摘要： Tremella fuciformis polysaccharides (TPs) have attracted extensive attention as functional food constituents due to their bioactivity. However, beta-D-glucan obtained from TPs is readily degraded by oxidation and easy to absorb water and agglomerate. The purpose of this study was to reduce moisture adsorption and caking strength through spray drying by using maltodextrin as wall materials and explore the hypoglycemic effect and molecular mechanism of TPs microcapsules. It was observed that dextrose equivalent (DE) value and concentration of maltodextrin (MD) affect the morphology, encapsulation efficiency, loading capacity, water adsorption and caking strength of TPs microcapsules powder. The administration of TPs microcapsules powder prevented body weight and serum insulin loss, and significantly decreased the blood glucose level, serum triglycerides, as well as total cholesterol levels, which seemed to be related to increasing the glycogen synthesis and facilitating the glucose transportation by regulating the PI3K/Akt pathway.
