- Abstract
In this study, tannin was extracted from mountain walnut shells with organic solvent method. The extraction rate of tannin was affected by various factors, including solvents, extraction temperature, extraction time, and solid-liquid ratios. L9(4) orthogonal experimental design was employed. The content of tannin in the extraction solution was determined with zinc ion complexometric titration method. According to the experimental methods, the optimal extraction conditions were as follows; extraction solvent water, extraction time 12 h, extraction temperature 50 °C, solid-liquid ratio 1:6.
