Abstract: Orthogonal test design was employed to optimize the ultrasonic extraction of acorn tannin. The optimal extraction conditions were as follows: crude starch of acorn 2.0 g, ultrasonic power 300 W, 30% ethanol as extractant, temperature 30 ℃, extraction time 50 min,liquid-to-solid ratio 20:1. The maximum extraction efficiency obtained was 10.02% after 3 times extraction.

Key words: acorn tannin, orthogonal test design, ultrasonic extraction, ethanol
