains excellent dough handling and machineability while adding crispness to finished goods.
Instant Powders & Protein Blends: Pre-blends smoothly into whey proteins, plant-based proteins, and meal replacement shakes to boost fiber claims without inducing excessive viscosity or pastiness upon hydration, leaving a smooth mouthfeel.
Extrusion & Tablet Applications: Applied in nutrition bars, extruded cereals, and high-fiber chewables, its robust thermal stability ensures that the majority of its RS2 crystalline structure remains intact even after high-temperature processing.
Low-GI & Glucose Management Foods: Foods for diabetics, ketogenic (Keto) diets, glucose-control meal replacement cookies, and bread.
Dietary Supplements & Functional Powders: High-fiber meal replacement powders, prebiotic instant drink mixes, fiber capsules, and chewable tablets.
Bakery & Snack Foods: High-fiber bread, reduced-calorie cookies, energy bars, and extruded high-fiber breakfast cereals.
Meat Products & Low-Fat Sauces: Serves as a fat replacer and texture modifier in reduced-fat meatballs, sausages, and savory sauces.
Manufacturing Compliance: Produced in accordance with HACCP and ISO quality management systems, meeting national and international raw material standards.
Strict Heavy Metal & Residue Controls: Rigorously tested for pesticide residues, sulfur dioxide (≤ 30.0 mg/kg), and lead (< 0.10 mg/kg) to ensure pure and clean composition.
Non-GMO & Clean Label: Sourced from non-GMO corn raw materials without chemical modification, perfectly aligning with clean label market trends.

Q1: What is the difference between RS2 Resistant Starch and standard dietary fiber (or chemically modified starch)?
A1: RS2 is a naturally occurring resistant starch that maintains its native crystalline granule structure without chemical modification. Unlike water-soluble fibers, RS2 does not swell or bind large amounts of water at room temperature, ensuring doughs do not become sticky and drink mixes do not turn overly thick or gummy.
Q2: Does Resistant Starch K130 lose its resistant properties during high-temperature baking?
A2: RS2 structure exhibits remarkable heat stability under low-moisture, dry-heat processing conditions (such as in cookies and baked biscuits). As long as it is not subject to prolonged wet-heat gelatinization, its digestion resistance and dietary fiber functions remain largely intact.
Q3: Can I make a "High in Fiber" claim on my product package using Resistant Starch K130?
A3: Yes, K130 features a tested dietary fiber content of nearly 60%. Adding an appropriate dosage into your formulation will allow you to satisfy "Source of Fiber" or "High Fiber" label claims under most regional food labeling regulations.
Q4: Is this product suitable for Ketogenic (Keto) and low-carb diets?
A4: Absolutely. Because RS2 resistant starch is not converted into glucose in the small intestine, its net carbohydrate contribution is negligible. It does not cause blood sugar spikes, making it an excellent ingredient for Keto and low-carb baking.
Q5: Does the product contain any common allergens?
A5: Derived from corn, this product is naturally gluten-free and free from dairy, soy, peanuts, tree nuts, and all other major common allergens, making it safe for sensitive consumer groups.
