In today's era of pursuing a healthy diet, resistant starch is reshaping the standard of prebiotic ingredients with its natural properties and scientifically proven efficacy. The core characteristics of resistant starch can be summarized in the following aspects，

As the only resistant starch (RS2) currently derived from natural crops, it is grown in a non-GMO enclosed environment, with only the "starch" ingredient in line with the clean label trend. The results showed that the enzymolysis rate of the raw material in small intestine was very low, and it had significant anti-sugar effect. It has been verified by Taiwan University and other institutions that it can increase the abundance of bifidobacterium by more than 30%, increase the yield of butyric acid by 50% compared with traditional prebiotics, and realize the detection of reducing sugar zero.

The product has achieved a breakthrough of 0.15 ultra-low water activity, high temperature processing resistance and no moisture caking, and has been successfully applied to solid drinks, nutrition bars and other non-heat process products. Relying on the whole industrial chain layout, its large-scale production cost is 40% lower than that of chemically modified prebiotics, and it has passed multiple certifications in Europe, America, Japan and South Korea, and is now exported to more than 10 countries on three continents.

Resistant Starch (RS)‌, with its natural properties and scientifically proven efficacy, is redefining prebiotic ingredient standards in today’s health-conscious era. The core characteristics of RS can be succinctly summarized as follows:

Resistant Starch as a Prebiotic :‌
The potential of RS as a prebiotic has been extensively researched and validated, primarily reflected in the following aspects:

1. ‌Promotion of Beneficial Bacteria Growth:‌
   RS is fermented by gut microbiota in the colon, selectively stimulating the growth of beneficial bacteria (e.g., Bifidobacterium, Lactobacillus). For example, brown rice rich in RS has been shown to significantly enhance the proliferation of probiotic strains.

2. ‌Improved Gut Microbiota Composition:‌
   Multiple studies demonstrate that RS intake alters the structure of gut microbial communities, increasing the abundance of beneficial bacteria while reducing harmful ones. A study by Shanghai Jiao Tong University School of Medicine found that RS supplementation significantly increased the abundance of Bifidobacterium adolescentis in the gut.

3. ‌Regulation of Gut Function:‌
   RS fermentation produces metabolites such as short-chain fatty acids (SCFAs), which modulate intestinal pH, strengthen the gut barrier, and reduce inflammation. These effects contribute to maintaining gut health and preventing intestinal disorders.

4. ‌Metabolic Health Benefits:‌
   RS consumption is linked to improved insulin sensitivity, reduced glycemic response, and lipid regulation. These benefits are partially mediated through gut microbiota modulation.

‌Advantages of RS as a Prebiotic:‌

• ‌Palatability‌: New texture—smooth, non-sticky, non-clumping, sugar-free core.
• ‌Moisture Resistance‌: Anti-caking, highly dispersible without additives, stable water activity for enhanced bacterial viability, high powder quality, and reduced processing risks.
• ‌Macromolecular Structure‌: Unique SDFP prebiotic supports microbial diversity, promotes butyrate production, minimizes bloating and diarrhea, and effectively proliferates Bifidobacterium and Akkermansia species.
• ‌Other Benefits‌: Zero detectable reducing sugars, neutral white powder with heat resistance, anti-glycation, anti-inflammatory, low-GI properties, and weight management support.
