Resistant starch types RS1, RS2, RS3, and RS4 are classified according to processing origin rather than functional efficacy.

Resistant starch types RS1, RS2, RS3, and RS4 are classified according to processing origin rather than functional efficacy.

Resistant starch types RS1, RS2, RS3, and RS4 are classified according to processing origin rather than functional efficacy. Among them, RS2 (naturally occurring in raw grains) is currently the only type with stable large-scale supply and extensive validation through numerous trials and commercial applications. RS4 offers favorable cost-effectiveness but faces regulatory constraints due to its classification as a chemically modified food additive. RS3 suffers from high production costs, low resistant starch content, and limited commercial viability. RS5 remains at the laboratory research stage. When selecting resistant starch, the primary evaluation criteria should be dietary fiber content and heat resistance performance.

The first batch of high-amylose resistant starch for 2026 has been successfully produced and warehoused.

Beijing Xiangyu, a key global supplier of resistant starch, has established an in-house end-to-end supply chain for RS2 resistant starch to ensure consistent quality, stable supply, and cost control. Since its founding seven years ago, the company has achieved year-on-year growth in market sales, with both production volume per batch and the total number of batches steadily increasing. The company’s first production batch of 2026—Xiangyu 1945-1946—has been completed with an output exceeding 1,000 metric tons. Additional production runs are scheduled for June and November 2026.

Beijing Xiangyu's non-standard small-packaged high amylose corn resistant starch (excluding samples)

Beijing Xiangyu's non-standard small-packaged high amylose corn resistant starch (excluding samples)

As a leading enterprise in the high amylose corn resistant starch industry, Beijing Xiangyu has become an important global supplier. Since its establishment, the company has only produced products in packaging specifications of 20kg, 25kg and 500kg, with customers being business clients such as food factories. With the gradual popularization of resistant starch among the public, individual consumers also have the intention to purchase it for personal use. Currently, the company does not provide products to individual consumers nor produce small-packaged products. Recently, small-packaged products of our company's models such as Xiangyu 1945 and Xiangyu K130 have appeared one after another on platforms including Pinduoduo, JD.com and 1688. Such products are neither produced or packaged by our company nor sold by our authorized distributors.

Sugar-free and low-GI do not equal blood-sugar reduction or weight loss

Sugar-free and low-GI do not equal blood-sugar reduction or weight loss

Our advice: start with the consumer job-to-be-done, then engineer formulation  and process to meet that need; let “zero sugar” or “low GI” ride along as a credible bonus claim, not the primary mission. Functional food must first taste great—no intake, no efficacy. Second, it must deliver a verifiable benefit at an affordable cost to earn repeat purchase. The buzzwords are only amplifiers.

Comprehensive Introduction to High-Amylose Resistant Starch

Comprehensive Introduction to High-Amylose Resistant Starch

As a high-quality carbohydrate, high amylose corn resistant starch differs from regular starch in structure, mechanism of action, and scientific validation; we also clarify how it contrasts with common dietary fibers. Functioning as a large-molecule, soluble dietary fiber, resistant starch offers proven advantages in glycemic control, weight management, and prebiotic effects while overcoming the texture, taste, and processing limitations of traditional fibers, making it a highly promising carbohydrate for widespread application.
