Resistant starch, as a new type of prebiotic, is gradually gaining market recognition. As a novel product, many customers are not yet fully aware of its principles, effects, and unique features. As a global supplier of resistant starch, our company has accumulated a substantial number of prebiotic customers, and we would like to share the main information points with our valued customers.

1. The fundamental support of resistant starch as a prebiotic lies in its primary nutritional offering, which is dietary fiber content, that is, carbohydrates that cannot be absorbed by the small intestine. In a broad sense, it meets the definition of a prebiotic. The dietary fiber content of our Qianyin Xiangyu series of resistant starch is over 50%, and based on customer feedback, the taste and effectiveness are both very good.

2. In terms of effects, resistant starch, based on its complex dietary fiber characteristics, is more balanced in meeting the nutritional needs of different types of prebiotics compared to conventional prebiotics, especially those required by unique bacterial strains such as AKK bacteria. This leads to a comprehensive range of fatty acid types and a balanced abundance, avoiding the side effects caused by high concentrations of a single type of fatty acid due to a single type of prebiotic. At the same time, it ensures that necessary prebiotics do not lack proper nutrition. There are many academic papers on this level, such as the recent paper published by Shanghai Jiao Tong University in "Nature". In terms of consumer experience, the effects on promoting bowel movements for conditions like diarrhea and constipation are very noticeable.

3. There are many unique aspects to resistant starch as a prebiotic. Firstly, it contains a large molecular fragment of dietary fiber that is insoluble in alcohol (SDFP), which ferments better and has lower osmotic pressure, making it relatively more friendly to the gastrointestinal tract, and it is also a unique type of dietary fiber in resistant starch. Secondly, its low water activity gives it advantages in extending shelf life and reducing the production costs of probiotics. Additionally, resistant starch has a very low viscosity, especially in prebiotic application scenarios, it does not react with viscosity, and some customers use it as a dispersing agent, which decomposes quickly without clumping; it has a good flavor, belonging to a very light, tasteless, original grain fragrance, avoiding the sweet and greasy feeling of commonly used prebiotics. The K130-109 series products developed by Qianyin Xiangyu, which are regulated as solid beverages, have low moisture, almost zero microbes, and high standards in fineness, whiteness, and packaging specifications, and are well received by customers in the prebiotic field. At the same time, they also stand out in the effects for weight loss and low GI foods.
