South Korea's HanAll F&B Farming Association Corporation filed a patent application in June for a rice noodle manufacturing method designed to reduce dependence on a single rice variety — a move the Taebaek, Gangwon Province-based producer says could open the category to a wider field of manufacturers and regional grain sources.
The patent follows roughly three years of process R&D that consumed approximately 6 tons of rice flour. The core technical challenge the company addressed was raising the domestic rice content of noodles to 50% or higher while using flour milled from multiple rice varieties — a threshold that proved difficult to clear with conventional methods. HanAll F&B said its research centered on improving noodle separability, the property that keeps finished noodles from clumping, which is a persistent manufacturing constraint in rice-based pasta and noodle formats.
Expanding the Product Platform
With the patent application filed, the company is treating the intellectual property not as an end product but as a technical foundation. Its stated next targets are rice pasta and rice naengmyeon — the chilled, chewy Korean cold-noodle format increasingly visible in Asian-cuisine segments of foodservice and retail. The two formats demand materially different processing parameters than a standard rice noodle, so HanAll F&B is pursuing manufacturing technology and product development in parallel rather than sequencing them.
The strategic logic is straightforward for a company that built its initial manufacturing base on wild mountain greens and regional specialty foods: extending existing food-processing infrastructure into rice noodles broadens the addressable product range without requiring a full greenfield investment. The company applies hygiene management protocols from the raw-ingredient washing stage and has refined aging and formulation processes over time — disciplines it considers transferable to grain-based noodle production.
Market Implications for Operators
For foodservice buyers and distributors, the significance of HanAll F&B's patent lies less in a single company's output and more in what a variety-agnostic manufacturing method could mean for ingredient availability and price stability across the Korean rice noodle category. Rice noodles have gained consistent menu penetration in Asian QSR, fast-casual, and ramen-adjacent concepts globally, and supply constraints tied to specific grain varieties have been a known friction point for volume buyers.
HanAll F&B has signaled it will engage directly with domestic and international buyers to test market response and gather demand signals, framing buyer conversations as a feedback loop for future product and channel decisions. Whether that outreach yields distribution agreements or co-development partnerships with larger foodservice manufacturers remains to be seen, but the company's stated ambition — enabling many manufacturers to produce many types of rice noodle — positions the patent as a potential licensing or technology-transfer asset rather than a purely proprietary SKU advantage.
The broader rice-noodle segment, bolstered by gluten-free positioning and growing consumer familiarity with Korean cuisine formats, gives the company a favorable category tailwind as it moves from R&D into commercial development.
