Sweet Potato Starch

// Product Advantage // 

1. High Purity & Low Impurity Content

Our sweet potato starch adopts a multi-stage centrifugal screening and fine filtration process, with a whiteness ≥92% and an impurity content controlled below 0.15%. It is free of sand, fiber, and black spots, ensuring a pure white appearance and stable quality, which meets high‑standard food‑grade requirements.

2. Excellent Viscosity & Gel Stability

With a peak viscosity ≥1200 BU and outstanding retrogradation resistance, it forms a tough, transparent gel after heating and cooling. It maintains stable texture in low‑temperature storage, effectively preventing syneresis and layering, ideal for noodles, jelly, and frozen food.

3. Natural Non‑GMO & Clean Label

Made from fresh, non‑transgenic sweet potatoes without added chemicals, preservatives, or bleaching agents. It is gluten‑free, allergen‑free, and fully complies with international food safety standards (ISO, HACCP), supporting clean‑label positioning for health‑conscious consumers.

4. Strong Water Binding & Expansion Capacity

Features superior water retention and expansion ratio (water absorption ≥75%). It improves elasticity, chewiness, and yield in meat products, noodles, and pastries, reducing cooking loss and enhancing product texture and overall quality.

5. Stable Supply & Consistent Batch Quality

Supported by a large‑scale standardized production base and fully automated production lines, we ensure batch consistency (CV ≤3%) and stable annual supply. Strict SGS testing guarantees reliable quality for long‑term cooperative customers.

Production of Traditional Staple Foods (Vermicelli & Noodles)

Sweet potato starch is the core raw material for making sweet potato vermicelli and sheet jelly. With its high viscosity and strong gelling properties, the resulting noodles remain chewy and intact after prolonged boiling, making them ideal for hot pot, sour spicy soup and stews. It is a key ingredient in many classic regional dishes across China.

Chinese Culinary Use: Batter Coating & Thickening

Widely used for batter coating in fried dishes such as crispy pork and fried chicken, sweet potato starch forms a crisp, non-soggy crust that stays firm even after refrying. It also works great for tenderizing meat by locking in moisture when used as a marinade coating, delivering juicy, tender results.

Desserts & Specialty Pastries

Its excellent gelling ability makes sweet potato starch perfect for thickening and setting traditional desserts like red bean soup and sesame paste. It is also used to make sweet potato rice cakes, steamed meat coatings, and specialty dumplings in various regions, offering a uniquely soft yet resilient texture.

Food Industry Deep Processing

Modified sweet potato starch serves as a thickener and stabilizer in baked goods and beverages. It can also be further processed into starch syrups such as maltose syrup and high-fructose syrup, acting as a cost-effective alternative to sugar in large-scale food manufacturing.
