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.

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 food distributors, importers, and food-service buyers, finding a trustworthy supply of sweet potato vermicelli is a recurring headache. The market is flooded with products cut with corn starch or other fillers, and labeling rarely tells the full story about where the raw material actually came from. The real question is not just price, but whether the producer can trace every bag back to a known, controlled source.

The factory yard of Qinhuangdao Tongyou Potato Industry Co., Ltd. has been bustling recently, as a forklift smoothly loads pallet after pallet of bagged food-grade sweet potato starch into shipping containers. This shipment consists of 10 containers in total, bound for the South Korean market.
