Extraction, characterization and antioxidant activity of water-soluble polysaccharides from Tuber huidongense

Single-factor experiment and Box–Behnken design were employed to optimize the ultrasonic-assisted extraction (UAE) of water-soluble polysaccharides from Chinese truffle Tuber huidongense (THWP). The optimal extraction conditions with an extraction yield of 7.17 ± 0.22% crude THWP were determined as follows: ultrasonic power 99.65 W, extraction time 40.39 min, ratio of water to raw material 24.65 mL/g, and extraction temperature 70.1 °C.
