What can be made with sweet potato starch? From vermicelli and glass noodles to thickening agents, baked goods, and even industrial products like confectionery and glucose—sweet potato starch has a wide range of uses. Drawing on its extensive production experience, Qinhuangdao Tongyou Potato Industry outlines the primary applications of sweet potato starch.

Entering the facility of Qinhuangdao Tongyou Sweet Potato Industry Co., Ltd. in Lulong County, one finds the company in the midst of its peak season for sweet potato harvesting and processing. Established in 1992—evolving from the former Lulong County Shuangli Vermicelli Factory—the company is exceptionally busy this year. Production lines in the workshops are running continuously, while starch and vermicelli—much of it destined for overseas markets—lie neatly stacked in the warehouses, awaiting shipment.

Tongyou offers 400g Bag Handmade Sweet Potato Vermicelli for consumers, food distributors, and retailers seeking a versatile noodle product with traditional craftsmanship and convenient packaging. Made from sweet potato starch, this type of vermicelli is valued for its pleasantly chewy texture, ability to absorb sauces, and suitability for soups, stir-fries, hot pots, and other everyday dishes.

Recently, at the facility of Qinhuangdao Tongyou Potato Industry Co., Ltd. in Lulong, Hebei, a dark blue container truck bearing the "Qinren Shipping" logo was being loaded for export. A Heli forklift lifted pallets of finished goods—packed in woven bags—while workers neatly stacked them inside the container; the container was then sealed, ready for shipment to South Korea. For South Korean manufacturers of glass noodles and other food products—who constantly seek stable supplies of potato-based raw materials—the key question is: why source this batch of sweet potato starch from Lulong, China, rather than other production regions?

Amid the ongoing push for "Dual Carbon" goals and policies controlling both total energy consumption and energy intensity, traditional agricultural product processing enterprises face dual pressures regarding environmental compliance and cost control. For industries like sweet potato vermicelli production—which require continuous heat supply for processes such as starch slurry cooking, gelatinization, and drying—reducing energy expenditure while maintaining product quality is a critical challenge. Recently, Qinhuangdao Tongyou Potato Industry Co., Ltd., a company with over thirty years of experience in sweet potato processing, installed new thermal energy storage equipment, offering a practical model for energy-saving upgrades within the industry.

For distributors, restaurant chains, supermarket buyers, and food processors seeking consistent bulk supply, the 2.5kg Bag Sweet Potato Glass Noodles from Tongyou combine 100% sweet potato starch, commercial-scale packaging, traceable sourcing, and stable cooking performance for demanding foodservice and wholesale applications.
