Maca root polysaccharides (MRPs) prepared using DES-based UAE exhibited the highest yield and emulsifying properties, and showed significant effects in anti-diabetes and cholesterol reduction.
Maca is rich in bioactive compounds and has considerable potential for commercial application as a functional food material. In this study, maca root polysaccharides (MRPs) were prepared via hot water extraction, enzyme-assisted extraction, ultrasound-assisted extraction (UAE), and deep eutectic solvent (DES)-based UAE, and their physicochemical properties and biological activities were compared. The MRP obtained using DES-based UAE (MRP-DU) exhibited the highest yield (30.85%), oil-holding capacity (5.21 g/g), emulsifying capacity (50.58%), and emulsion stability (48.14%). Additionally, MRP-DU exhibited the highest antidiabetic and absorption-retarding effects on glucose and bile acid. These results suggest that MRP obtained using DES-based UAE have high application potential as functional food materials and could also serve as antidiabetic and cholesterol-lowering agents.
