Products Description

Pregelatinized Sweet Potato Starch is a modified‑starch product manufactured from native sweet‑potato starch through high‑temperature gelatinization, drying and pulverization. Unlike raw native starch, it is pre‑gelatinized. It fully swells and gelatinizes under stirring in cold water, with no additional cooking required. It retains the strong bonding performance inherent to sweet‑potato starch, delivering favorable film‑forming and water‑holding capacity. Its paste boasts high stability and is less prone to retrogradation, stratification or precipitation. The fine, homogeneous powder contains minimal impurities and mixes well with a wide range of powdered auxiliary materials.Pregelatinized Sweet Potato Starch is widely used in foundry, feed, building materials, handicrafts and certain food‑processing sectors. It acts as a binder, thickener, water‑retaining agent and shape‑setting agent. It streamlines production workflows, lowers equipment investment and improves the forming quality of end‑products, making it a highly practical natural bonding raw material.

Product Advantages

Convenient Cold Dissolution

High‑temperature cooking steps are eliminated. It dissolves rapidly into a homogeneous paste in clean water at ambient temperature, greatly simplifying operational workflows and lowering production‑stage energy consumption.

Superior Bonding Performance

Pregelatinized Sweet Potato Starch offers outstanding adhesive capacity. It forms stable connections between different materials and improves the overall structural compactness and durability of finished goods.

Natural & Safe

Produced from native sweet‑potato starch without harmful additives, it has no peculiar odor and is suitable for various compliant manufacturing and application scenarios.

High Compatibility

It demonstrates good adaptability to most conventional materials without adverse incompatibility reactions, and can be flexibly integrated into existing formulation systems across different industries.

Easy Storage & Transportation

It maintains stable properties under normal conditions and resists deterioration and caking. No complex special control measures are required for long‑distance shipment or prolonged storage.

Working Principle

Molecular Hydration

Upon contact with cold water, pre‑treated starch molecules rapidly bind with water molecules and complete spontaneous swelling and dispersion.

Structural Unfolding

The originally compact and ordered structure of starch granules is pre‑disrupted. Molecules fully unfold in water without heating to form homogeneous colloids.

Gelatinization & Shape‑building

Gelatinization takes place at ambient temperature rather than under high‑heat input, directly generating a stable viscous paste system.

Performance Activation

Modified molecular chains disperse evenly throughout the system and fully release preset functional properties such as thickening and bonding.

Stable State Maintenance

Even molecular distribution within the formed paste prevents stratification and sedimentation and sustains stable performance over an extended period.

Application Scope

1. Food Processing

Pregelatinized Sweet Potato Starch serves as a thickener and stabilizer in food manufacturing. It optimizes product texture and morphology and delivers a finer, smoother mouthfeel for food products.

2. Building‑material Production

When blended into building‑material formulations, it provides water‑retention and thickening effects, optimizes construction workability and enhances structural stability.

3. Feed Processing

Added to various feed products, it improves pellet formability and reduces scattering and material waste to meet feeding requirements.

4. Foundry Industry

Used as an auxiliary sand binder, it improves sand‑core formability, enhances casting surface smoothness and minimizes defects.

5. Papermaking Retention Aid

Incorporated into papermaking workflows, it raises the fiber retention rate, improves paper uniformity and enhances the surface finish of finished paper.

Product Precautions

01/

Unopened products should be stored in dry, well‑ventilated environments and kept away from direct moisture to avoid moisture‑induced caking that impairs product performance.

02/

Prepare paste with clean fresh water; keep grease, foreign particles and impurities out to preserve paste purity and functional performance.

03/

Pregelatinized Sweet Potato Starch is an organic powdery substance. Keep it away from open flames and heat sources during storage and handling to prevent potential safety hazards.

04/

Control stacking height during warehousing. Avoid excessive heavy compression to prevent particle deformation that compromises subsequent dissolution and dispersion performance.
