A dandelion leaf polysaccharide (DLP) with a sugar content of 46.53 ± 2.22% is isolated using ultrasonic‐assisted enzymatic extraction. The DLP contains two polysaccharide fractions with respective molecular weights (Mw) of 1900 and 22 800 g mol−1. Gas chromatography analysis reveals a composition of rhamnose, arabinose, mannose, galactose, and glucose. DLP displays excellent water holding and oil holding capacities, along with a moderate emulsifying activity and stability. Following simulated digestion in vitro, DLP can exist stably in the digestive system (saliva, gastric, and small intestine) without degradation. Furthermore, DLP possesses prebiotic properties and could be utilized as a carbon source.

Background: Kidney stone formation is closely related to renal epithelial cell damage and the adhesion of calcium oxalate crystals to cells. Methods: In this research, the adhesion of human kidney proximal tubular epithelial cells (HK-2) to calcium oxalate monohydrate crystals with a size of approximately 100 nm was studied. In addition, the inhibition of crystal adhesion by four tea polysaccharides (TPS0, TPS1, TPS2, and TPS3) with the molecular weights of 10.88, 8.16, 4.82, and 2.31 kDa, respectively were compared. Results: When oxalic acid-damaged HK-2 cells were repaired, cell viability increased. By contrast, reactive oxygen species level, phosphatidylserine eversion, and osteopontin expression decreased, thus indicating that tea polysaccharides have a repairing effect on damaged HK-2 cells. Moreover, after repairing the damaged cells, the amount of adherent crystals was reduced. The repair effect of tea polysaccharides is closely related to molecular weight, and TPS2 with the moderate molecular weight displayed the best repair effect. Conclusion: These results suggest that tea polysaccharides, especially TPS2, may inhibit the formation and recurrence of calcium oxalate kidney stones.

To minimize the serious environmental pollution caused by food byproducts, soybean curd residue was used as the substrate to ferment polysaccharides by Morchella esculenta. Water‐soluble crude polysaccharides (CMP) were purified by different gradient concentrations (30%, 60%, and 90%) of ethanol into three precipitation fractions. The experimental results indicated that the precipitated polysaccharides by the ethanol concentration of 60% (PMP) had the highest purity, containing rhamnose, arabinose, xylose, mannose, glucose, and galactose, with the molar ratio of 0.08:0.25:0.16:0.07:0.28:1.00. The physicochemical properties were revealed by SEM, AFM, FTIR, NMR, and Congo red test. Furthermore, the measurement of antioxidant activities in vitro demonstrated that PMP exhibited higher antioxidant capacities with the dose‐dependent manner than CMP and polysaccharides from unfermented soybean curd (USP). Overall, the results suggested that PMP had attractive functional activity which could be potentially utilized in functional food industries. Practical applications The polysaccharides from fungi sources are increasingly being used in functional food and pharmaceutical industry. In allusion to the problem of polysaccharides fermented by edible fungi, such as low yield, high cost, and hard to controllable. Soybean curd residue (SCR), a food waste, has been successfully used for the production of polysaccharides and graded ethanol was used to enhance polysaccharides production, lower the difficulty and homologous costs of purity. The results indicated that the purified polysaccharides displayed excellent antioxidant activities on scavenging DPPH and hydroxyl radicals. The outcomes of this work can provide technical support for comprehensive utilization of SCR and references for promotion and application of polysaccharides fermented from SCR via Morchella esculenta in food and medicine fields.
