Discrepancy on the quality characteristics of soluble dietary fiber in wild Rosa roxburghii Tratt fruits from different regions.

To minimize waste and maximize the utilization of wild Rosa roxburghii Tratt fruits, the quality characteristics of soluble dietary fiber (SDF) extracted from wild Rosa roxburghii Tratt fruits sourced from ten regions were assessed in this study through an in-depth analysis. This analysis included the evaluation of chemical composition, physicochemical properties, structural elucidation, antioxidant capacity, and functional properties in yogurt applications. Communally, these SDFs are acidic heteropolysaccharides mainly composed of glucose, galacturonic acid, galactose, arabinose, and rhamnose, and all of them showed the infrared spectrum and high molecular weight (Mw) characteristics of polysaccharides.
